Sql server中Collation conflict问题

SQL语句查询时
select A.Code,A.Name,a.Systemcode,B.ID,B.LogType,B.DMCode,B.IP,B.Department,B.CreateBy,B.CreateTime
from DM_Document_TD as A left join DM_LOG_TD as B
on A .Code=B .DMCode

结果在运行时碰到这样一个问题，问题描述：
Cannot resolve the collation conflict between "SQL_Latin1_General_CP1_CI_AS" and "Chinese_PRC_CI_AS" in the equal to operation.
到网上搜了一下，了解了问题产生的原因，原来是两个数据库的collation不一致导致的，将查询语句改成如下：

select A.Code,A.Name,a.Systemcode,B.ID,B.LogType,B.DMCode,B.IP,B.Department,B.CreateBy,B.CreateTime
from DM_Document_TD as A left join DM_LOG_TD as B
on A .Code collate chinese_prc_ci_as =B .DMCode
