When DB2 executes SQL statements, it returns the results of the operation into the SQLCODE and SQLSTATE fields in the SQLCA. SQLCODE provides key information about the success or failure of SQL statement execution.

If SQLCODE = 0, execution was successful.
If SQLCODE > 0, execution was successful with a warning.
If SQLCODE < 0, execution was not successful.
If SQLCODE = 100, “no data” was found. For example, a FETCH statement returned no data because the cursor was positioned after the last row of the result table.

SQLCODE – Successful SQL Execution

SQL Return Code +231 CURRENT POSITION OF CURSOR cursor-name IS NOT VALID FOR FETCH OF THE CURRENT ROW.

Suggestion: Be certain to FETCH to position on a row after opening a cursor. If cursor is declared SENSITIVE STATIC SCROLL, the row may be a hole, from which no values can be fetched.

SQL Return Code +304 A VALUE WITH DATA TYPE data-type1 CANNOT BE ASSIGNED TO A HOST VARIABLE BECAUSE THE VALUE IS NOT WITHIN THE RANGE OF THE HOST VARIABLE IN POSITION position-number WITH DATA TYPE data-type2.
Suggestion: Verify DCLGEN host variable definitions are current with DB2 catalog table/view attributes.

SQL Return Code +347 THE RECURSIVE COMMON TABLE EXPRESSION name MAY CONTAIN AN INFINITE LOOP.
Suggestion: Verify predicate in the SQL WHERE clause of the form “counter_col < constant” or “counter_col < :hostvar”.

SQL Return Code +802 EXCEPTION ERROR exception-type HAS OCCURRED DURING operation-type OPERATION ON data-type DATA, POSITION position-number.
Suggestion: Check arithmetic operation for divide by zero or result to exceed size of host variable.
