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...

Hello,
Is there a way to specify MyISAM for all tables in a given file rather
than having to specify it at the end of each table declaration. I think
this would make porting databases back and forth to MySQL somewhat easier
since including MyISAM as part of the table declaration is not compatible
with standard SQL syntax, so I would like to keep MySQL-specific stuff
separate from the rest of the SQL DDL file.
Thanks,

Is there something like HotBackup for MySQL InnoDB tables, for MyISAM

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.

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
