• SQL query question, how to improve it?

  Hello everyone, I want to create a query with result in the following output. Each first-person Department starts with the letter A and goes to the top like this:
  
  Name Department
  A Person1 3
  B Person2 3
  C channels3 3
  D Individu4 3
  Person10 E 3
  
  A 10 Person6
  Person7 10 B
  Person8 C 10
  
  An Individu4 13
  B Person9 13
  
  
  It must be a SQL query, unfortunately no PL/SQL
  
  I was able to create this query, but its lack. Department_id will be a variable, a person can choose a Department or several departments, so the request varies in size.
  
  Select department_id, chr (64 + rownum)
  from (select name, department_id
  employees
  where department_id = 3
  order of id_but, naam
  )
  Union
  Select department_id, chr (64 + rownum)
  from (select name, department_id
  employees
  where department_id = 10
  order of id_but, naam
  )
  Union
  Select department_id, chr (64 + rownum)
  from (select name, department_id
  employees
  where department_id = 13
  order of id_but, naam
  )
  order of id_but, naam
  
  
  
  The employees table has the following columns:
  ID, name, department_id
  
  Can someone help me with this query? Perhaps with the With clause?

  Hello

  You can use the analytic ROW_NUMBER function instead of ROWNUM. Like all analytical functions, ROW_NUMBER can do a calculation separated for each unique value in the PARTITION BY clause:

  select        chr ( 64
             + ROW_NUMBER () OVER ( PARTITION BY  department_id
                           ORDER BY        id_but
                           ,             naam
                         )
             )     AS r_num
  ,        name
  ,       department_id
  from       employees
  where       department_id     IN (3, 10, 13)
  order by  id_but
  ,       naam
  ;
  

  If you do this in SQL * Plus, you can save for the departemnts user input (if it is a list separated by commas as ' 3, 10, 13', or a single value as "99") in a substitution variable (let's call it deptartment_id_list) and use the following WHERE clause:

  where       department_id     IN (&department_id_list)
  

• SQL query question

  I have a table named Test, data inserted as below

  col1	Val
  There	3
  x	1
  z	2

  We write a query to output below:

  col1	Val
  x	1
  There	2
  z	3

  Please suggest the best way to reach above result.

  It is not clear what you're trying to do, but you can use something like:

  Select col1,

  ROW_NUMBER() (any order of col1) val

  of the test

  /

  For example:

  with the trial as)

  Select 'x' col1, 3 val union double all the

  Select 'y', 2 double Union all

  Select 'z', 1 double

  )

  Select col1,

  ROW_NUMBER() (any order of col1) val

  of the test

• SQL Query Question of multiple criteria

  Hi all

  I currently have a query that provides me with a count for a criterion (C), but I also want to include the number of criteria (A) and (E) within the same query if possible. Here's what I have:

  SELECT B.MDA_LEV3_DEPT_NAME AS "TEU Area", AS COUNT (Z.MDA_EPAF_STATUS) PROJECT

  PS_MDA_EPAF_RQST Z, PS_MDA_EMPLOYEES B, PS_MDA_EPAF_WFXREF T

  WHERE MDA_EPAF_STATUS = 'C '.

  AND T.ORIGINATORID = Z.USERID

  AND Z.USERID = B.EMPLID

  AND Z.TRANSACTION_NBR = T.TRANSACTION_NBR

  B.MDA_LEV3_DEPT_NAME GROUP

  ORDER BY B.MDA_LEV3_DEPT_NAME;

  Which produces:

  Area of EVP	Project Manager
  Office of VP University Affairs Sr	5
  Cancer medicine	30
  Cancer medicine - research	49
  Cancer Prev & Pop science	3
  Cancer Prev & science-Res Pop	1
  Diagnostic Imaging	2

  Provost and EVP departments	1
  Radio-Oncology	26
  Radio-Oncology - search	2
  Regulatory Affairs	1
  Surgery	4
  Vice Provost research clinical	1
  Vice Provost Science	42

  But I want to understand (A) approved County and (E) which is pending County so it would look like:

  Area of EVP	Project Manager	County approved	County pending
  Office of VP University Affairs Sr	5
  Cancer medicine	30
  Cancer medicine - research	49

  Cancer Prev & science-Res Pop	1

  Provost and EVP departments	1
  Radio-Oncology	26
  Radio-Oncology - search	2
  Regulatory Affairs	1
  Surgery	4
  Vice Provost research clinical	1
  Vice Provost Science	42

  Maybe (guessing)

  SELECT B.MDA_LEV3_DEPT_NAME AS 'TEU Area. "

  PROJECT COUNT(CASE Z.MDA_EPAF_STATUS WHEN 'C' THEN 1 END) AS,

  COUNT(CASE Z.MDA_EPAF_STATUS WHEN 'A' THEN 1 END) APPROVED,

  AS COUNT(CASE Z.MDA_EPAF_STATUS WHEN 'P' THEN 1 END) PENDING

  OF PS_MDA_EPAF_RQST Z.

