Hello,
Try this

{
$hostname = localhost;
$username = joe;
$password = user;
$dbName = test;
$link = @mysql_pconnect($hostname, $username, $password);

Further to this, I removed the @ symbol and got:-
Fatal Error: Call to undefined function: mysql_connect() in
/var/www/html/results.php
@ $db = mysql_pconnect(localhost, user, password);
$db = mysql_pconnect(localhost, user, password);
Ideas ? Why is it now a undefined function ?

Re: Encrpt/Decrypt
Just want to add a few more things here that might spark your brain cells. All in all I agree with the suggestions presented. Use an encrypt function in your code, for something simple I've created a very basic encryption function in perl using Crypt::Blowfish modules and then I have control of the key to encrypt and decrypt it. Then you can process your request over SSL (if possible) just run the script over https if supported and then store the encrypted value in the database as a string. I think you can even run SSL on MySQL so that you can secure your connections further especially if you're replication your database etc. The MD5() function in PHP might also do the trick for you. http://www.php.net/manual/en/function.md5.php Good luck JM Gregory Junker wrote: and it's all-around better to encrypt the password BEFORE you transmit it over an unsecure connection, or even between processes on a potentially unsecure machine.

Authentication is done by taking the password provided, encrypting it, then comparing against the encrypted key in the database.

Re: Math Computations
I agree with the suggestion below strip the character and typecast it if
necessary. In JSP I think you can convert it to a number and then typecast it.
In PHP, I think the principles might be the same.
In addition, it might be a good idea to restrict the columns that require
computation to a numeric value rather than a string because you can always add
the comma later when totalling it for display. It might also be more efficient
for sorting and doing sums, totals etc from your select statements.(i.e. select
sum() total()) since computers are inherently better at handling numbers than
strings (though I could be mistaken)
So if its possible for you to redeclare the table definition then that will be
great.
Good luck

Hi All,
How do I make calculations in php or mysql if the value has a comma
like
2,000 + 32,000 = 34,000. I have a problem
calculating if one of my values has a comma. It doesn't display the
right
output. I'll appreciate anyone who can
help me with this.
Thanks.
Delz.

Something like
?
$db = mysql_connect(localhost,database_user,password);
mysql_select_db (database_name);
$query = SELECT * FROM table_name;
$result = mysql_query($query);
echo Computers | Department | Price Per PC | Total Amountbr;
while ($row = mysql_fetch_row($result)){
$subtotal=$row[0]*$row[2];
$total+=$subtotal;
echo $row[0] | $row[1] | $row[2] | $subtotalBR;
$comptotal+=$row[0];}
}
echo $comptotal $total;
?
Obviously format it into a table would make sense, e.t.c.

Re: mysql+jdbc+international character support
Hello, Thank you for your immediate reply. What database version have you used these drivers for? Do you have a preference for either? Thanks again. jm TAKAHASHI, Tomohiro wrote: Hi, Both gweMySQL and MM.MYSQL support Unicode-Nativecode conversion.

We need to setup a database that is capable of handling international characters similar to Oracle. We plan to use MySQL and the latest JDBC drivers for MySQL. I've searched Google to see if MySQL has dedicated support for international characters but was less than satisfied with the results. So the question is: What version (if any) does MySQL support international characters? Does the latest JDBC driver support this as well? If it does support it are there resources that perhaps you can recommend that I can read up on? If it does not support international characters are there plans to in the next few releases?
