JPQL 意外的 AST 节点：大约 "coalesce"

Question

JPQL got an error : threw org.springframework.dao.InvalidDataAccessApiUsageException (org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected AST node: ( near line 3, column 48 ) select invoiceBE from InvoiceBE invoiceBE where invoiceBE.institutionId = ?1 and coalesce(invoiceBE.paidActivity.date < ?2) and invoiceBE.exportedActivity.date < ?3 order by invoiceBE.vendorInvoiceNumber asc

"coalesce"有没有错误？

我运行 sql 好在mysql 数据库中。

select
        *    from
        ACQ_INVOICE invoice 
    where
        invoice.institution_id=91475
        and coalesce(invoice.`user_paid_date` < '2020-01-20', invoice.`paid_date` < '2020-01-20T16:45:40.786Z')

谢谢。

Answer 1

合并表达式看起来完全错误。

我不认为引用属性的反向标记是允许的。这看起来更像是 MySQL SQL 语法。

我也不完全确定 COALESCE 是否可以与布尔表达式一起使用。

Answer 2

改为

合并（发票。user_paid_date，发票。paid_date）<'2020-01-20'

成功了。
