यहाँ तपाईँले हालको डाटाबेसलाई साझा डेटा फाँटहरू हुदै दुबै तालिकाहरू लिङ्क गर्न सक्नुहुन्छ । सम्बन्धहरू सिर्जना गर्न नयाँ सम्बन्ध प्रतिमा क्लिक गर्नुहोस्, वा सामान्यरूपमा माउस सँग तानेर छोड्नुहोस् ।

When you choose Tools - Relationships, a window opens in which all the existing relationships between the tables of the current database are shown. If no relationships have been defined, or if you want to relate other tables of the database to each other, then click on the Add Tables icon. The Add Tables dialog opens in which you can select the tables with which to create a relation.
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.
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.
