EXPLANATION: here's the pertinent piece of my sql create statement:
ID INT NOT NULL AUTO_INCREMENT, PRIMARY KEY (ID)); i have used this create statement numerous times without this "problem". in the past, let's say i inserted 3 entries: A, B, and C. their IDs were 1,2, and 3. then i delete C from the database. when i then insert D its ID is 4. leaving 1,2, and 4 in the database. seems like this is safe and as it should be. all this morning, using the above example with a deviation...after i delete C and then insert D...D's ID is 3. if i delete B and C, then insert D and E...their ID's are 2 and 3. i was under the impression that once an ID had been used (in auto increment and as primary) it was gone. must i also make the ID "unique"? i can see why a primary key might need to be not UNIQUE (for concatenation of entries...etc), but i don't think i've done it iN the past (when it has incremented correctly). thanks ahead of time. query sql for the filter. jason wesley upton --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
