Hi all,
I read in DuBois's MySQL, Perl DBI API Reference part, it is written:
$rv = $sth->rows();
Return the number of rows affected by the statement associated with $sth
or -1 if an error occured. This method is used primarily for statements
that do not return rows. For SELECT statements, you should not rely on the
rows() method; count the rows as you fetch them instead.
My question is, why we should not rely on $sth->rows()? Does it mean that
it doesn't match sometime? Anybody ever experienced?
Also, in the case of "ERROR 1114: The table 'SQL22e0b00_0' is full". I
found that this function returned -2 instead of -1.
