The return cursor(SYS_REFCURSOR) is too much slow
I have a table :"CUSTOMER" with two thousand of records, the required
time to retrieve this information with a query is less than 2
SELECT * FROM CUSTOMER
But i need get this information through a function that require more
than 2 MINUTES!!!
FUNCTION getCUSTOMER( ) RETURN SYS_REFCURSOR AS
OPEN cur FOR ' SELECT * FROM CUSTOMER ';
There is any database parameter that i need change ? Any suggestion,
Are you looking for a silver bullet like _do_it_faster=true?
