How do you check the performance of a query and how do you
optimize it?
Answer / guest
WE CAN EVALUATE THE QUERY PERFORMANCE BY RUNNING THE
EXECUTION PLAN OF THE QUERY.IF THE QUERY NEEDS ITS
PERFORMANCE TO BE OPTIMISED THEN WE WILL BE CREATE A VIEW
FOR THE TABLE USING 'WITH SCHEMA BINDING ' OPTION ,THEN
SUBSEQUENTLY CREATE A MATERIALISED VIEW USING INDEX
DEFINITION.FINALLY CHECK FOR THE EXECUTION PLAN (THAT
PREVENTS THE EXPENSE OF I/O READS).
