I used to do the below script to find Foreign Key tables associated with Primary Key table.
DECLARE @TableName VARCHAR(32) = 'Your Primary Key Table Name' -- Pass your table name here SELECT o1.name AS FK_table ,c1.name AS FK_column ,fk.name AS FK_name ,o2.name AS PK_table ,c2.name AS PK_column ,pk.name AS PK_name ,fk.delete_referential_action_desc AS Delete_Action ,fk.update_referential_action_desc AS Update_Action FROM sys.objects o1 INNER JOIN sys.foreign_keys fk ON o1.object_id = fk.parent_object_id INNER JOIN sys.foreign_key_columns fkc ON fk.object_id = fkc.constraint_object_id INNER JOIN sys.columns c1 ON fkc.parent_object_id = c1.object_id AND fkc.parent_column_id = c1.column_id INNER JOIN sys.columns c2 ON fkc.referenced_object_id = c2.object_id AND fkc.referenced_column_id = c2.column_id INNER JOIN sys.objects o2 ON fk.referenced_object_id = o2.object_id INNER JOIN sys.key_constraints pk ON fk.referenced_object_id = pk.parent_object_id AND fk.key_index_id = pk.unique_index_id WHERE o2.name = @TableName ORDER BY o1.name ,o2.name ,fkc.constraint_column_id
This script will helpful in below scenarios
1.Data archival from one table to other table
- We need to disable FK constraints to move only
Primary key data to archival tables.
2.To delete only parent table data and keeping data in child table
In order to achieve the above scenarios we need to find PK and FK relation ships with help
of this scripts.
