I know up to eight Bit fields are merged into one byte to save space, but what if I have a couple of Bit fields and an Enum or a Set field? Are they internally merged too? I'm asking because I'm going to have a lot of rows in my table and I want to avoid overhead as much as possible.

...AND column=''...
and that doesn't return any results at all. I've ...
Hello,
I try to connect mysql via PHPMYADMIN, using my password, but it can't stop telling me that (access denied, using password NO) but i'm using a password :O
When i connect via the console with my password, it works but not on phpmyadmin.
It's really weird.
Do you have an idea to fix that ?
edit: it worked couple of days ago, b...
I'm looking for an ETL solution that we can create a configure by hand and then deploy to run autonomously. This is basic transformation, it need not be feature heavy. Key points would be free or open source'ed software that could be tailored more to suit specific needs.
In fact, this could be reduced to a simple DB migration tool that ...
Please don't send me a link to php.net referencing mysql_real_escape_string as the only response. I have read through the page and while I understand the general concepts, I am having some trouble based on how my INSERT statement is currently built.

Should we store the datetime field as a mysql datetime. Or should be break it up i...

I am using the insert() function from Zend_Db_Table_Abstract.
The data being inserted is user input, so naturally I am curious if ZF does the data cleansing for me, or if I should do it myself before I call the insert() function.

Hi
i have an mysql database with some sports results in it. I want to write an android application to display these data on mobile phones.
I´ve searched on the internet for this issue and i think it is not possible to have a direct connection between the mysql database and the android application. (Is this right?)

I find it incredibly annoying to write a using statement on every one of my queries (which require its own command or write parameters.clear()) which sometimes require declaring variables outside of the using block. Its so incredibly annoying and looks much dirtier compared to the version without disposing the object.
Do i need to dispo...
I've a database used to store items and properties about these items. The number of properties is extensible, thus there is a join table to store each property associated to an item value.

`property_id` int(11) NOT NULL,
`item_id` int(11) NOT NULL,
`value` double NOT NULL,

The problem was related to the number of concurrent connections : only five.
The result is that my web app doesn't crash. I didn't notice any poor performance after disabling it.
Are there any "collateral" or side effects to disabling con...

I've been working with some long lists of information and I've come up with a good way to post it in various formats on my wordpress blog posts.
I installed the exec-PHP plugin, which allows you to run php in posts. I then created a new table (NEWTABLE) in my wordpress database and filled that table with names, scores, and other stuff....
Hi all,
I have difficulty especially in installing MySQLdb module (MySQL-python-1.2.3c1), to connect to the MySQL in MAMP stack.
I've done a number of things such as copying the mysql include directory and library (including plugin) from a fresh installation of mysql (version 5.1.47) to the one inside MAMP (version 5.1.37).

I'm currently running a query like this:
SELECT *
FROM email
WHERE email_address LIKE 'ajones@%'
OR email_address LIKE 'bsmith@%'
OR email_address LIKE 'cjohnson@%'
The large number of OR's bothers me. Is there a way to condense this up with something akin to an IN operator, e.g.:
SELECT *
FROM email
WHERE email_addres...
