I need some advice in google query language.
I want to count rows depending on date and a condition. But if the condition is not met, it should return 0.
What I'm trying to achieve:
Date Starts
05.09.2018 0
06.09.2018 3
07.09.2018 0
What I get:
Date Starts
06.09.2018 3
The query looks like =Query(Test!$A2:P; "select P, count(B) where (B contains 'starts') group by P label count(B) 'Starts'")
P contains ascending datevalues and B an event (like start in this case).
How can I force output a 0 for the dates with no entry containing "start"?
The main point is to get all needed data in one table in ascending order. But this is only working, if every day has an entry. If there is no entry for a day, the results for "start" do not match the datevalue in column A. 3 in column D would be in the first row of the table then.
I need it like this:
A B C D
Date Logins Sessions Starts
05.09.2018 1 2 0
06.09.2018 3 4 3
07.09.2018 4 5 0
Maybe this is easy to fix, but I don't see it.
Thanks in advance!
You can do some pre-processing before the query. Ex: check if column B contains 'start' with regexmatch and use a double unary (--) to force the boolean values into 1's and 0's. The use query to sum.
=Query(Arrayformula({--regexmatch(Test!$B2:B; "start")\ Test!$A2:P}); "select Col17, sum(Col1) where Col17 is not null group by Col17 label sum(Col1) 'Starts'")
Change ranges to suit.

Ok so this gets me the count of how many Records of type A are blank in column B
SELECT A, Count(B)
FROM `table1`
where
B = ""
group by A
it gives me a table
A
B
First
564
Second
1985
And that is great. But I want this to summarize by counting blanks in multiple columns, not just blanks in column B, like this:
A
B
C
First
564
9001
Second
1985
223
I have an intuition that this is done by creating another table first that would look like this
A
Column
Value
First
"B"
B value
First
"C"
C value
Second
"B"
B value
Second
"C"
C value
for every document, so you can count blanks, but I'm not sure how to get there. Is this the right approach? or is there a much simpler version using pivot tables or similar?
You could try using a conditional sum,
select A,
Sum(case when b='' then 1 end) B,
Sum(case when c='' then 1 end) C
from t
group by A
I am using influxDB and I would like to extract some values which is greater than certain threshold in other table.
For example, I have two tables as shown in below.
Table A
Time value
1 15
2 25
3 9
4 22
Table B
Time threshold
1 16
2 12
3 13
4 15
Give above two tables, I would like to extract three values which is greater than first row in Table B. Therefore what I want to have is as below.
Time value
2 25
4 22
I tried it using below sql query, but it didn't give any correct result.
select * from data1 where value > (select spec from spec1 limit1);
Look forward to your feedback.
Thanks.
Integrate the condition in an inner join:
select * from tableA as a
inner join tableB as b on a.id=b.id and a.value > b.threshold
When your time column doesn't only include integer values, you have to format the time and join on a time range. Here is an example:
SQL join on time range
i'm looking for a way to, on my query, dynamically set the beginning of the window function on Sql Server using ROWS BETWEEN.
Something like:
SUM(field) OVER(ORDER BY field2 ROWS BETWEEN field3 PRECEDING AND CURRENT ROW)
field3 holds the amount of items (via group by from a CTE) that represent a group.
Is that possible or should i try a different approach?
>> EDIT
My query is too big and messy to share here, but let me try to explain what i need. It's from a report builder which allows users to create custom formulas, like "emplyoees/10". This also allows the user to simply input a formula like "12" and i need to calculate subtotals and the grand total for them. When using a field, like "employees", everything works fine. But for constant values i can't sum the values without rewriting a lot of stuff (which i'm trying to avoid).
So, consider a CTE called "aggregator" and the following query:
SELECT
*,
"employees"/10 as "ten_percent"
12 as "twelve"
FROM aggregator
This query returns this output:
row_type counter company_name department_name employees ten_percent twelve
data 1 A A1 10 1 12
data 1 A A2 15 1,5 12
data 1 A A3 10 1 12
subtotal 3 A 35 3,5 12
data 1 B B1 10 1 12
subtotal 1 B 10 1 12
total 4 45 4,5 12
As you can see, the values fot "twelve" are wrong for subtotal and total row types. I'm trying to solve this without changing the CTE.
ROLLUP won't work because i already have the sum for other columns.
