Question

我尝试在Hibernate 4.3.6 / 4.3.7

中使用下面的insert语句执行批量插入

INSERT INTO TransAttrDO (
    custCode,
    partNo,
    custAttrType,
    qtyUnit,
    createServer
)

SELECT 
    DISTINCT pp.vendorCode,
    pp.partNo,
    'PT',
    pp.qtyUnit,
   'myhost'
FROM PalletPartInfoDO pp
WHERE pp.orderNo = 'SI-HKG-00000001'

我在下面得到了例外。

15:41:22,542 ERROR ErrorCounter:78 - <AST>:8:32: unexpected AST node: DISTINCT

当我删除DISTINCT关键字时，它会成功插入记录。如果我执行带有DISTINCT而没有插入的select语句，它可以正常工作。

有人可以帮忙吗？

使用DISTINCT为INSERT语句（Hibernate HQL）抛出异常
