<entry>
|
|
PDO_CUBRID supports scrollable cursors. The default cursor type is
|
|
forward only, and you can use parameter driver_options in
|
|
<function>PDO::prepare</function> to change cursor type.

<entry>Autocommit_mode and Transaction</entry>
|

<entry>
|
|
PDO_CUBRID supports both autocommit_mode and transaction, and
|
|
autocommit_mode is enabled by default. You can use
|
|
<function>PDO::setAttribute</function> to change its state.
|
|
|
|
<para>
|
|
If you use <function>PDO::beginTransaction</function> to begin a
|
|
transaction, it will disable autocommit_mode automatically and
|
|
restore it after <function>PDO::commit</function> or
|
|
<function>PDO::rollBack</function>. Note that before disabling the
|
|
autocommit_mode, any pending work is automatically committed.

<entry>LOBs</entry>
|
|
<entry>PDO_CUBRID supports BLOB/CLOB data type. The LOB in PDO is
|
|
represented as a stream, so you can insert LOBs by binding a stream,
|
|
and get LOBs by reading a stream returned by CUBRID PDO. For example:
