issues with select statement

Hi,

I am doing a project with dreamweaver and i ran into a hitch with my select statement.

I have this

 

SELECT *
   FROM client, `statement`
   WHERE client.client_id = `statement`.client_id 

 

when i execute this it selects everybody in the database. So i want to add another WHERE statement to this query, this time one that compares the client.username with the session variable "MM_Username".

Thank you in anticipation of solving this for me!

So I am looking at something like this

 

SELECT *
   FROM client, `statement`
   WHERE client.client_id = `statement`.client_id  AND WHERE client.username = '$_SESSION['MM_Username']'

 

The session php code is as follows

 

 

 

<?php
   if (!isset($_SESSION)) {
  session_start();
   }
   $MM_authorizedUsers = "";
   $MM_donotCheckaccess = "true";

   // *** Restrict Access To Page: Grant or deny access to this page
   function isAuthorized($strUsers, $strGroups, $UserName, $UserGroup) {
  // For security, start by assuming the visitor is NOT authorized.
  $isValid = False;

  // When a visitor has logged into this site, the Session variable MM_Username set equal to their username.
  // Therefore, we know that a user is NOT logged in if that Session variable is blank.
  if (!empty($UserName)) {
    // Besides being logged in, you may restrict access to only certain users based on an ID established when they login.
    // Parse the strings into arrays.
    $arrUsers = Explode(",", $strUsers);
    $arrGroups = Explode(",", $strGroups);
    if (in_array($UserName, $arrUsers)) {
	  $isValid = true;
    }
    // Or, you may restrict access to only certain users based on their username.
    if (in_array($UserGroup, $arrGroups)) {
	  $isValid = true;
    }
    if (($strUsers == "") && true) {
	  $isValid = true;
    }
  }
  return $isValid;
   }

   $MM_restrictGoTo = "myflog.php";
   if (!((isset($_SESSION['MM_Username'])) && (isAuthorized("",$MM_authorizedUsers, $_SESSION['MM_Username'], $_SESSION['MM_UserGroup'])))) {   
  $MM_qsChar = "?";
  $MM_referrer = $_SERVER['PHP_SELF'];
  if (strpos($MM_restrictGoTo, "?")) $MM_qsChar = "&";
  if (isset($_SERVER['QUERY_STRING']) && strlen($_SERVER['QUERY_STRING']) > 0)
  $MM_referrer .= "?" . $_SERVER['QUERY_STRING'];
  $MM_restrictGoTo = $MM_restrictGoTo. $MM_qsChar . "accesscheck=" . urlencode($MM_referrer);
  header("Location: ". $MM_restrictGoTo);
  exit;
   }
   ?>

You've not highlighted any problems your having. Just said what you want to do and you already seem to be on the right track to do it so what's the problem?

 

You're current SQL statement can also generate ambiguity. Change it to a join like:

 

SELECT *
FROM `client`
JOIN `statement` ON `statement`.`client_id` = `client`.`client_id`
WHERE `client`.`username` = ':username'
