Question

I have two tables; table1, table2, however table1 only has 1 record and table2 has 3 records im trying to join the tables so that it only shows one record from table 1 but all three from table2 without duplicating the values from table1

SELECT * from table1 a
inner  join table2 b on
a.table1_id=b.table2_id

I have tried this but it still return a duplicate of the row in table1 and as I stated I tryin to get the 1 row from table1 joining with the three rows from tabl2 without showing the duplicates from table1

Answer 1

It doesn’t make sense to pull out one row from one table and three rows from another table on a JOIN. What would such a result set even look like? The closest you can get is to GROUP by table1.id and GROUP_CONCAT() the table2 values.

E.g:

SELECT
    t1.id,
    GROUP_CONCAT(t2.id SEPARATOR ', '),
    GROUP_CONCAT(t2.name SEPARATOR ', ')
FROM
    t1
INNER JOIN t2 ON t1.id = t2.t1_id
GROUP BY
    t1.id
