錯誤信息「功能名稱丟失」。「在視覺foxpro 9.0

Question

我無法將SQL語句轉換爲FoxPro。我遇到的麻煩是我得到了錯誤代碼「Function name is missing）」，但我無法弄清楚問題出在哪裏或哪裏。麻煩在下面一行。任何幫助是極大的讚賞。

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

整個foxpro的代碼如下。

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 

我轉換的SQL代碼位於下方，最初是從存儲過程中捕獲的。

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,

Answer 1

我會翻譯這：

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

就象這樣：

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

編輯：

如何：

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

對不起，這是行不通的。這是主要的一個單獨的選擇陳述。

編輯2：

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

可以嘗試簡化它，只是爲了解決：

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

我道歉，在黑暗中刺傷。
