What’s new? (since the book)
$sth = $dbh->primary_key_info($cat, $schema, $table);
- Return information about the primary keys of a table
@keys = $dbh->primary_key($cat, $schema, $table);
- Simpler way to return information about the primary keys of a table
$h->trace(…)
- Trace level 1 only shows return from first and last fetch() calls
- Trace level 2 only shows returns from fetch() calls
- Trace level 3 shows entry and return from fetch() calls
- Those changes will make it easier to use lower trace levels without drowning in data
