• SELECT query

  Hello

  First of all, I had two tables. The first PARAMETER called that inculdes three columns parameter_id (number), the parameter_desc (varchar2 (20) and (number) parameter_value.) The parameter_id is a PK. The INSERT statement might like this:

  Enter the parameter (parameter_id, parameter_desc, parameter_value) values (1, 'TEST1', 233);

  Enter the parameter (parameter_id, parameter_desc, parameter_value) values (2, 'TEST2', 456);

  Insert in the parameter (parameter_id, parameter_desc, parameter_value) values(3,'TEST3',678);

  And a second table, called TOPO_PARAM, which includes three columns (number) topo_id, parameter_id (number) and topo_param_value (varchar2 (10).) The PK is on topo_id and parameter_id. The insert for this one is

  insert into topo_param (topo_id, parameter_id, topo_param_value) values (349.1, 'FALSE');

  insert into topo_param (topo_id, parameter_id, topo_param_value) values (568,2, 'TRUE');

  I want a select query that links the two tables and returns this:

  If topo_id = 349

  I wish to have this:

  parameter_id parameter_value topo_param_value                   

  1                                   233                                   'FALSE'

  2                                   456                                    NULL

  3                                   678                                    NULL

  If topo_id = 568,

  parameter_id parameter_value topo_param_value                

  1                                   233                              NULL

  2                                   456                              'TRUE'

  3                                   678                              NULL

  And if topo_id = 500,

  parameter_id parameter_value topo_param_value              

  1                                   233                         NULL

  2                                   456                         NULL

  3                                   678                         NULL

  Thanks for your response!

• as with the select query

  Hello

  I have a query something like...

  Select...

  ....

  where

  b.ProdName as 'GEAR of the TREE %' or b.prodname like '% FRONT GEAR %' or b.prodname like '% BREAK 4 %k '.

  and

  b.ProdName as

  (select the name of the society of companyms

  where < some comdition >

  )

  order of 3.6

  I have blocked in:

  b.ProdName as

  (select the name of the society of companyms

  where < some comdition >

  )

  How to give a select query with like operator.

  In above query I want to b.prodname as above and the name of the company for which I give condition.  Company names are stored in another table and I want to select and use them with like operator.

  Thank you.

  Hello

  It is not clear what you want to do.

  One possibility is an EXISTS subquery, like this:

  ...

  WHERE (b.prodname LIKE "% of the CYCLE of the TREE" - begins with this text

  OR b.prodname LIKE '% FRONT GEAR %' - contains this text

  OR b.prodname LIKE '% BREAK 4 %k' - contains this text

  )

  AND THERE ARE)

  SELECT 1

  OF companynms

  WHERE--a condition

  AND b.prodname AS business

  )

  I hope that answers your question.

  Hello

  This is called String aggregation . See
  http://www.Oracle-base.com/articles/10G/StringAggregationTechniques.php
  many ways to do it.

  Which way is best for you? It depends on your version of Oracle and your specific needs.
  For example, if you use Oracle 11.2, and you want the secondary channels ordered:

  SELECT    projid
  ,       LISTAGG (building_num, ';') WITHIN GROUP (ORDER BY building_num)     AS building_nums
  FROM       table_x
  GROUP BY  projid
  ;
  

• SELECT query problem

  Hi all
  
  Need select records less where Rownum < = 100, a table in which the records are classified by a field in a query, but after stopped in the ordering of rownum gets changes.
  

   
  with t as (select 1 a,'d' b from dual 
  union select 8 a,'t' b from dual 
  union select 3 a,'u' b from dual 
  union select 7 a,'k' b from dual ) 
  select t.*,rownum from t order by 2 ;
  
  
  A B ROWNUM 
  1 d 1 
  7 k 3 
  8 t 4 
  3 u 2 

  Now I want to select records where ronum < = 2 as below, this can be done by changing only in where clause and do not touch the query select, as can do a nested query I but need to do it by changing only in where clause.
  

   
  A B ROWNUM 
  1 d 1 
  7 k 3 

  Thanks in advance
  
  Thanks and greetings

  No, there is no way to get these results by changing only the WHERE clause. As it is, you have no column or expression in the main query that indicates how the lines are classified according to b, which is exactly what to test in the WHERE clause. (Remember, ROWNUM is assigned before ORDER BY is done in the same auxiliary request). You must add a using ROWNUM or ROW_NUMBER analytic function. either way requires some preparation to be done in a subquery.

