If the last SQL statement executed by the associated
|
|
<literal>PDOStatement</literal> was a SELECT statement, some databases
|
|
may return the number of rows returned by that statement. However, this
|
|
behaviour is not guaranteed for all databases and should not be relied
|
|
on for portable applications.