  B PS_MDA_EMPLOYEES,

  PS_MDA_EPAF_WFXREF T

  WHERE MDA_EPAF_STATUS ('C', 'A', 'P')

  AND T.ORIGINATORID = Z.USERID

  AND Z.USERID = B.EMPLID

  AND Z.TRANSACTION_NBR = T.TRANSACTION_NBR

  B.MDA_LEV3_DEPT_NAME GROUP

  ORDER BY B.MDA_LEV3_DEPT_NAME

• SQL query and question CFOUTPUT

  Hello

  I am trying to compare two tables in a database.  I need a few fields in a table of output, to compare a field between the two tables.  Users choose the tables.  I've written a SQL query that does what I need:

  < cfquery name = "getitems" datasource = "snapshot" >
  Select #endtable # .field9 #endtable # .field12, #endtable # .field4, #endtable # .field13, #endtable # .field2, #endtable # .field3, #starttable # .field3
  of #endtable #, #starttable #.
  "where #endtable # .field5 =' #form.field5 #"
  and #starttable # .field2 = #endtable # .field2
  < / cfquery >

  Problem is on the output.  You can see that I am selecting field3 in two tables.  I want also to two output field3 values.

  < cfoutput query = "getitems" >

  #field3 #.

  < / cfoutput >

  This gives me the value that was chosen as #endtable # .field3.

  How can I exit the other - .field3 of # #starttable?

  As mentioned, the table names are variable being passed in the query...  Thank you!

  Peter

  How can I exit the other - .field3 of # #starttable?

  Use an alias to give different names fields IE table.column AS unnom. Otherwise, cfquery do not know what field do you mean when you say "field3".

  Select #endtable # .field9, #endtable # .field12,.

  Be careful when using this type of sql. According to the source of your variables, this can pose a risk of sql injection.

• Question to convert oracle sql query

  Hi friends,
  
  I have a sql query, as follows,

  Select Name From SysObjects Where XType = 'U' And Name = @Name

  I want to convert this to oracle. I tried to convert this in someways. But I get errors only. Please someone help me solve this problem.
  
  Thank you
  RAM

  Views of the Oracle dictionary more come in DBA_, ALL_ USER_ flavors. You probably don't have privileges to view DBA_OBJECTS, in which case try object or USER_OBJECTS.

  Of after what I read, you may need something like

  SELECT * FROM all_objects WHERE owner <> 'SYS' AND object_type = 'TABLE'
  

  BTW, a sure way to liquidate Oracle professionals is to use "SQL" to designate another DBMS product, not Structured Query Language. As you may have noticed, we have SQL here as well.

• Single SQL query for the analysis of the date of customs declaration under the table of Stock codes

  Dear all,

  
  

  Please tell us a single SQL query for the below,
  

  We have a Table of Stock as shown below,

  STOCK_TABLE

   

  ITEM_CODE (item code)

  BAT_NO

  (lot no.)

  TXN_CODE

  (transaction code)

  DOC_NO

  (number)

  BOE_DT

  (date of the customs declaration)

  I1

  B1

  I1

  I2

  I3

  I4

  B80

  I5

  B90

  T102

  1234

  JULY 2, 2015

  I6

  B100

  We have to find the date of customs declaration (i.e. the date when the items have come under this particular table) for items that are not attached to any document (that is, who have TXN_CODE, DOC_NO and BOE_DT fields with a NULL value).

  For each item in the table of actions, which is not attached to any document, the customs declaration date is calculated as follows.

  1. If (code section, lot number) combination is present under HISTORY_TABLE, the date of customs declaration will receive the UPDT_DT, the transaction code (TXN_CODE) is an IN or transactions (which can be analyzed from the TRANSACTIONS table).

  2. If (code section, lot number) combination is NOT currently at the HISTORY_TABLE (or) the transaction code respective to item - batch number combination code is an operation then customs declaration date will be the date of the document (DOC_DT) that we receive from one of the 3 tables IN_TABLE_HEAD that contains the element of that particular lot.

