如何在一条 SQL 语句中使用两个变量？

Question

我遇到了关于 SQL 和 Python 的问题。

在我的代码中，我尝试使用输入字段搜索两个元素。它是CommercialCode 或ItemNumber。 ItemNumber 的这段代码工作得很好（只是最后一部分很重要）：

SQL_Query = pd.read_sql_query("Select top 1 UnitWeight, GlobalItemDescription.ItemNumber, GlobalItemDescription.Description,  GlobalItemMaster_new.CommodityCode, CommercialCode, GlobalItemMaster_new.DRICode  from dbo.GlobalItemDescription inner join dbo.GlobalItemMaster_new on GlobalItemDescription.ItemNumber = GlobalItemMaster_new.ItemNumber where dbo.GlobalItemDescription.ItemNumber like '%s'" % eingabe, conn)

但实际上我想要这样：

SQL_Query = pd.read_sql_query("Select top 1 UnitWeight, GlobalItemDescription.ItemNumber, GlobalItemDescription.Description,  GlobalItemMaster_new.CommodityCode, CommercialCode, GlobalItemMaster_new.DRICode  from dbo.GlobalItemDescription inner join dbo.GlobalItemMaster_new on GlobalItemDescription.ItemNumber = GlobalItemMaster_new.ItemNumber where dbo.GlobalItemDescription.ItemNumber like '%s' OR dbo.GlobalItemMaster_new.CommercialCode like '%s'" % eingabe, eingabe2,conn)

当我执行上面的代码时，我得到了这个错误：

TypeError: 格式字符串的参数不足

你必须使用paranthesis，所以它应该是% (eingabe, eingabe2)而不是% eingabe, eingabe2

 SQL_Query = pd.read_sql_query("Select top 1 UnitWeight, GlobalItemDescription.ItemNumber, GlobalItemDescription.Description,  GlobalItemMaster_new.CommodityCode, CommercialCode, GlobalItemMaster_new.DRICode  from dbo.GlobalItemDescription inner join dbo.GlobalItemMaster_new on GlobalItemDescription.ItemNumber = GlobalItemMaster_new.ItemNumber where dbo.GlobalItemDescription.ItemNumber like '%s' OR dbo.GlobalItemMaster_new.CommercialCode like '%s'" % (eingabe, eingabe2),conn)
