Question

我创建了一个名为Invoice的表，在该表中有两列TotalDue和Total balance。根据我的要求，我检索了数据，如（ SELECT * FROM Invoice_TBL WHERE IsTableStatus = 1 AND ClientNo = 3 AND TotalBalance＆gt; 0 ORDER BY InvoiceNo ASC）上述查询检索了所选客户的所有总余额。

现在我想做的是＆＃34;检索所有总余额，接受一张付费发票没有我选择的余额＆＃34;

或

SELECT AutoInvoiceNo, InvoiceNo, TotalBalance
FROM Invoice_TBL
WHERE IsTableStatus = 1 AND ClientNo = 3 AND TotalBalance > 0 ;


SELECT AutoInvoiceNo, InvoiceNo, TotalBalance
FROM Invoice_TBL
WHERE IsTableStatus = 1 AND ClientNo = 3 AND AutoInvoiceNo = 5

如何合并上述2个查询并获得一个结果..

请帮帮我.. 感谢...

合并where条款：

SELECT AutoInvoiceNo, InvoiceNo, TotalBalance
FROM Invoice_TBL
WHERE IsTableStatus = 1 AND ClientNo = 3 AND (TotalBalance > 0 OR AutoInvoiceNo = 5)

Sql查询在where子句中接受值
