Description

Could not drop object 'Tmp_categories' because it is referenced by a FOREIGN KEY constraint. Query: IF EXISTS (SELECT 1 FROM sysobjects WHERE type = 'U' AND name = 'Tmp_categories')
BEGIN
DECLARE @tablename nvarchar(256), @constraintname nvarchar(256)
DECLARE refcursor CURSOR FOR
SELECT object_name(objs.parent_obj) tablename, objs.name constraintname
FROM sysobjects objs JOIN sysconstraints cons ON objs.id = cons.constid
WHERE objs.xtype != 'PK' AND object_name(objs.parent_obj) = 'Tmp_categories' OPEN refcursor
FETCH NEXT FROM refcursor INTO @tablename, @constraintname
WHILE @@FETCH_STATUS = 0
BEGIN
EXEC ('ALTER TABLE '@tablename' DROP CONSTRAINT '+@constraintname)
FETCH NEXT FROM refcursor INTO @tablename, @constraintname
END
CLOSE refcursor
DEALLOCATE refcursor
DROP TABLE Tmp_categories
END;
