mysql 使用包含变量的 mysql 查询创建 View

Question

我想使用以下语法来创建 MySQL View :

create view `ViewName` as (select
              v_starting.callingname,
              v_starting.geofence,
              v_starting.`updatetime`,
              @lastGroup := @lastGroup + if( @lastAddress = v_starting.geofence 
                                         AND @lastVehicle = v_starting.callingname, 0, 1 ) as GroupSeq,
              @lastVehicle := v_starting.callingname as justVarVehicleChange,
              @lastAddress := v_starting.geofence as justVarAddressChange
           from
              v_starting,
              ( select @lastVehicle := '',
                       @lastAddress := '',
                       @lastGroup := 0 ) SQLVars

           order by
              v_starting.`updatetime` )

此操作失败并出现错误:

#1351 - View's SELECT contains a variable or parameter

我该如何解决这个问题？谢谢一百万。

如 CREATE VIEW Syntax 下所述:

A view definition is subject to the following restrictions:

[ <strong><em>deletia</em></strong> ]

• The SELECT statement cannot refer to system or user variables.
