UserDefinedFunctions Collection
Dieses Feature wird in einer zukünftigen Version von Microsoft SQL Server entfernt. Verwenden Sie dieses Feature beim Entwickeln neuer Anwendungen nicht, und planen Sie das Ändern von Anwendungen, in denen es zurzeit verwendet wird.
The UserDefinedFunctions collection contains UserDefinedFunction objects that reference the Microsoft SQL Server user-defined functions.

Hinweise
With the UserDefinedFunctions collection, you can:
- Create a user-defined function.
- Remove a user-defined function.
For more information about creating user-defined functions by using the UserDefinedFunction object and UserDefinedFunctions collection, see UserDefinedFunction Object.
To remove a user-defined function
Use the Item or ItemByID method to reference the targeted user-defined function through the UserDefinedFunction object in the UserDefinedFunctions collection. When extracting a UserDefinedFunction object using the name of the referenced user-defined function, use the owner name to qualify the name, as in:
Set oUDF = _ oDatabase.UserDefinedFunctions("SummarizeSales", "dbo")
Use the Remove method of the UserDefinedFunction object to remove the targeted user-defined function.
When using the Item or Remove method, the UserDefinedFunctions collection supports member identification using either name or ordinal reference syntax. For example:
Set oUDF = _
oDatabase.UserDefinedFunctions("SummarizeSales", "dbo").Remove
Or:
Set oUDF = oDatabase.UserDefinedFunctions(1).Remove
Additionally, when using name-based item selection, the Item method allows qualification by owner name of the targeted SQL Server user-defined function, as shown earlier. When using the Remove method, the UserDefinedFunctions collection supports qualification of the targeted object by owner name if the Remove method contains a string with a valid owner name as a parameter. If the Remove method contains an integer as a parameter, no owner name can be specified. In this case, it is suggested that you use the Item method to extract the target, and then use the Remove method of the UserDefinedFunction object to drop a user-defined function.
