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 wondering if there is a way to retrieve Foreign Key declaration
information on both MyISAM and InnoDB tables.
Of course, I understand that MyISAM doesn't support Foreign Keys,
however, it does still parse FK declarations within a CREATE TABLE
statement, and moreover, it even creates an index on the column that
is the Foreign Key.
So my question is for this sample CREATE TABLE declaration:

Some one suggested me to alter my tables to InnoDB instead of myISAM
type to improve speed for select queries. Is this really true. I read
some article that stated that myISAM was optimized for select queries
over update/insert because of most of the queries for web based
applications are select queries.
Can anyone tell me what the advantages or disadvantegs are of InnoDB
over myISAM?
Is there anythging I should keep in mind when I...

Hi,
Besides transaction capability, is there anything else about innodb
tables that makes it superior to myISAM?
I really don’t need transactions, but for example, I need superior
reliability for index (too many index corruptions in the past). Is
innodb better in that area, or any other areas?

Hi!
I'm working in a project in C++ using MySQL C API (Win98/Dev-C++
4.9.9.8/MySQL DevPak/MySQL 4.1.13) and I want to know if it's possible
to setup the server environment language (--language) via

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...

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
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.
