Concatenate multiple rows in single rows in MySQL

Question

How can I concatenate all the rows in single rows when I fire SELECT query?

Answer 1

You'll need GROUP_CONCAT and CONCAT mysql functions and the query should look like this:

SELECT GROUP_CONCAT( CONCAT( id, ' ', name, ' ', city, ' ', state) SEPARATOR ' ')
FROM students
GROUP BY (1)

Or you can use CONCAT_WS instead:

CONCAT_WS(' ', id, name, city, state)
