为什么配置单元在 group by 中要求我的变量？简单的情况下

Question

当我运行下面的配置单元查询时，我收到以下错误：编译语句时出错： FAILED: SemanticException [Error 10025]: line 8:13 Expression not in GROUP BY key '50000'

配置单元查询：

SELECT 
    202106 as ANOMES,
    count(wrin_agctd) as QTDETransacoes,
    tipo_transacao,
    cod_cate_cont,
    wrin_nterm,
    case 
        when wrin_valor<50000 then '<500'
        when wrin_valor<100000 then '<1000'
        when wrin_valor<150000 then '<1500'
        when wrin_valor<200000 then '<2000'
    end as test
FROM 
    ghp00468.raultav_saque_conta_salario_tecban_202106
WHERE
    tipo_transacao="SAQUE_TECBAN" and
    tipo_transacao="CONSULTA_TECBAN"
GROUP BY 
    tipo_transacao,
    cod_cate_cont,
    wrin_nterm;

哪里出了问题，出了什么问题？

Answer 1

问题是你的案例陈述。列 test 不在 group by 语句中。您应该将案例陈述添加到分组依据中，或者在分组依据外部处理它。
