MSSQL记录

批量添加：

DECLARE @GID INT,@UID INT,@Indexs INT
SET @GID=1
SET @UID=37
SET @Indexs=0
WHILE @GID<674 --674要执行插入的次数
BEGIN
INSERT INTO TB_Employee (CompetitionId, UserId,GroupId,GroupSouce,IsAudit,IsFinal ) -- CompetitionUser 为表名
VALUES ( 52, @UID, @GID, 1, 1, 0)
SET @Indexs = @Indexs+1;
SET @UID = @UID+1;
IF(@Indexs=3)
BEGIN
SET @Indexs=0
SET @GID=@GID+1
END
END

条件排序：

select * FROM TB_Employee ORDER BY
case
when Salary = 1200 then 1
when Salary > 1200 then 2
when Salary < 1200 then 3
end,EmployeeId;

select * FROM TB_Employee ORDER BY
case
when Salary in (1200,238) then 1
else 2
end,EmployeeId

--set @CID=1
--set @UID=1
--exec Proc_GetIndexNum @CID,@UID,@NumA out,@NumB out,@NumC out,@NumD out

更改原字段内容：

[通过sql在目标电脑创建文件路径]：

EXEC sp_configure 'show advanced options', 1

GO

RECONFIGURE

GO

EXEC sp_configure 'xp_cmdshell', 1

RECONFIGURE

GO

ExEc xp_cmdshell 'mkdir E:\Aroject' --调用DOS命令创建project文件夹

[获取目标电脑数据库文件存放位置，并在此创建数据库]：

declare  @path  varchar(200)

select  @path  =  filename  from  master.dbo.sysfiles

set  @path  =  ltrim(REVERSE(@path))

set  @path  =  REVERSE(substring(@path,CHARINDEX('\',@path),len(@path)))

exec('CREATE DATABASE xxxx ON PRIMARY (NAME = "xxxx", FILENAME = "' + @path + 'xxxx.mdf", SIZE = 2304KB , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB) LOG ON (NAME = "xxxx_log", FILENAME = "' + @path + 'xxxx.ldf", SIZE = 832KB , MAXSIZE = 2048GB , FILEGROWTH = 10%)')

[如果数据库已存在，关闭数据库连接，并删除数据库]：

declare @i int declare cur cursor for select spid from sysprocesses where db_name(dbid)= 'DB_Test' open cur fetch next from cur into @i while @@fetch_status=0 begin exec('kill '+@i) fetch next from cur into @i end close cur deallocate cur

IF  EXISTS (SELECT name FROM sys.databases WHERE name = N'DB_Test')

DROP DATABASE [DB_Test]
