MYSQL version differences

Hi

I am totally new to MySQL. Just wanted to know what are the major
differences between version 3.23 and version 4.0.26? Also would apps written
for 4.0.26 break on 3.23?

Thanks

Regards

I think you might start here:
http://dev.mysql.com/doc/refman/4.1/en/news-4-0-x.html

Unfortunately I have no short overview of important differences for you.

You should read the change logs starting on this page:
http://dev.mysql.com/doc/refman/4.1/en/news.html

That is, read "D.2 Changes in release 4.0.x" for the summary, and the
sub-sections for detailed information of changes per 4.0.x point-release.
Also would apps written for 4.0.26 break on 3.23?


In most cases MySQL 4.0 is backward-compatible with 3.23 at the application
level. I have had the experience of upgrading MySQL from 3.23 to 4.0,
without requiring any changes to the Perl web application on that server.

However, no one on a newsgroup can answer that question definitively with
regard to _your_ application (or any particular application). We don't know
what your application does, or which features of MySQL it employs.

Hi,

one concrete example that comes to my mind are UNION joins - if your
application uses them, it will run with 4.0 but not with 3.23. Also InnoDB
tables are not available in 3.23's standard versions (only with Max), so if
you use InnoDB table with 4.0, they will fall back to MyISAM if you move
them to a 3.23-standard server.

Hi folks, Yesterday I have upgraded my linux box with a pair of Xeon 1G CPU and reinstalled everything (it was a sinle Xeon 700). The default RH9 installation comes with MySQL 3.23.54.

(It's not very slow, but some lagging is noticed) I was running Mysql-max 4.0.11 and the performance was ok, except the slowness during the peak hours, which was regarded as...

the reason I ask is I have always used postgres at home and work, but my new web host only has mysql :( I want to know what sort of differences I will have in regards to programming php/perl webpages using the database. I current use sequences in postgres and understand this will be different in mysql, so can you tell me what the difference will be and if there are any other differences I should look out for.

Hi. I need to connect to MySql database in my .NET program. For that I'll use MySql.Data.dll, which is part of MySql Connector .NET. What are the main differences between version 1 and version 5? I tried both of them and the program runs fine in both cases. The version 5 dll file is almost two times as big as the version 1 file, but I don't know which one to choose.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
