Ms access使用join访问Query错误

Question

我有ms访问查询的问题。 我在查询中选择了2个表：table1有2个项目，table2有3个项目，两者都与billno连接但是当我在查询中构建查询时，这变为like this：

SELECT
  productionpurchase.PurchNo,
  productionpurchase.Medicine AS PpurchMedi,
  productionpurchase.Qty AS PPurchqty,
  productionpurchase.Price AS PpurchTP,
  productionpurchase.Srate AS PpurchRP,
  productionpurchase.Desc AS PpurchDesc,
  production.desc,
  production2.ExtraQty,
  production.*
FROM (productionpurchase
  INNER JOIN production ON productionpurchase.PurchNo = production.BillNo)
  INNER JOIN production2 ON productionpurchase.PurchNo = production2.BillNo;
