Dumb question.

I know hot to disabled and enabled constraints.

How do I check for constraints for any given tables?

is there somekind of querry that I can run, to find out?


thank you,

If you are a dba then you can use the dba_constraints, if you are a user then you can use the user_constraints to view all the constrains under your schema.

SELECT * FROM dba_constraints;

or

SELECT * FROM user_constraints;

Good luck,
Sam

query user_constraints table to see STATUS column for
particular constraint.

e.g.
select constraint_name,status from user_constraints
where table_name = 'TABLE1';

No question is a dumb question.

There is a table called dba_constraints that keeps up with what constraints are on which tables. The main columns you will want to look at are probably owner, constraint_name, constraint_type (P is PK, U is UK, R is FK, C is Check), table_name, r_owner (referencing owner), r_constraint_name (referencing constraint).

select owner, constraint_name, constraint_type
from dba_constraints
/

If you do not have access to DBA_CONSTRAINTS, you might be better off using the ALL_CONSTRAINTS view, rather than USER_CONSTRAINTS.

ALL_CONSTRAINTS gives all the constraints that you have the privileges to see, whereas USER_CONSTRAINTS only has the constraints that you own.