• If the case 1 and case 2 fails, our customs declaration date will be the last date of document (DOC_DT) that we receive from one of the 3 tables IN_TABLE_HEAD containing that particular item and the BAT_NO in expected results will be that corresponding to this document, as appropriate, to another NULL.

• If the case 1 or case 2 is successful, the value of the last field (in the output expected, shown further below) BATCH_YN will be 'Y', because it fits the lot. Otherwise it will be 'n'.

• SQL query for the region of the tree

  Hello

  I was wondering if someone is able to help me work on a SQL query, to format the data in the table required in a part of the tree... I've never used a tree and I'm fighting to get the right data (if possible).

  The data in the table looks like this:

  

  I want to put it in a tree, using level 1 level6 with a final layout that would look like this:

  

  As you can see, the data are formatted in level6 down in the tree, but are filled in the table from level 1. Not all of the columns will be filled, so level2 for anyone 4 (France) is the equivalent of level in the tree like level6 to person 1 (Spain).

  This is Apex 4.2.5

  Oracle 11.2.0.3.0

  Sample data:

  CREATE TABLE employees
     ( employee VARCHAR2(100),
       level1 VARCHAR2(100),
       level2 VARCHAR2(100),
       level3 VARCHAR2(100),
       level4 VARCHAR2(100),
       level5 VARCHAR2(100),
       level6 VARCHAR2(100)   
     );
  
  INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person1','Team One','Recruitment','Human Resources','Fictituous Company','Murcia','Spain');
  INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person2','Team Four','Testing','IT','Big Corporate','Hanover','Germany');
  INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person3','Big Corporate','Hanover','Germany', null, null, null);
  INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person4','Brittany','France', null, null, null, null);
  INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person5','Team Three','Testing','IT','Big Corporate','Hanover','Germany');
  INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person6','Public Relations','Government Agency','Brittany','France', null, null);
  
  

  Added example given.

  Hello

  Apex-user wrote:

  Thanks Frank, this is a good example, I can work with that! Your assumptions are correct.

  A question I came, however, is that I have a data segment that comes across poorly formatted so to speak... where only the lower levels (1-2, etc.) have been filled from the bottom up.

  An example of this data would be:

  1. INSERT INTO employees (employee, level 1, 2, level3, level4, level5, level6) VALUES ('Person7', 'One Team', 'Test', null, null, null, null);

  As you can see that if you rerun the select, the test team is now duplicated, both at the level of the root in the tree as it should.

  You are not sure if the sql can be adjusted to account for this, or if it's too hard?

  It is obviously a question of data and I am trying to solve this separately (extracted data from another system out of my control).

  Thank you!

  Sorry, I'm confused.

  You say that my assumptions were correct.  What includes supported that "If test ' occurs under 'IT' in a row, then the extent of the 'Testing' occurs, it must be under"IT "?  Right after you say that assumptions are correct, you give an example where 'Testing' occurs under 'IT' to a single line, but it is not less 'IT' to another line and where is 'One Team' under 'Testing' in a line, but is 'One Team' under 'Recruitment' in another row.

  When a situation like this occurs, how you cope?  Whenever you have a problem, please post the exact results you want from the given sample data, and an explanation of how you get these results.  If you don't know about what would be the ideal results, or if you are flexible on the exact results, then at least give an example and explain your reasons.

  Maybe you want to change the got_parent of subquery like this:

  WITH unpivoted_data AS

  (

  SELECT *.

  Employees

  UNPIVOT (node_name

  FOR lvl (level1 AS 1

  level2 AS 2

  level3 AS 3

  level4 AS 4

  level5 AS 5

  level6 AS-6

  )

  )

  )

  got_parent AS

  (

  SELECT c.node_name

  MIN (p.node_name) AS a parent

  Of unpivoted_data c

  LEFT OUTER JOIN unpivoted_data p ON p.employee = c.employee

  AND p.lvl = c.lvl + 1

  GROUP BY c.node_name

  )

  SELECT LPAD (' ' ')

  2 * (LEVEL - 1)

  ) || Node_name AS entity

  OF got_parent

  START WITH parent IS NULL

  Parent = node_name PRIOR CONNECTION

  ;

  In this way, if 'Test' is current 'IT' in one line, but not under what in another line, whether under would consider the 'IT' request and not to be a root.  If 'One Team' sudden 'Testing' in a line, but under "Recruitment" in another line, it will be (arbitrarily) consider it under "recruitment".

