Delete from multiple tables in one query
Never had a need to do this till today, but here's how you can delete from three tables in one query. Below is the SQL i used on a MySQL DB.
<cfquery datasource="#request.dsn#" name="delQry">
DELETE FROM
table_1, table_2
USING
table_1, table_2
WHERE
table_1.id = table_2.id
AND
table_1.id = 1
</cfquery>
DELETE FROM
table_1, table_2
USING
table_1, table_2
WHERE
table_1.id = table_2.id
AND
table_1.id = 1
</cfquery>
