You can type "show create table " to see the datatypes. Waynn On 2/13/09, James Colannino wrote: > Hey everyone.

Re: [PHP] help with mysql query / logic
Can you perhaps post the structure of your tables? That would make it easier to help (at least for me) On Thu, 2002-10-10 at 15:40, Pablo Oliva wrote: > I have 2 tables, one with job ad information, and a second one with the > locations that this ad applies to. > > When a person queries the job ad table with their criteria, I would also > have to query the location table to see if the location that they chose > applies to this ad.

RE: Re: [PHP] Help with MySQL.
I'm sorry after re-reading the correct answer would be this:
The hostname(ip address) of the mysql box is whatever you telnet too, if
indeed you get those weird characters when you 'telnet localhost 3306'.
For instance if you telnet to 192.168.0.1, that is the mysql server address.
If you telnet to 'server1.myisp.com' or 'server1' that is the address.
The hostname and ip address are very much interchangeable, though as a
general rule of thumb, ip address is more reliable.

For one of my servers I get " 3.23.34-log3REu?zk*+;,"

That means that is most certainly running on it, if not you would get
something like "Telnet: Unable to connect to remote host: Connection
refused"
Be warned, if your isp does not know anything about their mysql server, they
may not know the password.

Dan,
What do you mean by :
If you get some weird characters(most likely the version and some other
chars) then the server is itself, is the mysql host.
Because thats what happens. Thanks,

RE: [PHP] Help with MySQL.
Once in your telnet session, from the command line type 'telnet localhost 3306' or 'telnet 127.0.0.1 3306' Keep in mind this only proves the host is there, it doesn't disprove. The machine may not know itself as localhost(unlikely) or the mysql server may not be living on 3306. If you get some weird characters(most likely the version and some other chars) then the server is itself, is the mysql host.

Hello everyone, I need some help with telneting to my web host and figuring out what the host name address is to mysql. My web host (which is my ISP) knows that they have MySQL but they don't know the host name address. I want to know if there is a sentence I can type into the telnet box to see what my MySQL host name address is? I tried 'whereis mysql' and it came back 'mysql: /usr/bin/mysql /usr/lib/mysql /usr/share/mysql /usr/man/man1/mysql.1.gz' so I know I have it, but whats the host name address?

Re: [PHP] Help with mysql query
Daniel, Try this. Still sort of a brute force method but just 10 query strings instead of 50 but nothing MySQL is going to balk at. Then you an print out the results stored in the $num_vals list using a similar for loop. -Kevin Stone - Original Message - From: "Daniel Alsén" <[EMAIL PROTECTED]> To: "PHP" <[EMAIL PROTECTED]> Sent: Tuesday, December 11, 2001 4:09 PM Subject: [PHP] Help with mysql query > Even if this isn´t a mysql forum i hope to get some help on this: > > I have a table with 5 columns (named one to five) which contains numerical > values between 1 and 10. > I am trying to construct a query that gives me the count of the > representation of each numerical value (ie how many fives that are stored). > > Can i do this in a smart way without having to write fifty queries and add > every fifth of them up? > > Regards > # Daniel Alsén| www.mindbash.com # > # [EMAIL PROTECTED] | +46 704 86 14 92 # > # ICQ: 63006462 | +46 8 694 82 22 # > # PGP: http://www.mindbash.com/pgp/ # > > > -- > PHP General Mailing List (http://www.php.net/) > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > To contact the list administrators, e-mail: [EMAIL PROTECTED] > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
