Re: MySQL-php UPDATE errors
Hi,
Try
$saveQuery = UPDATE $table_product SET PROD_PRICE =
'$value' WHERE PROD_ID = '$key';
instead of
$saveQuery = UPDATE $table_product SET PROD_PRICE =
\$value\ WHERE PROD_ID = \$key\;

Hi guys,
Hope you can help. I'll give you the source code for my
overwriteProduct.php3 first I think:
?php
if (count($DBHOST)==0)
include(/home/stud/yrf/bsccs4/c9803057/phpincludes/dbFunctions.php3);
$dbcnx = myConnect();
echo 1;
while (list ($key, $value) = each ($PROD_PRICE))
{
echo 3;
$saveQuery = UPDATE $table_product SET PROD_PRICE =
\$value\ WHERE PROD_ID = \$key\;
$result=mysql_query($saveQuery);
echo 4;
if (! $result) printf (Error: %s
, mysql_error ());
};
?
This gives the following errors when I run the thing:
134Error: You have an error in your SQL syntax near 'SET PROD_PRICE = 222
WHERE PROD_ID = 1' at line 1
34Error: You have an error in your SQL syntax near 'SET PROD_PRICE = 444
WHERE PROD_ID = 2' at line 1
34Error: You have an error in your SQL syntax near 'SET PROD_PRICE = 789
WHERE PROD_ID = 3' at line 1
34Error: You have an error in your SQL syntax near 'SET PROD_PRICE = 321
WHERE PROD_ID = 4' at line 1
The numbers I'm setting the column/row combos to are spot on ($value $key
are fine). Anyone got an idea why it's not working?
Thanks in advance.

Re: char - varchar ?
Hi, Char columns are used with fixed-length type table, whereas varchar are used with dynamic table. If you have varchar columns in your table, all char columns will be convert to varchar column (you can't have a fixed-length table if your table contain varchar, blob or text field). Here are the property of static table : All CHAR, NUMERIC, and DECIMAL columns are space-padded to the column width. Very quick. Easy to cache. Easy to reconstruct after a crash, because records are located in fixed positions. Doesn't have to be reorganized (with myisamchk) unless a huge number of records are deleted and you want to return free disk space to the operating system. Usually requires more disk space than dynamic tables.

REPLACE DELAYED bug with MySQL 3.23.36
Hi !
I notice a bug with MySQL 3.23.36 with REPLACE DELAYED which crash my MyISAM
tables.
The problem was present in MySQL 3.23.34, but not in 3.23.33 nor 3.23.35.
The bug occurs randomly and makes MySQL restart...
With REPLACE instead of REPLACE DELAYED, there seems to be no problem.
Here is what MyISAMCHK report :
Checking MyISAM file: online
Data records: 96 Deleted blocks: 79
myisamchk: warning: Table is marked as crashed
- check file-size
- check key delete-chain
- check record delete-chain
myisamchk: error: record delete-link-chain corrupted
- check index reference
- check data record references index: 1
myisamchk: error: Found key at page 2048 that points to record outside
datafile
MyISAM-table 'online' is corrupted
Here is what I use with PHP :
mysql_query("REPLACE DELAYED INTO online (pseudo,date,cat,forum) VALUES
('$user','$time','$cat','$site')",$dbh) or die( "Erreur 1:".mysql_error());
}
else
{
mysql_query("REPLACE DELAYED INTO guest (pseudo,date,forum) VALUES
('$REMOTE_ADDR','$time','$site')",$dbh) or die( "Erreur:".mysql_error());
}
$timeold=$time-120;
@mysql_query("DELETE FROM online WHERE date $timeold",$dbh) or die(
"Erreur:".mysql_error());
@mysql_query("DELETE FROM guest WHERE date $timeold",$dbh) or die(
"Erreur:".mysql_error());
Now the online and guest table structure :
CREATE TABLE online (pseudo char(35) NOT NULL,date int(11) unsigned DEFAULT
'0' NOT NULL,cat tinyint(4) unsigned DEFAULT '0' NOT NULL,forum char(35) NOT
NULL,PRIMARY KEY (pseudo),KEY date (date));
CREATE TABLE guest (pseudo char(35) NOT NULL,date int(11) unsigned DEFAULT
'0' NOT NULL,forum char(35) NOT NULL,PRIMARY KEY (pseudo),KEY date (date));
If I have time I'll try to make a stack trace report...
