>            Reporter: Jiale He

> h1. 复现步骤：
> 表table1有 a1,a2字段
> 表table2有b1,b2字段
> 创建模型A
> table1.a1=table2.b1
> 创建可计算列
> 名称 b2 表达式 table2.b2
> 选择字段后保存
> 报错
> h1. Root Cause
> 此Bug产生原因是CC列列名和维度表列名一致，导致无限递归
>  
> h1. Fix Design
> 当前解析CC列获取引用的模型列时，将引用列放到Map中的key值为CC列列名，非全名称(column)。而解析出的模型列明为全名称，改为保持一致都是用全名称(database.table.column)来检索，可以避免切割造成列名称冲突。
> cc_name : [database.table.colum1, database.table.colum2] => 改为 database.table.cc_name : [database.table.colum1, database.table.colum2]
> 使用列全名称来进行递归
