Hello,
I recently converted all my existing MyISAM tables to InnoDB tables
through phpmyadmin. I noticed some strange behavior whenever I would
refresh the screen, as phpmyadmin would report different numbers for the
cardinality of the primary key (i.e. one minute it would say cardinality
388, then 244 on refresh, then something else), and it would report
different values for the number of rows when mousing over the table
names on the...

Is there something like HotBackup for MySQL InnoDB tables, for MyISAM
tables? I'm using MyISAM tables for some of my tables because I needed
FullText search.

I want to use constraints, so I will have to use innodb tables (according to
the website mysql.com).
But, what is the difference between myisam and innodb tables ??
And why is there a comment "innodb free: 4096 kb" since I have changed my
tables from myisam to innodb?
Is this working like Sybase, where you need to create devices for data
storage, or do I miss the idea completely here?
Please notice, I am a beginner, so please be patient.

I'm new to databases and am experimenting with mysql.
I have a clients table and a sales table in a mysql database.
Client_id is the primary key in clients and a secondary key in sales.
The only client_id's that show up in the clients table are client_id's
starting at 28 (they autoincrement from there). 1-27 were old ones
that I used in testing. I added a new client and clients shows the new
client_id as 188 which makes sense. I added...

Hi there
I have a database with about 20 or so tables, maybe a few thousand rows
in each. I am starting to do more complex things with my insertions etc,
and I want to start to use transactions, so I imagine I should change
some table types in the database from MyISAM to InnoDB.
I know that InnoDB tables are a completely different beast than MyISAM in
terms of data storage etc... ie: instead of using folders on the server,
everything...

I am using mysql-4.0.24 on a Windows2000 machine for a small but complicated application. A few times I've experienced corruption of tables. Most of the times the error was -"can't open file: 'tableName.MYI'. (errno: 144)".
I've read somewhere that using CHECKSUM = 1 can reduce the chances of corruption in MYISAM tables. Is it correct? Will it affect the insert/update timing and query performance?

Hello
I use a table to cache some informations which need lots of resources to
be composed. The first time the info is needed, it will be composed and
written to the cache table ($db in the example is a PEAR DB object; the
question is the same for other ways of accessing the database):
// Retrieve info if present
$details = $db->getOne("SELECT contents FROM cache WHERE id=".$id." AND
info='details'");

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

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,...
