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?
