I want to do a query that fetchs the rows ordered by the value of a column and in the same time i want it fetches first the rows that has a concret value in that column.
例如:
it
es
fr
it
es
fr
如果首先要用“是”,结果将是:
es
es
it
it
fr
fr

我在这里想首先把记录放在一栏和之后,其余部分按赞同顺序排列(如你正在使用藐视法庭命令)。
如果是这样的话,你可以这样做(以Oracle语)。
Select *
From
(
Select T.*, 0 orden
From Table T
Where column_name= es
Union
Select T.*, 1 orden
From Table T
Where column_name <> es
)
Order By orden, column_name
修改该栏的次序,只是按条款顺序排列。
EDIT:MySQL试图相反
Select *
From
(
Select T.*, 0 orden
From Table AS T
Where column_name= es
Union
Select T.*, 1 orden
From Table AS T
Where column_name <> es
)
Order By orden, column_name
