Question

I have couple auto increment s.no and respective names in my mysql database.

Currently the queries written are like below.

    $result = mysql_query ("SELECT name FROM table WHERE s.no= '1'") or die (mysql_error ());
    while($row = mysql_fetch_array($result)){

    $name1= $row['name'];
    }

    $result = mysql_query ("SELECT name FROM table WHERE s.no= '2'") or die (mysql_error ());
    while($row = mysql_fetch_array($result)){

    $name2= $row['name'];
    }

How could this be optimized, to have a single query and assign name1 from s.no=1, nameN from s.no=N??

Answer 1

You could do this with an IN clause.

 SELECT name, s.no as no FROM table WHERE s.no IN ('1', '2')

Then, dynamically look up the variable with the string.

$varName = 'name'.$row['no'];
$$varName = $row['name];
