Hi All,

 

I have a procedure which contains only one Select statement. The procedure take more time than expected to complete, the select statement inside the procedure was taking about 2 minutes to complete.

 

After running a Vacuum Analyze on the underlying tables the select statement could complete within seconds. But the procedure was still taking long time.

 

I tried after recreating the procedure, the procedure is taking only a few seconds after recreation.

 

Why the procedure is not getting the performance advantage of Vacuum analyse?  

 

Regards,

Anoo
