Re: uninstall/reinstall
We're talking about a Windows machine, right? I don't have any of those these days but it sounds to me like it didn't thoroughly uninstall. If that much is correct, I'd first be suspicious of junk left in the registry or data directories. Even if it meant I had to install it again, I'd use a separate uninstaller. Uninstallers are usually a little more aggressive about getting to the registry and data directories and stuff of that nature. The one I used to use is free and, in my experience, quite good. Revo Uninstaller [ http://www.revouninstaller.com/revo_uninstaller_free_download.html ] If that doesn't do it, then I would try cleaning out the registry. Proceed with all due caution because this potentially can create a number of other other problems. In fact, some people are decidedly against the use of any utility which claims to clean your registry. So I'm just telling you how I used to roll, in my Windows heyday. My preferred tool for this was also free and, in my experience, quite good. CCleaner [ http://www.piriform.com/download ] Good luck!

Ineffective OPTIMIZE TABLES
Hello all. I have an InnoDB table with a 'Data_length' of 114688 and 'Data_free' of '3896508416'. If I'm correctly understanding what I've been reading, those are good conditions to optimize the table. I understand the part where it maps to 'ALTER' for InnoDB.

I've done the 'FLUSH TABLES' for good measure and the results of 'SHOW TABLE STATUS' are unchanged.

I am new to MySQL coming from PostgreSQL noticed a really annoying issue. When I select a database, and try to auto complete in MySQL, it doesn't capitalize the MySQL statements. It's irritating to me to only be able to auto complete statements like 'SELECT', 'ALTER', 'INSERT' only if I hold down the shift key or caps lock key while typing. Is there a way to force MySQL to auto complete commonly used statements while typing them in lowercase which is normal behavior in PostgreSQL?

Query conditions
Hi all. I've got a greenhorn question but I didn't find the right keywords to get Google to answer it for me. Is it more efficient to put conditions in a JOIN instead of sticking them all at the end in the WHERE clause, or is that just a matter of preference? Putting conditions in the JOIN It seems, to me, to at least make the query easier to read. I was just curious if there were performance gains as well. Example: SELECT FROM table1 JOIN table2 ON this that WHERE that = '5'; vs SELECT FROM table1 JOIN table2 WHERE this that AND that = '5'; Thanks!

It seemed a little odd to me at first also, but I was told only that it was faster than any other method. It might make a little more sense if you realize that it isn't a script, it's just me listing the commands that are used. This process is on /my/ (development) environment, so hasn't the potential to make bad days for anybody except me.

Seems like an easy query, but isn't to me. Help?
I hope I've come to right place, and I'm asking in the right way -- please accept my apologies if not. We have some dates missing and I need to populate those fields with dates from the record just before them. I've gotten this far: SELECT UUid, MIN(DDenteredDate) minDate FROM UUtable JOIN DDdetail on DDid = UUid WHERE UUdate IS NULL GROUP BY UUid; I can make this a sub-query and get the UUid of the record that I want to copy UUdate from: SELECT sub.UUid-1 as previous, sub.* FROM ( SELECT UUid, MIN(DDenteredDate) minDate FROM UUtable JOIN DDdetail on DDid = UUid WHERE UUdate IS NULL GROUP BY UUid; ) as sub; In this case, the field 'previous' is the UUid that I want to copy the UUdate from and sub.UUid is where I want to copy to. Does that even make sense? Thanks, George

Re: learning mysql
I'm quite a distance from the best person to answer this question but MySQL has weekly webinars and there are a ton of good tutorials on the web. I started with WAMP (LAMP, MAMP and XAMP are suitable alternatives) and just started reading tutorials. Then I went to the local discount store and got a book about MySQL PHP. It wasn't the most recent but it was only a few dollars and the versions were new enough to not be problematic. I like Half.com for books. If you have trouble finding tutorials then leave a message and I'll comb through my bookmarks and see if I can find some that I used.
