Question

我有一个餐桌工厂当我选择记录时，返回以下结果： -

SELECT PLANT_NAME FROM PLANT

Plant_Name
-----------
Chicago 65th
-----------
Clearfield
-----------
Lithonia
-----------
Los Angeles
-----------
North Bergen
-----------
Zellwood
-----------
Olathe
-----------
Archerfield
-----------
Epping
-----------

我编写以下查询以显示工厂名称＆＃34; Zellwood＆＃34;在倒数第二和＆＃34; Archerfield＆＃34;在最后一排。查询是

select Plant_Name from plant order by  case  Plant_Name

 when 'Zellwood' then 1
 when  'Archerfield' then 2
 end

但它没有订购其余的记录。请给我建议我如何按升序订购其余的记录。

Answer 1

使用ORDER BY中的第二个键：

select Plant_Name
from plant
order by (case Plant_Name
             when 'Zellwood' then 1
             when 'Archerfield' then 2
          end),
         Plant_Name;

Answer 2

查询

select ColumnName
    from Tablename
    order by (case Column Name when 'value' then 1 when 'value' then 2 end), Column Name);

SQL Query使用CASE语句对记录进行排序
