SQL之间不包括所有查询范围（日期）

Question

我有以下结构的表：

我正在尝试在两个日期之间获取分组值，问题是结果不包含日期为2014-09-05的行。

以下是查询：

  SELECT substr(m.date, 1, 10) as my_date, COUNT(m.ID) AS 'NUMBER_OF_ALL_CALLS',
    (SELECT COUNT(*) FROM dialed_calls subq WHERE subq.call_result = 'DONE'
    AND substr(m.date, 1, 10) = substr(subq.DATE, 1, 10)) as 'RESULT_DONE',
    (SELECT COUNT(*) FROM dialed_calls subq WHERE subq.call_result = 'NOT_INTERESTED' 
    AND substr(m.date, 1, 10) = substr(subq.DATE, 1, 10)) as 'RESULT_NOT_INTERESTED',
    (SELECT COUNT(*) FROM dialed_calls subq WHERE subq.call_result = 'NO_APPOINTMENT'
    AND substr(m.date, 1, 10) = substr(subq.DATE, 1, 10)) as 'RESULT_NO_APP'
    FROM dialed_calls m
    WHERE m.date BETWEEN "2014-09-02" AND "2014-09-05"
    GROUP BY my_date

如何解决它以包含给定范围的行。

而且我想问一下，我怎么能为缺少的日子fxp做到这一点：

WHERE m.date BETWEEN "2014-09-02" AND "2014-09-10"

结果返回零值的日期？

非常感谢您的帮助。

表格结构：

BEGIN TRANSACTION;

CREATE TABLE dialed_calls(Id integer PRIMARY KEY,
'date' datetime,
'called_number' VARCHAR(45),
'call_result' VARCHAR(45),
'call_duration' INT,
'synced' BOOL);

/* Create few records in this table */
INSERT INTO dialed_calls VALUES(1,'2014-09-02 15:54:34+0200',
'800123456', 'NOT_INTERESTED', 10, 0);
INSERT INTO dialed_calls VALUES(2,'2014-09-02 15:56:30+0200',
'800123456', 'NO_APPOINTMENT', 10, 0);
INSERT INTO dialed_calls VALUES(3,'2014-09-02 16:01:49+0200',
'800123456', 'DONE', 9, 0);
INSERT INTO dialed_calls VALUES(4,'2014-09-02 16:03:03+0200',
'800123456', 'NO_APPOINTMENT', 69, 0);
INSERT INTO dialed_calls VALUES(5,'2014-09-02 18:09:34+0200',
'800123456', 'NO_APPOINTMENT', 3, 0);
INSERT INTO dialed_calls VALUES(6,'2014-09-02 18:54:02+0200',
'123456789', 'NO_APPOINTMENT', 89, 0);
INSERT INTO dialed_calls VALUES(7,'2014-09-02 18:55:25+0200',
'123456789', 'NOT_INTERESTED', 89, 0);
INSERT INTO dialed_calls VALUES(8,'2014-09-03 18:36:58+0200',
'123456789', 'DONE', 185, 0);
INSERT INTO dialed_calls VALUES(9,'2014-09-04 18:36:58+0200',
'123456789', 'DONE', 185, 0);
INSERT INTO dialed_calls VALUES(10,'2014-09-05 18:36:58+0200',
'123456789', 'DONE', 185, 0);
COMMIT;

Answer 1

如果您只指定日期，则时间默认为00:00:00。如果您将23:59:59添加到结束日期，则应获得完整的日期范围。

Answer 2

x BETWEEN a AND B只是x >= a AND x <= b的缩写。

如果您不希望<=运算符进行第二次比较，请手动将其写出来，然后更改它以便在第二天之前获得任何值：

... WHERE m.date >= '2014-09-02' AND m.date < '2014-09-06'

Answer 3

包含给定范围更改的行

WHERE m.date BETWEEN "2014-09-02" AND "2014-09-05"

的

WHERE substr(m.date, 1, 10) BETWEEN '2014-09-02' AND '2014-09-05'
