Dear satish,
Query the USER_CONSTRAINTS table to view all constraint definitions and names,
SELECT CONSTRAINT_NAME,CONSTRAINT_TYPE,SEARCH_CONDITION
FROM USER_CONSTRAINTS
WHERE TABLE_NAME='EMPLOYEES';
View the columns associated with the constraint names in the USER_CONS_COLUMNS view .
SELECT CONSTRAINT_NAME,COLUMN_NAME
FROM USER_CONS_COLUMS
WHERE TABLE_NAME='EMPLOYEES';
Hope this helps you,
regards,
maddy.
