Question

这是我的查询完美运行

"SELECT RemBal FROM Sales WHERE CustomerName='" & CustomerName.Text & "'"

现在我正在尝试以两个基础客户名称和＆amp;当前日期

"SELECT RemBal FROM Sales WHERE CustomerName='" & CustomerName.Text & "' AND SaleDate=#" & SaleDate.Value & "#"

现在这个查询没有给我任何错误，但也没有返回任何值请帮忙

Answer 1

试试这个

SaleDate.Format = DateTimePickerFormat.Custom
SaleDate.CustomFormat = "yyyy-mm-dd"

"SELECT RemBal FROM Sales WHERE CustomerName='" & CustomerName.Text & "' AND SaleDate=#" & SaleDate.Text()  &"# "

Answer 2

SELECT rembal 
FROM   sales 
WHERE  customername = '" & CustomerName.Text & "' 
       AND Format(saledate, 'dd/MM/yyyy') = '" & SaleDate.Value & "'

SQL查询日期相关的SELECT语句
