前些天发现了一个巨牛的人工智能学习网站，通俗易懂，风趣幽默，忍不住分享一下给大家。点击跳转到教程。

1.报错：

Error while compiling statement: FAILED: SemanticException [Error 10007]: Ambiguous column reference creationtime in bcpt

2. sql如下：

insert overwrite table z_w_clean.di_tets_e_typeSELECT cont_pr_code,plurt_code,elec_e_code,cont_price_name,pre,creadate,ste,creationtime,ornizeid,cont_free,is_frlevy,bace_limit,creationtime,creorid,null,liicatiotime,lasmoerid,nullFROM (SELECT contce_code,plusort_coe,eleype_code,contrice_name,pice,cte_date,sate,fr_type,orgzeid,con_free,iee_levy,ballimit,From_unixtime(Unix_timestamp(creationtime)) AS creationtime,crearid,null,From_unixtime(Unix_timestamp(lastmontime)) AS lastationtime,lastmoid,null,Row_number() OVER(partition BY contece_code ORDER BY ontime DESC) AS numFROM s_wter.buients_prce_pe) bbbWHERE bbb.num = 1;

3.报错原因：有重复定义的列: creationtime , 改名解决 。
