Question

我有一个很好的SQL查询，直到我尝试实现group by子句。目前它正在获取我要求的所有行但是他们需要进行其他明智的分组我有太多的行。但是一旦我添加了一个组，即使它只是按一列分组，sql也会完全崩溃。任何帮助将不胜感激。

SQL的当前错误消息为：

执行数据库查询时出错。

[Macromedia] [SequeLink JDBC驱动程序] [ODBC套接字] [IBM] [iSeries Access ODBC驱动程序] [DB2 UDB] SQL0122 - 列QDSHDT或SELECT列表中的表达式无效。

就像我在没有group by子句时提到的那样，这个错误完全消失了，查询运行正常。
