There is same problem with tmysql51connection ---------------------------------------------------------------------- BigChimp · 2013-01-22 13:55 1. Check the documentation e.g. the Lazarus release notes on the wiki about what MySQL connectors are available. I remember 4.0-5.5 being available; 5.5 may not be in stable versions, don't really know as I don't use mysql 2. Just download a 5.1 client and use it with tmysql51connection 3. If you search the forum and look at the wiki pages on mysql you'll find this advice as well... over and over and over and.... over. 4. Mysql is the only one with this ridiculous problem of new clients breaking compatibility. If you can, please consider moving to a real database such as Firebird or Postgresql. Good luck. PS: next time, please mention Lazarus, OS version etc. See my signature. Thanks.
