I've searched Google every way I know how, and came up with two answers that
refer to MAX_KEY and MI_MAX_KEY, along with a typedef for key_map.
I have the 4.1.1 alpha source (4.0 is no good, because it doesn't support
subqueries).
I changed the two defines in sql/mysql_priv.h and include/myisam.h,
respectively. The typedef for key_map is no longer ulong or ulonglong, but
instead Bitmap(64);

I made a MyISAM table on mysql 4.0.18 NT with auto_increment column
started at 2147483646. The third row I insert fails as expected
because the integer range is maxed out. However, if I delete the
topmost row, and then re-insert a row, the topmost value is reused.
This contradicts the documentation.

AUTO_INCREMENT column, the...

Retracing my problem leads me to believe I never successfully created
fulltext indexes for MySQL 3.23.58 MyISAM tables. I went to the MySQL
manual and was able - or so I thought - to create them, however, my
fulltext search queries fail in 3.23.58 but the exact queries (with
same data) work perfectly in 4.0.10.

I'm working in a project in C++ using MySQL C API (Win98/Dev-C++

to setup the server environment language (--language) via
mysql_options() function.

you start with a small application in access97, then you have more
modules and more...
and you reach the point where tables like 'item' and 'employee' reach
the limit and you
know there's more indexes required for RI to come
does creating a RI programatically instead of the relationship window
still consume one of the 32 indexes ?
does access2000 / 2003 allow more indexes per table ?

Hi,
is it possible that due to OS crash or mysql itself crash or some e.g.
SCSI failure to lose all the data stored in the table (let's say million
of 1KB rows). In other words what is the worst case scenario for MyISAM
backend?
Also is it possible to not to lose data but get them corrupted?

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:

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,...
