sql合并相同主键的行

Question

In here you can see the nested or statement which allows me to combine the answers.text and answers.integer to the same table in some order

But what I would like to do is have the integers and text on the same row if they have the same submission id. How would I do that?

EDIT: The concat was supposed to combine the two on the same line, or so I thought. But it had just took out the nulls from the columns so that there were only two -> submissions and building_idquant. When before there was submission_id, building_id, and integer.

Answer 1

its tough to get your expectation from image but i thought after seeing your image you need below somethin

select submission_id,building_idquant ,
    concat(CONVERT(varchar(50), submission_id),building_idquant ) as id_quant from
    (
    select distinct submission_id,building_idquant from tablename 
    ) t
