Hi,

I defined the appropriate host variables in the working storage section and i'm using the same variables in the "WHERE CLAUSE" and "SET CLAUSE" of an UPDATE Statement.

EXEC SQL
UPDATE <Table-Name>
SET <Col1> = <:HV1>
WHERE
<Col1> = :<Hv2>;
End-Exec.

Kindly help me as soon as possible. I'm getting this error "Unused or Undefined Host Variable " even though i defined them in the working storage section. This is actually a COBOL, DB2 and CICS Program.

Regards,

GVNRao.

Hi Narayana,

Did u check whether the length of host variable is same as DB2 column?Better way i suggest is use the DCLGEN variables instead of using seperate variables.

Thanks,
Anu

Hi,

Thanx for ur reply. But i fixed it. But I have small doubt in that.
Earlier, i'm using a group data item at "01" Level in cobol say ws-exp-date, which is subdivided into DD, MM, YY. I moved this value to a host variable which is defined at "77" Level Number and i'm able to remove the problem. How this can happen?

Can anyone plz spend time to clear my doubts. Thanking you in anticipation.

Yours

Hi GV,

01 levels generally define the Host STRUCTURE for the row, not a column. You could have defined the host variable as an 05 level with no problem.

As Anu suggested it's better to INCLUDE the DCLGEN generated structure and use those Host variable names, because you can be sure they're defined properly.
