Postgresql Reporting Services-连接字符串和参数

这里的正确查询是什么

我想将年份作为一个参数：

select distinct
p.id "pub_id"
from 
publication "p", organisation_association "oa", organisation "o", localized_string_text "lst_org"
where
p.id = oa.publication_id
and oa.organisation_id = o.id
and o.name_id = lst_org.localized_string_id
and p.submission_year = ?
and exists (select 1
        from
        publication "p2", organisation_association "oa2", organisation "o2"
        where
        p2.id = p.id
        and p2.id = oa2.publication_id
        and oa2.organisation_id = o2.id
        and o2.period_end_date < date ? + '-01-01')

---

但是，最后一行的连接会产生语法错误。

如果参数作为年份字符串传递：

and o2.period_end_date < date (? || '-01-01'))

如果是日期：

and o2.period_end_date < date_trunc('year', ?)

如果是年份编号：

and o2.period_end_date < date (?::text || '-01-01'))

谢谢Clodoaldo Neto！！它工作得很好！一次又一次，我被这些论坛的力量压倒了！！
