一般分为十种情况,每种语法各不相同:
1、 创建语法
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
--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
--修改存储过程 alter proc proc_get_student as select * from student; |
4、 带参存储过程
--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
--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
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
--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
--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 sp_helptext 'proc_temp' ; exec sp_helptext 'proc_temp_encryption' ; |
9、 带游标参数存储过程
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 (@@fetch_status = 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
---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;
