我有这个 sql 语句，旨在对表的总和列求和：
p_id p_name atc_code tax_amt base_amt date
2300 |A student |WC158 - EWT 1% |133.93 |13392.86 |2015-07-01
2300 |A student |WC158 - EWT 1% |62.50 |6250.00 |2015-07-01
901 |B student |WC158 - EWT 1% |8.31 |830.58 |2015-06-09
2831 |C student |WC160 - EWT 2% |2736.84 |136842.11 |2015-06-04
905 |D student |WC158 - EWT 1% |31.25 |3125.00 |2015-06-16
905 |D student |WC158 - EWT 1% |31.25 |3125.00 |2015-06-29
905 |D student |WC158 - EWT 1% |31.25 |3125.00 |2015-06-29
905 |D student |WC158 - EWT 1% |26.79 |2678.57 |2015-06-16
959 |G student |WC158 - EWT 1% |114.29 |11428.57 |2015-01-10
959 |G student |WC158 - EWT 1% |478.90 |47890.18 |2015-01-20
2424 |L student |WC158 - EWT 1% |45.54 |4553.58 |2015-03-03
我也有这个说法。

group by es.partner_id,es.name''',(ewt.date_from,ewt.date_to))
其中ewt.date_from和ewt.date_to是来自用户的输入。我无法理解的是在执行期间（当在我的视图上调用此方法时）它会产生一个错误消息：“IndexError：元组索引超出范围”。这是我在日志中经常看到的，它还说我的查询很糟糕。
group by es.partner_id,es.name''',(ewt.date_from,ewt.date_to))

有谁可以指出我在哪里犯了错误？它真的让我头晕目眩。
