我使用了以下查询并获得如下的异常。
java.sql.SQLException:索引:: 2处缺少IN或OUT参数
请帮忙。
select s.ship_id from SHIP S where S.ship_id not in (SELECT ship_id FROM ship WHERE notes1 IS NOT NULL
AND notes1 IN (select notes1 from ship WHERE SHIP_ID <> ? ))
AND S.SHIP_ID = ?
该语句有两个参数引用:
select s.ship_id
from SHIP
where S.ship_id not in (SELECT ship_id
FROM ship
WHERE notes1 IS NOT NULL AND
notes1 IN (select notes1 from ship WHERE SHIP_ID <> ?
)
) and
S.SHIP_ID = ?;
当您执行查询时,您需要提供它们,即使它们 - 可能 - 是相同的。
你似乎是什么船只notes1
领域是独一无二的船。您可以通过其他方式执行此操作:
select s.shipid
from (select s.*,
min(shipid) over (partition by notes1) as mins,
max(shipid) over (partition by notes1) as maxs
from ships s
) s
where mins = maxs and shipid = ?;
