sql存储过程带in条件的解决方法

sql存储过程带in条件的解决方法

问题：

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

上存储过程在执行后没有查到任何东西，原因是存储过程将@id当作一个参数，而不是字符串拼接，所以如果id有几个的话，那么后面的语句就是id in ('1,2,3') ，故查不到数据。

解决方法：（拼接Sql语句）

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'

Ø 用户自定义存储过程

   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';
