How to Create Data Macros in Microsoft Access on Windows 11
Posted on 19th June 2023
What are Data Macros?
Data macros are macros that are associated with a table, and they run automatically when data in that table is added, changed, or deleted. Data macros can be used to automate processes, enforce business rules, and maintain data integrity.
Creating Data Macros
You can create data macros by using the Macro Builder (which is a graphical tool) or by writing Visual Basic for Applications (VBA) code.
To create a data macro by using the Macro Builder:
1. Open the table in Design view.
2. Click the Macro button in the Tools group on the Design tab.
3. In the Macro Builder pane, click the event that you want the macro to run for.
4. Click the plus sign (+) to add an action.
5. Select the action that you want the macro to perform, and then click OK.
6. Repeat steps 5 and 6 for each additional action that you want the macro to perform.
7. When you have finished adding actions, click Close.
Your data macro will now run automatically whenever the associated event occurs.
To create a data macro by writing code:
1. Open the table in Design view.
2. Click the Code button in the Tools group on the Design tab.
3. In the macros pane, click the event that you want the macro to run for.
4. Enter the VBA code that you want to run when the event occurs.
Your data macro will now run automatically whenever the associated event occurs.
Running Data Macros
Data macros run automatically when the associated event occurs. For example, if you have a data macro that runs when data is added to a table, the macro will run automatically whenever a new record is added to the table.
There is no need to run data macros manually. However, if you want to test a data macro, you can run it manually by using the RunMacro method.
To run a data macro manually:
1. Open the table in Design view.
2. Click the Code button in the Tools group on the Design tab.
3. In the macros pane, click the macro that you want to run.
4. In the code window, on the line before the End Sub statement, type the following line of code:
DoCmd.RunMacro “macroname”
Replace macroname with the name of the macro that you want to run.
5. Press F5 to run the macro.
In order to create a data macro, you first need to create a new macro. To do this, click the “Create” tab and then click “Macro”. This will open the Macro Builder.
In the Macro Builder, you will see a list of available actions on the left. To add an action to your macro, simply double-click it or drag it into the macro pane on the right.
There are two types of data macros: Before Change and After Change. Before Change data macros run before the data in the specified field is changed, and After Change data macros run after the data in the specified field is changed.
To specify which field the data macro should run on, click the “Field” button in the macro pane. This will open the Field List dialog box. Select the field you want the data macro to run on and then click the “OK” button.
Now that you have specified the field, you need to specify the actions that should happen when the field is changed. To do this, simply add the desired actions to the macro pane. For example, you might want to set the value of another field based on the value of the field you are changing.
When you are finished adding actions, click the “Close” button in the Macro Builder. This will save your macro and close the Macro Builder.
To test your macro, simply change the value of the field you specified and then save the record. If your macro is working properly, the other field should update automatically.
Data macros are a new feature in Microsoft Access 2010 that allows you to automate your database tasks. You can use data macros to automatically run a set of actions when a table is updated, deleted, or inserted.
To create a data macro, open the table in which you want to create the macro and click the Macro button on the ribbon.
In the Macro Builder window, select the action that you want to automate from the list of available actions.
After you have selected the action, enter the name of the macro and click the Run button.
Your macro will now be automatically run whenever the specified action is performed on the table.
You can also use data macros to automate your reports. To do this, open the report in which you want to create the macro and click the Macro button on the ribbon.
In the Macro Builder window, select the action that you want to automate from the list of available actions.
After you have selected the action, enter the name of the macro and click the Run button.
Your macro will now be automatically run whenever the specified action is performed on the report.
A data macro is a macro that is attached to a table and runs automatically when data in that table is added, changed, or deleted. Data macros can be used to enforce business rules, perform calculations, or update other tables.
To create a data macro, open the table to which you want to attach the macro and click the Macro button on the ribbon.
In the Macro Builder window, choose the event that will trigger the macro. For example, you can choose After Update to run the macro after data in the table is updated.
Then, choose the actions that you want the macro to perform. For example, you can choose to Set Value to set the value of a field in the table, or to Run SQL to run an SQL query.
Click the Save button to save the macro, then close the Macro Builder window.
The macro will now run automatically whenever the specified event occurs.
