How can I find out what FOREIGN KEY constraint references a table in SQL Server?

Question

I am trying to drop a table but getting the following message:

Msg 3726, Level 16, State 1, Line 3

Answer 1

try the following query.

select object_name(sfc.constraint_object_id) AS constraint_name,
       OBJECT_Name(parent_object_id) AS table_name ,
       ac1.name as table_column_name,
       OBJECT_name(referenced_object_id) as reference_table_name,      
       ac2.name as reference_column_name
from  sys.foreign_key_columns sfc
join sys.all_columns ac1 on (ac1.object_id=sfc.parent_object_id and ac1.column_id=sfc.parent_column_id)
join sys.all_columns ac2 on (ac2.object_id=sfc.referenced_object_id and ac2.column_id=sfc.referenced_column_id) 
where sfc.parent_object_id=OBJECT_ID(
);

this will give the constraint_name, column_names which will be referring and tables which will be depending on the constraint will be there.
