I want to ORDER my sql query based on the IN clause

select * from acct where acct_num in (200,100,150) order by (200,100,150)

My result is ordered by
100,150,200
I assume because acct_num is an index.

I want my resulting order to be
200,100,150

you then need to write the order by like that:
select * from acct where acct_num in (200,100,150)
 order by case when acct_num = 200 then 0 when acct_num =  100 then 2 else 3 end

Is there an easier way to do this query?
The IN list will be dynamic.

Try this:
SELECT * FROM acct WHERE acct_num IN (200,100,150) ORDER BY FIELD(acct_num,200,100,150);
