In SQL Server I can use the SQL below to check if a constraint exists and if it's a primary key, trigger, etc.
SELECT *
FROM dbo.sysobjects
WHERE id = OBJECT_ID(N'[SCHEMA].[TABLENAME]')
AND OBJECTPROPERTY(id, N'IsPrimaryKey') = 1
What would be the Oracle equivalent because my query uses SQL Server specific tables to find the answer.
SELECT * FROM USER_CONSTRAINTS WHERE CONSTRAINT_NAME = 'CONSTR_NAME';
THE CONSTRAINT_TYPE
will tell you what type of contraint it is
To find out if an object is a trigger, you can query USER_OBJECTS
. OBJECT_TYPE
will tell you if the object's a trigger, view, procedure et al.
