my @row = $Statement->fetchrow_array; if ($row[0] > 0) ... LogError("NICK_TAKEN"); return("-1"); }
$rv = $sth->rows; Returns the number of rows affected by the last row affecting comm +and, or -1 if the number of rows is not known or not available. ... For SELECT statements, it is generally not possible to know how ma +ny rows will be returned except by fetching them all. Some drivers wi +ll return the number of rows the application has fetched so far, but +others may return -1 until all rows have been fetched. So use of the +rows method or $DBI::rows with SELECT statements is not recommended. One alternative method to get a row count for a SELECT is to execu +te a "SELECT COUNT(*) FROM ..." SQL statement with the same "..." as +your query and then fetch the row count from that.
