         SET @ReturnValue = @value
         RETURN @ReturnValue

END TRY
BEGIN CATCH
    IF @@TRANCOUNT > 0
        ROLLBACK TRAN --RollBack in case of Error
    select ERROR_MESSAGE()
END CATCH

I am preparing a very long script and try to implement the transaction in the script so in case if there will be any error in my script it will not effect my database. But I am getting the error Create function must be the only statement in the batch when implementing transactions.

Please help.

I think the documentation on functions is pretty clear:

User-defined functions cannot be used to perform actions that modify the database state.

COMMIT / ROLLBACK definitely fall into this category.

Use a stored procedure instead.
