Getting the part of data from DB2 query

Postby Balesh013GG » Thu Nov 22, 2012 10:20 pm

I have a column X which has the data like " XXXX YYY=(ZZZZ,AAAA) ". I just wanted to know how we can get the data that is enclosed within paranthesis.i.e ZZZZ,AAAA. I tried with SUBSTR but its giving an error with error message illegal ',' operand. Please suggest me how should I proceed with. Thanks!

Please show your attempt with SUBSTR.
The problem I have is that people can explain things quickly but I can only comprehend slowly.

select SUBSTR(PARM_VALUE,INSTR(PARM_VALUE,'(')+1,INSTR(PARM_VALUE,')')-INSTR((PARM_VALUE,'(')-1))..Here PARM_VALUE is the column name...

And what is the format of the SUBSTR function and its parameters?

select substr(columnname,instr(columnname,"(") + 1, instr(columnname,")")) as temp from tablename

This is the syntax for SUBSTR...

Wrong : SUBSTR(PARM_VALUE,INSTR(PARM_VALUE,'(')+1,INSTR(PARM_VALUE,')')-INSTR((PARM_VALUE,'(')-1))
Correct : SUBSTR(PARM_VALUE,INSTR(PARM_VALUE,'(')+1,INSTR(PARM_VALUE,')')-INSTR(PARM_VALUE,'(') - 1 )
I can explain it to you, but i can not understand it for you.

Hello,

You need to post the actual data used and the sql code you executed. Use the Code tags to preserve alignment and improve readability.
Hope this helps,
