hibernate联合主键，使用insert select插入数据报错

语句如下：
INSERT INTO CasFinanceData (id.asCode,id.financeUpdateDate,asName) SELECT a.id.asCode,a.id.financeUpdateDate,a.asName FROM CasFinanceDataTemp a where a.id not in (SELECT id from CasFinanceData)
其中：CasFinanceData表结构与CasFinanceDataTemp一致，CasFinanceDataTemp作为临时表辅助进行数据导入操作。asCode、financeUpdateDate为联合主键。
报错信息如下：
