Question

我在将SQL语句转换为FoxPro时遇到问题。我遇到的麻烦是我得到错误代码“函数名称丢失了。”，但我无法弄清楚问题是什么或在哪里。问题出在下面。非常感谢任何帮助。

NVL(select sum(amount) from tpaymentitem where tpaymentitem.invoiceid = 0 and tpaymentitem.programid = (select max(tinvoiceitem.programid) FROM tinvoiceitem),0) as prepay,;

整个foxpro代码如下。

Select  acc.accountid,;
ti.invoiceid,;
ti.invoicedate,;
DATE() - ti.invoicedate as invage,;
sum(NVL([subtotalregular],0) + NVL([fedtaxregular],0) + NVL([statetaxregular],0) + NVL([localtaxregular],0)) as invamount, ;
NVL((select sum(amount) from tpaymentitem where invoiceid = ti.invoiceid),0) as paidamt,;
(sum(NVL([subtotalregular],0) + NVL([fedtaxregular],0) + NVL([statetaxregular],0) + NVL([localtaxregular],0)) - NVL((select sum(amount) from tpaymentitem where invoiceid = ti.invoiceid),0)) as invbalance,;
max(tii.programid) as programid,;
NVL(select sum(amount) from tpaymentitem where tpaymentitem.invoiceid = 0 and tpaymentitem.programid = (select max(tinvoiceitem.programid) FROM tinvoiceitem),0) as prepay,;
do while com.stchargeinterest = 1 AND acc.nofincharge = 0 ;
  if DATE() - ti.invoicedate >= com.stmindaysforinterest ;
    ROUND((sum(NVL([subtotalregular],0) + NVL([fedtaxregular],0) + NVL([statetaxregular],0) + NVL([localtaxregular],0)) - NVL((select sum(amount) from tpaymentitem where invoiceid = ti.invoiceid),0)) * ((com.stinterestrate / 365) * DATE() - ti.invoicedate)),2);
  ENDif  ;
ENDdo as financecharge,;
com.stchargeinterest,;
com.stinterestrate,;
acc.nofincharge,;
com.stmindaysforinterest,;
com.stinterval;
INTO cursor tmpbalance;
FROM taccount acc;
INNER JOIN tcompany com ON com.companyid=acc.companyid;
LEFT JOIN tinvoice ti ON ti.accountid=acc.accountid;
LEFT JOIN tinvoiceitem tii ON ti.invoiceid=tii.invoiceid;
WHERE acc.accountid = m.cust_no AND acc.companyid = 1;
GROUP BY acc.accountid,ti.invoiceid,ti.invoicedate,com.stinterval,com.stchargeinterest ,;
com.stinterestrate,acc.nofincharge,com.stmindaysforinterest,acc.companyid

我正在转换的SQL代码位于下方，最初是从存储过程中捕获的。

Select  acc.accountid,ti.invoiceid,ti.invoicedate,DateDiff(d,ti.invoicedate,getdate()) as invage,
sum(isnull([subtotalregular],0)+isnull([fedtaxregular],0)+isnull([statetaxregular],0)
    +isnull([localtaxregular],0)) as invamount, 
ISNULL((select sum(amount) from tpaymentitem where invoiceid=ti.invoiceid),0) as paidamt,
(sum(isnull([subtotalregular],0)+isnull([fedtaxregular],0)+isnull([statetaxregular],0)
    +isnull([localtaxregular],0)) -
ISNULL((select sum(amount) from tpaymentitem where invoiceid=ti.invoiceid),0)) as invbalance,
max(tii.programid) as programid,
ISNULL((select sum(amount) from tpaymentitem where invoiceid=0 and programid = max(tii.programid)),0) as prepay,
CASE WHEN (com.stchargeinterest = 1) AND (acc.nofincharge=0) THEN
    CASE WHEN DateDiff(d,ti.invoicedate,getdate()) >= com.stmindaysforinterest THEN
        ROUND((sum(isnull([subtotalregular],0)+isnull([fedtaxregular],0)+isnull([statetaxregular],0)+isnull([localtaxregular],0)) 
            -ISNULL((select sum(amount) from tpaymentitem where invoiceid=ti.invoiceid),0)) 
            * ((com.stinterestrate / 365) * DateDiff(d,ti.invoicedate,getdate())),2)
    ELSE  0 END 
ELSE 0 END as financecharge,com.stchargeinterest ,com.stinterestrate,
acc.nofincharge,com.stmindaysforinterest,com.stinterval
INTO #tmpbalance
FROM taccount acc
INNER JOIN tcompany com ON com.companyid=acc.companyid
LEFT JOIN tinvoice ti ON ti.accountid=acc.accountid
LEFT JOIN tinvoiceitem tii ON ti.invoiceid=tii.invoiceid
WHERE acc.accountid= @accountid AND acc.companyid = @companyid
GROUP BY acc.accountid,ti.invoiceid,ti.invoicedate,com.stinterval,com.stchargeinterest ,

我会翻译这个：

ISNULL((select sum(amount) from tpaymentitem where invoiceid=0 and programid = max(tii.programid)),0) as prepay

这样：

NVL( (select sum(amount) from tpaymentitem where invoiceid=0 and programid = max(tii.programid)) ,0) as prepay

编辑：

这个怎么样：

( sum(NVL(amount,0)) from tpaymentitem where invoiceid=0 and programid = max(tii.programid) ) as prepay

抱歉，这不会奏效。它是与主要声明分开的选择声明。

编辑2：

(select sum(NVL(amount,0)) from tpaymentitem where invoiceid=0 and programid = max(tii.programid)) as prepay

可以尝试简化它，只是为了排除故障：

(select sum(amount) from tpaymentitem where 1) as prepay

我为在黑暗中刺伤而道歉。
