最近因为系统需要,需要将master库的所有和业务相关的存储过程批量生成 存储过程名.sql 文件,默认是不可以导出的
大家都知道系统存储过程是无法用工具导出的(大家可以试试 >任务>生成SQL脚本)因为系统存储过程一般是不让开发人员修改的。
需要知识:
1、xp_cmdshell命令的使用
2、sp_MS_marksystemobject 标记系统存储过程的方法
3、dos 命令,如 type,>> 等
4、bcp 命令的使用
代码如下:
use master
go
if OBJECT_ID('pr_procToSql') is not null drop proc pr_procToSql
go
create proc pr_procToSql
(
@服务器名 varchar(100)
,@用户名 varchar(100)
,@密码 varchar(100)
,@path varchar(200)
,@database varchar(200)
,@sysproc int='0' --是否标记为系统函数 1:是,0:否
,@proc_name varchar(100)='' --默认是所有,可以模糊搜索
,@savetype varchar(200)='.sql' --默认保存为sql脚本
)

功能:
1\将master库的系统存储过程批量生成文件(系统存储过程无法自动导出)
2\可以将所有类型的存储过程导出
3\可以标记上系统存储过程
调用:
exec pr_procToSql '.','sa','H4ymH@$RTd','e:\tom\master\','master','1',‘'
exec pr_procToSql '.','sa','a123456','e:\sql\','agt_trad','','pr_','.sql'
*/
set nocount on
declare @sp nvarchar(500),@s nvarchar(2000),@row int,@id int,@s_add varchar(2000)
set @s=' use '+@database
exec(@s)
if object_id('tempdb..#t') is not null drop table tempdb..#t
create table tempdb..#t(name varchar(2000)
, id int IDENTITY(1,1) not null
)
exec('
insert into tempdb..#t(name)
select name
--into TEMPDB..#T
from '+@database+'..sysobjects where xtype=''p'' and name like '''+@proc_name+'%''
')
select @row=COUNT(*) from tempdb..#t
print '共生成['+cast(@row as varchar)+']个存储过程'
set @id=1
while @row>=@id
begin
select top 1 @sp=name from tempdb..#T where id=@id
if OBJECT_ID('tempdb..test') is not null drop table tempdb..test
--增加use master go
set @s_add='echo use ['+@database+']>>'+@path+@sp+@savetype
exec xp_cmdshell @s_add
set @s_add='echo GO>>'+@path+@sp+@savetype
exec xp_cmdshell @s_add
set @s_add='echo IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N''[dbo].['+@sp+']'') AND type in (N''P'', N''PC''))>>'+@path+@sp+@savetype
exec xp_cmdshell @s_add
set @s_add='echo DROP PROCEDURE [dbo].['+@sp+']>>'+@path+@sp+@savetype
exec xp_cmdshell @s_add
set @s_add='echo GO>>'+@path+@sp+@savetype
exec xp_cmdshell @s_add
set @s_add='echo SET ANSI_NULLS ON>>'+@path+@sp+@savetype
exec xp_cmdshell @s_add
set @s_add='echo GO>>'+@path+@sp+@savetype
exec xp_cmdshell @s_add
set @s_add='echo SET QUOTED_IDENTIFIER ON>>'+@path+@sp+@savetype
exec xp_cmdshell @s_add

exec xp_cmdshell @s_add

'
exec(@s)
--select * from tempdb..test
select @s='exec xp_cmdshell '+'''bcp tempdb..test out '+@path+@sp+cast(@id as varchar)+@savetype+' -c -S '+@服务器名+' -U '+@用户名+' -P '+@密码+''''
exec(@s)
--将前面加上use master 信息追加到 最前面
set @s_add='type '+@path+@sp+CAST(@id as varchar)+@savetype+'>>'+@path+@sp+@savetype
exec xp_cmdshell @s_add
set @s_add='echo GO>>'+@path+@sp+@savetype
exec xp_cmdshell @s_add
if @sysproc='1'
begin
--在最后面加上标记为系统存储过程
set @s_add='echo exec sp_MS_marksystemobject ''['+@sp+']''>>'+@path+@sp+@savetype
exec xp_cmdshell @s_add
set @s_add='echo GO>>'+@path+@sp+@savetype
exec xp_cmdshell @s_add
print '标记第['+cast(@id as varchar)+']个为系统存储过程:'+@sp
end
set @s_add='del '+@path+@sp+CAST(@id as varchar)+@savetype
exec xp_cmdshell @s_add
print '生成第['+cast(@id as varchar)+']个存储过程:'+@sp
delete from tempdb..#T where id=@id
set @id=@id+1
end
此存储过程可以完善的功能
1、生成视图
2、生成函数
3、生成指定库的表结构
4、生成指定库的约束,用于批量生成升级脚本
5、用于生成数据库中升级的脚本
欢迎大家帮我想想,还有别的办法吗?希望加QQ282329611交流。
生成结果如图:

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA
