LOB Locator Methods The following driver-specific methods let you manipulate "LOB Locators". LOB locators can be selected from tables directly, if the ora_auto_lob attribute is false, or returned via PL/SQL procedure calls. (If using a DBI version earlier than 1.36 they must be called via the func() method. Note that methods called via func() don't honour RaiseError etc, and so it's important to check $dbh->err after each call. It's recommended that you upgrade to DBI 1.38 or later.)
