HI all

The problem is :

I am using compute node (esql)
I need variable susitution in this..

eg..
DECLARE VAR_FIRST CHARACTER 'OPCM_ACK';
DECLARE VAR_TWO CHARACTER 'VAR_'||'FIRST';


SET OutputLocalEnvironment.ABC = VAR_TWO;

Actually i want "OutputLocalEnvironment.ABC" contain value "'OPCM_ACK'"...
but it comes "VAR_FIRST"..


Is there any function to get that...

Have you tried something like

SET OutputLocalEnvironment.ABC = {VAR_TWO}; ?

Or looked into the EVAL function?

When you put a string in single quotes it is then a string literal. If you want to concatentate a literal with a variable remove the single quotes like this:

Code:
DECLARE VAR_TWO CHARACTER 'VAR_'|| FIRST;



Kind regards
