怎么新建MySQL数据库

本文实例讲述了SQL Server实现将特定字符串拆分并进行插入操作的方法。分享给大家供大家参考，具体如下：

--循环执行添加操作
declare @idx as int
While Len(@UserList) > 0
Begin
  Set @idx = Charindex(',', @UserList);
  --只有一条数据
  If @idx = 0 and Len(@UserList) > 0
Begin
Insert Into BIS_MsgCenterInfo(ID,MsgID,UserID,[State])Values(Newid(),@ID,@UserList,0);
Break;
End
--多条数据
  If @idx > 1
Begin
Insert Into BIS_MsgCenterInfo(ID,MsgID,UserID,[State]) Values(Newid(),@ID,left(@UserList, @idx - 1),0);
Set @UserList = right(@UserList, Len(@UserList) - @idx);
End 
  Else
    Set @UserList = right(@UserList, Len(@UserList) - @idx);
End
