Hi,
I'm looking at storing snippets of details in MySQL about what credit cards
a business excepts. Rather than have a whole column for Visa, another for
Amex etc ... I am looking at having a column called payment types and

Is this a good way of doing things? To me it'd be a lot cleaner and limit
amount of Db work to be done. Is this a sensible way in your opinion? What's
the best way of...

Hello,
Using PHP 4 and MySQL 4, how would I write a function such that it

when the form is posted if there were multiple tags in the post their
tagIDs are comma seperated before being inserted in the tagID column of
the Nodes table....

Hi. I am trying to select data from two separate MySQL tables, where I
cannot use join, but when I put the two select queries into a single
query, I get an error telling me to check my syntax. Both of the
queries work fine when I use them to query the MySQL server directly.
My guess is that the MySQL extension only expects a single resource
back from the database, but get's several, or that it just checks the
statement first, and decides...

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?

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,...
