I need to create a select query which fetches records according to multiple variables like:

<?PHP

@$task=$_REQUEST['task'];
@$Country=$_REQUEST['Country'];
@$City =$_REQUEST['City'];
@$MosqName =$_REQUEST['txtMsqName'];
@$PostCode =$_REQUEST['txtPostalCode'];

$sql_serch="SELECT  Country="."'".$Country."'", " City="."'".$City."'"." FROM job_mosqu";
?>

Bu çalışmıyor.
