Question

I am having trouble with a select statement and not sure what I am doing wrong. This is the structure of the source table:

Source Schema DATA1

Source Table FOLDERS

Source Columns FOLDERID, USERID

Destination Schema DATA1

Destination Table FOLDER_USER

Destination Columns FOLDER_ID, USER_ID

And here is the query ( I need to change the folder ID as it is being pulled out of the first query hence the case):

DECLARE
BEGIN
   FOR FOLDER_ROW IN (SELECT FOLDERID = CASE 
                                WHEN FOLDERID = '10' THEN '1'
                                WHEN FOLDERID = '565' THEN '2'
                                WHEN FOLDERID = '11' THEN '3'
                                WHEN FOLDERID = '81' THEN '4'
                                ELSE '0'
                            END, USERID FROM DATA1.FOLDERS WHERE UPPER(OWNER) = 'ADMIN')
      LOOP                       
          INSERT INTO DATA1.FOLDER_USER (FOLDER_ID, CORP_ID) VALUES (FOLDER_ROW.FOLDERID, FOLDER_ROW.CORPID);
     END LOOP;
    COMMIT;
END;

I get the following error when I execute and I’m stuck as to why I am getting it. I know it has something to do with the case inside the select:

ORA-06550: line 3, column 39:
PL/SQL: ORA-00923: FROM keyword not found where expected
ORA-06550: line 3, column 22:
PL/SQL: SQL Statement ignored

Answer 1

SELECT FOLDERID = CASE is wrong. It should be SELECT CASE ….. END As FOLDERID
