Dynamic methods are frequently problematic, but to get the data you're looking for, check out the system views available under the schema called INFORMATION_SCHEMA. They should supply you with everything you need.

I tried to get the above qry. could you please check and verify this query...

select s.name schemaname, o.name tablename, i.name identitycolname,

ins.constraint_name constraintname

from sys.schemas s

join sys.sysobjects o on o.uid = s.schema_id

left join sys.identity_columns i on o.id = i.object_id

left join information_schema.constraint_table_usage ins on

ins.tabnle_name = o.name

and ins.constraint_name in ( select insc.constraint_name from

information_schema.referential_constraints insc )

where o.xtype = 'U'

order by s.name, o.name

Thanks in advance..

you just miss spelled the table_name as tabnle_name 🙂 nothing else is the problem.

It really depends on your needs. That query is returning the data you outlined.

Okay how about taking this one step further, and show the column names that are in the Foreign Key? Is there a way? Each time I attempt that I end up with errors.

Hello!

Something like this:

SELECT

CTU.TABLE_SCHEMA + '.' + CTU.TABLE_NAME

,

KCU.COLUMN_NAME [COLUMN],

CTU2.TABLE_SCHEMA + '.' + CTU2.TABLE_NAME [REFERENCED_TABLE],

KCU2.COLUMN_NAME [REFERENCED_COLUMN],

CTU.CONSTRAINT_NAME [FK_CONSTRAINT]

FROM INFORMATION_SCHEMA.CONSTRAINT_TABLE_USAGE CTU

JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE KCU ON KCU.CONSTRAINT_NAME = CTU.CONSTRAINT_NAME AND KCU.CONSTRAINT_SCHEMA = CTU.CONSTRAINT_SCHEMA

JOIN INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS RC ON RC.CONSTRAINT_NAME = CTU.CONSTRAINT_NAME AND RC.CONSTRAINT_SCHEMA = CTU.CONSTRAINT_SCHEMA

JOIN INFORMATION_SCHEMA.CONSTRAINT_TABLE_USAGE CTU2 ON CTU2.CONSTRAINT_NAME = RC.UNIQUE_CONSTRAINT_NAME AND CTU2.CONSTRAINT_SCHEMA = RC.UNIQUE_CONSTRAINT_SCHEMA

JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE KCU2 ON KCU2.CONSTRAINT_NAME = RC.UNIQUE_CONSTRAINT_NAME AND KCU2.CONSTRAINT_SCHEMA = RC.UNIQUE_CONSTRAINT_SCHEMA

WHERE CTU.TABLE_NAME = 'tablename'

AND CTU.CONSTRAINT_NAME LIKE 'FK_%'
