Answer / mani
While declaring the cursor include the null indicator for
the variables which you are retrieiving from the table.
Example.
Select empno,deptname from emp into
:ws-empno:ws-empno-ind,:ws-deptname:ws-deptname-ind
where empname='....'
Based on the values in ws-empno-ind,ws-deptname-ind we can
know whether the vaules being retrived are null are not.
If null indicator variable has a value -1 then the retrieved
value is null.
If you do no specify null indicator variable and the value
retreived is null then you would get -305 as the sqlcode.
The null indicator is declared as
05 ws-empno-ind s9(4) comp

Hi All, In a Cobol-DB2 program, I am fetching rows from 4 tables using cursor and then based on the a field present in that table, It processes the information accordingly..for example stat-c is one digit field..if stat-c is 'D' then the a row is deleted from table and written those details in to a file. If the stat-c is 'U' then a row is updated (hardcoded what to update)in a table and written those details in to a file. If the stat-c is 'I' then a row is inserted in a table and written those details in to two files. The issue is i have to include the intermediate commits. When an abend occurs, due to commit statement db2 tables will be saved, But there will be lose of file contents. When we resubmitting the job associated with this program there will be insert ,update and delete anomolies to avoid that what measures could be taken?. The intermediate commit is nothing but issuing commit after massive inserts, updates and deletes(sum of 500actions)
