Jasper reports 使用日期参数时获取错误

我正在使用iReport 5.0.1。我创建了一个日期参数，并在查询中使用它：

预览报告时，我输入日期参数：

输入所有参数并运行报告后，出现以下错误：

这是怎么回事，我该怎么解决？谢谢

我认为

在
$P！{…}
意味着在报告中包含参数的文本值

尝试使用
$p{start\u date}
和
$p{end\u date}
，两者都不带

实际上，您的SQL语句正在使用：

and finalinsdate >= Feb/18/2013

这不是有效的SQL语句，这意味着PostgreSQL将抱怨：

org.postgresql.util.PSQLException: ERROR: syntax error at or near "Feb"

下次，复制并粘贴源代码，而不是截屏
