Create Query with Two Tables
To set up using a search form to bring up specific
values from two tables, follow these steps:
- Create two pages, with the titles Search.asp and Results.asp.
- Open the Search.asp page.
- On the Insert menu, point to Form, and then click Textbox.
- Right-click the text box, and then click Form Field Properties on the shortcut menu.
- In the Name box, type ID, and then click OK.
- Right-click the text box, and then click Form Properties on the shortcut menu.
- Click to select the Send to other check box, click Options, and then type results.asp in the Action box. Click OK twice.
- On the File menu, click Save.
- Click Results.asp.
- On the Insert menu, point to Database, and then click Results.
- Click to select the Use a sample database connection check box, and then click Next.
- Click to select the Custom query check box, and then click Edit.
- In the SQL Statement box, type or paste the following text:
Select * From Categories,Products Where Categories.CategoryID=::ID:: and Categories.CategoryID=Products.CategoryID
NOTE: This returns all the columns from the Categories and Products table where the ID sent from the Search.asp page matches the CategoryID in the Categories table and the Category ID in the Categories table matches the CategoryID in the Products table. - Click OK.
- Click Next three times.
- Click to select the Display all records together check box, and then click to clear the Add search form check box.
- Click Finish.
- On the File menu, click Save.
- Open the Search.asp page.
- On the File menu, click Preview in Browser, and then click OK twice.
- In the text box, type 3, and then click Submit.
This returns all the columns from Categories and Products with a CategoryID of 3. If any valid ID is submitted, the correct records are returned.
