2 In the Bindings panel (Window > Bindings), click the Plus (+) button, and then select Command (Stored

Procedure).

The Command dialog box appears.

3 Enter a name for the command, select a connection to the database containing the stored procedure, and then select

Stored Procedure from the Type pop-up menu.

4 Select your stored procedure by expanding the Stored Procedures branch in the Database Items box, selecting the

stored procedure from the list, and clicking the Procedure button.

5 Enter any required parameters in the Variables table.

You don’t need to enter any parameters for any RETURN_VALUE variable.

6 Click OK.

After you close the dialog box, ASP code is inserted in your page. When the code runs on the server, the code creates

a command object that runs a stored procedure in the database. The stored procedure in turn performs a database

operation, such as inserting a record.

By default, the code sets the Prepared property of the Command object to true, which makes the application server

reuse a single compiled version of the object every time the stored procedure is run. If you know the command will be

executed more than a few times, having a single compiled version of the object can improve the efficiency of database

operations. However, if the command will only be executed one or two times, using one might actually slow down your

web application because the system has to pause to compile the command. To change the setting, switch to Code view

and change the Prepared property to

false.

Note: Not all database providers support prepared commands. If your database does not support it, you might get an error

message when you run the page. Switch to Code view and change the Prepared property to

false.

If the stored procedure takes parameters, you might create a page that gathers the parameter values and submits them

to the page with the stored procedure. For example, you may create a page that uses URL parameters or an HTML form

to gather parameter values from users.

Building a registration page

About registration pages

Your web application can contain a page that requires users to register the first time they visit your site.

A registration page is made up of the following building blocks:

• A database table to store login information about the users

• An HTML form that lets users select a user name and password

You can also use the form to obtain other personal information from users.

• An Insert Record server behavior to update the database table of site users

•

A Check New Username server behavior to make sure the user name entered by the user is not taken by another user