• SQl query to find out time between the different lines of transactions

  (See both images from an attachment to get the clear picture of the data and understand the question correctly.)

  I have a set of data like this in one of my paintings. (This is a simple representation of the original data.)

  Reference table1.jpg

  ZTR0098 | ALLOW | 8. 21 JUN | 31 AUG |

  ZTR0098 | ADTAX | 45. 24 JUL | 31 AUG |

  each line has a type and a rasthaus id to it. ID belongs to other parent tables. the value of each type is given, and the validity of each value is followed by a field start_date and end_date.

  All values start from 1 - JUN and expires on 31 - AUG. Now my requirement is to obtain a report that gives three columns for three different types (ALLOW, ADTAX and MXTAX) with combination of unique values in the effective time interval. Let me put the result below.

  Reference table2.jpg

  Id         | ALLOW | ADTAX | MXTAX |  Start_date | End_date

  --------------------------------------------------------------------------------------------------------------------------------------------------

  ZTR0098 | 0 | 0 | 0 | 1 JUN | 2 JUN |

  ZTR0098 | 4. 44.00 | 0 | 3 JUN | 9 JUN |

  ZTR0098 | 4. 44.00 | 2. 10 JUN | 15 JUN |

  ZTR0098 | 5. 44.00 | 2. 16-JUNE | 17-JUNE |

  ZTR0098 | 5. 55,34 | 1. 18 JUN | 20 JUN |

  ZTR0098 | 8. 55,34 | 1. 21 JUN | 22 JUN |

  ZTR0098 | 8. 20.09. 1. 23 JUN | 25 JUN |

  ZTR0098 | 8. 20.09. 6. 26 JUN | 23 JUL |

  ZTR0098 | 8. 45. 6. 23 JUL | 31 AUG |

  As you can see there are no duplicate rows for a combination of (ALLOW, ADTAX and MXTAX) with their respective dates in force. resulting in the above table. the first step is to convert lines to the column which is pretty obvious to do that by grouping on start_date and end_date colum, but the real deal is the time interval during which the combination of the values (ALLOW, ADTAX, and MXTAX) has remained constant.

  I wrote under query using Group by.

  Select

  ID,

  NVL (max (decode (type, "ALLOW", value)), 0) as ALLOW

  NVL (max (decode (type, 'ADTAX', value)), 0) as ADTAX

  NVL (max (decode (type, 'MXTAX', value)), 0) as MXTAX

  Start_date,

  End_date

  from my_table

  Group of start_date, end_date, id

  start_date, end_date

  the results it gives are like this:

  Reference table3.jpg

  Id       | ALLOW | ADTAX | MXTAX |  Start_date | End_date

  ------------------------------------------------------------------------------------------------------------------------------------------------

  ZTR0098 | 0 | 0 | 0 | 1 JUN | 2 JUN |

  As you can see here, I'm recording a person of conversion from one program to the other, given that the query has been run since last month. The results I'm capture is for the month of February.

  I wanted the transition of the program 3-16 and 16-13, but not from 3 to 13. I need to eliminate the transition from 3 to 13. The reason why is this makes its appearance is due to the line

  AND to_date (tbl1.end_date, 'YYYYMMDD') < to_date (tbl2.start_date, 'YYYYMMDD').

  I use this because I want the result spans compared dynamically.

  I'm looking for change of this request (for example: we can have 10 entries on the table for a month, but have only 9 transitions listed in the final - either).

  Note: I would like to have a single query while as noted above, no procedure or query.

  Thanks in advance

  Hello

  Whenever you have a problem, please post a small example data (CREATE TABLE and only relevant columns, INSERT statements) of all the tables involved, so that people who want to help you can recreate the problem and test their ideas.

  Also post the exact results you want from this data, as well as an explanation of how you get these results from these data, with specific examples.

  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

  See the FAQ forum: Re: 2. How can I ask a question on the forums?

  You said that this problem was "creation of the pl/sql query", but you have probably not all PL/SQL; just SQL.

  2886750 wrote:

  ...

  AND to_date (tbl1.end_date, 'YYYYMMDD')< to_date="" (tbl2.start_date,="">

  Do not store information on dates in the string columns. Use the DATE columns. Then you won't need TO_DATE in conditions like this.

  You do a join to match each row in each previous row for the same person.  If I understand the problem, you don't want to compare with each previous line, you only want to compare with the last front row.  That sound like a job for the analytic LAG function.

