我有两个实体,即。InvoiceItem 和 ChargeCategory,使用 JPA 语义定义,带有@Column
getter。InvoiceItem#getChargeCategory() 定义如下:
@ManyToOne(optional = false)
@JoinColumn(name = "item_charge_category")
public ChargeCategory getChargeCategory()
{
return chargeCategory;
}
现在,当我尝试使用给定的 item_charge_category 检索所有 InvoiceItems 时,如下所示:
SELECT * FROM InvoiceItem i
WHERE i.chargeCategory.itemChargeCategory = :itemChargeCategory
我收到一个错误
Unexpected token: CROSS in statement
声明如下:
SELECT
<Columns from InvoiceItem>
FROM dist_invoice_items Invoicei0_
CROSS JOIN invoice_charge_types Chargec1_
WHERE Invoicei0_.item_charge_category =
Chargec1_.item_charge_category
AND Chargec1_.item_charge_category = ?
我在用
- 休眠:3.5.5
- HSQLDB:2.0
和persistence.xml是
<persistence-unit name="fssPersistenceUnit" transaction-type="RESOURCE_LOCAL">
</persistence-unit>
有没有人遇到过类似的问题?知道如何纠正这个问题吗?如果有任何进一步的信息有助于解决这个问题,请告诉我。
