使用逗号连接下拉列表中选择的所有值。然后将此连接值传递给存储过程中的参数。在查询中分配此参数如下

 选择 * 来自< table_name> 其中< column_name>  （ @ parameter ）< / column_name>< / table_name> 

希望这有帮助

 声明  @ var   varchar （  200 ）= ' ''rs001''，'' am001''' 

 Exec （' 从Emp_Master中选择*，其中empcode为IN（' +  @ var  + ' ）'）

试试这个，希望它会帮助你！

这是一篇很棒的文章来做你想要的。

Concatenate all the values selected in the Dropdown using comma. Then pass this concatenated value to the parameter in the stored procedure. In the query assign this parameter as below

Select * from <table_name> Where <column_name> in (@parameter)</column_name></table_name>

Hope this helps

declare @var varchar(200)=' ''rs001'',''am001'' '

Exec ('select * from Emp_Master where empcode IN (' + @var + ')')
