在JDBC中发送带有unnest（array [someArray]）的三个数组的异常]] << [

Question

我无法将3个数组发送到SQL语句中，它会引发异常

select t.ttt, t.created_date, concat_ws('-',lp.mmm, lp.ccc, lp.eee ) from tasks t
join positions p on t.id = p.task_id
left join lte_position lp on p.id = lp.id
where t.ttt in (:identities) and (lp.mmm, lp.ccc, lp.eee) in
((select mmm,ccc,eee from ((select unnest(array[:mmm]) as mmm, unnest(array[:ccc]) as ccc, unnest(array[:eee]) as eee)) as temp))
order by t.ttt DESC

我想在mmm，ccc，eee中发送3个数组。当我在Postgres控制台上尝试正常运行时，但是当我在Java代码中尝试运行时，会引发异常

org.postgresql.util.PSQLException: ERROR: cannot cast type record to integer
Position: 474

我无法将3个数组发送到SQL语句中，它会从任务t的连接位置选择t.ttt，t.created_date，concat_ws（'-'，lp.mmm，lp.ccc，lp.eee）引发异常p on t.id = p.task_id左连接...

您编写它的方式，PostgreSQL认为您的整个参数字符串都是单个整数。
