There are three ways to view foreign key views in Navicat: direct access (find views starting with "FK_"), query the view (right-click "Query Data" from the view node), or expand INFORMATION_SCHEMA.KEY_COLUMN_USAGE table and use appropriate filters to identify foreign key references.
How to use Navicat to view foreign key views
Direct access
- Connect to the database.
- Expand the "View" node in the object tree.
- Look for views starting with "FK_", which represent foreign key relationships.
Query View
- Right-click the "View" node in the object tree.
- Select "Query Data".
- In the SQL Query Editor, enter the following query:
SELECT * FROM <view_name>
where <view_name></view_name>
is the name of the foreign key view you want to view.
Expand INFORMATION_SCHEMA.KEY_COLUMN_USAGE
Table
- Expand the "System Table" node in the object tree.
- Find and expand the
INFORMATION_SCHEMA.KEY_COLUMN_USAGE
table. - Use the following filter to view foreign key references:
-
TABLE_NAME
: The table where the foreign key resides -
CONSTRAINT_NAME
: The name of the foreign key constraint -
REFERENCED_TABLE_NAME
: The referenced table -
REFERENCED_COLUMN_NAME
: The referenced column
Example
Suppose we have a table named Customers
which contains a foreign key named customer_id
which references # The order_id
column in the ##Orders table.
- Direct access: In the object tree, expand the "View" node and find the name View for FK_Customers_Orders
.
- Query View: Right-click the FK_Customers_Orders
view and select "Query Data".
- Expand INFORMATION_SCHEMA.KEY_COLUMN_USAGE
Table:
In the filter, specify TABLE_NAMEas
Customers,
CONSTRAINT_NAMEis
FK_Customers_Orders,
REFERENCED_TABLE_NAMEis
Orders,
REFERENCED_COLUMN_NAMEis
order_id.
