How to pull columns with '1' in MySQL - php

Question

I was wondering if there was an easy way to do this:
I have a user_id column and then 33 other columns with either a '0' or a '1' as the type. How can I easily select all of the columns where the user_id = 320 and the column's data equals 1?
The column titles are labeled 1-33. In the end I want to join it to another table where 1-33 is the id to a label column.
Does this make sense?
Thanks for any help!

Answer 1

Try this I get all the fields and test if it BIT and then inject it to the query
And please tell me the result
<?php
$result = mysql_query("SHOW COLUMNS FROM sometable");
if (!$result){
echo 'Could not run query: ' . mysql_error();
exit;
}
if (mysql_num_rows($result) > 0){
$str ="";
$nums = mysql_num_rows($result);
$i = 0 ;
while ($row = mysql_fetch_assoc($result)){
$i++;
if($row['Type'] = 'BIT' && $i != $nums){
$str .= " WHERE `".$row['Field']."` = 1 AND";
}
elseif($row['Type'] = 'BIT' && $i == $nums){
$str .= " WHERE `".$row['Field']."` = 1 ";
}
}
}
$query = "SELECT * FROM mytable user_id = 320 AND ".$str;
$q = mysql_query($query);
This is for the first part of you question
the second part the same operation
and this working without knowing the fields name
