Sql server 使用 in()函数 传递字符串

首先创建一个分隔字符串函数：

create  function  SplitIn(@c   varchar(2000),@split   varchar(2))   
returns   @t   table(col   varchar(20))   
as   
begin    
  while(charindex(@split,@c)<>0)   
    begin   
      insert   @t(col)   values   (substring(@c,1,charindex(@split,@c)-1))   
      set   @c   =   stuff(@c,1,charindex(@split,@c),'')   
    end   
  insert   @t(col)   values   (@c)   
  return   
end

第二，在存储过程中使用SplitIn函数

select @TeamRoomCount = COUNT(Work_GuestAccount.AccountID)  FROM  Work_GuestAccount INNER JOIN 
                Work_GuestEntryIndex ON Work_GuestAccount.EntryID = Work_GuestEntryIndex.EntryID 
                WHERE (Work_GuestEntryIndex.TeamID <> '') AND (Work_GuestEntryIndex.TeamID IS NOT NULL)
                AND (Work_GuestAccount.RoomID IN (select col from SplitIn(@TeamRoomNo,',')))
