Query on timeuuid type does not return correct results via cql


Query on timeuuid type does not return correct results via cql

I wish this help you In order to use a timeuuid column like this, you would need to make it a clustering column rather than a partition key (docs). You would need to adapt this to fit your data model, but here's an example:
code :
create table sample (
  id int,
  tid timeuuid,
  category text,
  title text,
  primary key (id, tid)
);
insert into sample (id, tid) values (100, now());
insert into sample (id, tid) values (100, now());
insert into sample (id, tid) values (100, now());
insert into sample (id, tid) values (100, now());
select id,tid,dateOf(tid) from sample;

 id  | tid                                  | dateOf(tid)
-----+--------------------------------------+--------------------------
 100 | df4387a0-8fa8-11e4-bd3a-97fb52c7ef8c | 2014-12-29 14:20:19-0800
 100 | e085a490-8fa8-11e4-bd3a-97fb52c7ef8c | 2014-12-29 14:20:21-0800
 100 | e2bd6c20-8fa8-11e4-bd3a-97fb52c7ef8c | 2014-12-29 14:20:24-0800
 100 | e475f190-8fa8-11e4-bd3a-97fb52c7ef8c | 2014-12-29 14:20:27-0800
select id,tid,dateOf(tid) from sample where id=100 and tid>=minTimeuuid('2014-12-29 14:20:24-0800');

 id  | tid                                  | dateOf(tid)
-----+--------------------------------------+--------------------------
 100 | e2bd6c20-8fa8-11e4-bd3a-97fb52c7ef8c | 2014-12-29 14:20:24-0800
 100 | e475f190-8fa8-11e4-bd3a-97fb52c7ef8c | 2014-12-29 14:20:27-0800
select id,tid,dateOf(tid) from sample where tid>=minTimeuuid('2014-12-29 14:20:24-0800');

like below fixes the issue You are very close - just use some aggregation (GROUP BY) and the MAX function to get what you want, like so:
code :
select a.accountid
from account as a
inner join contact as c
on a.accountid = c.accountid
group by a.accountid
having MAX(isnull(c.Field1, '')) = ''

will help you The .raw fields are setup by logstash as "not_analyzed" fields in elasticsearch. As such, they are not split into tokens and can be used intact.
To elasticsearch, entityId really looks like ['12345', '67n'], which is why your query doesn't match.

seems to work fine Seeing the values '2', 'user', 'admin', etc., you probably confused the columns value and type. Moreover when mixing AND and OR make sure you get your parentheses straight.
Apart from that use explicit joins rather than the long out-dated comma-separated join syntax, don't use quotes on numbers and use IN instead of several ORs on the same field.
code :
SELECT 
  r.sequence, r.status, r.title, r.duedate, 
  r.related_customer, r.added_by 
FROM reminders r
JOIN reminders_users ru ON r.sequence = ru.reminder_seq 
WHERE r.sequence > 0
AND
(
  (ru.value = 'user' AND ru.type = 2) 
  OR 
  ru.value IN ('admin', 'technical_support', 'sales', 'accounts')
)  
ORDER BY field(status, '', 'Completed'), duedate ASC;

Any of those help You only need one SELECT, use case expressions to do conditional counting:
code :
SELECT COUNT(case when CaseHearings.IsClosingDate = 1 then 1 end) TotalCases,
       COUNT(case when CaseHearings.IsClosingDate = 0 then 1 end) TotalPedningCases,
       Districts.DistrictName
FROM Cases
INNER JOIN ConcernedOffices ON ConcernedOffices.pk_ConcernedOffices_ID = Cases.fk_ConcernedOffices_Cases_ConcernedOfficeID
INNER JOIN Districts ON Districts.pk_Districts_DistrictID = ConcernedOffices.fk_Districts_ConcernedOffices_DistrictID
INNER JOIN CaseHearings ON CaseHearings.fk_Cases_CaseHearings_CaseID = Cases.pk_Cases_CaseID
GROUP BY Districts.DistrictName
What type of join do I need to use in the below sql query to retrieve the correct results?

This might help you I want to return the appropriate information about a user from three different tables in my database using SQL joins and a group concat function. Which joins are appropriate for what I am trying to achieve? , Just add one more outer join & do aggregation :
code :
SELECT users.username, users.user_firstname, users.user_lastname,
       users.user_role,
       GROUP_CONCAT(Events.Event_Name) AS Event_Names,
       COUNT(Events.Event_Name) AS Event_count
FROM users LEFT JOIN 
     user_events 
     ON users.id = user_events.id LEFT JOIN
     Events 
     ON Events.id = user_events.event_id
GROUP BY users.username, users.user_firstname, users.user_lastname, users.user_role;
