Access – Delete with INNER JOIN

ukrainskadiaspora — Wed, 02 Sep 2009 13:44:00 +0000

Here is my problem. The following sql statement will give me an error:

Delete * from email Inner Join [Emails Delete 1] ON email.ToAddress = [Emails Delete 1].ToAddress

Error message is specify the table containing the records you want to delete or if I modify the statement I am getting another one Syntax Error (Missing Operator) in query expression’

To Fix it:
1. Create query that will load emails to delete:
SELECT Email.ToAddress, Count(Email.ToAddress) AS CountOfToAddress
FROM Email
GROUP BY Email.ToAddress
HAVING (((Count(Email.ToAddress))>3))
ORDER BY Count(Email.ToAddress) DESC;

2. Create query that will delete emails
DELETE *
FROM Email
WHERE Email.ToAddress IN (Select ToAddress from [Emails Delete 1]);
