Question

Does anyone happen to know why this query when executed in phpMyAdmin gives me all the data I need.

But when executed programmatically in PHP, it returns 0 rows.

Thanks!

 SELECT `table_schema`, `table_name` 
     FROM `information_schema`.`TABLES` 
     WHERE `Engine`='MyISAM' 
     AND `TABLE_SCHEMA` !='information_schema' 
     AND `TABLE_SCHEMA` !='mysql';

Update:

Here is the asked for PHP code.

$query = "SELECT `table_schema`, `table_name` 
    FROM `information_schema`.`TABLES` 
    WHERE `Engine`='MyISAM' AND `TABLE_SCHEMA` !='information_schema' AND `TABLE_SCHEMA` !='mysql'";
$result = mysql_query($query);

echo '--:'.mysql_num_rows($result).':--';
while ($row = mysql_fetch_array($result)) {
    print_r($row);
}

And yes I’m using double quotes…

Serhiy,

I have also tried this sort of thing, and what I noticed is that phpmyadmin query strings are not exactly compatible with PHP query strings. phpmyadmin, tends to add a few extra characters to its query strings.

In your PHP query try something like:

SELECT table_schema, table_name FROM information_schema.TABLES WHERE TABLE_SCHEMA <> 'information_schema' AND TABLE_SCHEMA <> 'mysql'

Good luck!
