Toad Data Modeler and its behavior can be easily customized in several ways. One of the ways to customize Toad Data Modeler is by creating a macro.
Macros help you automate tasks. It’s an action (or several actions) that you can run repeatedly. Read more about macros in the Toad Data Modeler User Guide, page 534.
In this blog tutorial, you will learn how to create a macro and how to assign attributes with data type char(50) domain "DomainCity" for the Oracle models.
In order to do this it is required that you enable Expert Mode, from Settings-Options-General.

Toad Data Modeler allows you to save all customization to packages. There are three types of packages:
System packages are packages that are made by a Toad Data Modeler developer team and it is not recommended to make any change to these packages. Packages are stored under an install folder, by default in a program files folder.
User packages are all packages that have been created by user. It is the right place to store our customization.
My Package is a very specific package that is visible from all database packages. It can be used for macros that are valid for all Toad Data Modeler models or some simple changes.
In our example we will create a user package.
Go to Main Menu - Expert Mode - Customization - New Custom Package.

When you select a new package it’s very important to select the right extension. For the purpose of this exercise, we will select package "Database Oracle" as extension of package "DomainAssign."
|Extension is very important. When you want to extend the functionality of Oracle, you need select "Database Oracle" package. When you want to do modification for Oracle 19c only you will set package "Database Oracle 19c.” When you want to do a modification for all physical models you need to select "Physical Entity Relationship Model" etc.|

After you commit this dialog, go to "Main Menu - Expert Mode - Customization - Package Explorer" to open a package explorer. Open the package explorer, and confirm that your new package is listed. Because there are a lot of packages I recommend to filter out system packages by Icon from a toolbar.

Now, select the DomainAssign package in the Package Explorer and right click to open a "Package Properties" dialog. Go to a "Visibility" tab and set Visibility to Oracle.

Press the OK button and package is ready.
If you want to locate this package in your HDD, then you can open the "Package Properties" window and on the general tab you’ll see a field that shows the full path to the file.

Go to the Package Explorer to the DomainAssign package and expand it.
Go to the folder "Macros" and right click. From context menu choose "Add Macro.”

It will be called "Macro1" by default. Right click on the macro and from a context menu choose "Properties." Next, I’ll show you how to create the proper macro settings.
Set a Name and a Caption of macro.
The caption is used for display in menu and the name for identification.
The Name cannot contain any spaces.

Go to the Visibility tab. Set the visibility the same as you did for the Oracle package.

Go to the Menu tab. Each macro can be accessible from the Macros Properties ‘Macro 1’ Main menu tab. Add to Main Menu is selected by default. In this demonstration we will also select Add To Popup Menu.
Select "Add to Popup Menu" (Additionally, you could specify in Path fields in the submenu to sort our macro.)

Go to the Object Types tab. On this tab you can specify objects in a which context menu will be the macro accessible. Select "Model" and "Workspace" on a "Physical Model" tab. Because we set workspace, it will be accessible from the context menu of a designer. Because we set "Model" it will be accessible from a model node of a Model Explorer and a View Explorer.
Click OK to confirm all modifications.

Create a new Oracle 19c model. At the Toad Data Modeler main menu bar, go to the Macros tab and you should see a new item "Assign Domain to Attribute."

Similarly, when you right click on a designer or on a model node in a model explorer, you can see in the context menu a new item, “Assign Domain to Attribute.”

Now we have a macro, but it doesn’t do anything … yet.
Lets go to the "Package Explorer", and double click on the macro "AssignDomainToAttribute." It opens a "Script Editor" with this macro.
Screen shot script editor AssignDomainToAttributes.
You can see that there are some a default code that you can choose to use or not use.
But first we need to create a dialog for selection of a domain.
It will be a simple dialog, with one combo box. In this combo box will be all domains from a model. We will modify source code of the main function.
Screen shot showing Main Method source code.
At the begin of method some global objects to variables are stored. It is a model and a log for some messages.
Next, create a dialog with one label and one combo.
We will register our variables Model and Log via method "RegisterObject" to be accessible in dialog events.
On the end of method is defined Execute method, which will be in the same script and command for show dialog.
On Line 23 is used method LoadItemsToDomainsCombo. Below is the code.
Screen shot showing LoadItemToDomainsCombo source code.
Now we need a code to assign domain to attributes.
Screen shot showing code to assign domain to attributes.
You can see in the method. As we Execute, we go through all the attributes in the model and if the attribute is of data type char(50), then it has an assigned domain.
Now we can try the macro. When you run it, you should get this dialog:
Screen shot dialog Domain1.
In the combo are all domains from the model.
When you press the execute button, you will see in message explorer a list of attributes which has been changed.
