尝试运行SQL查询以显示针对EAN的标识符值。

如果EAN不存在，我如何为Identifier返回NULL值？所以我查询列表，我必须先看看EAN是否存在并返回标识符。如果不存在以获取NULL记录

查询位于

之下

1 个答案:

答案 0 :(得分：2)

要返回NULL值，您可以使用left join。一种典型的方法是：

select sp.Identifier, n.EAN
from (select '98132361069' as EAN union all
      . . .
     ) n left join
     StarProduct sp
     on sp.EAN = n.EAN;

如果EAN的列表已经来自查询，则更容易将该查询包含在n而不是列表中。
