Question

我正在尝试在Pentaho Report Designer中创建我的第一份报告。我创建了一个JDBC数据源并添加了一个查询：

SELECT a.* 
FROM   (SELECT Sum(loan_receivable_detail.interest) AS interest, 
               loan_account_opening_id 
        FROM   loan_receivable_detail 
        GROUP  BY loan_account_opening_id) AS a

但是，当我保存查询时，它会更改为：

SELECT
     a.*,
     sum(loan_receivable_detail.interest) AS interest,
     loan_account_opening_id AS interest
FROM
     `loan_receivable_detail`
GROUP BY
     loan_account_opening_id,
     as,
     a

我的查询中是否有任何问题导致其更改？该语法在其他查询分析器中运行良好......

Answer 1

您的查询应该有效，但似乎Pentaho在解析它时遇到了问题。

您可以尝试使用

SELECT SUM(loan_receivable_detail.interest) AS interest, 
               loan_account_opening_id 
        FROM   loan_receivable_detail 
        GROUP  BY loan_account_opening_id

它提供与查询相同的结果但没有子查询（希望它会让Pentaho满意）
