我有兴趣知道是否有任何MySQL / Oracle函数给增量号。在另一列相似的值的基础上的一列？

就像在我的下面的代码中，我有order_primary列，其中包含订单号。所以基于此我们可以确定有多少产品属于特定订单。 count也用于存储1,2,3等的值

但我面临的问题是数值正在增加......

我的代码 -

$query_product = "SELECT name, id,qty_ordered,price,row_total,base_subtotal,

base_shipping_amount,base_grand_total,order_primary,message

FROM sales_order WHERE `prod_Flag`=0 ";

$result_query_product = mysql_query($query_product);

$count = 0;

while($row = mysql_fetch_array($result_query_product))

{

$count++;

$name = ($row["name"]);

$message1 = ($row["message"]);

$result_str_product .= "('". mysql_real_escape_string($name) . "',". "'" . $row["sku"] . "'," . "'" . $row["qty_ordered"] . "',". "'" . $row["price"] . "'," . "'" . $row["row_total"] . "'," . "'" . $row["base_subtotal"]. "'," . "'" . $row["base_shipping_amount"] . "'," . "'" . $row["base_grand_total"] ."',". $row["order_primary"].",". $count.",". "'".mysql_real_escape_string($message1)."'".", NOW()),";

}

$query_prod_insert = "INSERT into sales_product(name, sku, qty_ordered, price, row_total, base_subtotal, base_shipping_amount,base_grand_total,prod_foreign,count,message,product_creation_date) VALUES ".$result_str_product;

$final_query = substr_replace($query_prod_insert,";",-1);

$result_query_product_outbound = mysql_query($final_query);所以我的o / p是 - ：

('shirt','st','2.0000','75','150','150','20','170',29,1,NOW()),

('tie' ,'te','2.0000','50','100','100','10','110',29,2,NOW()),

('tie' ,'te','2.0000','50','100','100','10','110',29,3,NOW()),

('socks','sk','5.0000','20','100','100','05','105',30,4,NOW());

('jackt','jt','3.0000','40','120','120','15','135',30,5,NOW());但是我想要像这样的o / p：

('shirt','st','2.0000','75','150','150','20','170',29,**1**,NOW()),

('tie' ,'te','2.0000','50','100','100','10','110',29,**2**,NOW()),

('tie' ,'te','2.0000','50','100','100','10','110',29,**3**,NOW()),

('socks','sk','5.0000','20','100','100','05','105',30,**1**,NOW());

('jackt','jt','3.0000','40','120','120','15','135',30,**2**,NOW());那么是否有任何MySQL / Oracle功能给增量号。在另一列相似值的基础上，即在我的情况下，对于相同的订单号。值为29，计数值应该是1,2,3&对于相同的订单号。 30，计数值应该是1,2 ......

那么是否有任何功能或如何做到这一点。
