Steps to set validation rules to non-empty in Access

In Access, you can set validation rules to ensure that data input is not empty and prevent user input from empty values. Here's how to set up the rule:

1. Select the field for which you want to set the validation rule

Select the field for which you want to set the rule in Table View or Design View.

2. Open the Field Properties box

Right-click the selected field and select Properties from the menu.

3. Switch to the "Validation Rules" tab

In the "Field Properties" box, switch to the "Validation Rules" tab.

4. Enter the validation expression

In the "Validation Rule" box, enter the following expression:

<code>NOT IsNull([Field Name])</code>

Replace "[Field Name] ” with the name of the field for which you want to set the rule.

5. Enter validation text

In the Validation Text box, enter a message to be displayed to the user if they enter a null value. For example:

<code>此字段不能为空。</code>

6. Click "OK" to save the changes

Click the "OK" button to save the validation rules.

Effect

Now, when the user attempts to enter a null value into the field, Access will display the error message you entered in the Validation Text box. This will ensure that the user always enters a non-null value.
