If the Relation Design window is open, the selected tables cannot be modified, even in Table Design mode. This ensures that tables are not changed while the relations are being created.


The selected tables are shown in the top area of the relation design view. You can close a table window through the context menu or with the Delete key.

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.

सम्बन्धहरू परिभाषित गर्नुहोस्

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.
