将AM PM时间字符串存储到MySQL中的TIME数据类型,并在显示时使用AM PM进行检索？

Question

我在前端输入日期为上午10:00,中午12:00等...(表示12小时格式).现在我想在time databaseatatype 列中保存数据库中的值.如何在AM 中将AM PM值保存为时间数据类型,并再次显示在前端附加AM PM的时间？

要插入:

# replace first argument of STR_TO_DATE with value from PHP/frontend
TIME( STR_TO_DATE( '10:00 PM', '%h:%i %p' ) );

选择:

# replace first argument with your time field
TIME_FORMAT( '22:00:00', '%h:%i %p' );

我将继续并假设你使用mysql lib函数.

// first sanitize the $_POST input
// also, make sure you use quotes to identify the $_POST keys
$open = mysql_real_escape_string( $_POST[ 'MondayOpen' ] );
$close = mysql_real_escape_string( $_POST[ 'MondayClose' ] );

// this is the query, which should work just fine.
$sql = '
    INSERT INTO
        `table_lib_hours`
    SET
        `day_name` = "Monday",
        `day_open_time` = TIME( STR_TO_DATE( "' . $open . '", "%h:%i %p" ) ),
        `day_close_time` = TIME( STR_TO_DATE( "' . $close . '", "%h:%i %p" ) )
    ';

$result = mysql_query( $sql );

然后检索值:

$sql = '
    SELECT
        `day_open_time`,
        `day_close_time`,
        TIME_FORMAT( `day_open_time`, "%h:%i %p" ) as day_open_time_formatted,
        TIME_FORMAT( `day_close_time`, "%h:%i %p" ) as day_close_time_formatted
    FROM
        `table_lib_hours`
    WHERE
        `day_name` = "Monday"
    ';

$resultset = mysql_query( $sql );

这将返回结果集,其中格式化数据位于*_formatted字段中
