Question

Faily new to php and mysql, this will probably seem very messy.

This is what I came up with:

$query = "show tables like 'whatever%'";
$result = mysql_query($query);
$num_results = mysql_num_rows($result);

for ($i = 0; $i < $num_results; $i++)
{
$row = mysql_fetch_array($result);
$sql=mysql_query("SELECT * FROM ". $row[0] ." WHERE a=(SELECT MAX(a)) AND b=(SELECT MAX(b)) AND c LIKE 'd%' ORDER BY date DESC LIMIT 1"); 


while($info=mysql_fetch_array($sql)){ 
  echo "...";
}
}

I get the desired value from each table, so x results depending on the amount of tables. What I would like is to have the results of the queried tables but only show the top 10-5 ordered by date/time.

Is this possible with the current script? Is there an easier way (while, number of tables changing constantly)? Is this query method database intensif?

Cheers!

Answer 1

I call constantly changing number of tables having similar structure a design error. also query switch to

$sql=mysql_query("SELECT * FROM $tbl WHERE c LIKE 'd%' ORDER BY a DESC, b DESC, date DESC LIMIT 1"); 

is a little relief to database.
