推荐答案

如何用InvoiceNo，Mobile No检查Ajay?
您应该知道Ajay是客户名称而不是手机号码，发票号码
改变您接受用户输入的方式.使用包含搜索字段CustomerName，InvoiceNo，Mobile No.的下拉列表
首先选择搜索条件，然后在文本框中输入所需的值.
how can you check Ajay with InvoiceNo, Mobile No ?
you should know Ajay is Customer name not Mobile No, invoice No.
change you way of accepting input from user. Use dropdownlist containing search fields CustomerName, InvoiceNo, Mobile No.
first select search criteria and then enter desired value in textbox.
选择invoice.InvoiceNo，invoice.Date，Customer.Name，Customer.MobileNo FROM Customer，发票，其中invoice.CustomerID = Customer. CustomerID和发票.InvoiceNolike''''或Customer.Name如"ajay％"或Customer.MobileNo like''''''
SELECT invoice.InvoiceNo, invoice.Date, Customer.Name,Customer.MobileNo FROM Customer, invoice where invoice.CustomerID=Customer.CustomerID and invoice.InvoiceNo like'''' or Customer.Name like''ajay%'' or Customer.MobileNo like''''
