  备份处理的存储过程

  set ANSI_NULLS ON

  set QUOTED_IDENTIFIER ON

  go

  /*--备份所有数据库

  备份的文件名为数据库名+日期+.bak

  将所有的用户数据库(或指定的数据库列表)

  备分到指定的目录下.

  /*--调用示例

  --备份所有用户数据库

  exec p_backupdb @bkpath='D:',@dbname=''

  --备份指定数据库

  exec p_backupdb @bkpath=D:',@dbname='数据库名称'

  --*/

  create proc [dbo].[p_backupdb]

  @bkpath nvarchar(260)='D:', --备份文件的存放目录,不指定则使用SQL默认的备份目录

  @dbname nvarchar(4000)='' --要备份的数据库名称列表,不指定则备份所有用户数据库

  as

  declare @sql varchar(8000)

  DECLARE @strdate NVARCHAR(200)

  set @strdate = convert(NVARCHAR(10),getdate(),120)

  set @strdate = REPLACE(@strdate, '-' , '')

  --检查参数

  if isnull(@bkpath,'')=''

  begin

  select @bkpath=rtrim(reverse(filename)) from master..sysfiles where

  select @bkpath=substring(@bkpath,charindex('',@bkpath)+1,4000)

  ,@bkpath=reverse(substring(@bkpath,charindex('',@bkpath),4000))+'BACKUP'

  end

  else if right(@bkpath,1)'' set @bkpath=@bkpath+''

  --得到要备份的数据库列表

  if isnull(@dbname,'')=''

  declare tb cursor local for

  select name from master..sysdatabases where name not in('master','tempdb','model','msdb')

  else

  declare tb cursor local for

  select name from master..sysdatabases

  where name not in('master','tempdb','model','msdb') and(name like '%'+@dbname+'%')

  --备份处理

  open tb

  fetch next from tb into @dbname

  while @@fetch_status=0

  begin

  set @sql='backup database '+@dbname

  +' to disk='''+@bkpath+@dbname +'_'+@strdate

  +'.bak'' with format'

  exec(@sql)

  fetch next from tb into @dbname

  end

  close tb

  deallocate tb

  go

MySQL: String Data Types and Indexing: Best PracticesMySQL: String Data Types and Indexing: Best PracticesMay 12, 2025 am 12:11 AM

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.
