From DATE_FORMAT and back to origin date in mysql date column
SELECT DATE_FORMAT(dato, '%e/%c/%Y') AS dato FROM transportdokument WHERE dato = '2013-07-20' AND dato = '2013-07-24' GROUP BY dato DESC is working perfect in my PHP file. But I need to transfer the date back from my norwegian formatted date to the origin date format in WHERE dato = '$standard_date_format'; What need I do to fix this? Thanks for your time and help to learn me programming! Karl
Replication question
I have been asked to set up multiple database replication which I have done before for simple cases however there are some nuances with this instance that add some complexity and I'd like to hear your collective expertise on this proposed scenario:- 1) Single master database 2) n (probably 3 to start with) number of slave databases 3) All but 5 tables (123 tables in total) are to be replicated from the master to all the slaves 4) 3 tables from the slaves are to be replicated back to the master It is mainly item 4) that concerns me - the primary ID's are almost certain to collide unless I seed the auto increment ID to partition the IDs into separate ranges or does MySQL handle this issue? There are some foreign keys on one of the 3 slave to master tables but they are pointing at some extremely static tables that are very unlikely to change. Is the above a feasible implementation...?

RE: From DATE_FORMAT and back to origin date in mysql date column
I'm unclear on your task, but maybe this function will help: http://dev.mysql.com/doc/refman/5.1/en/date-and-time-functions.html#function_str-to-date (It is confusing to have dato as both a column name and an alias.) -Original Message- From: Karl-Arne Gjersøyen [mailto:karlar...@gmail.com] Sent: Wednesday, July 24, 2013 7:02 AM To: MySQL Mailinglist Subject: From DATE_FORMAT and back to origin date in mysql date column SELECT DATE_FORMAT(dato, '%e/%c/%Y') AS dato FROM transportdokument WHERE dato = '2013-07-20' AND dato = '2013-07-24' GROUP BY dato DESC is working perfect in my PHP file.

RE: Replication question
4) 3 tables from the slaves are to be replicated back to the master NO. However, consider Percona XtraDb Cluster or MariaDB+Galera. They allow multiple writable masters. But they won't let you be so selective about tables not being replicated. Here are the gotchas for Galera usage: http://mysql.rjweb.org/doc.php/galera If you can live with them (plus replicating everything), it may be best for you. -Original Message- From: rich gray [mailto:r...@richgray.com] Sent: Wednesday, July 24, 2013 8:21 AM To: mysql@lists.mysql.com Subject: Replication question I have been asked to set up multiple database replication which I have done before for simple cases however there are some nuances with this instance that add some complexity and I'd like to hear your collective expertise on this proposed scenario:- 1) Single master database 2) n (probably 3 to start with) number of slave databases 3) All but 5 tables (123 tables in total) are to be replicated from the master to all the slaves 4) 3 tables from the slaves are to be replicated back to the master It is mainly item 4) that concerns me - the primary ID's are almost certain to collide unless I seed the auto increment ID to partition the IDs into separate ranges or does MySQL handle this issue?
