如何查看以下查询返回的行数?
mysql_select_db($database_aoldatabase, $aoldatabase);
$query1 = "select * from sale where secid = $invoiceno ";
$query2 = "select * from sale where secid = $invoiceno ";
$maxa = mysql_query ($query1)
or die ("Query '$query' failed with error message: \"" . mysql_error () . '"');
$maxa2 = mysql_query ($query2)
or die ("Query '$query' failed with error message: \"" . mysql_error () . '"');
$row = mysql_fetch_array($maxa);
$row2 = mysql_fetch_array($maxa2);
最佳答案
就像米切尔说的,做这项工作。但是,如果要使用数组处理多行,也可以使用mysql_num_rows()
。
$data = array();
while($row = mysql_fetch_array($maxa, MYSQL_ASSOC)) {
$data[] = $row;
}
$count1 = mysql_num_rows($maxa);
$count2 = count($data);
