I inherited a poorly created mysql database and now I need to migrate data to a new server.
Long story short, I need to keep it stored this way and I use phpmyadmin. Know of any tools to help the migration of this 1.2GB mysql table?
Hope I don't get slaughtered for this post...
MySQL Workbench (free as in beer, free as in speech) has dump and restore features.
http://dev.mysql.com/doc/workbench/en/wb-manage-server-data-dump-tab.html
Phpmyadmin and other admin tools also have those features, but web-based tools may not handle such a large table properly.
Dump your big table from your old server to a file on your desktop machine. Restore it to the new server. It may take overnight. So what? You only have to do it once (unless you mess it up the first time). Side benefit: you'll have a backup of your old table that you can put onto a DVD-RW and throw in your desk drawer.
You might have to segment the dump process by selecting rows a few million at a time. That's probably a good idea, because then you can restart the process if it crashes.
There are some tools (sqlyog) that can copy data from one server to another directly, as well.
Happy data wrangling.

I have a relatively large MySQL database (over 300 tables) which I desperately need to convert to PostgreSQL and synchronise data between the two databases if not real time then something close to it. Ideally I need a bi-directional data sync, or at least one directional - MySQL to Postgres sync.
I have managed to convert the database and import the data, but synchronisation seems to be a real problem.
This solution from DBConvert should supposedly do exactly that. After many days of trying to make it work I gave up. They don't even have a linux client which is strange considering that absolute majority of MySQL and Postgres database would run on linux servers.
Is there an alternative to DBConvert's solution that would do the same?
Check out Pentaho ETL tools Kettle and its client interface, Spoon. http://kettle.pentaho.com
boy, you have a job ahead of you in terms of bidirectional synchronization. This is hard on the best of days, and it poses a lot of problems.
The tool I would look at first, actually, would be RubyRep. This gives you a basic framework for replication between your databases, and it supports a number of RDBMS's.
The second thing you have to think about is what you are actually doing and why this is a really bad idea. Your biggest issue is conflict resolution and managing what happens if two different people update the same record on the different db's. This is not a trivial problem and it requires thinking through the actual workflows and scenarios carefully.

I have to make a database for 250 students which will have around 100-200 columns. Now its not possible to install MYSQL or anything like that on the server.All we can get is a shared folder on the server. The client side can have anything installed. There will be around 5-10 clients who will add,edit or delete the records. I though about SQLite as an option. Is there any security issues with it???
I need a database to be accessed by a 5 to 10 clients. We do not have a full server per se but rather a shared folder on a server. We therefore cannot install any server-side software, only client-side.
I would use SQLite. You could also use MS Access but consider that problems with old MS Access databases are common in companies where Access where used on the late nineties.
Have a look at the following questions here
https://superuser.com/questions/111798/small-database-recommendation-free
Free database for small datawarehouse
You will find enough information to get you started.
Else look at these
SQLite
HSQLDB

I have a large MySQL set of commands in a file (script) and I need to execute it on a Microsoft SQL Server 2008. I know there are few differences in both languages, despite the fact the base SQL is the same.
Is there any way how to convert a MySQL script to one that is executable on SQL Server? Or is there any migration app that can easily take the whole MySQL server and replicate everything on SQL Server 2008?
Thanks for any advice.
I tried Full Convert Enterprise with quite big success. Fast, easy and it did my job. Give it a try it may help you

I usually use MySQL Query Browser for my queries, but I always run into issues with the connections timing out and the Query Browser locking up, so I'm looking into alternatives. The new MySQL Workbench is much too slow and heavyweight, I prefer that the Administrative tools and the Query tools are separate (although it wouldn't be as much of a problem if the application wasn't so slow). I run on Ubuntu 10.04 x64. I'd like to avoid Windows/Wine-based solutions as much as possible. I also have had bad experiences (slow, buggy) with JVM-based MySQL applications, although perhaps other people know more lightweight ones.
I want something lightweight that can show me the schemas, tables, and column tree, and present a decent UI for editing tables.
Any suggestions would be appreciated.
I realize you want to avoid wine, but this might be a good suggestion for you as a free tool.
http://www.heidisql.com/
Although it does run on Java and may not be the prettiest thing ever, I pretty much always use Squirrel SQL client. If you haven't tried it, I recommend looking at it.
Squirrel SQL Client
+1 for HeidiSQL. On Arch Linux very easy to install. Get tarball from AUR;
Extract tarball to a directory.
In that directory: makepkg -s
After building package, install it with: pacman -U packagename
It works perfectly with wine. After trying some sql editors (Oracle SQL Developer, DBVisualizer, MySql Workbench) this was the best choice for me. Lightweigth & fast.
