Lookup Columns

Lookup columns can be created, if there is a many-to-one relation between tables. These columns can be added to the Details table to represent a specific data from a related Master table (for example, the "Projects" table may need to contain the Client Company, Client Phone, Client E-mail from the related "Clients" table).

Using one relation you can add as many lookup columns as you need.

Furthermore, when a reference column of Many-To-One cardinality is created and a Proxy column is chosen in the reference column settings, the lookup column displaying Proxy column values is added to a table automatically.

When you create a new lookup column or edit an existing one, you have to fill in the displayed Lookup column form.
