我有一个简单的查询,需要使用“开始和结束日期”变量来提取过去10天(直到昨天的11:59,直到当前日期)为止的过去10天雇用的所有员工。
我知道有许多设置此日期范围的方法。 能为您提供过去10天(不包括当前日期)的开始和结束日期的最有效的SQL Server表达式是什么?
DECLARE @StartDate = ???
DECLARE @EndDate = ???
SELECT @StartDate, @EndDate
所需结果:
2020-04-02 00:00:00.000, 2020-04-11 23:59:59.000
答案 0 :(得分:3)
:59方案不是一个好主意。比较应小于第二天(的开始),以便包括前一天的整个时间。
private static void AddToStockLoop(int itemid, int itemquantity, double itemprice)
{
if (itemid <= 0)
{
Console.WriteLine("Item ID Cannot Be Less Than 1, Please Try Again");
itemid = ReadInteger("Item ID:");
AddToStockLoop(itemid, itemquantity, itemprice); //Recursive call now with a new value of the paramter itemid
}
if (itemquantity <= 0)
{
Console.WriteLine("Quantity Cannot Be Less Than 1, Please Try Again");
itemquantity = ReadInteger("Quantity:");
AddToStockLoop(itemid, itemquantity, itemprice); //Recursive call now with a new value of the paramter itemquantity
}
if (itemprice < 0.01)
{
Console.WriteLine("Item Price Cannot Be Less Than 0, Please Try Again");
itemprice = ReadDouble("Item Price:");
AddToStockLoop(itemid, itemquantity, itemprice); //Recursive call now with a new value of the paramter itemprice
}
}
但是,如果您仍然想要它:
SELECT @StartDate = DATEADD(dd,-10,CAST(getdate() AS DATE)), @EndDate = CAST(getdate() AS DATE)
答案 1 :(得分:0)
希望此代码对您的情况适用:
connect(mBulbWindow, &MBulbWindow::transferEntity, this, &MainWindow::addEntity)
