Getting dates based on week number

I have some rows in my database that 开发者_如何学JAVAcontains some dates.

I need to select all dates based on a weeknumber, how is this possible?

The T-SQL DATEPART function will take week (abbreviated form wk) as its first parameter. This will do what you want. Reference here:

select date from table_name where DATE_FORMAT(date, "%U-%Y")="11-2010"

where 11 is week number

and 2010 is year
