这是我的选择陈述
SelectQuery<Record> selectQueryPayment = transaction.selectQuery();
selectQueryPayment.addSelect(AccountPayment.ACCOUNT_PAYMENT.PAYMENT_NUMBER,AccountPayment.ACCOUNT_PAYMENT.PAYMENT_AMOUNT,AccountPayment.ACCOUNT_PAYMENT.PAYMENT_TYPE,
AccountPayment.ACCOUNT_PAYMENT.PAYMENT_DATE,AccountPayment.ACCOUNT_PAYMENT.PAYMENT_AMOUNT,AccountPayment.ACCOUNT_PAYMENT.PAYMENT_AMOUNT.subtract(AccountPayment.ACCOUNT_PAYMENT.AMOUNT_REFUNDED.add(AccountPayment.ACCOUNT_PAYMENT.AMOUNT_APPLIED)));
在这里,您可以看到带有一些计算的复杂选择
ACCOUNT_PAYMENT.PAYMENT_AMOUNT.subtract(AccountPayment.ACCOUNT_PAYMENT.AMOUNT_REFUNDED.add(AccountPayment.ACCOUNT_PAYMENT.AMOUNT_APPLIED))
如何为此创建别名?然后从中获取数据?
答案 0 :(得分:1)
好的,我得到了我们可以使用的解决方案
AccountPayment.ACCOUNT_PAYMENT.PAYMENT_AMOUNT.subtract(AccountPayment.ACCOUNT_PAYMENT.AMOUNT_REFUNDED.add(AccountPayment.ACCOUNT_PAYMENT.AMOUNT_APPLIED)).as("OverPayment")
我们必须添加as("Alias Name")
并获取值,我们必须使用
Result<Record> resultPayment = selectQueryPayment.fetch();
for(Record record : resultPayment){
feeAmount = resultPayment.getValues("OverPayment");
}
