MySQL的插入到...选择

Question

I want to select one row in a table and insert it into another table like this:

INSERT INTO  positionenneu
select *
from positionenneu_0603 where belegnummer like '4106192%'

I got an error because of duplicating id values. In both tables is id primary key AUTO_INCREMENT. How can I do this without id column? Thank you for the answer. Have a nice day!

Answer 1

Don't use the * and specify the column list instead, naturally omitting the id column:

INSERT INTO  positionenneu (foo, bar, baz)
select foo, bar, baz
from positionenneu_0603 where belegnummer like '4106192%'

Or you can of course use the id column somewhere if you need:

INSERT INTO  positionenneu (foo, bar, baz, positionenneu_0603_id)
select foo, bar, baz, id
from positionenneu_0603 where belegnummer like '4106192%'

Answer 2

It's good practice to specify the columns that you are inserting. This also allows you to skip the id field:

INSERT INTO  positionenneu (field1,field2,field3)
    select field1_0603, field2_0603, field3_0603
    from positionenneu_0603 where belegnummer like '4106192%'
