如何选择NOT IN值（Formula Crystal报表）

Question

我在SQL Server中有以下查询：

select * from  ARInvoices ar 
left join ARInvoiceDetails det on ar.InvoiceID = det.InvoiceID
where ar.InvoiceID not in (select InvoiceID from CashReceiptInvoices ) 
and det.SubmitTo = 1 and VoucherStatus = 0 and det.TransactionType = 1

我想通过Crystal Reports XI中的公式来使用它，但是我很难在不使用它的情况下使用。我使用<>，但结果却是空的。

Answer 1

您可以使用“ anti-join”（带有约束的LEFT JOIN ，其中要加入表的IS NULL ）来消除NOT IN ：

select * from  ARInvoices ar 
left join ARInvoiceDetails det on ar.InvoiceID = det.InvoiceID
left join CashReceiptInvoices cri on ar.InvoiceID = cri.InvoiceID -- new JOIN
where cri.InvoiceID is null                                       -- no match
and det.SubmitTo = 1 and VoucherStatus = 0 and det.TransactionType = 1

Answer 2

我不知道水晶报表在所有，但如果这只是NOT IN您遇到麻烦，但你的LEFT JOIN工作正常，那么你可以只添加一个LEFT JOIN ：

select * 
from  ARInvoices ar 
left join ARInvoiceDetails det on ar.InvoiceID = det.InvoiceID
left join CashReceiptInvoices cri on ar.InvoiceID = cri.InvoiceID
where  cri.InvoiceID IS NULL
   and det.SubmitTo = 1 
   and VoucherStatus = 0 
   and det.TransactionType = 1
