MySql - Insert row for each ID of other table
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..

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

You can do an Insert... Select
Insert Table2 (LocationID, Foo, Bar)
Select ID, "Hello", "World"
From Location
