List Foreign Key Constraints -MS SQL
12 March,2007 by Jack Vamvas
A Foreign Key Constraint is defined when a table is modified or created. A Foreign Key enforces a relationship between data on two tables.
To list Foreign Key Constraints use this SQL code.
select c_c_u.table_name sr_c_table, c_c_u.constraint_name sr_c_constraint, c_c_u.column_name sr_c_col, k_c_u.table_name target_table, k_c_u.column_name target_col from INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE c_c_u, INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS r_c, INFORMATION_SCHEMA.KEY_COLUMN_USAGE k_c_u where c_c_u.constraint_name = r_c.constraint_name and k_c_u.constraint_name = r_c.unique_constraint_name order by c_c_u.table_name, c_c_u.constraint_name