  For example, the following query has an ORDER BY clause, added to the request slot, so that ROWNUM in the main query will be more arbitrary:

  with t as (select 1 a,'d' b from dual
  union select 8 a,'t' b from dual
  union select 3 a,'u' b from dual
  union select 7 a,'k' b from dual
  ORDER BY  b                              -- Added
  )
  SELECT    t.*
  ,       ROWNUM
  FROM        t
  WHERE       ROWNUM     <= 2     -- Added
  ORDER BY  b
  ;
  

  Output:

  `        A B     ROWNUM
  ---------- - ----------
           1 d          1
           7 k          2
  

  It is no coincidence that the numbers in the column ROWNUM are 1 and 2. If you want really to arbitrary numbers (such as 1 and 3), you will need an another subquery.

  DBA dear friends,

  Thank you

  Hi, Mike,.

  If there is something else in the more SELECT clause *, then * must be qualified with a table name or alias.

  For example:

  SELECT Mytable. *, col1, col2

  FROM MyTable;

• place a select query calculation in a different column in the same table

  How can I put my calculation result in a column named within the same table?

  I have a table called: dgpercentagedatachart

  I use the columns of this dgpercentagedatachart: totalcecrating divided by lowestfeederrating times 100 to get the percentage

  In the query, I gave the result the Alias of the cal

  What I want is to put this result in my application or my calculation (in percentage) in my column "percent" on my table of dgpercentagedatachart vacuum.

  How can I configure this syntax?

  This is the select query, I came with:

  Select dgpercentagedatachart.totalcecrating, dgpercentagedatachart.lowestfeederrating,.

  100.00*dgpercentagedatachart.totalcecrating/dgpercentagedatachart.lowestfeederrating as cal

  To change an existing column in a table, you can use the UPDATE or MERGE, instructions like this:

  UPDATE dgpercentagedatachart

  Percentage of VALUE = 100,00 * totalcecrating

  / lowestfeederrating

  ;

  Noramlly, tables is not redundant columns like this.  If percent can always be calculated from other columns, then it is probably better to calculate at run time and store it in the database, where you will have to be updated each time the columns it depends on change.  You can use a view to avoid having to encode them the calculation.

  If you really don't want a column that can be calculated in the same lines other columns, then use a virtual column (if you use Oracle 11 or higher).

  I hope that answers your question.

  If this isn't the case, please post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also publish outcomes from these data.

  If you ask on a DML statement, such as UPDATE, the sample data will be the content of the or the tables before the DML, and the results will be the State of the or the tables changed when it's all over.

  Explain, using specific examples, how you get these results from these data.

  NOTE: the query worked well for a while, no errors, then all suddenly it became much accentsr and then I started to get the error message above.

  Kind regards

  Hello

  ORA-27072: IO file error

  Linux-x86_64 error: 28: no space is available on the device

  Looks like a system or OS, no SQL or PL/SQL problem problem.  I think you will answer sooner if you check this issue as 'Response' and start a new question in the forum of "General Question":

  https://forums.Oracle.com/community/Developer/English/oracle_database/general_questions/content

  My guess is that Oracle tries to allocate space in the tablespace temp, but cannot because the disk is full.  If you have a full disk, then create the space to this topic.

  I see nothing wrong with your code; Certainly, nothing which would cause an error like that.  The fact that the query has worked well for some time confirms that there is noting wrong with the request itself; It is just triggering a mistake elsewhere.

• Formatting of the Select query

  The following select query returns the data in green.  How do I format to return the path that it is formatted in red?

  Basically, if FIELD1 is "Customer A" and FIELD2 is "Gas" then I back to 'New customer' Field1 and Field2 'gas '.  If 'Customer E' FIELD1 and FIELD2 is 'Total' then it should return 'E rejection' in Field1 and 'Prod_Discharge' in the Field2.

  Please let me know if my question is not sensible or need to be clarified.

  SELECT

  DECODE (Field1, 'Nine', ' A', 'Old', 'E', 'Term', 'F', Field1)

  DECODE (Field2, 'Prod', 'Gas', Field2)

  Customers

  FIELD1 FIELD2

  Customer A gas

  Customer has oil

  Total customers E

  Customer F Total

  Need to format as follows:

  Field1 Field2       

  New gas customer          

  New customer oil      

  E Prod_Discharged releases          

  F Prod_Discharged releases

  Try this:

  SELECT CustomerID

  , CASE WHEN field1 = 'Customer A' THEN 'new customer '.

