Collect is not working

end //

when I query I am able to see the value for the string I am passing, but when iam collecting into an array it’s not working. throwing an error strs is not available. Appreciate for providing a solution
call str2arrfnq(’“TEST1”,“TEST2”,“TEST3”,’,’);
the requirement is converting a given comma separated line into an array.

What’s the full error message?

Also try using a column alias in your query to match the record definition like this:

q= select substr(indata,offset_start,regexp_instr(indata,’,’,1,i+1) - offset_start) as vars;

Also, since your query returns 1 row and 1 column, you can use SCALAR() instead. Moreover, your SELECT statements are not operating on table data at all, just SP variables and parameters, so you could just reference the expressions like

substr(indata,offset_start,regexp_instr(indata,’,’,1,i+1) - offset_start)

anywhere you need them, like on the right-hand side of an assignment statement, like:

myLocaVar = substr(indata,offset_start,regexp_instr(indata,’,’,1,i+1) - offset_start);
