Hi,
I have 2 tables and I use both tables in many of my pl/sql procedures together.
I have indexes created on these tables on the columns separately.
We want to furthur imporove the performance of the queries where these two tables are involved.
So, can you please let me know how to create combined index on both the tables together?
like table A and table B having x and y columns.
x and y columns are currently indexed individually on the tables A and B.
Now I would like to create index on columns x and y columns on both tables in together.
Thank you in advance.
