Answer 1

我会选择第一个示例输出：

select Date, sum(case when intent = 'default' then 1 else 0 end) 
from table t
group by Date;

Answer 2

这有帮助吗？

    Create Table #tmp([Date] Date,ID int, intent Varchar(10))

    Insert into #tmp
    SELECT '9/1/2018',1,'fetch it' Union All
    SELECT '9/1/2018',1,'Ask it' Union All
    SELECT '9/1/2018',1,'default' Union All
    SELECT '9/1/2018',2,'remand' Union All
    SELECT '9/1/2018',2,'choose it' Union All
    SELECT '9/2/2018',1,'fetch it' Union All
    SELECT '9/2/2018',1,'choose' Union All
    SELECT '9/2/2018',1,'default' Union All
    SELECT '9/3/2018',4,'Ask it' Union All
    SELECT '9/3/2018',4,'fetch it' Union All
    SELECT '9/4/2018',5,'hello' Union All
    SELECT '9/4/2018',1,'call' Union All
    SELECT '9/4/2018',1,'default' Union All
    SELECT '9/5/2018',1,'remand'Union All
    SELECT '9/5/2018',1,'default' Union All
    SELECT '9/5/2018',2,'fetch it' Union All
    SELECT '9/5/2018',2,'default' 


    ;with cte
    As
    (
        Select *,LEAD(intent) over(partition by [Date] order by (Select null)) as FollowingIntent
        from #tmp   
    )

    Select Date, SUM(CASE WHEN FollowingIntent='default' then 1 else 0 end)
    from cte
    Group by [Date]

    Drop Table #tmp

    DECLARE @Sample TABLE
    (
        theDate DATE NOT NULL,
        ID INT NOT NULL,
        Intent VARCHAR(20) NOT NULL
    );

INSERT  @Sample
VALUES  ('20180901', 1, 'fetch it'),
    ('20180901', 1, 'Ask it'),
    ('20180901', 1, 'default'),
    ('20180901', 2, 'remand'),
    ('20180901', 2, 'choose it'),
    ('20180902', 1, 'fetch it'),
    ('20180902', 1, 'choose'),
    ('20180902', 1, 'default'),
    ('20180903', 4, 'Ask it'),
    ('20180903', 4, 'fetch it'),
    ('20180904', 5, 'hello'),
    ('20180904', 1, 'call'),
    ('20180904', 1, 'default'),
    ('20180905', 1, 'remand'),
    ('20180905', 1, 'default'),
    ('20180905', 2, 'fetch it'),
    ('20180905', 2, 'default');
