SQL查询报表内连接

Question

我想按日期获取报告，我想将购买的商品和商品库存进行 INNERJOIN，但我似乎弄错了这里是我的代码：

$query=mysqli_query($con,"select month(tblpurchase.PostingDate_p) as mnth,year(tblpurchase.PostingDate_p)
 as yearr,day(tblpurchase.PostingDate_p) as date,tblpurchase.Itemname as itmname, tblpurchase.Quantity as
 pquantity, tblpurchase.Damaged as dmgq, from tblpurchase  INNER JOIN tblitem ON tblpurchase.ItemId = 
tblitem.id where date(tblpurchase.PostingDate_p) between '$fdate' and '$tdate'");

这是我的桌子

表项

id|ItemName|beginv|stock|PostingDate

购买

id|Itemname|ItemId|Quantity|Damaged|LatestInv|PostingDate_p|UpdatingTime

Answer 1

运行这个，在最后一个返回的 clum 之后你不需要逗号

$query=mysqli_query($con,"select month(tblpurchase.PostingDate_p) as mnth,year(tblpurchase.PostingDate_p)
 as yearr,day(tblpurchase.PostingDate_p) as date,tblpurchase.Itemname as itmname, tblpurchase.Quantity as
 pquantity, tblpurchase.Damaged as dmgq from tblpurchase  INNER JOIN tblitem ON tblpurchase.ItemId = 
tblitem.id where date(tblpurchase.PostingDate_p) between '$fdate' and '$tdate'");
