RE: Serious error in update Mysql 4.1.7
Hi Luciano, Not that this reply will solve your problem, but let it serve as a notice. It is NEVER a good idea to use a FLOAT/BLOB column in your where clause as MySQL can not uniquely identify the record. Especially not with floats because of the inherent floating point error made between machines after a specific number of decimals (which depends on the hardware on which the MySQL is running). To clarify: select MyFloat from MyTable; Machine A might result in: 0.123456789012345[987345765] Machine B, using exactly the same MySQL version with exactly the same table and data: 0.123456789012345[765365423] Because of precision floating point errors (in the sample, after the 15th decimal) the values in the square brackets will differ and effectively be random numbers. You can thus see the problem in asking MySQL to match floating point data using a WHERE clause. In fact you can do the same query twice on the same machine and MySQL won't be able to locate the record as the ultimate float value will differ twice in a row. Always remember computers are binary machines which loves integers. After filling the internal 8 bytes with a floating value, the rest of any floating value precision becomes a toss up. Another sample (MySQL 4.1.7): mysql> select pi(); +--+ | PI() | +--+ | 3.141593 | +--+ 1 row in set (0.00 sec) mysql> select pi()=3.141593; +---+ | pi()=3.141593 | +---+ | 0 | +---+ 1 row in set (0.00 sec) If the sample you gave was auto-generated by the MyODBC driver it most likely compiled the WHERE clause because you don't have an unique primary key in your table. Best advise is to always add a primary key AUTOINC column to all tables. This will not only result in all your queries always being able to find the exact record, but will also reduce the traffic your current queries cause. The addition of an AUTOINC column is mainly due to MySQL's lack of server side cursors. This will be corrected it seems in MySQL 5, after which everyone will always be able to find their records independent of the data contained in the table.

I haven't been following this, but I can make a good guess. Some email clients can thread messages - my client (KMail) is one of them. If you hit reply, your message gets placed in the thread that you replied to. It is *NOT* based on the subject, it uses the "In-Reply-To" header. If you enter a new message, it begins a new thread. If it is really a new message, it is out of context to put it into an existing thread. If it is really a reply, it may be lost in a new thread. Because of threaded emails, it is considered bad practice to start new threads by a reply - or use "New" to reply to a thread. I won't claim I've never done it, but it is bad practice. -BEGIN PGP SIGNATURE- Version: GnuPG v1.2.4 (GNU/Linux) iD8DBQFBZC6mjeziQOokQnARAp5wAJ9QehvPkNRVwKGgUkAjAm7jkQfRowCgrWaH BwWO1G8aButW0ejjh3P2O4w= =EkBR -END PGP SIGNATURE- -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

works:
self.dbh.execute("INSERT INTO Foo (blah, blorg,snork) VALUES
(%s,%s,%s)",myList)
... But this kind doesn't appear to work for me:
self.dbh.execute("UPDATE Foo SET blah=%s, blorg=%s WHERE snork=%s",myList)
Doing the latter with a loop in Python is much slower than I'd expect that
doing it with a list would be.

Re: After php udate, php pages no longer update MySQL database
Hi. That's too few information to say anything concrete. Do you get any error message? If not, please look how to enable error messages in PHP (or change your script to log them). Then post the error message you get. Bye, Benjamin.

RE: After php udate, php pages no longer update MySQL database
Sorry but questons
What is the update.log say (is it connecting)?
Is it just UPDATE, do SELECT's work?
Have you got
if (mysql_create_db ($DBname, $Link)){
print ("worked");
}else{
print ("fail");
}
etc...?

Cannot UPDATE mysql record in ASP
I get this error when trying to update a record using ASP recordsets.
Microsoft OLE DB Provider for ODBC Drivers error '80040e21'
Multiple-step OLE DB operation generated errors. Check each OLE DB status
value, if available. No work was done.
/Web_local/admin/xt_save.asp, line 39
What is really strange is that the line # is referencing a line where I
assign a value to a field see code below the line is marked with asterisk.
Sub Update()
Set rs = Server.CreateObject("ADODB.Recordset")
sSql = "select * from table where ID="&ID
rs.Open sSql,aCn,3,3
*-->rs("DESCRIPTION") = strDesc
rs("DETAILS") = strDetails
rs("LAST_MODIFIED_DATE")= Now()
rs("ACTIVE_FLAG") = "1"
rs.Update
rs.Close
Set rs = Nothing
End Sub
I tried a bunch of different things and I always get his error, any clue on
what is going on! BTW, this is my first system using MySQL as a back end.

The first example looks a bit suspect unless $field_str holds a set clause in the form: column_name=expression, and further that "expression" does NOT contain double quotes, eg a string value's delimiters. You should precede these with several function calls to 'open' the db, and should follow every mysql_...() call with an error check. Prevailing wisdom suggests putting an echo between the two lines, so that you can see exactly what will be passed as the query to MySQL. Finally, if there is any question, that output can be copied-and-pasted into a command line query or a MySQL administration tool to verify/confirm the SQL syntax.

Update MYSQL command with PHP
Question is there something wrong with this syntax when using the MYSQL Update command in PHP , where I change the record by users editing the fields on a web form then those are extracted to update a record in a table. Here's what I have tried I don't get any syntax errors with either of these attempts $query1 = "UPDATE Qusers SET $field_str WHERE UserName='$username'"; $result2 = mysql_query($query1); Second Example $query1 = "UPDATE Qusers SET BillAmt='$billamt' WHERE UserName='".$username."' AND Qusers.RID ='".$keyid."'"; $result2 = mysql_query($query1); Kory Wheatley - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?

It depends on which version you have already installed. Do you use RPMs or source code? And, which version of MySQL do you have?

[beginner] How to update mysql with Linux ?
Hi all, I'd like to update my version of Mysql on linux. How can I do it so that I don't have two copies of mysql on my machine ? Do I have to clean up the folder "mysql" and then install the new version under it? And what should I download -the source code or the binaries- in order to update the starting scripts under /etc/rc.d/init.d ? Thanks a lot Francesco [EMAIL PROTECTED]
