Type Property (UserDefinedFunction)

未來的 Microsoft SQL Server 版本將移除這項功能。請避免在新的開發工作中使用這項功能,並規劃修改目前使用這項功能的應用程式。

The Type property returns the user-defined function type.

Inline function

SQLDMOUDF_Scalar

SQLDMOUDF_Table

2

SQLDMOUDF_Unknown

0

Unknown function type

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.

[!附註]

If an application calls Type on an instance of SQL Server version 7.0, the constant, SQLDMO_E_SQL80ONLY, and the message "This property or method requires Microsoft SQL Server 2000 or later" are returned.
