Database management work can sometimes feel like navigating a maze, especially when faced with the challenge of removing or modifying fields.
Have you ever had to add the wrong field to a database? Or do you need to clean additional information from the classes in the DB? Now, let's see how to delete a particular field from the database.
We are adding a new model to the toolbox.
Select the properties of the new model and fill in a name and caption.
We save the model to reflect the changes.
Now, we need to add class traversal to the model. We will use the same tool that helped us in the model to create the 'Iterate Feature Classes' field.
The tool has been added to the model.
We will also look for an option to delete a field. From the geoprocessing window, search for 'Delete field.'
Drag and drop it to add it to the model.
From the catalog pane, find the database we are working with.
Use drag and drop to add our working database to the mode
Now, it's time to add the parameters and connect the elements.
Add the output of 'Iterate with Delete field.
Double click to open the options for deleting a field. Highlight the 'Name' field.
Validate and save the model, and it's time to run it.
Before running the model
After running the model
We have seen that our model works successfully. Now it's time to add parameters to it with the help of which we will be able to reuse it.
Also, add a field name as a parameter.
I used the create field pattern to re-add the fields we deleted a while ago.
Let's open it from the catalog and review the parameters. This is necessary so that we can see the name of the field that we are actually deleting.
Let's run it again.
After the field is deleted, geoprocessing automatically displays a warning that this field is not available.
