SQL - Select doesn't retrieve results

Question

I\'m using sqlsrv_num_rows in order to check if a user exists in the DB.

When i\'m running the query in my DB i\'m getting 1 result, but in my PHP I\'m not

Answer 1

Explanations:

• Function sqlsrv_num_rows() requires a client-side, static, or keyset cursor, and will return false if you use a forward cursor or a dynamic cursor (the default cursor is forward cursor). Execute sqlsrv_query() with additional $options parameter and set the appropriate cursor type with "Scrollable" => SQLSRV_CURSOR_KEYSET
• Use parameterized statements. Function sqlsrv_query() does both statement preparation and statement execution and can be used to execute parameterized queries.
• If you want to check if the result set has one or more rows, you may use sqlsrv_has_rows().

Example, based on your code:

 SQLSRV_CURSOR_KEYSET);
$stmt = sqlsrv_query( $conn, $query, $params, $options);      
if ($exec === false){
    echo print_r( sqlsrv_errors()); 
    echo "
";
    return (false);
}

$count = sqlsrv_num_rows($stmt);
if ($count === false) {
    echo print_r( sqlsrv_errors()); 
    echo "
";
    return (false);
} else {
    echo "num: ".$count;
}
?>

Notes:

Do not send user credentials in plain text.
