RE: [PHP-DB] A newbie in deep need for help
Nope. Use this statement: $result = mysql_query($query2); The mysql_query() function actually performs the query to the db for you and returns a resource with your result set contained within. The mysql_result() function extracts the contents of a given cell from your result set; it does not actually execute the query to the db. Essentially you use mysql_result() to operate on a result set. Other things you can use on your result set include, but are not limited to: mysql_fetch_array(), mysql_fetch_row() and mysql_fetch_object, but again, they are operating on the result set retrieved by the mysql_query() function. Here's a good overview of the above functions: http://www.php.net/manual/en/function.mysql-result.php Hope this helps -Original Message- From: Ehab El Maraghy [mailto:[EMAIL PROTECTED]] Sent: Friday, December 27, 2002 4:17 AM To: [EMAIL PROTECTED] Subject: [PHP-DB] A newbie in deep need for help Hi everybody I have installed php4 and mysql on IIs winxp I am trying to retrieve a password and print it using a query which is written as followos $query2 = select passwd from user where username = '$username'; $result = mysql_result($query2); echo centerBOld Password was $result /B/center; am I using mysql_result right or is there another function to print this password taking in consideration that it just prints Old Password was and that's it -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

And shorter ones for this particular task. But this is kind of a general purpose set of statements that will usually do what you need. The mysql_query function sends the SQL query to the database and puts the data returned into a temporary table. mysql_fetch_array gets a row of data from the temporary table and puts it into an array that you can then process. The extract function creates separate variables from the array. If you are getting more than one row from the database, you can use the extract statement in a loop and process each row.

RE: [PHP-DB] A newbie in deep need for help
Yes, first you use: $result = mysql_result($query2); That will return something like resourceID #3. That's right. What you need to do now is to use a function to access the resource. For example, if you have a table named User with the following columns: ID username passwd and you want to perform a query that just returns the password, your code would look like something like this: $query2 = select passwd from user where username = '$username';//query $result = mysql_query($query2);//perform the query and return result set $thisPass = mysql_result($result);//return one column (passwd) from result set echop.$thisPass./p; //this line would just echo out the variable $thisPass to the browser to show you what it contains. Try that code and see if it works for you. If not, respond and paste all of the code you're working with and I'll see if I can find what's going wrong.
