我现在有一张商品的明细表,总共有一百种商品。我现在有每日的商品销售数据,我现在需要通过可视化查询功能,挑选字段:日期、商品、销售量、排名。排名为新建计算字段表达式:row_number() over(order by 销售量 desc )。但是给我报错,You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(order by T1951.`column19` desc ) as `F115732` from `datamanager_datamaintenan' at line 1。
服务器使用的数据库是SQL sever2012,smartbi版本为v8.56
