sql存儲過程帶in條件的解決方法

sql存儲過程帶in條件的解決方法

問題：

if (object_id('procedure_table', 'P') is not null)

    drop proc procedure_table

go

    create proc procedure_table(@isdelete int, @id varchar(20))

as

    select * from tableName where isdelete = @isdelete and id in (@id);

go

上存儲過程在執行後沒有查到任何東西，原因是存儲過程将@id當作一個參數，而不是字元串拼接，是以如果id有幾個的話，那麼後面的語句就是id in ('1,2,3') ，故查不到資料。

解決方法：（拼接Sql語句）

if (object_id('procedure_table', 'P') is not null)

    drop proc procedure_table

go

    create proc procedure_table(@isdelete int, @id varchar(20))

as

    exec ('select * from tableName where isdelete = ' + @isdelete + ' and id in ( '+ @id + ' )')

go

exec procedure_table 0,'1,2,3'

--------------------------更多存儲過程知識---------------------------------

Ø 使用者自定義存儲過程

   1、 建立文法

create proc | procedure pro_name
    [{@參數資料類型} [=預設值] [output],
     {@參數資料類型} [=預設值] [output],
     ....
    ]
as
    SQL_statements
      

   2、 建立不帶參數存儲過程

--建立存儲過程
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;

--調用、執行存儲過程
exec proc_get_student;
      

   3、 修改存儲過程

--修改存儲過程
alter proc proc_get_student
as
select * from student;
      

   4、 帶參存儲過程

--帶參存儲過程
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、 帶通配符參數存儲過程

--帶通配符參數存儲過程
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、 帶輸出參數存儲過程

if (object_id('proc_getStudentRecord', 'P') is not null)
    drop proc proc_getStudentRecord
go
create proc proc_getStudentRecord(
    @id int, --預設輸入參數
    @name varchar(20) out, --輸出參數
    @age varchar(20) output--輸入輸出參數
)
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、 不緩存存儲過程

--WITH RECOMPILE 不緩存
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、 加密存儲過程

--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';
