好的，所以当我在iReport中运行报告时，我只会得到一行作为输出
100 100 - BA - 7294 - 1 - 3
但是当我从服务器日志中复制报告创建的查询并运行它时，我得到 80 行作为输出
100 100 - BA - 7294 - 1 - 3
100 101 - BA - 7294 - 1 - 3
100 102 - BA - 7294 - 1 - 3
100 103 - BA - 7294 - 1 - 3
100 104 - BA - 7294 - 1 - 3
100 106 - BA - 7294 - 1 - 3
100 107 - BA - 7294 - 1 - 3
100 108 - BA - 7294 - 1 - 3
100 109 - BA - 7294 - 1 - 3
100 110 - BA - 7294 - 1 - 3
etc...
我已经做了一百次这样的报告，这从未发生过，我似乎无法找到解决方案
丢失数据的原因可能是什么？
这是我从日志中复制的查询（这是一个简单的查询，没什么特别的）
