Thanks GJ for the MySQL defaults.
In v5.11 - adodb.inc.php:
function RowLock($table,$where,$col='1 as adodbignore')
was in v5.10
function RowLock($table,$where,$col='1 as ignore')
Now analysing the differences between v5.11 and v5.10, we find that a new
class variable called
var $bulkBind = false; // enable 2D Execute array
has been newly introduced in v5.11 of adodb.inc.php in the class
ADOConnection
This variable is used as an additional check in v5.11 at line 956:
$array_2d = $this->bulkBind && is_array($element0) &&
!is_object(reset($element0));
The Last Insert ID is essentially an SQL statement in ADODB and hence the
above may something to do with it.
