一般分为十种情况,每种语法各不相同:
1、 创建语法
| 1 2 3 4 5 6 7 |
create proc | procedure pro_name
[{@参数数据类型} [=默认值] [output],
{@参数数据类型} [=默认值] [output],
....
]
as
SQL_statements
|
2、 创建不带参数存储过程
| 1 2 3 4 5 6 7 8 9 10 |
--创建存储过程
if (exists (select * from sys.objects where name = ‘proc_get_student‘))
drop proc proc_get_student
go
create proc proc_get_student
as
select * from student;
--调用、执行存储过程
exec proc_get_student;
|
3、 修改存储过程
| 1 2 3 4 |
--修改存储过程
alter proc proc_get_student
as
select * from student;
|
4、 带参存储过程
| 1 2 3 4 5 6 7 8 9 10 |
--带参存储过程
if (object_id(‘proc_find_stu‘, ‘P‘) is not null)
drop proc proc_find_stu
go
create proc proc_find_stu(@startId int, @endId int)
as
select * from student where id between @startId and @endId
go
exec proc_find_stu 2, 4;
|
5、 带通配符参数存储过程
| 1 2 3 4 5 6 7 8 9 10 11 |
--带通配符参数存储过程
if (object_id(‘proc_findStudentByName‘, ‘P‘) is not null)
drop proc proc_findStudentByName
go
create proc proc_findStudentByName(@name varchar(20) = ‘%j%‘, @nextName varchar(20) = ‘%‘)
as
select * from student where name like @name and name like @nextName;
go
exec proc_findStudentByName;
exec proc_findStudentByName ‘%o%‘, ‘t%‘;
|
6、 带输出参数存储过程
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
if (object_id(‘proc_getStudentRecord‘, ‘P‘) is not null)
drop proc proc_getStudentRecord
go
create proc proc_getStudentRecord(
@id int, --默认输入参数
@name varchar(20) out, --输出参数
@age varchar(20) output--输入输出参数
)
as
select @name = name, @age = age from student where id = @id and sex = @age;
go
--
declare @id int,
@name varchar(20),
@temp varchar(20);
set @id = 7;
set @temp = 1;
exec proc_getStudentRecord @id, @name out, @temp output;
select @name, @temp;
print @name + ‘#‘ + @temp;
|
7、 不缓存存储过程
| 1 2 3 4 5 6 7 8 9 10 11 |
--WITH RECOMPILE 不缓存
if (object_id(‘proc_temp‘, ‘P‘) is not null)
drop proc proc_temp
go
create proc proc_temp
with recompile
as
select * from student;
go
exec proc_temp;
|
8、 加密存储过程
| 1 2 3 4 5 6 7 8 9 10 11 12 13 |
--加密WITH ENCRYPTION
if (object_id(‘proc_temp_encryption‘, ‘P‘) is not null)
drop proc proc_temp_encryption
go
create proc proc_temp_encryption
with encryption
as
select * from student;
go
exec proc_temp_encryption;
exec <a href="https://www.baidu.com/s?wd=sp_helptext&tn=44039180_cpr&fenlei=mv6quAkxTZn0IZRqIHckPjm4nH00T1YYm103n1DYmHfknhD3nWD10ZwV5Hcvrjm3rH6sPfKWUMw85HfYnjn4nH6sgvPsT6KdThsqpZwYTjCEQLGCpyw9Uz4Bmy-bIi4WUvYETgN-TLwGUv3EPW63nHcdrH6" target="_blank" class="baidu-highlight">sp_helptext</a> ‘proc_temp‘;
exec <a href="https://www.baidu.com/s?wd=sp_helptext&tn=44039180_cpr&fenlei=mv6quAkxTZn0IZRqIHckPjm4nH00T1YYm103n1DYmHfknhD3nWD10ZwV5Hcvrjm3rH6sPfKWUMw85HfYnjn4nH6sgvPsT6KdThsqpZwYTjCEQLGCpyw9Uz4Bmy-bIi4WUvYETgN-TLwGUv3EPW63nHcdrH6" target="_blank" class="baidu-highlight">sp_helptext</a> ‘proc_temp_encryption‘;
|
9、 带游标参数存储过程
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |
if (object_id(‘proc_cursor‘, ‘P‘) is not null)
drop proc proc_cursor
go
create proc proc_cursor
@cur cursor varying output
as
set @cur = cursor forward_only static for
select id, name, age from student;
open @cur;
go
--调用
declare @exec_cur cursor;
declare @id int,
@name varchar(20),
@age int;
exec proc_cursor @cur = @exec_cur output;--调用存储过程
fetch next from @exec_cur into @id, @name, @age;
while (<a href="https://www.baidu.com/s?wd=%40%40fetch_status&tn=44039180_cpr&fenlei=mv6quAkxTZn0IZRqIHckPjm4nH00T1YYm103n1DYmHfknhD3nWD10ZwV5Hcvrjm3rH6sPfKWUMw85HfYnjn4nH6sgvPsT6KdThsqpZwYTjCEQLGCpyw9Uz4Bmy-bIi4WUvYETgN-TLwGUv3EPW63nHcdrH6" target="_blank" class="baidu-highlight">@@fetch_status</a> = 0)
begin
fetch next from @exec_cur into @id, @name, @age;
print ‘id: ‘ + convert(varchar, @id) + ‘, name: ‘ + @name + ‘, age: ‘ + convert(char, @age);
end
close @exec_cur;
deallocate @exec_cur;--删除游标

10、 分页存储过程
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 |
---存储过程、row_number完成分页
if (object_id(‘pro_page‘, ‘P‘) is not null)
drop proc proc_cursor
go
create proc pro_page
@startIndex int,
@endIndex int
as
select count(*) from product
;
select * from (
select row_number() over(order by pid) as rowId, * from product
) temp
where temp.rowId between @startIndex and @endIndex
go
--drop proc pro_page
exec pro_page 1, 4
--
--分页存储过程
if (object_id(‘pro_page‘, ‘P‘) is not null)
drop proc pro_stu
go
create procedure pro_stu(
@pageIndex int,
@pageSize int
)
as
declare @startRow int, @endRow int
set @startRow = (@pageIndex - 1) * @pageSize +1
set @endRow = @startRow + @pageSize -1
select * from (
select *, row_number() over (order by id asc) as number from student
) t
where t.number between @startRow and @endRow;
exec pro_stu 2, 2;
