Answer / sesha
-811 results when
1)Execution of an embedded SELECT statement has resulted in
a result table containing more than one row.
2)Alternatively, a subquery contained in a basic predicate
has produced more than one value.
Solution is:
Examine the syntax of the statement to ensure that it
contains the proper condition specifications. If it does,
there may be a problem with the data that is causing more
than one row or value to be returned when you do not expect
it.
You can use cursor to overcome this problem.

How to test SQL -911 error while developing COB-DB2 program
What technique is used to retrieve data from more than one table in a single SQL statement?
Explain about rct.
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)
