Question

Say i have a table Guest and it has column g_id : values 1 to 10.

Now i want the query to return me the g_id’s neither in ascending order nor in descending..
but i want the 4th then 3rd and then 5th entry, in this particular order.
Also i want just the 4th 3rd and 5th entry.

say my entries have an id and a name . ;i.e. my table Guest has these two tables.
Now my table is as following.

1 A
2 B
3 C
4 D
5 E
6 F
7 G
8 H
9 I
10 J

Now i want just the entry with 4th 3rd and 5th g_id, and in this particular order.

How do i write the SQL query?
Thanks.

Select * from Guest ___________???

Kindly fill in the gaps.

Answer 1

You can use a CASE statement in your ORDER BY to use a fake column to sort on and a WHERE IN clause to only return the values you need.

SELECT * 
FROM   Guest
WHERE  g_id IN (3, 4, 5)
ORDER BY
       CASE WHEN g_id = 4 THEN 1
            WHEN g_id = 3 THEN 2
            WHEN g_id = 5 THEN 3
       END
