Budibase DB

This data source is the one that is native to Budibase. Any data you add here is stored directly on your Budibase instance.

Creating a table

You can create a table when you're in the data section in your application.

The recommended flow is to go to your Budibase DB instance from the sidebar, and then click the Create Table button. A shortcut to this is when you press the + button on the top left and choose Budibase DB.


Create a new table using this button

When creating a new Budibase DB table you can choose which built-in (auto types) columns you want to have. Each of these will be automatically maintained, created and updated based on the properties. You can choose to omit as you see fit. These can be added post-creation too through the "Create Column" method.



Auto ID

An automatically generated ID

Created by

The user who created the row

Created at

When this row was created

Updated by

The user who updated the row last

Updated at

The time when the row was updated last

CSV upload

When you already have existing data, you can import this using a CSV file when creating a table. This will automatically identify columns and create them for you, after which you can specify data types per column.

In the example below I imported a CSV with 4 columns representing a table of countries. After the file uploaded the screen below was shown.


As you can see, it automatically identified the 4 columns and allowed me to pick the data types for each column.

Adding columns

To add new columns to an existing Budibase DB table, navigate to the table you want to edit, then click the Create Column button on top of the table. This will display a dialog where you can configure the column you want to add.


Editing columns

  1. Step into the table through the sidebar
  2. Hover over the column name you want to edit
  3. Click the pencil icon

Selecting the display column

The display column is an important aspect when you're setting up relationships in tables. The column you select as a display column will be the one visually displayed inside a relationship column in another table.

Selecting a column during the table creation is only possible if you import data using a CSV file. To select a display column in any other situation, edit the column you want to make the display. This will give you the Use as table display column option as shown below.

External datasource constraints

You can add Budibase constraints to external table columns, however this is entirely for form validation and will not restrict the data that is saved.
Instead, you must add data constraints yourself to any external table schemas.
