Hi ,

i found the following code snippet:
{ fn WEEK(Created) }

It does select the week from a date.
The fucntion week is not supported by t-sql.
only when i use the keyword FN before it is supported.

Know my question?
What does FN mean and where is the function week implemented?

regards martin

Seems like an ODBC-function.

No. FN makes your connection resort to ODBC level calls and use the WEEK function and calculate the week value for created column.
It will be faster to use DATEPART(WEEK, Created) instead.

Peter, any idea where I can get a list of these ODBC functions?

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.
Although change is inevitable, change for the better is not.
Just because you can do something in PowerShell, doesnt mean you should. Wink
