[Vtigercrm-developers] adodb version

[Adam Heinz]

So I spent spent some time trying to get PDO running beneath ADOdb.
It was easy enough to ask ADOdb to use its built-in PDO wrapper (see
attached patch), but I immediately started seeing weirdness.  When I
attempted to log in, Users->retrieve_entity_info failed.  Digging in,
the select from vtiger_field was reporting 40 rows via $adb->num_rows,
but ten rows in it started returning null data.  Not sure where to
proceed from here, so aborting for now.

In my follow up reading, I came across a slideshow [1] by Oracle that
goes so far as to declare parts of PDO "broken by design" (without
much in the way of supporting details).  I think the next pass I take
at improving database performance, I will look at what is necessary to
use mysqlnd instead of libmysql.
