our system is quite big having around 100+ tables in schema. There was one business requirement for which we decided to handle it in stored procedures. In our application we have java as well but we chosen to use Stored Procedure. IN order to fulfill requirement created 3 functions. These functions are part of SQL query which get fired to fetch count and display records. Now we have SQL timeout set in connection which is set to 60 seconds. when we run this query for records of 40K, the operation gets timed out and we don't get any result. I am pasting here actual implementation of all these 3 functions and below them is query who makes use of all these created function.
In query below have marked function calling in Bold letter.
I am looking at your expert advice by which i can tune this implementation to work on 100K of data. we have oracle 11gR1.. Even this implementation is access from web in Ajax call.
Do let me know if you need anything else.
