How to add parameter to clause in PDO query - php

Question

I am using code to run a Mysql query that defines a clasue ($datimeClause). I would like to run the query with a second parameter (:method) but if I change the syntax of the clause at all, the query won't run. I am fairly new to PDO could someone please tell me how I can reformat the clause to query for the second parameter.
This is the Query
public static function getList( $numRows=1000000, $datimeId=null ) {
$conn = new PDO( DB_DSN, DB_USERNAME, DB_PASSWORD );
$datimeClause = $datimeId ? "WHERE DatimeId = :datimeId" : "";
$sql = "SELECT SQL_CALC_FOUND_ROWS * FROM notify $datimeClause";
$st = $conn->prepare( $sql );
$st->bindValue( ":numRows", $numRows, PDO::PARAM_INT );
$st->bindValue( ":datimeId", $datimeId, PDO::PARAM_INT );
$st->execute();
$list = array();
while ( $row = $st->fetch() ) {
$text = new Text( $row );
$list[] = $text;
}
This is the function that calls it.
function newAutoText() {
$results = array();
$datimeId = ( isset( $_GET['datimeId'] ) && $_GET['datimeId'] ) ? (int)$_GET['datimeId'] : null;
$results['datime'] = Text::getById( $datimeId );
$data = Text::getList( 100000, $results['datime'] ? $results['datime']->id : null);
$results['texts'] = $data['results'];
$results['totalRows'] = $data['totalRows'];
require( TEMPLATE_PATH . "/sms.php" );
}

Answer 1

so just try:
public static function getList( $numRows=1000000, $datimeId=null, $andClause=null ) {
and here :
$data = Text::getList( 100000, $results['datime'] ? $results['datime']->id : null, 'testMethod');
and off course here:
$sql = "SELECT SQL_CALC_FOUND_ROWS * FROM notify $datimeClause";
if ($andClause!=null ) $sql .= " AND method= :method ";
$st = $conn->prepare( $sql );
$st->bindValue( ":numRows", $numRows, PDO::PARAM_INT );
$st->bindValue( ":datimeId", $datimeId, PDO::PARAM_INT );
if ($andClause!=null )
$st->bindValue( ":method", $andClause, PDO::PARAM_STR );

Answer 2

Okay, the first getById query I ran in my call function was arbitrary.
This works:
public static function getList( $numRows=1000000, $datimeId, $method=1 ) {
$conn = new PDO( DB_DSN, DB_USERNAME, DB_PASSWORD );
$datimeClause = $datimeId ? "WHERE DatimeId = :datimeId" : "";
$sql = "SELECT SQL_CALC_FOUND_ROWS * FROM notify $datimeClause AND Method= :method LIMIT :numRows";
$st = $conn->prepare( $sql );
$st->bindValue( ":numRows", $numRows, PDO::PARAM_INT );
$st->bindValue( ":datimeId", $datimeId, PDO::PARAM_INT );
$st->bindValue( ":method", $method, PDO::PARAM_INT );
$st->execute();
$list = array();
while ( $row = $st->fetch() ) {
$text = new Text( $row );
$list[] = $text;
}
// Now get the total number of articles that matched the criteria
$sql = "SELECT FOUND_ROWS() AS totalRows";
$totalRows = $conn->query( $sql )->fetch();
$conn = null;
return ( array ( "results" => $list, "totalRows" => $totalRows[0] ) );
}
function newAutoText() {
$results = array();
$datimeId = ( isset( $_GET['datimeId'] ) && $_GET['datimeId'] ) ? (int)$_GET['datimeId'] : null;
$data = Text::getList( 100000, $datimeId, '1');
$results['texts'] = $data['results'];
$results['totalRows'] = $data['totalRows'];
require( TEMPLATE_PATH . "/sms.php" );
}
