Properties
Methods
Remarks
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
- Create a UserDefinedFunction object.
- Set the Name property.
- Set the Text property to contain the user-defined function.
- Set optional property values.
- 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.
Note The UserDefinedFunction object is only compatible with SQL Server 2000.
