I am trying to get a list of users, who submitted a specific event in a website, however when I run the query, I am not getting the full result set - for example, I found 2 users who had the event (and I used the same conditions), but are not in the result set.
The script looks like:
select userid
, Date
from c
where year(c.Date) = 2018
and week(c.Date) = (week(getdate()) - 1)
and Event in ('existing', 'submit_existing', 'submit_new')
group by 1,2
Can anybody give me a hint what might be the issue?
If anything is unclear or if you have any questions, let me know!
Thanks!
https://github.com/dbeaver/dbeaver/issues/1708
Ctrl+Alt+Shift+A or right click menu: Execute => Select all rows.
so I managed to find the answer!
The reason for my problem is that in dbeaver there is a Maximum result-set size filed and if you have a lower number than the result set you are expecting - you will get duplicates and missing data, because each time it runs it shows a new results set.
Hope this can help somebody!

I'm kind new in this forum but I'm stuck in a problem and I need our help.
I Have one table with several lines where each line represent one project, then in another table I'll have many tasks that need to be done in each project, each task would have a percentage of at what level is, and the result of this two tables is one table where I'll have the process Id and also the percentage of accomplished with the average of the last entries of every tasks values.
I can't figured out the query that needs to be done to have the result that I want.
Can anyone help me? You can see follow the link bellow to see tables and the result that I want.
Table iamges
I didnt understand the colors of rows you used, but with your description, i think this is the query you are looking for:
select P.id_Proceso, P.SubProceso, avg(R.estado)
from Processos P
join Registros R
on P.ID = R.Id_processo
group by P.id_Proceso, P.SubProceso
I have a view that lists employee (EmpID), request number (ReqNo), date request was opened (OpenDate) and the date it was moved to the next step in the process (AssignDate). What I am trying to do is get an average of the daily queue size. If EmpID 001 has 20 requests on 1/1/13, then has 24 on 1/2/13, 21 on 1/3/13 the average over 3 days should be 21.66, rounded up to 22. I have the following view:
CREATE VIEW EmpReqs
AS
SELECT [EmpID], [OpenDate], [AssignDate], [ReqID]
FROM [Metrics].[dbo].[Assignments]
WHERE OpenDate BETWEEN '01/01/2013' AND '12/31/2013' AND
[EmpID] IS NOT NULL AND
[ReqNo] NOT LIKE 'M%'
I then wrote a query to pull individual employee's queues per day:
/* First attempt to generate daily queue #s */
SELECT * FROM BLReqs
WHERE [BusLiaison] LIKE 'PN' AND
[OpenDate] <= '11/15/2013' AND
[AssignDate] > '11/15/2013'
Because no one has attempted to pull this information before, I have no way of verifying how accurate the above is. I tried using current dates, since I can see those in our database to compare but the code doesn't work, nothing is returned when I change the dates to 2014 and run my query.
What is the easiest way to verify that my code is correct, short of manually counting a day's queue?
Can anyone see any issues with the above scripts?
Is there a way to get the above code to work with current dates?
This question is really hard to answer because it is kind of broad and has little information at the same time. I'll try anyway:

no way of verifying how accurate the above is.
Try checking the result of this query for a few sampled dates.
I tried using current dates, since I can see those in our database to
compare but the code doesn't work, nothing is returned when I change
the dates to 2014 and run my query.
So clearly, the query is not working. You should probably find out why. Run the query for a date of which you know that it should return results but doesn't. Remove conditions one by one to see which one is incorrectly removing all rows. This should be enough to identify the bug.
Can anyone see any issues with the above scripts?
No, looks fine. A very simple query. That's why I said that we have too little information. There is some key piece of information missing that allows us to find the bug.

