Hi!
Pls, I need you.
I have a pl-sql procedure which take a long time to be executed. Due to an analisys make on this procedure, I saw there are two cursor that take too much time releted to the total time.
The query performed by these cursor are very complicated and involved more table that contains many data.
So, cause the cursor, for each row fetched, need to do other operations, the big amount of time is caused by the big amount of data.
Hence the question is: make sense to add index to the tables involved in the query used by the cursor, or use hints or use other similar solutions?
Thanks a lot to all.
Also the more simplex suggestion is appreciated.

Can't say anything without seeing the query, it's execution plan, statistics, table statistics ............
