我希望这个查询能够自动地知道今天的日期和时间以及一年(或一个月)(或一周)的第一天......
SELECT TicketID
FROM Ticket
WHERE (Ticket.DtCheckOut > '1/1/2011 12:00:00 AM')
AND (Ticket.DtCheckOut < '8/27/2011 12:00:00 AM')

我知道它会GETDATE()以某种形式使用,但你不想看到我想出的东西,我保证!
这是我在MDSN上阅读的GETDATE() 内容:GETDATE(Transact-SQL)
我环顾四周和谷歌 - 并没有找到任何'干净' - 所以任何输入都会很棒!
我有一个这样的程序:
mysql> call Ticket_FiscalTotals(100307);
+---------+--------+----------+------------+------------+
| Service | Items | SalesTax | eTaxAmount | GrandTotal |
+---------+--------+----------+------------+------------+
| 75.00 | 325.00 | 25.19 | 8.00 | 433.19 |
+---------+--------+----------+------------+------------+

我想在select中调用这个过程,如下所示:
SELECT Ticket.TicketID as `Ticket`,
Ticket.DtCheckOut as `Checkout Date / Time`,
CONCAT(Customer.FirstName, ' ', Customer.LastName) as `Full Name`,
Customer.PrimaryPhone as `Phone`,
(CALL Ticket_FiscalTotals(Ticket.TicketID)).Service as `Service`
FROM Ticket
INNER JOIN Customer ON Ticket.CustomerID = Customer.CustomerID
ORDER BY Ticket.SiteHomeLocation, Ticket.TicketID

但是我知道这是非常错误的.有人可以指点我正确的方向吗?我需要在最终的Select中访问程序中的所有列(加入?).该过程中的SQL代码相当痛苦,因此首先是它的原因!
我有一个基本的WinForms应用程序与d DataGridView(名为dgvHardware)控件,绑定到此控件是这段代码:
private void dgvHardware_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
if (e.Control is ComboBox)
{
((ComboBox)e.Control).SelectionChangeCommitted -= new EventHandler(cboDgvHardware_SelectionChanged);
((ComboBox)e.Control).SelectionChangeCommitted += new EventHandler(cboDgvHardware_SelectionChanged);
}
}
private void cboDgvHardware_SelectionChanged(object sender, EventArgs e)
{
// string result is the selected text of the combo box
// int row is the row index that the selected combo box lives
string result = ((ComboBox)sender).SelectedItem.ToString();
// int row = ????
}

简而言之,我需要能够确定事件被触发的行,以便根据ComboBox选择更改行中的其他单元格.第二个函数的结果返回正确的值,这是值得的.
如果不清楚或者您是否需要任何其他信息,请告诉我.
谢谢,
