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; |
