最近在一个做企业的一个内部系统,数据库采用的是SQL2000,,为了保证数据的安全性,需要每天下班之后做数据备份,并且通过邮件的方式通知管理员备份情况。备份数据库很简单,用SQL代理建立一个作业,每天定时备份数据库即可,通过SQL2000来发邮件的话,在网上找了些资料,发现有多种方式可以采用。
一、通过SQL Mail
SQL Mail 提供了一种从 Microsoft SQL Server 发送和阅读电子邮件的简单方法。原理是通过调用服务器上面的 MAPI 子系统来进行邮件发送,所以服务器上面需要安装诸如 Microsoft Outlook(不能是Outlook ExPRess) 之类的 MAPI 客户端,而且在发送邮件的时候,Outlook必须处于打开的状态。具体的设置方法可以通过网上查询。
二、使用CDONTS
通过调用本机的SMTP服务来发送邮件,所以服务器上必须安装IIS和SMTP。相应的存储过程为
CREATE PROCEDURE [dbo].[sp_send_cdontsmail]
@From varchar(100),
@To varchar(100),
@Subject varchar(100),
@Body varchar(4000),
@CC varchar(100) = null,
@BCC varchar(100) = null
AS
Declare @MailID int
Declare @hr int
EXEC @hr = sp_OACreate 'CDONTS.NewMail', @MailID OUT
EXEC @hr = sp_OASetProperty @MailID, 'From',@From
EXEC @hr = sp_OASetProperty @MailID, 'Body', @Body
EXEC @hr = sp_OASetProperty @MailID, 'BCC',@BCC
EXEC @hr = sp_OASetProperty @MailID, 'CC', @CC
EXEC @hr = sp_OASetProperty @MailID, 'Subject', @Subject
EXEC @hr = sp_OASetProperty @MailID, 'To', @To
EXEC @hr = sp_OAMethod @MailID, 'Send', NULL
EXEC @hr = sp_OADestroy @MailID
调用方法:
exec sp_send_cdontsmail 'someone@shouji138.com','someone2@hks8.com','测试邮件标题','这里是邮件内容,推荐一个好的小说站,好看书吧,'
三、使用CDOSYS
微软已经在 Windows 2000、Windows xp 以及 Windows 2003 中淘汰了 CDONTS,所以使用CDOSYS是目前最好的解决方案。使用CDOSYS可以使用远程的SMTP服务器来发送邮件,我们通过测试163网易的免费邮箱,可以正常发送邮件,相应的存储过程如下:
CREATE PROCEDURE sys_sendmail @To varchar(100) , @Bcc varchar(500), @Subject varchar(400)=" ",
@Body varchar(4000) =" "
AS
Declare @smtpserver varchar(50) --SMTP服务器地址
Declare @smtpusername varchar(50) --SMTP服务器用户名
Declare @smtpuserpassWord varchar(50) --SMTP服务器密码
set @smtpserver = 'smtp.163.com'
set @smtpusername = 'yourname@163.com' --这里设置成你的163邮箱用户名
set @smtpuserpassword = 'password' --这里设置成你的163邮箱密码
Declare @object int
Declare @hr int
EXEC @hr = sp_OACreate 'CDO.Message', @object OUT
EXEC @hr = sp_OASetProperty @object, 'Configuration.fields("").Value','2'
EXEC @hr = sp_OASetProperty @object, 'Configuration.fields("").Value', @smtpserver
--下面三条语句是smtp验证,如果服务器需要验证,则必须要这三句,你需要修改用户名和密码
EXEC @hr = sp_OASetProperty @object, 'Configuration.fields("").Value','1'
EXEC @hr = sp_OASetProperty @object, 'Configuration.fields("").Value',@smtpusername
EXEC @hr = sp_OASetProperty @object, 'Configuration.fields("").Value',@smtpuserpassword
EXEC @hr = sp_OAMethod @object, 'Configuration.Fields.Update', null
EXEC @hr = sp_OASetProperty @object, 'To', @To
EXEC @hr = sp_OASetProperty @object, 'Bcc', @Bcc
EXEC @hr = sp_OASetProperty @object, 'From', @smtpusername
EXEC @hr = sp_OASetProperty @object, 'Subject', @Subject
EXEC @hr = sp_OASetProperty @object, 'TextBody', @Body
EXEC @hr = sp_OAMethod @object, 'Send', NULL
--判断出错
IF @hr 0
BEGIN
EXEC sp_OAGetErrorInfo @object
print 'failed'
return @object
END
PRINT 'success'
EXEC @hr = sp_OADestroy @object
GO
调用存储过程发送邮件:exec sys_sendmail 'someone@shouji138.com','someone2@hks8.com','测试邮件标题','这里是邮件内容,手机主题,'
从以上三种方法的优缺点比较来看,我们当然采取第三种方法,不需要在服务器上装别的组件和程序。我们可以在SQL代理中建立一个作业,调度设为每天下午6点,执行的数据库备份语句和发送邮件的SQL如下:
declare @dbname varchar(50)
set @dbname = 'dbtest' --设置数据库名
declare @filename nvarchar(100)
declare @time datetime
set @time = getdate()
set @filename= 'D:数据库自动备份'+@dbname+substring(replace(replace(replace(CONVERT(varchar, @time, 120 ),'-',''),' ',''),':',''),1,14 )+'.bak'
--print @filename
BACKUP DATABASE dbtest TO DISK = @filename WITH NOINIT, NOUNLOAD, NAME = N'BIS_data_backup', NOSKip , STATS = 10, NOFORMAT
--下面获取备份之后文件的大小
declare @size int
declare @sizeM decimal (5, 2)
select top 1 @size=backup_size
from msdb.dbo.backupset
where database_name = @dbname
order by backup_start_date desc
set @sizeM = CAST(@size as float)/1024/1024
--print @sizeM
--邮件内容
declare @content varchar(2000)
set @content='数据库自动备份成功。
数据库名:'+@dbname+'
备份文件名:'+@filename+'
备份文件大小:'+convert(varchar,@sizeM)+'M
备份时间:'+CONVERT(varchar, @time, 120 )+'
这是一封系统自动发出的邮件,用来每天报告数据库自动备份情况,请不要直接回复。'
--print @content
--发送邮件
EXECUTE dbtest.dbo.sys_sendmail 'dba@hks8.com','dba@shouji138.com',
'数据库自动备份日报',@content
go

