Hive常见错误
开窗函数执行问题
select mid_id, dt, rank()over(partitionby mid_idorderby dt) rk from(select mid_id, dtfrom dws_uv_detail_daycountwhere dt>=date_add(,-6)groupby mid_id,dt );
运行报错:
org.apache.hadoop.hive.ql.parse.ParseException:line 13:1 cannot recognize input near ‘’ ‘’ ‘’ in subquery source
解决方案
在DG中加一个别名t1就可以执行进行测试
select mid_id, dt, rank()over(partitionby mid_idorderby dt) rk from(select mid_id, dtfrom dws_uv_detail_daycountwhere dt>=date_add(,-6)groupby mid_id,dt )t1;
