MySQL：程序循环，但只能插入一次

Question

CREATE DEFINER=`root`@`localhost` PROCEDURE `GenerateCharges2`() 
BEGIN 
Declare sumFunding LONG; 
Declare done INT DEFAULT FALSE; 
Declare invoiceCharge LONG; 
Declare agencyID INT; 
declare invoiceID int; 
Declare fundingID INT; 
Declare amountOfFunding LONG; 
Declare getInvoiceData CURSOR For select invoices.idInvoices, invoices.idAgencies, invoices.InvoiceAmount, fundings.FundingBalance, fundings.idfundings from invoices 
inner join agencies on invoices.idAgencies = agencies.idAgencies 
inner join fundings on agencies.idAgencies = fundings.IdAgencies 
where processed =0 
group by invoices.idInvoices; 
DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = TRUE; 


open getInvoicedata; 
ze_loop: Loop 
Fetch getInvoiceData into invoiceID, agencyID, invoiceCharge, amountOfFunding, fundingID; 
if done then leave ze_loop; 
end if; 
if amountOfFunding > invoiceCharge then 
insert into charges VALUES (invoiceCharge, invoiceID, fundingID); 
end if; 
end loop; 
close getInvoiceData; 
END 

我的问题是，如果你要插入一个select语句，它会运行一个适当的时间。但是，插入语句仅对示例数据插入一次。在任何情况下，amnountOfFunding总是比invoiceCharge大。期望的结果是所有插入都发生在获取的行上。

我有这个循环，并插入我需要的每个记录！也许你可以修改或更新你的循环！
