Alex Torin: "Several months ago I downloaded the trial versions of several Microsoft SQL administration tools that I was able to find using google. I had considerable trouble with most of them crashing... but using your product I was able to isolate and solve the problems I was having. I decided to add it to my toolkit and have recommended it to a few others".
Tracy J Powell: "Thank you VERY much for the quick and helpful response. I will definitely upgrade as soon as possible. Your products are great and I use them daily".

CLR UDFs

User-defined functions are routines that can take parameters, perform calculations or other actions, and return a result. In Microsoft SQL Server 2005, you can write user-defined functions in any Microsoft .NET Framework programming language, such as Microsoft Visual Basic .NET or Microsoft C#.
 

 

New CLR UDFs are created within Create CLR UDF Wizard. In order to run the wizard you should either

 

select the Object | Create Database Object... main menu item;
select the CLR UDF icon in the Create Database Object dialog

or

select the CLR UDFs list or any object from that list in the explorer tree;
select the Create New CLR UDF... item from the popup menu

or

open the schema in Schema Editor and the CLR UDFs tab there;
press the Insert key or select the Create New CLR UDF... item from the popup menu (alternatively, you may use the corresponding link of the Navigation Bar).

       

To create a new CLR UDF with the same properties as one of the existing CLR UDFs has:

 

select the Object | Duplicate Database Object... main menu item;
follow the instructions of Duplicate Object Wizard.

 

 

 

CLR UDFs can be edited within CLR UDF Editor. In order to run the editor you should either

 

select the CLR UDF for editing in the explorer tree (type the first letters of the CLR UDF name for quick search);
select the Edit CLR UDF ... item from the popup menu

or

open the schema in Schema Editor and the CLR UDFs tab there;
select the CLR UDF to edit;
press the Enter key or select the Edit CLR UDF item from the popup menu (alternatively, you may use the corresponding link of the Navigation Bar).

       

You can change the name of the CLR UDF using the Rename CLR UDF dialog. To open the dialog you should either

 

select the CLR UDF to rename in the explorer tree;
select the Rename CLR UDF item from the popup menu

or

open the schema in Schema Editor and the CLR UDFs tab there;
select the CLR UDF to rename;
select the Rename CLR UDF item from the popup menu (alternatively, you may use the corresponding link of the Navigation Bar).

 

 

 

To execute a CLR UDF:

 

select the CLR UDF in the explorer tree (type the first letters of the CLR UDF name for quick search);
select the Edit CLR UDF ... item from the popup menu;
execute the CLR UDF using the Execute link of the Navigation Bar

or

open the schema in Schema Editor and the CLR UDFs tab there;
select the CLR UDF to execute;
press the Enter key or select the Edit CLR UDF item from the popup menu, or use the corresponding link of the Navigation Bar;
execute the CLR UDF using the Execute link of the Navigation bar.

 

 

 

To drop a CLR UDF:

 

select the CLR UDF to drop in the explorer tree;
select the Drop CLR UDF item from the popup menu

or

open the schema in Schema Editor and the CLR UDFs tab there;
select the CLR UDF to drop;
press the Delete key or select the Drop CLR UDF item from the popup menu (alternatively, you may use the corresponding link of the Navigation Bar)

 

and confirm dropping in the dialog window.
