Please send the "explain analyze YOUR_QUERY" output after first run and

Good Afternoon !!!
The view executes very faster for the first time.
When I execute the view again and again suddenly it gets slow or it
gets hang.
I have also traced the query plan but it changes for each
execution.Can we fix the query plan.
I have also tested the view on my test machine but the result was same.
The view contains multi-table joins.
Warm Regards,
Suresh Borse

Hello, Suresh
Maybe its taking long for the first time, and then its faster? Did you
noticed any circumstances under witch your query takes longer to execute?
