mysql - 查询表达式中的语法错误(缺少运算符) sri.invoiceNo = sri.invoiceNo INNER JOIN Staff s oN s.Staffid = sr.userld

Question

"SELECT SalesReturnId, ReturnDate, sr.InvoiceNo, (lastname & ', ' & firstname & ', ' &  MI) as StaffName, TotalAmount, SUM(sri.Quantity) as TotalQuantity FROM SalesReturn sr INNER JOIN SalesReturnItem sri ON sr.InvoiceNo = sri.InvoiceNo INNER JOIN Staff s ON s.StaffId = sr.userID WHERE ReturnDate  BETWEEN '" + startDate.ToString("yyyy-MM-dd") + "' AND '" + endDate.ToString("yyyy-MM-dd") + "' AND sr.InvoiceNo LIKE '%" + txtName.Text + "%' GROUP BY sr.InvoiceNo ORDER BY ReturnDate, sr.InvoiceNo DESC";

当我运行该查询时，我不断收到此错误:

syntax error (missing operator) in query expression sri.invoiceNo = sri.invoiceNo INNER JOIN Staff s oN s.Staffid = sr.userld

Answer 1

在 Access 中，当您有多个联接时需要括号:

SELECT SalesReturnId, ReturnDate, sr.InvoiceNo, 
(lastname & ', ' & firstname & ', ' &  MI) as StaffName,
TotalAmount, SUM(sri.Quantity) as TotalQuantity 
FROM (SalesReturn sr 
INNER JOIN SalesReturnItem sri ON sr.InvoiceNo = sri.InvoiceNo )
INNER JOIN Staff s ON s.StaffId = sr.userID 
WHERE ReturnDate  BETWEEN '" + startDate.ToString("yyyy-MM-dd") + "' AND '" + endDate.ToString("yyyy-MM-dd") + "' 
AND sr.InvoiceNo LIKE '%" + txtName.Text + "%' 
GROUP BY sr.InvoiceNo 
ORDER BY ReturnDate, sr.InvoiceNo DESC;
