A query with a join as such


$sql = "SELECT * FROM tableA
		LEFT JOIN tableB ON (tableA.customerid=tableB .Id)";
 
//---prepare query above
$stmt=sqlsrv_query( $conn, $sql, $params, array( "Scrollable" => 'keyset' ));

Open in new window


in a loop where this drives it

while ($row = sqlsrv_fetch_array($stmt)){ 

 

Open in new window


trying to pull the Id which both tableA and tableB have

  
$Id=$row[Id];

Open in new window

Gets only tableA's Id of course, I need both Ids

I am used to MySQL/PHP where I can specify as

$IdA=$row[tableA.Id];
$IdB=$row[tableB.Id];

Open in new window


but I am having now luck

Try to use alias for ID's.

For example:

$sql = "SELECT tableA.id as IdA, tableB.id as IdB, * FROM tableA
            LEFT JOIN tableB ON (tableA.customerid=tableB.Id)";

Then you can get IDs

$IdA=$row[IdA];
$IdB=$row[IdB];

To understand why this is an antipractice, please read about the use of quotes in PHP.

$IdA=$row[IdA]; // What is the defined constant named IdA?

Ray,

I pay for this service for quick solutions.  While an article on the foundations of PHP is a good resource, it is not a solution.  In this context, it is simply link bait to get me to read your article.

link bait
Ha!  That might make sense if I get paid when you read my articles.  Like I said, "Best of luck..."
