trigger中insert动作的测试

Trigger为默认事务

测试环境：sql server 2008 r2

对象：DevList表

目标：确定trigger在数据库中有数据变化时是一次一批一批执行还是，按每条触发执行

测试需求：

DevList的触发器

CREATE TRIGGER dbo.Test

ON  DevList

AFTER insert

AS

BEGIN

SET NOCOUNT ON;

-- Insert statements for trigger here

--修改Table_Test数量+1

update Table_Test set [No]=[No]+1

END

GO

表Table_Test：

CREATE TABLE [dbo].[Table_Test](

[No] [int] NULL

) ON [PRIMARY]

用例：

一、使用insert语句想DevList中插入数据，本次不用事务，不用存储过程，同时执行10条insert语句

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.45','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.46','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.47','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.48','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.49','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.50','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.51','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.52','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.53','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.54','aaaaa','bbbbb','ccccc',0,0)

二、在存储过程中使用10条insert语句，本次不用事务

SET ANSI_NULLS ON

GO

SET QUOTED_IDENTIFIER ON

GO

-- =============================================

-- Author:         <Author,,Name>

-- Create date: <Create Date,,>

-- Description:    <Description,,>

-- =============================================

CREATE PROCEDURE dbo.NoTranTest

AS

BEGIN

-- SET NOCOUNT ON added to prevent extra result sets from

-- interfering with SELECT statements.

SET NOCOUNT ON;

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.55','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.56','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.57','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.58','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.59','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.60','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.61','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.62','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.63','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.64','aaaaa','bbbbb','ccccc',0,0)

END

GO

三、在存储过程中使用10条insert语句，本次使用事务

SET ANSI_NULLS ON

GO

SET QUOTED_IDENTIFIER ON

CREATE PROCEDURE dbo.TranTest

AS

BEGIN

-- SET NOCOUNT ON added to prevent extra result sets from

-- interfering with SELECT statements.

SET NOCOUNT ON;

---开启事务

begin tran

--错误扑捉机制，看好啦，这里也有的。并且可以嵌套。

begin try

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.75','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.76','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.77','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.78','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.79','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.80','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.81','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.82','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.83','aaaaa','bbbbb','ccccc',0,0)

INSERT INTO [DCMHR].[dbo].[DevList]([ip],[subnet],[gateway],[script],[status],[reccount]) VALUES ('190.10.24.84','aaaaa','bbbbb','ccccc',0,0)

end try

begin catch

--select Error_number() as ErrorNumber,  --错误代码

--       Error_severity() as ErrorSeverity,  --错误严重级别，级别小于try catch 捕获不到

--       Error_state() as ErrorState ,  --错误状态码

--       Error_Procedure() as ErrorProcedure , --出现错误的存储过程或触发器的名称。

--       Error_line() as ErrorLine,  --发生错误的行号

--       Error_message() as ErrorMessage  --错误的具体信息

if(@@trancount>0) --全局变量@@trancount，事务开启此值+1，他用来判断是有开启事务

begin

rollback tran  ---由于出错，这里回滚到开始，

end

end catch

if(@@trancount>0)

begin

commit tran  --如果成功Lives表中，将会有条数据。

end

END

GO

执行测试之前清空DevList表中数据，Table_Test表中第一栏，第一个格设为0

执行情况：

执行用例中一选项，查看Table_Test结果10

执行用例中二选项

Exec NoTranTest

查看Table_Test结果20

执行用例三选项

Exec TranTest

查看Table_Test结果30