Stop staring at the code and hoping for a revelation. Debug it. Experiment.
Hello I need a SQL query statement that gets me rows 'start' to 'finish'.
For example:
A website with many items where page 1 selects only items 1-10, page 2 has 11-20 and so on.
I know how to do this with Microsoft SQL Server and MySQL but I need an implementation that is platform independent. :/
I have an Increment line for IDs but deleting in-between will mess the result when I select via
WHERE ID > number AND ID < othernumber
of course
Is this possible without fetching the whole database to a ResultSet?
I think your safest bet would be to use the BETWEEN operator. I believe it works across Oracle/MySQL/MSSQL.
WHERE ID BETWEEN number AND othernumber
Concerning your comment " I was just think for the case when first 100 IDs are gone I'll have to check further until there is something to fetch", you might wanna consider NOT actually ever deleting stuff from your database but to add a flag like "active" or something like that to your tables so you can avoid situations like the one you're now trying to avoid. The alternative is where you are now, having to find the max and min rows in a filter
I have two tables. Main table is "CompleteEmailListJuly11" and the second table is "CurrentCustomersEmailJuly11". I want to delete rows in CompleteEmailListJuly11 table that CurrentCustomersEmailJuly11 has based off email.
I've tried this following Delete example, but it doesn't do anything close to what I'm trying to do. This only shows me the ones that EXIST in the database, it doesn't show me the the list of emails that AREN'T matching.
DELETE * FROM CompleteEmailListJuly11 AS i
WHERE EXISTS (
SELECT 1 FROM CurrentCustomersEmailJuly11
WHERE CurrentCustomersEmailJuly11.email = i.EmailAddress
)
Help is greatly appreciated.
This is the query I think you need:
DELETE FROM CompleteEmailListJuly11
WHERE EmailAddress IN (SELECT email FROM CurrentCustomersEmailJuly11)
Ps: The DELETE query does not delete individual fields, only entire rows, so the * is not necessary, you will also need to "Execute" this query rather than "Previewing" or "Exporting"
If you're building your DELETE query in Access' query designer, notice there are two different modes of operation which seem similar to "go ahead and do this".
Datasheet View (represented by the grid icon labeled "View" on the "Design" section of the ribbon). That view enables you to preview the affected records, but does not actually delete them.
The "Run" icon (represented by a red exclamation point). "Run" will actually execute the query and delete the affected records.
If you already know this, my description may seem insulting. Sorry. However, it seems that folks new to Access can easily overlook the distinction between them.
You can use something like this adapted to delete
SELECT ... // complete
EXCEPT
SELECT ... // current
I am not sure exactly how it maps to delete but take a look at that.
I fond it in a similar question: How do I 'subtract' sql tables?
We can use Correlated Query to resolve the issue like
DELETE FROM COMPLETE C
WHERE EMAIL = (SELECT EMAIL FROM CURR CU WHERE CU.EMAIL=C.EMAIL);

Here's my problem: I'm working on a social networking app in CF on Wheels, not too dissimilar from the one we're all familiar with in Chris Peters's awesome tutorials. In mine, though, I'm required to display the most recent status message in the user directory. I've got a User model with hasMany("statuses") and a Status model with belongsTo("user"). So here's the code I started with:
users = model("user").findAll(include="userprofile, statuses");
This of course returns one record for every status message in the statuses table. Massive overkill. So next I try:
users = model("user").findAll(include="userprofile, statuses", group="users.id");
Getting closer, but now we're getting the first status record for each user (the lowest status.id), when I want to select for the most recent status. I think in straight SQL I would use a subquery to reorder the statuses first, but that's not available to me in the Wheels ORM. So is there another clean way to achieve this, or will I have to drag a huge query result or object the statuses into my CFML and then filter them out while I loop?
You can grab the most recent status using a calculated property:
// models/User.cfc
function init() {
property(
name="mostRecentStatusMessage",
sql="SELECT message FROM statuses WHERE userid = users.id ORDER BY createdat DESC LIMIT 1,1"
);
}
Of course, the syntax of the SELECT statement will depend on your RDBMS, but that should get you started.
The downside is that you'll need to create a calculated property for each column that you need available in your query.
The other option is to create a method in your model and write custom SQL in <cfquery> tags. That way is perfectly valid as well.
I don't know your exact DB schema, but shouldn't your findAll() look more like something such as this:
statuses = model("status").findAll(include="userprofile(user)", where="userid = users.id");
That should get all statuses from a specific user...or is it that you need it for all users? I'm finding your question a little tricky to work out. What is it you're exactly trying to get returned?
