If you execute sp_help without supplying an object name, the resulting report shows each object in sysobjects, along with its name, owner, and object type. Also shown is each user-defined datatype in systypes and its name, storage type, length, whether null values are allowed, and any defaults or rules bound to it. The report also notes if any primary or foreign-key columns have been defined for a table or view.
sp_help lists any indexes on a table, including those created by defining unique or primary key constraints. However, it does not include information about the integrity constraints defined for a table.
