我有一个PostgreSQL函数：
func(timestamp,timestamp,Integer[],varchar[])
我想设计一个JasperReports报告来从函数中获取数据。为此，我创建了 list 类型的参数以从用户那里获取输入并将其作为varchar数组传递。
为此，我正在尝试使用以下查询：
select * from func($P{interval_start}::timestamp,$P{interval_end}::timestamp,array[$P!{idParameter}],array[$P!{usersParameter}])
但是当我运行报告时，它会给出类似column user1(passed from parameter) does not exist.
我也试过：
select * from func($P{interval_start}::timestamp,$P{interval_end}::timestamp,array[$P!{idParameter}],array[$P{usersParameter}])
但它说：
Compiling to file... /home/Prashant/Desktop/jasper-report/report2.jasper

请建议，如何将字符串数组从iReport传递给PostgreSQL函数？
