W:行,到星期五那天我一定把会议室准备好。
查询9没有为该员工生成一行,因为for循环遍历的是不同的office值,这些值不包括丢失的办公室信息。
Query 9 doesn't produce a row for that employee because the for loop iterates over the distinct office values which do not include missing office information.
请注意,在查询10中多获得了一行,这是因为SQL的group by函数还为null值生成一个组,我们的示例表中有一名员工没有办公室信息。
Note that we get an extra row from Query 10, because SQL's group by also produces a group for NULL values, and there is one employee in our sample table with no office information.
