Question

I have run into a 1-N situation. i.e 1 record in 1st table will have multiple records in second table, I just wanna fetch all data corresponding to the ID in 1st table using joins, is this possible.

table 1 :  ID  name
            1   pradeep

table 2:   ID table1_id   orders
           1   1           23
           2   1           25
           3   1           26

In a single query i should get all records. I don’t wanna loop as i am doing it and its taking lot of time.

I want to display user html output in manner like this. So there lies the problem.

ID Name orders1 orders2 orders order4

Answer 1

SELECT 
    t2.* /* fetch data from second table */
FROM 
    table1 t1 
LEFT JOIN table2 t2 on t2.table1_id = t1.id
WHERE t1.id = <id>;

I wouldn’t recomment it though. Why don’t you just run it as 2 separate queries?
