抱歉打开这个问题。我想有人告诉我如何归档这个因为ai有同样的问题但我没有得到预期的结果或this问题假设它可能但我不得到同样的。
我将继续我的工作

我还检查了其他来源，如this，但我无法完成目标。所以这是不可能的，或者我做错了？
答案 0 :(得分：0)
如果你不想用参数改变SQL语句，参数的语法有点不同。 在您的示例中，按顺序将订单更改为：
order by $P!{grpHeader}
没有“！”在$ P Jasper将插入格式化的值之后，所以在运行时你会得到像
这样的东西order by "cliente"
而不是
order by cliente
按表达式分组看起来没问题，运行报告时是否会出现任何错误（在更正order by子句后）？
