• How to find the name of a column in a table

  Hi all
  
  I have a Table that contains approximately 100 columns.
  
  
  I need to find the column name, to find in specific columns containing data like 'abc '.
  
  Ex: I have a table like temp_table_name
  the columns are col1, col2, col3, col4, col5, col6, col7, col8,.... col99
  I'm looking for with data specific like 'abc '.
  
  Need to find the name of the table column that contains data of 'abc '.
  
  Please suggest me. How to find in a single query... :-)
  
  Actually I'm looking through a column of the table as below
  Select count (*) in the temp_table_name where col1 = 'abc '.
  
  FOR I IN 1.20 LOOP
  ln_num_of_rows: = 0;
  lv_column_name_search: = "col" | I have;
  
  lv_sql: = ' select count (*) in the temp_table_name where ' | lv_column_name_search | "= abc";
  
  EXECUTE IMMEDIATE lv_sql INTO ln_num_of_rows;
  
  IF ln_num_of_rows > 0
  -column found in lv_column_name_search
  EXIT;
  END IF;
  END LOOP;
  
  But I'm gettig performance problem.
  
  How can I do this in any other alternative way? could you suggest any way possible as soon as POSSIBLE.

  It's probably never going to be effective - realistic, you have to scan completes the picture.

  You could probably improve a little things by doing something like

  SELECT DISTINCT column_name
    FROM (
      SELECT (CASE WHEN col1 = 'abc' THEN 'col1'
                  WHEN col2 = 'abc' THEN 'col2'
                  WHEN col3 = 'abc' THEN 'col3'
                  ...
                  WHEN col20 = 'abc' THEN 'col20'
                  ELSE NULL
                  END) column_name
        FROM table_name
      WHERE col1 = 'abc'
          OR col2 = 'abc'
          ...
          OR col20 = 'abc'
    )
  

  but it's never going to be incredibly fast.

• Correspondence of the columns from one table to another

  I have a database column that contains the name of a person. I have another table that has a column that contains the names separated by a comma.

  I want to match records where all records of two columns have a corresponding name. I tried this:

  < cfquery name = "MyQuery" datasource = "myds" >

  SELECT *.

  OF TBL_A

  WHERE TBL_A.customername IN (#DifferentQuery.ListOfNames #)

  < / cfquery >

  Everything that I try results in only get a recording. Basically, I want to get all records from a table where one of its columns contains the name of a column in another table.

  It's a many-to-many relationship. That is to say an editorial can be linked to many ads, and vice versa.  He is best represented with three tables. Such as:

  Table: [Editorial] column: [EditorialID (PK), EditorialText,...]

  Table: Columns of the [advertiser]: [AdvertiserID (PK), AdvertiserName]

  Table:   [Editorial_Advertisers] columns: [EditorialID, AdvertiserID]

  The name of the advertiser throw himself into a column...

  my client can decide which ads get related to which editorials

  The third table stores the relationship between ads and editorials.  So instead of storing a list of advertisers, you need to insert record for each EditorialID + AdvertiserID combination. You can then use joins to retrieve all the advertisements for EditorialID 123.

  SELECT  a.AdvertiserName
  FROM     Editorial_Advertiser ea INNER JOIN Advertiser a ON ea.AdvertiserID = a.AdvertiserID
  WHERE   ea.EditorialID = 123

  I added a new column with an alias "get data". This new column will display "NO" is the entire column is zero and 'YES' if there is even a value not null in the column. But caution is that statistics table must be updated to get the correct results.

  Thus, it may be useful to gather current statistics before executing the query.

  Exec dbms_stats.gather_schema_stats or even dbms_stats.gather_database_stats.

  Any help please

  If you are running this as a different user than the ADMIN you will also need to add the schema name.

  EXECUTE IMMEDIATE 'SELECT COUNT(*) FROM ' ||t1.owner||'.'||t1.table_name|| ' WHERE ' ||t1.column_name || ' = :1' INTO cnt USING v_data;
  

  The error could be any strange names of tables or columns. For example, if they contain spaces in the name.
  If you have names, then all identifieres must be placed in "."

  + untested example +.
  {code}
  RUN IMMEDIATELY "SELECT COUNT (*) FROM" ' | "" T1. Owner: ' ». » ' || T1.table_name | " » OÙ « ' || T1.column_name | "" =: 1' IN cnt USING v_data;

  Table_name group

  order of table_name;
