QUESTION ONE: How does one suppress duplicate row entries? QUESTION TWO: In the following case what is causing them to occur? BACKGROUND: I created several tables only to discover that they were not as I wanted them. AFter truncateng each, I dropped what I believed to be poorly structured columns, rearranged some, and added still others. When I tested the result, everything worked great except for one problem -- a single table entry reuslted in duplicate rows. THE TABLE STRUCTURE CREATE TABLE 'table_name' (obs` int(5) NOT NULL AUTO_INCREMENT . . . PRIMARY KEY (`obs`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 A SAMPLE SQL STATEMENT INSERT INTO rss2_podcast_itunes (podcast_no_itunes, itunes_category1, itunes_category2, itunes_category3, itunes_complete, itunes_new_feed_url, itunes_name, itunes_email, itunes_duration, itunes_order, itunes_author, itunes_block, itunes_image, itunes_explicit, itunes_summary) VALUES ('54', 'education', 'language', 'English', '', '', 'Roddy A. Stegemann', 'email@example.com', '00:01:01', '', 'Roddy A. Stegemann', '', 'http://www.grammarcaptive.com/_images/captive.png', '', 'Test') Please note the following: No value is entered for the obs field/column. The auto increment advances one for each row entered. Below each successfully loaded row entry appears another row identical in every way but one -- the appearance of an incremental advance in the value of the obs field. Please advise. Roddy
