Hi All,

Can i have to know while a query is getting executed then...What type of wait do we see ...

If the query is using parallelism ?...Is there any way we can forcibly use parallelism for a query?

If the query is not using Parallelism.. is there any way to know… why the Parallelism was not used for that query while running ?

Can any one please suggest...!!
