推荐答案

从中选择*

TableName t

WHERE CONVERT（Date，t.Fromdate，10）> = CONVERT（Date，@ FromDate，10）

和

CONVERT（日期，t.ToDate，10）< = CONVERT（日期，@ ToDate，10）



如果满足您的需求，请接受此解决方案

Select * from
TableName t
WHERE CONVERT(Date,t.Fromdate,10) >= CONVERT(Date,@FromDate,10)
and
CONVERT(Date,t.ToDate,10) <= CONVERT(Date,@ToDate,10)

Please accept this solution if its fulfill your needs

首先，请勿使用文本框：使用Calendar控件或DateTimePicker。文本框意味着用户输入他们想要的内容，这可能不是有效日期（甚至接近有效日期）。 otehr控件只让他们选择正确的日期，并保存你必须验证它们。



然后，只需使用SQL SELECT：

First off, don't use text boxes: use a Calendar control or a DateTimePicker instead. Textboxes mean that users enter what they want, which may not be a valid date (or even close to a valid date). The otehr controls only let them select "proper" dates, and save you having to validate them.

Then, just use an SQL SELECT:

SELECT * FROM MyTable WHERE MyDateColumn BETWEEN @StartDate AND @EndDate

通过参数化查询填写日期，并直接从控件传递DateTime对象。

Fill in the dates via a parametrised query, and pass the DateTime objects from the controls directly.
