SELECT product_lines.* FROM product_lines LEFT JOIN manufacturer_product_line_index ON manufacturer_product_line_index.product_line_id = product_lines.id WHERE product_lines.id IS NULL
-----Original Message----- From: Ed Lazor [mailto:[EMAIL PROTECTED] Sent: Thursday, April 07, 2005 11:39 AM To: mysql@lists.mysql.com Subject: Query question Three tables like this: -------------- product_lines -------------- id title -------------- manufacturer -------------- id title -------------- manufacturer_product_line_index -------------- id product_line_id manufacturer_id The index provides a one to many relationship - one product line can be associated with more than one company. How do I get a list of product lines not in the index?
