Move table and modify table size

You can resize and arrange the tables according to your preferences. To move tables, drag the upper border to the desired position. Enlarge or reduce the size in which the table is displayed by positioning the mouse cursor on a border or on a corner and dragging the table until it is the desired size.

Primary key and foreign keys

If you want to define a relation among the various tables, you should enter a primary key that uniquely identifies a data field of an existing table. You can refer to the primary key from other tables to access the data of this table. All data fields referring to this primary key will be identified as a foreign key.

Definir relaciones

All existing relations are shown in the relations windows by a line that connects the primary and foreign key fields. You can add a relation by using drag-and-drop to drop the field of one table onto the field of the other table. A relation is removed again by selecting it and pressing the Delete key.

If you use LibreOffice as the front-end for a relational database, the creation and deletion of relationships is not placed in an intermediate memory by LibreOffice, but is forwarded directly to the database.