• Clarification of the SQL query in 2 day + Guide APEX

  I worked through the Oracle Database Express Edition 2 day + Application Express Developer's Guide, and try to decipher the SQL query in Chapter 4 (building your app).

  The code is:

  SELECT d.DEPARTMENT_ID,

  d.DEPARTMENT_NAME,

  (select count (*) from oehr_employees where department_id = d.department_id)

  "Number of employees", he said.

  substr (e.first_name, 1, 1) |'. ' || Select 'Name Manager',

  c.COUNTRY_NAME 'place '.

  OEHR_DEPARTMENTS d,

  E OEHR_EMPLOYEES

  OEHR_LOCATIONS l,

  C OEHR_COUNTRIES

  WHERE d.LOCATION_ID = l.LOCATION_ID

  AND l.COUNTRY_ID = c.COUNTRY_ID

  AND e.department_id = d.DEPARTMENT_ID

  AND d.manager_id = e.employee_id

  AND instr (superior (d.department_name), superior (nvl (:P2_REPORT_SEARCH,d.department_name))) > 0)

  I don't know exactly what is happening in the last line. I think I understand what the different functions but I'm not clear on the use of the: P2_REPORT_SEARCH string.

  What does this string? This code simply checking that d.department_name isn't NA?

  I have SQL experience but am not very familiar with the Oracle PL/SQL implementation. Can someone please give me a brief breakdown that check is doing in the context of the overall query? The application seems to work even if the conditional statement is not included.

  Thank you.

  Thanks for the reply. I apologize if the information I added was incomplete. The code came from the day 2 + Application Express (version 4.2) Developer Guide.

  In the section 'your own Application of 4 Buuilding' https://docs.oracle.com/cd/E37097_01/doc.42/e35122/build_app.htm#TDPAX04000 , they describe the creation of a report

  page that includes the "manager_id" and 'location_id '. The SQL query, I pasted above extracted from the data in other tables to substitute the real 'name of the Manager' and 'rent '.

  for the corresponding ID values. It makes sense, and the part of the SQL query that explicitly doing this makes sense.

  However, given that the document is a guide for the development of the APEX, I guess the command:

  AND instr (upper (d.department_name), upper (nvl (:P2_REPORT_SEARCH,d.department_name))) > 0

  done something valuable, and I do not recognize what is exactly the value.

  From a practical point of view why would I need to include this conditional statement?  Which only added to the application?

  Looking at the guide in question, it is clear that the

  AND instr(upper(d.department_name),upper(nvl(:P2_REPORT_SEARCH,d.department_name)))>0
  

  the line is completely unnecessary in the context of this tutorial, and it can be removed. The search in the tutorial app page is implemented by using a report filter interactive rather than a P2_REPORT_SEARCH element, which does not seem to exist at all. (It's a quirk of the APEX that bind variable references to non-existent items are replaced with NULL silently rather than exceptions). I thought that perhaps it would be legacy code a version of the tutorial prior to the introduction of interactive reports at the APEX 3.1, but I can't find explicit instructions to create such an element of filter in the 3.0 tutorial. I guess it must have been automatically generated by the application wizard when you create a standard report page.

  If you do not want to see the effect he would have (as described in the post above), leave it in the source report, add a text element of P2_REPORT_SEARCH, and a button "submit" on page 2 and experimenting to find different values of the element and clicking on the submit button...

• What is the best way to optimize a SQL query: call a function or doing a join?

  Hi, I want to know what is the best way to optimize a SQL query, call a function inside the SELECT statement, or make a simple join?

  It depends on.  Could be a.  Could be the other.  Could be no difference.  You would need to compare with your tables in your environment with your settings.

  If you put a gun to my head, I was given no other information and required that I answered the question, I would tend to wait that the join would be more effective.  In general, if you can do something in pure SQL, it will be more effective than if you call PL/SQL.

• Dynamic PL SQL query

  Hello

  I want to run and store the results of a dynamic sql query in a strored procedure.

