product: | |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 | |
Problem description: | |
Compiling a query with an optimization guideline that includes a join request with the FIRST attribute may result in the following error: SQL0901N The SQL statement failed because of a non-severe system error. Subsequent SQL statements can be processed. (Reason "sqlno_crule_join [350]:rc( 0) ".) SQLSTATE=58004 Here is an example of such an optimization guideline: <OPTGUIDELINES> <NLJOIN FIRST="TRUE"> <ACCESS TABLE="TABLE1"/> <ACCESS TABID="Q10"/> </NLJOIN> </OPTGUIDELINES> This can happen if no valid query plan can be generated using the guideline. Under normal circumstances, if a guideline cannot be used, the optimizer should ignore the guideline and generate a valid plan. | |
