Hi Suki,
No circular reference is allowed.
You will have to store this Parent_ID with Cat_ID in different table to
achieve this.

Hi friends,
I have a self referencing table as follows.
[SQL 2000]
CREATE TABLE Tbl_Category
(
Cat_ID
int
IDENTITY (1, 1) NOT NULL,
Cat_Name
varchar(50) NULL,
Parent_ID
int NOT
NULL,
CONSTRAINT pk_Category PRIMARY KEY NONCLUSTERED
(Cat_ID)
)
GO
ALTER TABLE Tbl_Category ADD
CONSTRAINT RefConstCategory
FOREIGN KEY
(Parent_ID)
REFERENCES
Tbl_Category(Cat_ID)
ON DELETE
CASCADE
GO
Note that the field Parent_ID referes to field
Cat_ID.
I'm facing a problem while trying to create a ON DELETE
CASCADE on the same.
Please advice me
Thanx,
Suki
