Finding week number of current date in current month in OBIEE

Reference to this post to which i gave reply, in OBIEE forums . 
question is: How to calculate the week of the current month. 
To be more clear if the date is: 1-aug-2009 then week is:1, if it’s 8-aug-2009 then week is: 2 .
Like this, the week number should be generated for given date column.
The solution is: use the CEILING(DAYOFMONTH(“D0 Time”.”T00 Calendar Date”)/7.00)functionality in OBIEE Answers
