Hi All,

I have i table column with values like ('XYZ','ABC','OPQ','PQR')which is appearing from front end (check box values)
out of which i have few check box values which when selected it should be allowed, for other it shouldn't allow (display error message)
i have issue for third scenario that if 1 value is selected as per my list & other not in my list in this case it should display message
for ex list iam having is 'ABC' & 'PQR' and in check box selected values are 'ABC'&'XYZ'
for this i want to write sql query only, i tried regexp but not getting correct value please suggest on this;

Note values in column may be in any sequence

Here's an example of how to convert your string into rows you could then use in checking process. See if it helps.

Code: [Select all] [Show/ hide]

SQL> WITH test AS (SELECT 'XYZ,ABC,OPQ,PQR' col FROM DUAL)
  2      SELECT REGEXP_SUBSTR (col,
  3                            '[^,]+',
  4                            1,
  5                            LEVEL)
  6                result
  7        FROM test
  8  CONNECT BY REGEXP_SUBSTR (col,
  9                            '[^,]+',
 10                            1,
 11                            LEVEL)
 12                IS NOT NULL;

RESULT
---------------
XYZ
ABC
OPQ
PQR
