[PHP-DB] Please help me! :(
I have a site where things in the database have ids. When something new is added, it gets an id one higher than the highest existing id. I use code something like this: $gethighestid = mysql_fetch_array(mysql_query(select id from table order by id desc limit 1)); $tobeid = $gethighestid[id]+1; mysql_query(insert into table(id,othercolumn,othercolumn2) values('$tobeid','something','something')); The thing is, I just got two rows with duplicate ids. Aparantley, two people must of added two things at just the right times to make the same id. Is there any way that will reduce, or eliminate, the time gap between getting id and inserting? -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP-DB] Please help me! :(
Can I ask why you're not using autoincrement for your id field? If you used this you would never have the problem your having. Everytime a record is added it will increment the id field by one, so you don't have to use all the code your using.
