Hi,
Can anybody tell me in which system table the primary key information is stored in sql server 2005.
In sql server 2000, I could find the primary key info of a particular table(if it exist) in sysobject system table.But i am clueless about sql server 2005 .

Thanks,

Jude

You can use
sp_pkeys table_name

this works in 200, 2005, 2008

select * from INFORMATION_SCHEMA.TABLE_CONSTRAINTS WHERE Constraint_Type = 'PRIMARY KEY'

can add WHERE table_name = 'YourTable' if looking for a particular table

this works in 2005+

select * from sys.indexes where is_primary_key = 1

Thanks for replying.
Well i am not looking for a query that fetches primary key info.
I wanted the name of the system table (like sys.sysallocunits, sys.sysrowsets, sys.sysrowsetcolumns etc) that holds this information.

What is wrong with INFORMATION_SCHEMA.TABLE_CONSTRAINTS?
