How do we monitor that the connectivity between the rails app and the database is established. will rails try to re-connect the connection with mysql if it closes?
Hi,
I tried to search posts, but I only found solutions for SQL Server/Access. I need a solution to MYSQL (5.X).
I have a table with 3 columns: hostid, itemname, itemvalue. If I do a select, it will return
1 A 10
1 B 3
2 A 9
2 C 40
How do I query the database to return something like
A B C
1 10 3
2 9 40
Hi Guys,
I need to work out a period of 6 months (backwards) from a given date.
Example date:
07/06/2010 00:00:00
needs to count back 6 months and display:
07/12/2009 00:00:00
I have been scanning through: http://dev.mysql.com/doc/refman/5.1/en/date-and-time-functions.html and non of these functions make sense to me :(
Hope this makes sense and any help would be appriciated.

i have adjusted my code slightly but i am still having difficulty posting it to the table. could someone please provide me with an example of the foreach array?
form page
<div style="padding: 15px;">

<?php include("progress_insertcomment.php"); ?>
<?php
// Make a MySQL Connection
mysql_select_db("speedycm_data") or die(mysql_error());
$query_comment = "select * from tbl_alert order by id desc limit 1";
$comment = mysql_query($query_comment, $speedycms) or die(mysql_error());
$row_comment = mysql_fetch_assoc($comment);
$totalRows_comment = mysql_num_rows($comment);
?>
<!--- add notification --->
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<span id="sprytextarea1">
<textarea id='comment' name="comment" style="height: 75px; width:330px;"><?php echo $row_comment['comment']; ?></textarea>

</form>
</div>
</body>
processing
<?php
// 6) update notifications
if (array_key_exists('notc2',$_POST)) {
echo "<p style='font-size: 12px;'>Thank you. The notifications have been updated successfully.<p>";
echo "<p><span style='font-size: 12px;'>
<a onClick=\"history.go(-1)\" class='form'>Return</a></p>
<p></span>
";
exit;
};
?>
after doing some research i learnt that the only way to insert multiple radio values into the MYSQL table is to use arrays. there was a similar question raised somewhere on this site: http://stackoverflow.com/questions/1656260/php-multiple-radio-buttons that recommended using a foreach loop.
use a foreach loop
<?php
foreach ( $_POST as $key => $val )
echo "$key -> $val\n";
?>
$key will be the name of the selected option and $val, well, the value.
how would this apply to my situation as i am struggling to find any help on the internet. i understand that i would use this on the processing page to pull out any radio values from the previous page and then loop the INSERT MYSQL code within the process until it was all done.
any advice would be appreciated! GOD BLESS.

I have a table called 'highscores' that looks like this.
id udid name score
1 1111 Mike 200
2 3333 Joe 300
3 4444 Billy 50
4 0000 Loser 10
5 DDDD Face 400
Given a specific udid, I want to return the rank of that row by their score value.
i.e. if udid given = 0000, I should return 5.

I have a mysql database with 60 tables most of the tables have primary keys (expect pivot tables) all these primary keys had the attribute AUTO INCREMENT
Then over night some how all the primary keys had that attribute removed, and the default value set to 0.
I have no idea how this may have been caused. Any suggestions?
For some reason, the developers at a new company I'm working for decided to name their columns "ignore" and "exists". Now when I run MySQL queries with those words in the where clause, I get a syntax error; however, I can't seem to figure out how to reference those columns without running into an error. I tried setting them as strings, but that doesn't make any sense.
Help?
Also, is there a term for this kind of mismatch?
I have two tables, with the same structure, for example: table "first' with columns 'a','b','c' and table 'second' with the same columns. How to find difference betweet those two tables?

Hi Folks,
I have some data in one of my mysql table stored as utf8. The data is some japanese text. I need to export it to excel. Could you tell how to do it?
Exporting by SELECT ... INTO OUTFILE returns some plain text file. I'm not sure how to read it back in excel so that japanese character would show properly
Thanks

Is it possible to do this with MySQL query, without using php script?
Is there any way, i can use 'Load data infile' in a stored procedure.
I am using mysql.
LOAD DATA LOCAL INFILE 'C:\\MyData.txt' INTO TABLE
tempprod fields terminated by ',' lines terminated by '\r\n';
SELECT * FROM product p;
User writes a series of tags (, separated) and posts the form.
I build an array containing the tags and delete dupes with array_unique() php function.
I'm thinking of doing:
go through the array with foreach($newarray as $item) { ... }
check each $item for existence in the tags mySQL table
if item does not exists, insert into tags table
Is there a FASTER or MORE OPTIMUM way for doing this?
Is it possible to restore a MySQL database from the physical database files. I have a directory that has the following file types:

I have a MySQL database with a field Name which contains full names. To select all people with last names starting with a particular letter, let's say A for this example, I use the following query: SELECT * FROM db WHERE Name LIKE '% A%'. However, this also selects users who have a middle name starting with A. Is there anyway to alter this query so that only a last name starting in A will be selected?
Seems like max table comments length in mysql is only 60 characters.
I'm developing an aplicacion in php symfony, which automatically generates sql ddl sentences, and in many cases those comments are far beyond 60 characters.
Is there some way to increase that limit?
thanks a lot
This one is really puzzling. I can't seem to be able to run any prepared statement on MySql 5.1. Any simple select I'm writing runs fine but when I'm trying to run it from a prepared statement I'm getting Query returned no result set. What Am I doing wrong?
Exmaple:
prepare s from 'select * from t';
execute s;
Thanks!
