Question

我正在使用PHP + MSSQL的博客Web应用程序。

博客表...

Pk_blog_id

//整数PK

Blog_title

//字符串

Blog_content

//文字

Created_at

// DateTime

我想用几个月从表中收集数据。

我的查询是。

$first_day= date('Y-m-01', $month);   // Getting First day of Month
$last_day = date('Y-m-t', $month);   // Getting Last Day of Month

$sql = "SELECT 
    Pk_blog_id,
    Blog_title,
    Blog_content,
    Created_at 
    FROM dbo.tb_IEAG_Blogs 
    WHERE Is_archived = 0 
    AND Created_at >= CONVERT(datetime,'$first_day') 
    AND Created_at < CONVERT(datetime,'$last_day') 
    ORDER BY tb_IEAG_Blogs.Pk_blog_id DESC";

我没有按预期得到结果......

当回显查询时如下...

SELECT 
 Pk_blog_id,
 Blog_title,
 Blog_content,
 Created_at 
 FROM dbo.tb_IEAG_Blogs 
 WHERE Is_archived = 0 
 AND Created_at >= CONVERT(datetime,'2016-02-01') 
 AND Created_at < CONVERT(datetime,'2016-02-28') 
 ORDER BY tb_IEAG_Blogs.Pk_blog_id DESC

这可能是MSSQL中的BETWEEN吗？

...谢谢

LoginPath = new PathString("/Login/"),

试试这个。由于您要比较日期时间，因此2016-02-01日期时间不等于表中的日期时间。

如果你想选择月份，这里有一个更好的SQL。

SELECT 
 Pk_blog_id,
 Blog_title,
 Blog_content,
 Created_at 
 FROM dbo.tb_IEAG_Blogs 
 WHERE Is_archived = 0 
 AND cast(Created_at as date) >= '2016-02-01'
 AND cast(Created_at as date) <'2016-02-28'
 ORDER BY tb_IEAG_Blogs.Pk_blog_id DESC

MSSQL datetime字段没有获取结果
