Adding columns to mysql by fetching data from other table

I am fetching data from a column of another table and inserting so it adds the number columns in this table according to the number of data present in the first column, but its not working.

$que='select n_quid from nsnsbl0122_qp order by n_quid asc';
$que1=mysql_query($que);
$que2=mysql_num_rows($que1);
$table  = 'ns22_sp';
 
for($i=0;$i<$que2;$i++){

   $ que3=mysql_fetch_array($que1);


    $add = mysql_query("ALTER TABLE $table
    ADD COLUMN ".$que3['n_quid']." SMALLINT(6) NOT NULL,
    AFTER f_ex_status");



};  


};
