MSSQL储存过程(转)

1、系统自带储存过程。

 1 exec sp_databases; --查看数据库
 2 exec sp_tables;        --查看表
 3 exec sp_columns student;--查看列
 4 exec sp_helpIndex student;--查看索引
 5 exec sp_helpConstraint student;--约束
 6 exec sp_stored_procedures;
 7 exec sp_helptext 'sp_stored_procedures';--查看存储过程创建、定义语句
 8 exec sp_rename student, stuInfo;--修改表、索引、列的名称
 9 exec sp_renamedb myTempDB, myDB;--更改数据库名称
10 exec sp_defaultdb 'master', 'myDB';--更改登录名的默认数据库
11 exec sp_helpdb;--数据库帮助,查询数据库信息
12 exec sp_helpdb master;

示例:

 1 --表重命名
 2 exec sp_rename 'stu', 'stud';
 3 select * from stud;
 4 --列重命名
 5 exec sp_rename 'stud.name', 'sName', 'column';
 6 exec sp_help 'stud';
 7 --重命名索引
 8 exec sp_rename N'student.idx_cid', N'idx_cidd', N'index';
 9 exec sp_help 'student';
10 
11 --查询所有存储过程
12 select * from sys.objects where type = 'P';
13 select * from sys.objects where type_desc like '%pro%' and name like 'sp%';

2、用户自定义存储过程。

(1)语法。

1 create proc | procedure pro_name
2     [{@参数数据类型} [=默认值] [output],
3      {@参数数据类型} [=默认值] [output],
4      ....
5     ]
6 as
7     SQL_statements

(2)创建不带参数存储过程。

1 if (exists (select * from sys.objects where name = 'proc_get_student'))
2     drop proc proc_get_student
3 go
4 create proc proc_get_student
5 as
6     select * from student;
7 
8 --调用、执行存储过程
9 exec proc_get_student;

(3) 修改存储过程。

1 alter proc proc_get_student
2 as
3 select * from student;

(4)带参存储过程。

1 if (object_id('proc_find_stu', 'P') is not null)
2     drop proc proc_find_stu
3 go
4 create proc proc_find_stu(@startId int, @endId int)
5 as
6     select * from student where id between @startId and @endId
7 go
8 
9 exec proc_find_stu 2, 4;

(5)带通配符参数存储过程。

 1 if (object_id('proc_findStudentByName', 'P') is not null)
 2     drop proc proc_findStudentByName
 3 go
 4 create proc proc_findStudentByName(@name varchar(20) = '%j%', @nextName varchar(20) = '%')
 5 as
 6     select * from student where name like @name and name like @nextName;
 7 go
 8 
 9 exec proc_findStudentByName;
10 exec proc_findStudentByName '%o%', 't%';

(6)带输出参数存储过程。

 1 if (object_id('proc_getStudentRecord', 'P') is not null)
 2     drop proc proc_getStudentRecord
 3 go
 4 create proc proc_getStudentRecord(
 5     @id int, --默认输入参数
 6     @name varchar(20) out, --输出参数
 7     @age varchar(20) output--输入输出参数
 8 )
 9 as
10     select @name = name, @age = age  from student where id = @id and sex = @age;
11 go
12 
13 -- 
14 declare @id int,
15         @name varchar(20),
16         @temp varchar(20);
17 set @id = 7; 
18 set @temp = 1;
19 exec proc_getStudentRecord @id, @name out, @temp output;
20 select @name, @temp;
21 print @name + '#' + @temp;

(7)不缓存存储过程。

 1 --WITH RECOMPILE 不缓存
 2 if (object_id('proc_temp', 'P') is not null)
 3     drop proc proc_temp
 4 go
 5 create proc proc_temp
 6 with recompile
 7 as
 8     select * from student;
 9 go
10 
11 exec proc_temp;

(8)加密存储过程。

 1 if (object_id('proc_temp_encryption', 'P') is not null)
 2     drop proc proc_temp_encryption
 3 go
 4 create proc proc_temp_encryption
 5 with encryption
 6 as
 7     select * from student;
 8 go
 9 
10 exec proc_temp_encryption;
11 exec sp_helptext 'proc_temp';
12 exec sp_helptext 'proc_temp_encryption';

(9)带游标参数存储过程。

 1 if (object_id('proc_cursor', 'P') is not null)
 2     drop proc proc_cursor
 3 go
 4 create proc proc_cursor
 5     @cur cursor varying output
 6 as
 7     set @cur = cursor forward_only static for
 8     select id, name, age from student;
 9     open @cur;
10 go
11 --调用
12 declare @exec_cur cursor;
13 declare @id int,
14         @name varchar(20),
15         @age int;
16 exec proc_cursor @cur = @exec_cur output;--调用存储过程
17 fetch next from @exec_cur into @id, @name, @age;
18 while (@@fetch_status = 0)
19 begin
20     fetch next from @exec_cur into @id, @name, @age;
21     print 'id: ' + convert(varchar, @id) + ', name: ' + @name + ', age: ' + convert(char, @age);
22 end
23 close @exec_cur;
24 deallocate @exec_cur;--删除游标

(10)分页存储过程。

 1 if (object_id('pro_page', 'P') is not null)
 2     drop proc proc_cursor
 3 go
 4 create proc pro_page
 5     @startIndex int,
 6     @endIndex int
 7 as
 8     select count(*) from product
 9 ;    
10     select * from (
11         select row_number() over(order by pid) as rowId, * from product 
12     ) temp
13     where temp.rowId between @startIndex and @endIndex
14 go
15 --drop proc pro_page
16 exec pro_page 1, 4
17 --
18 --分页存储过程
19 if (object_id('pro_page', 'P') is not null)
20     drop proc pro_stu
21 go
22 create procedure pro_stu(
23     @pageIndex int,
24     @pageSize int
25 )
26 as
27     declare @startRow int, @endRow int
28     set @startRow = (@pageIndex - 1) * @pageSize +1
29     set @endRow = @startRow + @pageSize -1
30     select * from (
31         select *, row_number() over (order by id asc) as number from student 
32     ) t
33     where t.number between @startRow and @endRow;
34 
35 exec pro_stu 2, 2;