  I get the following variables of the user running: v_column_names, v_table_name, v_col, v_value

  The query will be like:

  v_query: = 'SELECT'. v_column_names | ' A ' | v_table_name | ' WHERE ' | v_col |' = ' | v_value;

  for example v_column_names: = 'ACCOUNT_NUM, SYSTEM_ID, ENTITY_ID ';

  v_table_name: = 'ACCOUNT '.

  v_col: = 'COUNTRY_CODE ';

  v_value: = "USA";

  Here is what I tried

  DECLARE

  v_column_names VARCHAR (200): = 'ENTITY_ID, SYSTEM_ID, ACCOUNT_NUM;

  v_table_name VARCHAR (200): = 'ACCOUNT '.

  v_col VARCHAR (200): = 'COUNTRY_CODE ';

  v_value VARCHAR (200): = "'USA"';

  TYPE column_record () IS RENDERING

  VARCHAR2 (200) C1: = null;

  C2 VARCHAR2 (200): = null;

  C3 VARCHAR2 (200): = null

  );

  TYPE st_table IS TABLE OF column_record INDEX DIRECTORY.

  pk_table st_table;

  NUMBER of v1: = 1;

  BEGIN

  v_select: = 'SELECT'. v_column_names | ' A ' | v_table_name | ' WHERE ' | v_col |' = ' | v_value;

  EXECUTE IMMEDIATE v_select COLLECT LOOSE pk_table.

  I'm IN 1.pk_table.count LOOP

  DBMS_OUTPUT. Put_line (pk_table (v1). (C1);

  DBMS_OUTPUT. Put_line (pk_table (v1). (C2);

  DBMS_OUTPUT. Put_line (pk_table (v1). (C3);

  v1: = v1 + 1;

  END LOOP;

  END;

  The number of column names in v_column_names is dynamic, so I need a way to store the results and then manipulate them.

  I look forward to your reply.

  EDIT: The real question:

  1. in the settings I have pass the table name and the value of the primary key of the row I want to delete.

  2. He then checks if this line is referenced anywhere, removes the reference, and then deletes the current line. This can go, until all the rows that are referenced are removed.

  The above code, I have provided a small part of the largest of stored procedure.

  Thank you all, I found the tips very helpful. I found a solution to my problem:

  Oracle - how to build queries DELETE in PL/SQL, based on the tables of the FK relations? -Stack overflow

  It generates all removal requests to remove a specific line.  Not what I wanted, but this does not solve my problem.

  The reason why is that I discovered that we do not use the ON DELETE CASCADE that we don't remove a record accidentally, I know we have an option to restore, but it is just in case something goes wrong.

• Efficient SQL query

  Hello
  I need to write an efficient query because the query about 4 checks to be made on the lines before you return one row. Here's a sample script in query to create the table:
  
  CREATE TABLE "myschema". "" Complaint. "
  (
  "Compalint_ID" NUMBER (20.0).
  "ReplyTime' NUMBER,-it would be in a few minutes
  "CREATION_TIME' TIMESTAMP (6).

  I want to write an efficient pl/sql-sql query with the least time to return a row based on four following priorities/controls in the order specified below:
  
  1 return any line that contains a TYPE = 11
  
  2. If no line found for 1 check then
  calculate a difference in time for all of the lines as: time_difference (CREATION_TIME - ReplyTime)
  and back to the line that has more big differene in - ve (it is the line which expired first)
  
  3. If now the found line to check then the 2
  rank next where STATUS = 22
  
  4. If no line found to check then the 3
  calculate a difference in time for all of the lines as: time_difference (CREATION_TIME - ReplyTime)
  and back to the line that has a smaller difference in + ve (it is the line that will expire then)
  
  
  Kindly help me in this task.
  
  Thank you.

  @1
  I have the suggestion of Daniel while avoiding reserved words and now I see an error in copy/paste complaint_ casetypestatus when 22 then 22 end check3

  @2
  Bilal already you made in the right direction, anyway: as many others pointed out that you can not combine functions of the group the way which you intend to so using functions analytical has been the only issue keeping all lines and the calculation of the required amounts and charges in the query internal to combine in the outer query.
  complaint_type case when 11 11 then end keeps only the 11 complaint_type all other complaint_type null values
  Max (case complaint_type when 11 11 then complete) on check1_max (order by NULL rows between unbounded preceding and following unbounded), calculates the global maximum of the expression (in all the rows of the table)

  @3
  I used systimestamp - (creation_time + reply_time / 60/24) just to produce a positive or negative number as your time_difference (CREATION_TIME - ReplyTime) somehow confused me (timestamp less number gives timestamp if positive or negative is not an appropriate question) so the above expression as used so far is something you know how (re) set. Other required clarification/explanation at this stage.

  @4
  If the fraction of the second precision is not necessary using the date data type should be sufficient (environmental CAR you cannot rule out dealing with the events with the same timestamp) and what is the thrown error using systimestamp

  Concerning
