• Dynamic recovery for the dynamic sql query

  Hi all
  
  I want to create a query dynamically and to fetch it in a dynamic cursor record... The structure of the record should be the same as that of the query...
  Can you suggest any method to do this.
  
  for example
  
  OPEN < dynamic news > TO < dynamic stmt >;
  LOOP
  FETCH < dynamic news > < DYNAMIC rec >;
  ---
  END LOOP;
  CLOSE < dynamic news >;
  
  How to declare the rec here dynamic? I wouldn't have the columns in the query in advance either.
  
  Thank you

  Is not possible. What you describe is called four dynamic sql type. For this type of synamic SQL, you use the DBMS_SQL package.

• A difficult dynamic SQL query problem

  Hi all
  
  I have a very interesting problem to work:
  
  We have this special table defined as follows:
  
  CREATE TABLE sales_data)
  sales_id NUMBER,
  NUMBER of sales_m01
  NUMBER of sales_m02
  NUMBER of sales_m03
  NUMBER of sales_m04
  NUMBER of sales_m05
  NUMBER of sales_m06
  NUMBER of sales_m07
  NUMBER of sales_m08
  NUMBER of sales_m09
  NUMBER of sales_m10
  NUMBER of sales_m11
  NUMBER of sales_m12
  sales_prior_yr NUMBER);
  /
  
  Columns ' sales_m01... sales_m12' represents aggregated monthly sales, what "sales_m01" is translated by "sales for the month of January, January is the first month,"sales_m02"in sales for the month of February and so on.»
  
  The problem I encounter is that we have a project that requires that a parameter is passed to a stored procedure that represents the number of months which is then used to create a SQL query with aggregations of next mandatory field, which depends on the parameter passed:
  
  Example 1: entry of parameter: 4
  Should be built dynamically to SQL query:
  
  SELECT
  Sum (sales_m04) as CURRENT_SALES,
  Sum (sales_m01 + sales_m02 + sales_m03 + sales_m04) SALES_YTD
  Of
  sales_data
  WHERE
  sales_id = '0599768';
  
  Example 2: input parameter: 8
  Should be built dynamically to SQL query:
  
  SELECT
  Sum (sales_m08) as CURRENT_SALES,
  SUM (sales_m01 + sales_m02 + sales_m03 + sales_m04 +)
  sales_m05 + sales_m06 + sales_m07 + sales_m08) SALES_YTD
  Of
  sales_data
  WHERE
  sales_id = '0599768';
  
  
  So in a sense, the contents of SUM(sales_m01...n) would vary according to the parameter, which must be a number between 1... 12 what is a month, which in turn corresponds to a range of real field on the table itself. The resulting dynamic query should include only those columns/fields in the table that is within the range given by the input parameter and does not account for all the other columns/fields.
  
  Any solution is greatly appreciated.
  
  Thank you.

  SQL> declare
    cols long;
    param integer := 6;
    sales_id integer := 0599768;
  begin
    for i in 1..param loop
      cols := cols || 'sales_m' || to_char(i, 'fm00') || '+';
    end loop;
  
    dbms_output.put_line('select sum(sales_m'||to_char(param,'fm00')||') current_sales, sum(' || rtrim(cols,'+') || ') sales_ytd from sales_data WHERE sales_id = :1');
  end;
  /
  select sum(sales_m06) current_sales, sum(sales_m01+sales_m02+sales_m03+sales_m04+sales_m05+sales_m06) sales_ytd from sales_data WHERE sales_id = :1
  PL/SQL procedure successfully completed.
  

  Now it should be obvious:
  Instead of dbms_output OPEN a refcursor:

  SQL> declare
    cols long;
    param integer := 6;
    sales_id integer := 0599768;
    cur sys_refcursor;
  begin
    for i in 1..param loop
      cols := cols || 'sales_m' || to_char(i, 'fm00') || ',';
    end loop;
  
    open cur for 'select sum(sales_m'||to_char(param,'fm00')||') current_sales, sum(' || rtrim(cols,',') || ') sales_ytd from sales_data WHERE sales_id = :1' using sales_id;
    .....
  end;

• Dynamic SQL query in the DB adapter

  Hello
  I want to use the following custom SQL query in the DB adapter:
  
  SELECT EMP_ID, EMP_NAME, EMP_LOCATION FROM EMP WHERE EMP_ID IN (#iNPUT_PARAMETER)
  
  the problem I'm facing is that I don't know at the time of the development that EMP_ID how much will be passed to the process so that I can not use the input parameter specific number. I cannot use it IN the query within which statement I concatenate all the EMP_ID separated by comma and passed under INPUT_PARAMETER, but when running, he read the full concatenated string as a single string rather than identify them as a list of different: with comma separation. could someone help me in this case
  
  Thank you
  Sunil

  Use the following query with two parameters. Build the string with delimiter when running and pass this string and delimiter to query... (in this example, the input value would be the same for both Delimiter1 and Delimiter2.)

