请问怎么筛选这种条件的数据。
select b.LoanBackBlank,a.ContractNm,SUM(a.RepayAmount)-SUM(a.receivableAmount) repaymoney,b.CustomNm,b.LoanBkAccount,b.LoanBkBank,b.LoanBkBankID,b.CustomType,b.LoanBackBlank
from InterestReceive a,OPSInf b where a.ContractNm=b.LoanNm
group by b.LoanBackBlank,a.ContractNm,b.CustomNm,b.LoanBkAccount,b.LoanBkBank,b.LoanBkBankID,b.CustomType

SQL提取出来的数据，是包含repaymoney=0的数据，怎么才能让他大于等于0.01的数据才筛选出来。

[解决办法]
select b.LoanBackBlank,a.ContractNm,SUM(a.RepayAmount)-SUM(a.receivableAmount) repaymoney,b.CustomNm,b.LoanBkAccount,b.LoanBkBank,b.LoanBkBankID,b.CustomType,b.LoanBackBlank
from InterestReceive a,OPSInf b where a.ContractNm=b.LoanNm
group by b.LoanBackBlank,a.ContractNm,b.CustomNm,b.LoanBkAccount,b.LoanBkBank,b.LoanBkBankID,b.CustomType
having SUM(a.RepayAmount)-SUM(a.receivableAmount)>=0.01
[解决办法]

SQL code

having SUM(a.RepayAmount)-SUM(a.receivableAmount)>=0.01
