Question

每当我运行此查询时，我总是得到相同的错误。我尝试使用简单的查询来测试查询中是否有错误。我还注意到，当我在查询中使用视图时发生了错误。

创建或替换视图v_vss_car_wash AS

     SELECT
     max(r.id) AS id
    ,d.id AS dealer_id
    ,d.dealer_code
    ,d.dealer_name
    ,count(*) AS total_respondents
    ,sum(car_washed) AS car_washed                  -- Car Washed
    ,count(*) - sum(car_washed) AS car_unwashed     -- Car Unwashed
    ,sum(IF (car_washed AND car_satisfied, 1, 0)) AS car_satisfied
    ,sum(IF (car_washed AND NOT car_satisfied, 1, 0)) AS car_unsatisfied
    ,MONTH(r.create_date) AS create_month
    ,YEAR(r.create_date) AS create_year
FROM t_vss_survey_response r 
    LEFT JOIN t_vss_dealer d ON (r.dealer_id = d.id)
WHERE survey_code = "ASS"
GROUP BY dealer_code, YEAR(r.create_date), MONTH(r.create_date);

然后这是我使用的查询（非常简单），但我总是得到同样的错误。

选择a.dealer_name，a.dealer_code 来自v_vss_car_wash a

现在，这是错误消息

引起：org.eclipse.birt.data.engine.odaconsumer.OdaDataException：无法获取结果集元数据。 org.eclipse.birt.report.data.oda.jdbc.JDBCException： SQL语句不返回ResultSet对象。 SQL错误＃1：'crmsdbdev.d.dealer_name'不在GROUP BY 中 ; com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException：'crmsdbdev.d.dealer_name'不在GROUP BY中

只需将相应的列添加到group by：

即可

CREATE OR REPLACE VIEW v_vss_car_wash AS
SELECT
     max(r.id) AS id
    ,d.id AS dealer_id
    ,d.dealer_code
    ,d.dealer_name
    ,count(*) AS total_respondents
    ,sum(car_washed) AS car_washed                  -- Car Washed
    ,count(*) - sum(car_washed) AS car_unwashed     -- Car Unwashed
    ,sum(IF (car_washed AND car_satisfied, 1, 0)) AS car_satisfied
    ,sum(IF (car_washed AND NOT car_satisfied, 1, 0)) AS car_unsatisfied
    ,MONTH(r.create_date) AS create_month
    ,YEAR(r.create_date) AS create_year
FROM t_vss_survey_response r 
    LEFT JOIN t_vss_dealer d ON (r.dealer_id = d.id)
WHERE survey_code = "ASS"
GROUP BY d.id, d.dealer_code, d.dealer_name,
         YEAR(r.create_date), MONTH(r.create_date);

databasename.d.first_column_in_the_table'不在GROUP BY
