Cursor Help Please

I have a requirement for a user to access time sheet information by accessing a SharePoint portal listing. They will be required enter a date range. The login will be based on their domain access.

Based on the query below, I can return a result set which gives the user all rows they'll need, grouped accordingly and based on a date range. Except for a required billable percentage figure. A billable percentage is defined as billable hours / total hours * 100 or based on the query below;

day1 through 7_hr1 [Worked_hrs] where the project <> admin (@.Worked_hrs_B), divided by the total [Worked_hrs](@.Total_Worked_hrs).

I'm pretty sure I need to use a cursor which will tally all the @.Worked_hrs_NB rows, and another cursor which will tally @.Total_Worked_hrs rows and then divide the two variables * 100, to return it in the @.Billable variable.

This is where I get lost. I'm ashamed to say that my TSQL is rusty & weak at best. Rather than confuse anyone with my idea of cursor syntax, I left it out of this query, & just included the variables I assumed would fit.

A down'n'dirty cursor lesson would be most appreciated (If that's what this needs). Thanks in advance for your help.

You don't really need a cursor. You can write two queries that performs the required SUM operations and divide the results. For example:

select (select sum(...) from ....)/((select sum(...) from ...)*100.0) as billable_per

See Books Online for more details on how to write scalar queries, group by, expressions etc.
