[英]How to write SQL Query for this case?
Suppose I have a tableA - 假设我有一张桌子A-
id value id值
1 a 1个
2 d 2天
tableB 表B
idTableA someValue someOtherValue idTableA someValue someOtherValue
1 de 1天
1 xy 1 xy
Now in tableB I want to insert rows where idTableA would come from tableA and custom values in somevalue and someOtherValue. 现在在tableB中,我想插入idTableA来自tableA的行,并在somevalue和someOtherValue中添加自定义值。
I want to write a query like this: 我想写这样的查询:
insert into B (idTableA,someValue,someOtherValue)
values(idTableAValue, 'value1', 'value2')
(select idTableA from TableA )
What is the best way to do this? 做这个的最好方式是什么?
Try this: 尝试这个:
insert into B (idTableA, someValue, someOtherValue)
select idTableA, 'value1', 'value2'
from TableA