  Select * from EMP WHERE deptno IN (SELECT SUBSTR (STRING_TO_TOKENIZE, DECODE (LEVEL, 1, 1, INSTR (STRING_TO_TOKENIZE, SEPARATOR, 1, LEVEL-1) + 1), INSTR (STRING_TO_TOKENIZE, SEPARATOR, 1, LEVEL)-DECODE (LEVEL, 1, 1, INSTR (STRING_TO_TOKENIZE, SEPARATOR, 1, LEVEL-1) + 1)) FROM (SELECT #StringToTokenizer | #Delimiter1 AS STRING_TO_TOKENIZE, #Delimiter2 AS DELIMITER FROM DUAL) CONNECT BY INSTR (STRING_TO_TOKENIZE SEPARATOR) ((, 1, LEVEL) > 0)

• Dynamic SQL query to get the unique value of list in a column

  I have two tables: tblWorkers and tblSkills. tblWorkers has a column, skills, which is populated by a field of multiple-checkbox with one or more skill_IDs of tblSkills, so each tblWorkers.Skills consists of a list of one or more comma-delimited values. For any Skill_ID, I need to generate a list of all workers with the appropriate skills, so I tried to do something in the direction of SELECT WorkerName FROM tblWorkers WHERE IN of skills (skills, #FORM. Skill_ID #)... or WHERE skills (ListFind (skills, #FORM. Skill_ID #))... etc.? My results (once I have had data type mismatches of the road) return all workers, not just those with the desired skills. There must be an easy way to do... How people with a little more experience CF/SQL I do this?

  > each tblWorkers.Skills consists of a list of one or more comma-delimited values

  This is your problem. You store a list of values that you want to access power/query separately in a single column. You will have to burst in a separate table.
  TblWorkers

  TblSkills

  TblWorkerSkills
  mapping table of many workers with skills.

  If you do not change your data model now, you will constantly be butting your head against that.

• 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.

  Probably not.  Dynamic SQL is generally less effective than static SQL, as well as being more difficult to code, debug and maintain.

  Is there a reason why you think that the dynamic SQL would be preferable in this case?  If so, what is it?

• DA on updatable report items Sql query using the class

  Request Express 4.2.5.00.08

  10-11 g Oracle

  I have a page, so it has a link/button when he clicks then modal region will appear. Modal region has a as a table (Type SQL Query (updateable report)). All work very well so far.

  
  

  However, I've now added some complex things.

  for example. My region is based on the query of SQL Type (editable report).

  SELECT id, name of family, Traghetti, area, d_date, start_time, End_time, displacement, role of table where id =: P10_ID;

  I can also add a new line of course.

  My problem is, (point) Shift display based on the value of Start_Time point) and so I made sure the class for two items.

  for example, Start_Time (' class = "st_tm" ') and Maj ('class to = "Shift_time" '). Start_Time is based on (LOV) and shift is off the point in the sql query, but change the Start_Time.

  And now, I created the DA.

  jQuery Selector: .st_tm

  Condition: No.

  1. action: set value

  Set type: Expression Javascript

  The JavaScript Expression: $(this.triggeringElement) .val ();

  The element affected: P10_X1 (it is a hidden item)

  2. action: Plsql Code

  Code: start to null; end;

  Page items to submit: P10_X1

  3. action: Plsql Code

  Code: start

  If: P10_X1 between '03' AND '11' then

  : P10_X1: = 'EARLIES ';

  elsif: P10_X1 then '12' and '18'

  : P10_X1: = 'LATES ';

  on the other

  : P10_X1: = 'NIGHTS';

  end if;

  end;

  Page items to submit: P10_X1

  NOW another DA

  Event: change

  Article (s) P10_X1

  Condition (in list)

  value (HASTY, LATES, NIGHTS)

  Action:

  Set type: Expression Javascript

  The JavaScript Expression: $(this.triggeringElement) .val ();

  Affected item:

  Selection type: jQuery Selector

  jQuery Selector:. Shift_time

  Well, I look forward all the above work well, but I'm having a problem.

  If I have more than 1 lines on a modal region and if I change the Start_Time value for a row then MAJ (point) is changing but he effect on all lines.

  I want, if I make the changes on the line line # 2 while only 2 # MAJ (point) must be not performed any other lines?

  Help, please!

  Kind regards

  RI

  I found the solution me thank you.

  I removed all the DA mentioned above and created a new.

  1. event: change

  Selection type: jQuery Selector

  jQuery Selector: .st_tm

  Condition: No.

  Scope of the event: dynamic and light on page load.

  Action (Javascript code)

  ROW_ID = $(this.triggeringElement).attr('id').substr (4);

  If ($(this.triggeringElement). val() > = 03 &. val() $(this.triggeringElement))<= 11)="">

  .Val ('EARLIES') $(«#f11_» + row_id);

  }

  ElseIf ($(this.triggeringElement). > 11 val() & $(this.triggeringElement). val())<= 18)="">

  .Val ('LATES') $(«#f11_» + row_id);

  }

  ElseIf (. val() > $19 (this.triggeringElement)) {}

  .Val ('NIGHTS') $(«#f11_» + row_id);

  }

  also created another DA because I have a disabled report items.

  Event: before the page is sent.

  $('_:_disabled').removeAttr ("disabled");

  and finally created manual process of DML for tabular and everything works fine. (Insert, Update, and delete).

  Kind regards.

  Hi all

  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.

  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.

  Hey guys,.

  I can print my classic report in PDF or CSV format.

  I need is like this cause my 'where' clause type is dynamic.

• How to extract the names of columns in dynamic SQL

  Hi all

  Is it possible to extract all the names of columns in a dynamic query?

  In my case according to the user selections that my query will get changed (number of the column, column name and tables that everything can vary).

  So now, is it possible to retrieve all the column names of the dynamic query generated?

  I am using Oracle 11g (11.2.0.4)

  Thank you
