The empty resultset is not the error. Calling fetch() on an empty
resultset sets the error code to a warning and/or generates an
exception in every database engine I've seen.
In Oracle, it's error ORA-1403: no data found.
It's SQL_NODATA in ODBC drivers.
I believe it's Error 2053 in MySQL. mysql_stmt_fetch() returns
MYSQL_NO_DATA, and not 0 for success.
In it's current state, fetch() returning null without raising the
exception means we'll have to add the test and throw the exception
manually on every single query.

Empty resultset is not an error, it's a common situation.
No bug here.

Sorry, error code should be 02, not 20

Description:
------------
A fetch against a statment that returns an empty resultset doesn't set
any PDO error information, nor does it raise an exception.
Testing against MySQL 5.0.18
Reproduce code:
---------------
Database connection is successful, and mode is set to throw
exceptions:
try
{
$sth = $dbh->prepare("SELECT * from any_table where 1=2");
$sth->execute();
$row = $sth->fetch();
echo "ERROR=" . $sth->errorCode();
}
catch (PDOException $e)
{
dbg("DB Error!: " . $e->getMessage());
die();
}
Expected result:
----------------
Either
ERROR=20
when not using exceptions, or an exception.
Actual result:
--------------
ERROR=00
