Description:

I have database name XXX_product and schema name as XXX_product and there is
a table "table_name" in schema XXX_product.The user I defined for
XXX_product and XXX_schema is user_postgres. 
Below query giving me the 0 rows.
"select tc.table_name AS TABLE_NAME, kcu.column_name AS
COLUMN_NAME,ccu.table_name AS REFERENCED_TABLE_NAME,ccu.column_name AS
REFERENCED_COLUMN_NAME FROM information_schema.table_constraints AS tc JOIN
information_schema.key_column_usage AS kcu ON tc.constraint_name =
kcu.constraint_name AND tc.table_schema = kcu.table_schema JOIN
information_schema.constraint_column_usage AS ccu ON ccu.constraint_name =
tc.constraint_name AND ccu.table_schema = tc.table_schema WHERE
constraint_type = 'FOREIGN KEY' AND tc.table_name='table_name' "

But when I am not using "JOIN information_schema.constraint_column_usage AS
ccu ON ccu.constraint_name = tc.constraint_name AND ccu.table_schema =
tc.table_schema" in the query I am getting the result.
