CLR UDTs
Microsoft SQL Server 2005 adds support for user-defined types (UDTs) implemented with the Microsoft .NET Framework common language runtime (CLR). The CLR is integrated into the SQL Server, and this new mechanism enables you to extend the type system of the database. UDTs provide user extensibility of the SQL Server data type system, and also the ability to define complex structured types.
New CLR UDTs are created within Create CLR UDT Wizard. In order to run the wizard you should either
| • | select the Object | Create Database Object... main menu item; |
| • | select the CLR UDT icon in the Create Database Object dialog |
or
| • | select the CLR UDTs list or any object from that list in the explorer tree; |
| • | select the Create CLR UDT... item from the popup menu |
or
| • | open the schema in Schema Editor and the CLR UDTs tab there; |
| • | press the Insert key or select the Create New CLR UDT... item from the popup menu (alternatively, you may use the corresponding link of the Navigation Bar). |
To create a new CLR UDT with the same properties as one of the existing CLR UDTs has:
| • | select the Object | Duplicate Database Object... main menu item; |
| • | follow the instructions of Duplicate Object Wizard. |
|
CLR UDTs can be edited within CLR UDT Editor. In order to run the editor you should either
| • | select the CLR UDT for editing in the explorer tree (type the first letters of the CLR UDT name for quick search); |
| • | select the Edit CLR UDT ... item from the popup menu |
or
| • | open the schema in Schema Editor and the CLR UDTs tab there; |
| • | select the CLR UDT to edit; |
| • | press the Enter key or select the Edit CLR UDT item from the popup menu (alternatively, you may use the corresponding link of the Navigation Bar). |
You can change the name of the CLR UDT using the Rename CLR UDT dialog. To open the dialog you should either
| • | select the CLR UDT to rename in the explorer tree; |
| • | select the Rename CLR UDT item from the popup menu |
or
| • | open the schema in Schema Editor and the CLR UDTs tab there; |
| • | select the CLR UDT to rename; |
| • | select the Rename CLR UDT item from the popup menu (alternatively, you may use the corresponding link of the Navigation Bar). |
|
To drop a CLR UDT:
| • | select the CLR UDT to drop in the explorer tree; |
| • | select the Drop CLR UDT item from the popup menu |
or
| • | open the schema in the Schema Editor and the CLR UDTs tab there; |
| • | select the CLR UDT to drop; |
| • | press the Delete key or select the Drop CLR UDT item from the popup menu (alternatively, you may use the corresponding link of the Navigation Bar) |
and confirm dropping in the dialog window.
