Delete rows from multiple tables using a single qu

Question

This is the query I'm using:

 DELETE TB1.*, TB2.*
   FROM TB1
        INNER JOIN TB2 ON TB1.PersonID = TB2.PersonID 
  WHERE (TB1.PersonID)='2'

It's working fine in MS Access but getting error (Incorrect syntax near ','.) in SQL Server Express 2005.

How to solve it? Please help.

Answer 1

I don't think you can delete from multiple tables at once (though I'm not certain).

It sounds to me, however, that you would be best to achieve this effect with a relationship that cascades deletes. If you did this you would be able to delete the record from one table and the records in the other would be automatically deleted.

As an example, say the two tables represent a customer, and the customer's orders. If you setup the relationship to cascade deletes, you could simply delete record in the customer table, and the orders would get deleted automatically.

See the MSDN doc on cascading referential integrity constraints.

Answer 2

Try this query

DELETE TB1, TB2 FROM TB1 INNER JOIN TB2  
WHERE TB1.PersonID = TB2.PersonID and TB1.PersonID = '2'

Answer 3

Specify foreign key for the details tables which references to the primary key of master and set Delete rule = Cascade .

Now when u delete a record from the master table all other details table record based on the deleting rows primary key value, will be deleted automatically.

So in that case a single delete query of master table can delete master tables data as well as child tables data.

Answer 4

As i know, you can't do it in a sentence.

But you can build an stored procedure that do the deletes you want in whatever table in a transaction, what is almost the same.

Answer 5

DELETE TB1, TB2
    FROM customer_details
        LEFT JOIN customer_booking on TB1.cust_id = TB2.fk_cust_id
    WHERE TB1.cust_id = $id

Answer 6

Why you don't use a DELETE CASCADE FK ?
