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，它会运行一段时间。但是，insert语句只插入一次样本数据。在每种情况下，amnountOfFunding总是大于invoiceCharge。期望的结果是对所提取的行进行所有插入。

我有这个循环并插入我需要的每条记录！也许你可以修改或更新你的循环！

MySQL：Procedure循环，但只插入一次
