Work with table relationships

Table relationships define the ways that table records can be associated with records from other tables or the same table. There are three types of table relationships. Dataverse for Teams allows for the creation of the same relationship types as Dataverse does:

  • One-to-many relationships. In this type of relationship, each row in table A can match more than one row in table B, but each row in table B can match only one row in table A. For example, a class of students have a single classroom.

  • Many-to-one relationships. In this type of relationship, each row in table B can match more than one row in table A, but each row in table A can match only one row in table B. For example, one single teacher teaches many classes.

  • Many-to-many relationships. In this type of relationship, each row in table A can match more than one row in table B, and vice versa. For example, students attend many classes, and each class can have multiple students.

    Or, on the left pane, expand Tables, expand the table you want, and then select Relationships.

  1. When the relationships page is open, select Add relationship, and then select the type of relationship you want to create (for example, Many-to-one).

Note

When defining columns of type lookup within a table, a many-to-one relationship is created automatically.

Edit a table relationship

Editing relationships in Dataverse for Teams works the same as Dataverse except that you can't manage collaboration functions, such as allowing feedback or enabling SharePoint document management. More information: Relationship actions

Delete a table relationship

While viewing table relationships, select the table relationship you want to delete, and then do one of the following:

  • Select Delete relationship on the command bar.