I tried this (i ommited "row_type_sort" on the table above, it defines the sorting):
CASE
WHEN row_type = 'data' THEN
MAX(aggregator.[twelve])
ELSE
SUM(SUM(aggregator.[twelve]))
OVER (ORDER BY "row_type_sort" ROWS BETWEEN unbounded PRECEDING AND CURRENT ROW)
END AS "twelve"
This would work OK if i could change "unbounded" by the value of column "counter", which was my original question.
LAG/LEAD wasn't helpful neither.
I'm out of ideas. Is it possible to achieve what i need only by changing this part of the query, or the result of the CTE should be changed as well?
Thanks
I have a table with 3 columns (sorted by the first two):
letter
number (sorted for each letter)
difference between current number and previous number of the same letter
I'd like to calculate (with vanlla SQL) a fourth new column RESULT to group these data when the third column (difference of number between contiguos record; i.e #2 --> 4 = 5-1) is greater than 30 marking all the records of this interval with letter-number of the first record (i.e A1 for #1,#2,#3).
Since the difference between contiguos numbers makes sense just for records with the same letter, for the first record of a new letter, the value of differnce is 31 (meaning that it's a new group; i.e. #6).
Here is what I'd like to get as result:
# Letter Number Difference RESULT (new column)
1 A 1 1 A1
2 A 5 4 A1
3 A 7 2 A1
4 A 40 33 A40 (*)
5 A 43 3 A40
6 B 1 31 B1 (*)
7 B 25 24 B1
8 B 27 2 B1
9 B 70 43 B70 (*)
10 B 75 5 B70
Now I can only find the "breaking values" (*) with this query where they get a value of 1:
select letter
,number
,cast(difference/30 as int) break
from table
where cast(difference/30 as int) = 1
Even though I'm able to find these breaking values I can't finish my task.
Can anyone help me finding a way to obtain the column RESULT?
Thanks in advance

As I understand you need to construct the last result column. You can use concat to do that:
SELECT letter
,number
,concat(letter, cast(difference/30 as int)) result
FROM table
HAVING result = 'A1'
after some exercise and a little help from a friend of mine, I've found a possible solution to my sql prolblem.
The only requirment for the solution is that my first record must have a value of 31 in Difference field (since I need "breaks" when Difference > 30 than the previous record).
Here is the query to get the column RESULT I needed:
select alls.letter
,alls.number
,ints.letter||ints.number as result
from competition.lag alls
,(select letter
,number
,difference
,result
from (select letter
,number
,difference
,case when difference>30 then 1 else 2 end as result
from competition.lag
) temp
where result = 1
) ints
where ints.letter=alls.letter
and alls.number>=ints.number
and alls.number-30<=ints.number
I have a table whose columns are dynamic, except one column:A. The table also has some null values (0n) in it. How do I add another column that shows total of each row and either ignores the column that has "0n" in that particular row or takes 0 in its place.
Here is my code, it fails on sum and also does not ignore nulls.
addTotalCol:{[]
table:flip`A`B`C`D!4 4#til 9;
colsToSum: string (cols table) except `A; / don't sum A
table: update Total: sum (colsToSum) from table; / type error here. Also check for nulls
:table;
}
I think it is better to use functional update in your case:
addTotalCol:{[]
table:flip`A`B`C`D!4 4#til 9;
colsToSum:cols[table] except `A; / don't sum A
table:![table;();0b;enlist[`Total]!enlist(sum;enlist,colsToSum)];
:table;
}
Reason why it is not working is because your fourth line is parsed as:
table: update Total: sum (enlist"B";enlist"C";enlist"D") from table;
Since sum only works with numbers, it returns 'type error since your inputs are string.
Another solution to use colsToSum as string input:
addTotalCol:{[]
table:flip`A`B`C`D!4 4#til 9;
colsToSum:string cols[table] except `A; / don't sum A
table:get"update Total:sum(",sv[";";colsToSum],") from table"
:table;
}
Basically this will build the query in string before it is executed in q.
Still, functional update is preferred though.
EDIT: Full answer to sum 0n:
addTotalCol:{[]
table:flip`A`B`C`D!4 4#0n,til 9;
colsToSum:cols[table] except `A; / don't sum A
table:![table;();0b;enlist[`Total]!enlist(sum;(^;0;enlist,colsToSum))];
:table;
}
I think there is a cleaner version here without a functional form.
