Is there a limitation to the length of the query in mysql?
- by Bakhtiyor
I am asking this question because I need to know this limitation as I am generating SELECT query in my PHP script and the part of WHERE in this query is generated inside the loop. Precisely it looks like this
$query="SELECT field_names FROM table_name WHERE ";
$condition="metadata like \"%$uol_metadata_arr[0]%\" ";
for($i=1; $i<count($uol_metadata_arr); $i++){
$condition.=" OR metadata like \"%$uol_metadata_arr[$i]%\" ";
}
$query.=$condition;
$result=mysql_query($query);
So, that's why I need to know how long my $query string can be, because the array *$uol_metadata_arr* could contain many items.
