插入时忽略其中包含空值的记录

Question

我有下表：

发明人（发明人ID，专利号，发明人第一，发明人最后，城市，州）

其中 inventoryid 为 pk，patentno 为 fk。

这是当前的插入代码：

insert into Inventor (PatentNo, InventorFirst, InventorLast, City, statename, country, NationalityCountry, ResidenceCountry)
select PatentNo, InventorFirstname, InventorLastname, City, statename, country, NationalityCountry, ResidenceCountry
from InventorUpdate;

我想修改它，以便如果 InventorFirstname 和 InventorLastname 字段为空，则它不会插入到inventor表中

Answer 1

您如何保留那些字段为空的记录而不被选择？

insert into Inventor (PatentNo, InventorFirst, InventorLast, City, statename, country, NationalityCountry, ResidenceCountry)
select PatentNo, InventorFirstname, InventorLastname, City, statename, country, NationalityCountry, ResidenceCountry
from InventorUpdate
Where InventorFirstname is not null 
And   InventorLastname is not null;
