# Delete Table Constraint

Launch stage: GA

`DELETE /api/2.1/unity-catalog/constraints/{full_name_arg}`

Deletes a table constraint.

 For the table constraint deletion to succeed, the user must satisfy both of these conditions:
 - the user must have the **USE_CATALOG** privilege on the table's parent catalog,
   the **USE_SCHEMA** privilege on the table's parent schema, and be the owner of the table.
 - if __cascade__ argument is **true**, the user must have the following permissions on all of the child tables:
   the **USE_CATALOG** privilege on the table's catalog,
   the **USE_SCHEMA** privilege on the table's schema,
   and be the owner of the table.
