在sql查询中自定义顺序

Question

I am working a report which require custom order by statement. I have 5 categories which I am using for the order by clause. These are my column names student expenses, petty cash expenses, home expenses, daily expenses, Fair expenses. I want to order them in report in this manner:

Pettycash
DailyExpense
Home Expense
Fair Expense
Cash Expense

Also if new categories are added that wont effect this order and added in the last. I have tried order by asc and desc also searched some forums but it didnt cleared my concept. Thank you.

Answer 1

Try following:

ORDER BY
CASE Category
   WHEN 'Pettycash' THEN '1'
   WHEN 'DailyExpense' THEN '2'
   WHEN 'Home Expense' THEN '3'
   WHEN 'Fair Expense' THEN '4'
   WHEN 'Cash Expense' THEN '5'
   ELSE '6' 
END