  WHEN field1 = 'Customer E' AND field2 = 'Total' THEN 'E releases '.

  WHEN field1 = ' customer F ' AND field2 = 'Total' THEN 'F performs ".

  Of ANOTHER Field1

  FIELD1 AS END

  , CASE WHEN Field1 IN ('E of customer', ' customer F ') AND field2 = 'Total' THEN 'Prod_Discharged '.

  Of OTHER Field2

  END AS FIELD2

  Status

  Customers

• How to run a Select query stored in a Variable

  Hello
  
  I have a following requirement:
  
  Select a query result on Var1, result of another request selection in Var2,
  If Va2 = "value11" or Var2 = "Value2" then Var1 = "select query. Now how can I run this SQL at the end of the Pl/SQL query?
  
  so I write request for the same thing:
  
  DECLARE
  qry nvarchar2 (500);
  result nvarchar2 (500);
  
  BEGIN
  
  Select "choose TEXTVAL as 'CHARGER' FROM TABLE1 WHERE LOC =" [ParameterValue] "and KEYNAME =" < < REPLACE > > "' double INTO qry ;"
  
  SELECT CASE County WHEN (RW." CountofBATCH') > 1 then "mixture."
  WHEN count (RW." CountofMAT') = 0 then 'None '.
  ANOTHER 'other '.
  END
  AS a result
  TABLENAME2 TT, XMLTable ('/ sets of lines/lines/lines ' PASSAGE TT.) XMLCOL
  COLUMNS
  "CountofBATCH" PATH "/ row [CLABS > 0] / LOADED ',"
  "CountofMAT" PATH "/ row [MATNR = '[parameter value]'] / MAST '"
  ) AS RW
  
  where
  TT.PL = '[parameter value]' and
  TT. TANK = "[value settings]";
  
  IF result = 'Mixture' result GOLD = 'None' THEN
  qry: replace = (qry, "< < REPLACE > >", result);
  on the other
  qry: = 'nothing. '
  END IF;
  
  Thus the qry variable will have select statement. Now how can I use this to get the select result of this statement in the same query qry?

  You can use execute immediately if the output of the query is in the same query.

  It's very simple.
  a query string signle and then go like this

  declare
  qry VARCHAR2 (255);
  result varcharf2 (2500);
  number of vempid: = 1;

  Start
  qry: =' select empname emp where empid =: empid ";

  run immediately qry in the result using vempid;
  -now the result of data is as a result
  end;

• Sinlge select query in the diff for the same table (same Structure) diagrams

  Scenario:
  
  Table XYZ is created in detail a.
  After a year, the old data of the previous year could be moved to another schema. However in the other schema of the same table name would be used.
  
  For example
  
  A schema contains XYZ table with data from the year 2012
  Schema B contains XYZ table with data for the year 2011
  Table XYZ in the two schemas have an identical structure.
  
  So we can draw a single select query to read the data from the tables in an effective way.
  For example select * from XYZ so including date between October 15, 2011 to March 15, 2012.
  However, the data resides in 2 different schema altogether.
  
  
  Creating a view is an option.
  But my problem, there are ORM (Hibernate or Eclipse Top Link) layer between the application and the database.
  If the queries would be constituted by the ORM layer and are not generated by hand.
  So I can't use the view.
  So is there any option that would allow me to use only query on different scheme?

  Why not make the ORM as below?

  SELECT * FROM VIEW_BOTH;
  -VIEW_BOTH is a real VIEW of Oracle

• Please suggest a select query / under query with using any routines or

  source table: three columns ORIGIN, DESTINATION, MILES
  
  Origin Destination Miles

  Why? If the most effective way to achieve the desired results is to use a function, why would you not use it?

  Here's a way, without all the features:

  SELECT     a.*
  FROM           source_table  a
  LEFT OUTER JOIN      source_table  b  ON   a.origin          = b.destination
                                        AND  a.destination       = b.origin
                        AND  a.miles          = b.miles
  WHERE   b.origin  > a.origin    -- Not b.origin > b.origin
  OR     b.origin  IS NULL
  ;
  

  If you would care to post CREATE TABLE and INSERT statements for your sample data, and then I could test this.

• Can get us data back from a stored procedure in a select query?

  Hello
  Suppose I have a function GetSum(x,y) that returns the sum of two numbers x and y. We can call this function from a function sql like this:

  select GetSum(4,5) SUM from dual;

  But it's possible thanks to a stored procedure? for example, can I call a stored procedure from a select query, as I did above code?
