IT30468: QUERY RUN IN SPL IS MUCH SLOWER COMPARED TO QUERY RUN IN DBACCESS

APAR status

• Closed as program error.

Error description

• A specific query run from a stored procedure takes much longer
  than the same query being run from dbaccess.
  
  The stored procedure takes 11.29 secs vs .05 sec when run from
  dbaccess.
  
  The stored procedure chooses to use a sequential scan while
  dbaccess uses an index for the same query
  

Local fix

• Use a query directive to specify using an index.
