주의

With the UserDefinedFunction object, you can:

• Create a Microsoft SQL Server user-defined function.
• Change the definition of an existing SQL Server user-defined function.
• Control access rights to an existing SQL Server user-defined function.
• Delete an existing SQL Server user-defined function.
• Generate a Transact-SQL script to re-create a SQL Server user-defined function.

The Name property of a UserDefinedFunction object uses the SQL Server sysname data type. The value of the Name property must be unique (named by owner) within a SQL Server database.

To create a SQL Server user-defined function

1. Create a UserDefinedFunction object.

2. Set the Name property.

3. Set the Text property to contain the user-defined function.

4. Set optional property values.

5. Add the UserDefinedFunction object to the UserDefinedFunctions collection of a connected Database object.

After a user-defined function is created, you cannot reset the Name property. To change the name of a user-defined function, you must call the Remove method to drop and then re-create the object.

[!참고] The UserDefinedFunction object is compatible only with SQL Server 2000 and later.