MySQL uses a GPL license. 1) The GPL license allows the free use, modification and distribution of MySQL, but the modified distribution must comply with GPL. 2) Commercial licenses can avoid public modifications and are suitable for commercial applications that require confidentiality.

The situations when choosing InnoDB instead of MyISAM include: 1) transaction support, 2) high concurrency environment, 3) high data consistency; conversely, the situation when choosing MyISAM includes: 1) mainly read operations, 2) no transaction support is required. InnoDB is suitable for applications that require high data consistency and transaction processing, such as e-commerce platforms, while MyISAM is suitable for read-intensive and transaction-free applications such as blog systems.

In MySQL, the function of foreign keys is to establish the relationship between tables and ensure the consistency and integrity of the data. Foreign keys maintain the effectiveness of data through reference integrity checks and cascading operations. Pay attention to performance optimization and avoid common errors when using them.

There are four main index types in MySQL: B-Tree index, hash index, full-text index and spatial index. 1.B-Tree index is suitable for range query, sorting and grouping, and is suitable for creation on the name column of the employees table. 2. Hash index is suitable for equivalent queries and is suitable for creation on the id column of the hash_table table of the MEMORY storage engine. 3. Full text index is used for text search, suitable for creation on the content column of the articles table. 4. Spatial index is used for geospatial query, suitable for creation on geom columns of locations table.

The main difference between MySQL and SQLite is the design concept and usage scenarios: 1. MySQL is suitable for large applications and enterprise-level solutions, supporting high performance and high concurrency; 2. SQLite is suitable for mobile applications and desktop software, lightweight and easy to embed.

Indexes in MySQL are an ordered structure of one or more columns in a database table, used to speed up data retrieval. 1) Indexes improve query speed by reducing the amount of scanned data. 2) B-Tree index uses a balanced tree structure, which is suitable for range query and sorting. 3) Use CREATEINDEX statements to create indexes, such as CREATEINDEXidx_customer_idONorders(customer_id). 4) Composite indexes can optimize multi-column queries, such as CREATEINDEXidx_customer_orderONorders(customer_id,order_date). 5) Use EXPLAIN to analyze query plans and avoid

Using transactions in MySQL ensures data consistency. 1) Start the transaction through STARTTRANSACTION, and then execute SQL operations and submit it with COMMIT or ROLLBACK. 2) Use SAVEPOINT to set a save point to allow partial rollback. 3) Performance optimization suggestions include shortening transaction time, avoiding large-scale queries and using isolation levels reasonably.
