HRESULT GetType(SQLDMO_UDF_TYPE *pRetVal);

備註
A scalar function is applied to all the rows in a table, thereby producing a single value (for example, an aggregate function). An inline function performs a single SELECT statement. A table function performs a series of Transact-SQL statements and returns the results as a table.
