Question

我有一个问题如何在MySQL查询中为日期范围添加查询。日期仅生成。

这是我的查询：

SELECT TS.id AS TSid, employeeid, `date` AS date_d, TS.TI1 AS TI1, TS.TO1 AS TO1,
                            CONCAT(E.lastName,', ',E.firstName,' ',E.middleInitial,'.') AS 'fullname',

                            (TIME_TO_SEC(CAST(TS.`TI1` AS time))/3600) AS 'timeinint',                  
                            (TIME_TO_SEC(CAST(TS.`TO1` AS time))/3600) AS 'timeoutint',
                            E.startDate, C.companyName, B.branchName,
                            R.mon, R.tue, R.wed, R.thu, R.fri, R.sat, R.sun
                    FROM timeschedule AS TS
                    LEFT JOIN  employee AS E ON TS.employeeid = E.id
                    LEFT JOIN  company AS C ON E.companyid = C.id
                    LEFT JOIN  branch AS B ON E.branchid = B.id
                    LEFT JOIN restday AS R ON R.id = E.restDayid
                    WHERE TS.`show` = '1'  
                    ORDER BY employeeid ASC

我是如何获得输入的：

$mfrom = $this->input->get('mfroma');  //From: Month
$yfrom = $this->input->get('yfroma');  //From: Year
$yto = $this->input->get('ytoa');      //To : Year

Answer 1

使用您指定的字段（从月份，年份到年份），您可以将这些条件添加到WHERE子句中。我将在此示例中使用E.startDate字段：

$sql = "-- your query here...
    WHERE
        TS.`show` = '1'
        AND MONTH(E.startDate) >= " . $mfrom . "
        AND YEAR(E.startDate) BETWEEN " . $yfrom . " AND " . $yto . "
    ORDER BY employeeid ASC";

<强>文件： - MONTH() - YEAR()

注意： PHP解析双引号内的变量，但我个人更喜欢将PHP变量保留在它们之外。

如何在当前的MySQL查询中添加日期范围查询？
