SQL Server 2012 - 数据更新操作

SELECT  *
FROM    dbo.Student;

--1， 插入数据  Insert ,逗号分隔可以同时插入多条
INSERT  dbo.Student
        ( StuID, Class, StuName, StuEnName, StuAge, StuBirthday, StuSex,
          Height, Remark )
VALUES  ( \'007\', -- StuID - varchar(10)
          3, -- Class - int
          N\'呵呵\', -- StuName - nvarchar(50)
          \'Hehe\', -- StuEnName - varchar(50)
          22, -- StuAge - int
          GETDATE(), -- StuBirthday - datetime
          N\'男\', -- StuSex - nvarchar(10)
          190, -- Height - int
          \'test\'  -- Remark - text
          ),
        ( \'008\', -- StuID - varchar(10)
          3, -- Class - int
          N\'你好\', -- StuName - nvarchar(50)
          \'Nihao\', -- StuEnName - varchar(50)
          25, -- StuAge - int
          GETDATE(), -- StuBirthday - datetime
          N\'女\', -- StuSex - nvarchar(10)
          190, -- Height - int
          \'test\'  -- Remark - text
          );

--2， 从一个表网另外一个表中写入数据
INSERT  INTO dbo.Student
        SELECT  \'009\' ,
                Class ,
                \'猫咪\' ,
                \'Kitty\' ,
                StuAge ,
                StuBirthday ,
                StuSex ,
                Height ,
                Remark
        FROM    dbo.Student
        WHERE   StuID = \'008\';

-- 3, OUTPUT 抛出写入的StuID
DECLARE @stuId VARCHAR(10)
INSERT  dbo.Student
        ( StuID, Class, StuName, StuEnName, StuAge, StuBirthday, StuSex,
          Height, Remark )
OUTPUT  Inserted.StuID
VALUES  ( \'010\', -- StuID - varchar(10)
          3, -- Class - int
          N\'叮当\', -- StuName - nvarchar(50)
          \'DingDang\', -- StuEnName - varchar(50)
          22, -- StuAge - int
          GETDATE(), -- StuBirthday - datetime
          N\'男\', -- StuSex - nvarchar(10)
          190, -- Height - int
          \'test\'  -- Remark - text
          )

		  
--4 ,OUTPUT 抛出写入的另外一张物理表中（历史表）
DECLARE @stuIdTable  TABLE(id INT)
INSERT  dbo.Student
        ( StuID, Class, StuName, StuEnName, StuAge, StuBirthday, StuSex,
          Height, Remark )
OUTPUT  Inserted.StuID INTO @stuIdTable  -- OUTPUT INTO只能写入表中
VALUES  ( \'012\', -- StuID - varchar(10)
          3, -- Class - int
          N\'Vanilla\', -- StuName - nvarchar(50)
          \'香草\', -- StuEnName - varchar(50)
          22, -- StuAge - int
          GETDATE(), -- StuBirthday - datetime
          N\'男\', -- StuSex - nvarchar(10)
          190, -- Height - int
          \'test\'  -- Remark - text
          )
SELECT * FROM @stuIdTable

-- 5，更新数据
UPDATE dbo.Student SET Height=Height+10 WHERE Height IS NOT NULL

-- 6, 根据另外一张表进行数据更新:在两个表建立关系的情况下进行更新
-- Join的方式进行多表更新
UPDATE T 
SET T.Remark = \'班级01的学生\' 
FROM dbo.Student AS T  JOIN dbo.ClassInfo AS C
ON t.Class=c.ID WHERE C.ID=\'1\'
-- Where的方式进行多表更新
UPDATE T 
SET T.Remark = \'班级02的学生\' 
FROM dbo.Student AS T  , dbo.ClassInfo AS C
where t.Class=c.ID and C.ID=\'2\'

-- 7， OUTPUT查看更新前、后的数据
UPDATE dbo.Student SET StuSex=\'女\'
 OUTPUT Inserted.StuSex,Deleted.StuSex
WHERE StuID=\'007\'

-- 8, Update中Set语句后的命令是同时执行的，没有先后顺序
UPDATE dbo.Student SET StuSex=\'男\',StuName=StuName+\'-\'+StuSex
WHERE  StuID=\'007\'
SELECT * FROM dbo.Student  WHERE  StuID=\'007\'
   -- 两个字段进行值的互换
UPDATE dbo.Student SET StuAge=Height,Height=StuAge
WHERE  StuID=\'007\'
SELECT * FROM dbo.Student  WHERE  StuID=\'007\'

-- 9, Delete
SELECT * INTO Student_His FROM dbo.Student WHERE 1=2

DELETE dbo.Student 
OUTPUT Deleted.StuID,Deleted.Class,Deleted.StuName,Deleted.StuEnName,Deleted.StuBirthday,Deleted.StuSex,Deleted.Height,Deleted.Remark
INTO dbo.Student_His( StuID,Class,StuName,StuEnName,StuBirthday,StuSex,Height,Remark)
WHERE  StuID=\'007\'

--10, Truncate Table = delete tablename (不带任何条件)：清空表，重置自增列，日志小，操作更快
TRUNCATE TABLE dbo.Student_His 
SELECT *  FROM  [dbo].[Student_His]
