for missing explanation ; I think Funtion is designed to return a value . When error handling is allowed , suppose an exception is raised , the return value is bound to restrictions . That may have been the reason to not allow the try catch handling in sql server.
please correct me if I am wrong.

Good question. I had to do a bit of research - I knew it wasn't allowewd in inline functions, but was unsure about multi-statement and scalar functions.

Nice question, good to remember.
I'm struggling to think what you'd be doing in a function that would require a TRY... CATCH :-)

I'm struggling to think what you'd be doing in a function that would require a TRY... CATCH :-)

Data conversions with possibly unclean data; computations that could generate an overflow, underflow, or divide by zero condition, etc.
Or maybe even lookups in a table that might not exist (I shudder at the thought of having to maintain a database where that is a serious possibility - but I've seen worse)
