Hi,
I am running my oracle queries but these are taking 20 to 25 min to display the results .
but on server it is taking some seconds. so how can i resolve my problem ?

Queries are just select statement but i am getting records from view not from table . some one suggest me to use sqlplus but i don't know how to use.

I have to just export the report in to excel

Thanks,
Manisha

Based on the info you provided, you are using a view in the report. Is it ASP.NET report viewer? or Oracle reports?

First run view in db with exact input parameter(s) you used to view the report, note down the performance.

If the performance is OK with direct view execution then check the report for any custom processing like - expressions to evaluate a report column or custom coding inside the report. Sometimes, the custom coding takes considerable time because the report viewer uses code interpretatin at runtime.
