从按列值排序的表中获取记录

Question

I have a table with a column to maintain the state of the record. ie

-----------------------------
| id  | desc      | state    |
-----------------------------
| 1   | desc 1    | Complete |
| 2   | desc 2    | Open     |
| ... | ...       | ...      |
-----------------------------

I want fetch the records in the order of 'Open' followed by 'Complete'. Can I get this done using one SQL query? If so, how should I write it?

Answer 1

是的，您可以使用ORDER BY语句和FIELD函数来执行此操作：

SELECT * FROM table1 ORDER BY FIELD(state, 'Open', 'Complete')

Answer 2

Try something like this:

select * 
from table_name 
order by decode (state, 'Open', 1, 'Complete', 2, 3)
