在插入时忽略其中包含空值的记录

Question

我有下表：

inventor(inventorID, PatentNo, InventorFirst, InventorLast, City, State)

inventorid 是 pk，patentno 是 fk。

这是当前插入代码：

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，如果 InventorFirstname 和 InventorLastname 字段为空，则它不会插入到发明人表中

Answer 1

如何保留那些字段为空的记录不被选中？

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;
