Query Execution Time

Hi Everyone..

I have been using some join statements to get the data. But I wanted to use the Belongs:to , has-many , one-one, many to many Relation ships to reduce my query processing time.

So I have applied it and every thing is working fine.

I just want to print the query execution time on my screen using yii framework.

I just want to check the time taken by two queries.

Is there any to measure the query execution time.
