MySql - 为其他表的每个ID插入行

Question

I'm sure this is simple I just cant get the correct search terms to find the answer. But I have one table for locations with IDs

ID| Name

1 | Foo

2 | Bar

3 | Blah

and another table (table2) that has a field referencing those location IDs:

ID| LocationID | Foo | Bar

1 | 1          | ... | ...

2 | 2          | ..

3 | 5          | ...

Where LocationId = a value from location. What I want to do is for every ID in location (1,2,3...) add a record to the other table. So for example:

"insert into table2 (locationID, foo, bar) values (1, "hello", "world");"

"insert into table2 (locationID, foo, bar) values (2, "hello", "world");"

and so on..

Answer 1

你可以使用INSERT INTO ... SELECT ，所以为你的例子

INSERT INTO table2 (locationID, foo, bar) SELECT ID, 'hello', 'world' FROM table1

Answer 2

You can do an Insert... Select

Insert Table2 (LocationID, Foo, Bar)
Select ID, "Hello", "World"
From Location
