NULLs into empty strings as well as the other way around. It still doesn't
help a great deal in the long run, but at least the option is there.
Make sure hash tables are nulled out to avoid double freeing them.
Additional ugliness required because mysql does stupid stuff like this:
mysql> CREATE TABLE foo (id int) TYPE=innodb;
Query OK, 0 rows affected, 2 warnings (0.00 sec)
mysql> SHOW CREATE TABLE foo;
CREATE TABLE `foo` (
`id` int(11) default NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1
In addition, BEGIN, COMMIT and ROLLBACK all succeed, even when no tables
support transactions.
proto bool PDOStatement::closeCursor()
Closes the cursor, leaving the statement ready for re-execution.
The purpose of the function is to free up the connection to the server so that
other queries may be issued, but leaving the statement in a state that it can
be re-executed.
This is implemented either as an optional driver specific method (allowing for
maximum efficiency), or as the generic PDO fallback if no driver specific
function is installed.
The PDO generic fallback is semantically the same as writing the following code
in your PHP script:
do {
while ($stmt->fetch())
;
if (!$stmt->nextRowset())
break;
} while (true);
These are effectively named statements with strong constraints on the naming
format. We cater for this in a fairly generic way: allow a driver to replace
the format string we use to generate names from positional parameters. In
addition, if that format is set, we always force a rewrite from regular names
to the strongly enforced names.
floating point values into strings during fetch. This is a compatibility hack
for drivers that return native types rather than string representations.
We use this flag in the test suite to persuade postgres tests to pass.
by name, even when multiple columns have the same name:
$sql = "SELECT 1 a, 2 a, 3 b, 4 c, 5 d, 6 c, 7 a";
echo "$sql\n";
print_r($db->query($sql)->fetchAll(PDO_FETCH_NAMED));

Also added two new attributes for use at prepare time;
PDO_ATTR_FETCH_TABLE_NAMES and PDO_ATTR_FETCH_CATALOG_NAMES instruct the driver
that the names of the columns that they return to PDO should include the table
and catalog names respectively. Both attributes may be used together or
independently. The catalog, table and column name components should be
separated by a . character.
