Dear MySQL developers,
Could some experienced Database developer please take a look at this ?

How can it be coded under MySQL
Especially all referential triggered actions.

Hi,
I'm somewhat new to MySql. I've been using it for a while, but pretty much
out of the box setup, and am starting to suffer heavily with my larger
tables. I have a table with 5,000,000+ rows that I have to search and do
joins on. Although I have an index set up for it, the joined select will
still take some 400+ seconds to return, which is obviously unacceptable.
This is due to enormous HD access.
Perhaps someone can help me...

Hi all,
I ran the myisamchk tool with the options --sort-index
--sort-records=1 against an MYI file. Is there something I can use to
confirm what this command did? I would like to see what the sort order
on the disk for each table in my database.
I am using MySQL 4.0.20a-nt running on a Windows 2000 box.
Thanks in advance

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:

I'm running MySQL 4.1 under Linux. I need to have a MyISAM table with
more than 4G rows of data.
I've read the manual regarding the MAX_ROWS option on tables. This
table has a fixed row length, with 17 bytes per row.
MySQL simply won't set the ROW_LENGTH greater than 4G. When I use an
ALTER TABLE to set it higher, it acts as though it worked fine, but a SHOW
TABLE STATUS indicates that it is still limited to 4294967295.

How do I sort a table, from a form. I can't use SQL!
WE have an Access application that is created by an outside vendor. The
one form states: "Please make sure all records in table are sorted by
date..."
The application is not locked or hidden in any way, but is fairly
involved. I would like to be able to simply add a button to this form
to sort the table.

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?

hi,
I found a jquery html table sorting code i have implemented. I am trying to figure out how to edit how many colums there are, but every time i remove code that I think controls how many colums there are, it crashes.
There are currently 6 columns, and I only want 4. How do I remove the last two (discount and date)?

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,...
