I have 2 columns in my google sheet - Time, and some Ids
My aim is to calculate the number of ids reported in an hour. For example, from this image we can tell from 10AM to 11AM - 4 ids, and from 11AM to 12PM - 5 ids. I want to come up with a QUERY Function ONLY that helps me do so, and group the number of IDs hour-wise. Any help would be much appreciated.
use:
=QUERY(QUERY(A2:B,
"select hour(A),count(B) where B is not null group by hour(A)"),
"offset 1", )
Use this
=ArrayFormula({"Hour","Id's";UNIQUE(HOUR(A1:A18)),COUNTIF(IF(B:B="",,HOUR(A:A)),"="&UNIQUE(HOUR(A1:A18))&"")})
Using Lambda
You need to set the range refrence once, like this example A:B.
=ArrayFormula(
LAMBDA(r, LAMBDA(t,i,
{"Hour","Id's";UNIQUE(t),COUNTIF(t,"="&UNIQUE(t))})
(HOUR(INDEX(r,,1)),INDEX(r,,2)))
(QUERY({A:B}," where Col1 is not null ")))
Explanatoin
What we did is Query where Col1 non empty in the first lambda call and
in the second lambda we name col1 t for time with the call HOUR(INDEX(r,,1))
and col1 i for id's with the call INDEX(r,,2)
and we use the two columns in COUNTIF that can be simplified like this.
COUNTIF(t,"="&UNIQUE(t))
Now we join UNIQUE(t) and COUNTIF in an Array {}
{"Hour","Id's";UNIQUE(t),COUNTIF(t,"="&UNIQUE(t))}

i'm having trouble creating a query that'll group together responses from multiple rows that share a similar name and count the specific response record in them.
the datatable i currently have looks like this
test_control
values
test
selected
control
selected
test us
not selected
control us
selected
test mom
not selected
control mom
selected
what i'd like, is an output like the below that only counts the number of "selected" responses and groups together the rows that have either "control" or "test" in the name"
test_control
values
test
3
control
1
The query i have below is wrong as it doesn't give me an output of anything. The group by section is where im lost as i'm not sure how to do this. tried to google but couldn't seem to find anything. appreciate any help in advance!!!
SELECT distinct(test_control), values FROM `total_union`
where test_control="%test%" and values="selected"
group by test_control, values
use below
SELECT
REGEXP_EXTRACT(test_control, r'^(TEST|CONTROL) ') AS test_control,
COUNTIF(values = 'selected') AS values
FROM `total_union`
GROUP BY 1
As mentioned by #Mikhail Berlyant, you can use REGEX_EXTRACT to match the expression and COUNTIF to get the count of the total number of matching expressions according to the given condition. Try below code to get the expected output :
Code
SELECT
REGEXP_EXTRACT(test_control, r'^(test|control)') AS test_control,
COUNTIF(values = "selected") AS values
FROM `project.dataset.testvalues`
group by 1
Output
Can I select a column based on another column's value being listed as a formula? So I have a table, something like:
column_name formula val
one NULL 1
two NULL 2
three one + two NULL
And I want to do
SELECT
column_name,
CASE WHEN formula IS NULL
val
ELSE
(Here's where I'm confused - How do I evaluate the formula?)
END as result
FROM
table
And end up with a result set like
column_name result
one 1
two 2
three 3
You keep saying column, and column name, but you're actually talking about rows, not columns.
The problem is that you (potentially) want different formulas for each row. For example, row 4 might be (two - one) = 1 or even (three + one) = 4, where you'd have to calculate row three before you could do row 4. This means that a simple select query that parses the formulas is going to be very hard to do, and it would have to be able to handle each type of formula, and even then if the formulas reference other formulas that only makes it harder.
If you have to be able to handle functions like (two + one) * five = 15 and two + one * five = 7, then you'd be basically re-implementing a full blown eval function. You might be better to return the SQL table to another language that has eval functions built in, or you could use something like SQL Eval.net if it has to be in SQL.
Either way, though, you've still got to change "two + one" to "2 + 1" before you can do the eval with it. Because these values are in other rows, you can't see those values in the row you're looking at. To get the value for "one" you have to do something like
Select val from table where column_name = 'one'
And even then if the val is null, that means it hasn't been calculated yet, and you have to come back and try again later.
If I had to do something like this, I would create a temporary table, and load the basic table into it. Then, I'd iterate over the rows with null values, trying to replace column names with the literal values. I'd run the eval over any formulas that had no symbols anymore, setting the val for those rows. If there were still rows with no val (ie they were waiting for another row to be done first), I'd go back and iterate again. At the end, you should have a val for every row, at which point it is a simple query to get your results.
Possible solution would be like this kind....but since you mentioned very few things so this works on your above condition, not sure for anything else.
GO
SELECT
t1.column_name,
CASE WHEN t1.formula IS NULL
t1.val
ELSE
(select sum(t2.val) from table as t2 where t2.formula is not null)
END as result
FROM
table as t1
GO
If this is not working feel free to discuss it further.
I'm looking for SQL query that will give me a simple percentage value based upon the number of occurrences of a value in a table with a single data column.
Example:
Table has single column of data, which has a header and 10 data rows:
COLUMN_HEADER
XYZ://abc123xyz456-0
XYZ://abc123xyz456-1
XYZ://abc123xyz456-2
XYZ://abc123xyz456-3
ABC://abc123xyz456-4
XYZ://abc123xyz456-5
XYZ://abc123xyz456-6
ABC://abc123xyz456-7
XYZ://abc123xyz456-8
XYZ://abc123xyz456-9
I'm looking for the query to look for all data that does not start with XYZ://*
and give that as a % of the row count.
In the above example, there are two rows that start with ABC:// and eight that start XYZ:// therefore the result should be:
80.00%
(so 8 out of 10 rows do not start with XYZ://)
As you can tell by now I'm a noob in SQL.
MS SQL 2014
Thanks in advance.
You can do this with conditional aggregation:
select avg(case when COLUMN_HEADER like 'XYZ://%' then 1.0 else 0 end) as xyz_ratio
Your logic and examples are backwards. 80% of the rows have values that do start with "XYZ://". Use like or not like as appropriate.
I am trying to run a query that calculate with a countif function but I am having trouble with it. I have used the count and the iif functions in the builder but I think something weird is going on. I am trying to count the number of times a certain value occurs in a column so I do not want a specific value to equal to if that's possible?
Thanks!
To count the number of times a value appears you can use something like.
If you want to know how many times each value appears just omit the WHERE clause (without a sample of data I've used a table in the database I'm working on).
SELECT ProcessID,
COUNT(ProcessID)
FROM tbl_PrimaryData_Step1
WHERE ProcessID = 4
GROUP BY ProcessID
if you need just the value you can use:
SELECT COUNT(ProcessID)
FROM tbl_PrimaryData_Step1
WHERE ProcessID = 4
GROUP BY ProcessID
Another way is:
SELECT DCOUNT("ProcessID","tbl_PrimaryData_Step1","ProcessID = 4")
Edit:
In reply to your comment on your original post this SQL will give the result you're after:
SELECT Concatenate,
COUNT(Concatenate)
FROM MyTable
GROUP BY Concatenate
My ssrs has three row groups nested, and in one of the rows the report runs many times.
I'd like to add something simple to the rows, such as "%" at the end, but only on the first row returned, not the rest of the dynamic rows. My idea was to use:
=RowNumber("detailsGroup") but all that returns is one for each row. Is there another SSRS method?
I was also thinking of using the "is" operator and comparing the dynamic values to the First operator, but running the report gave #ERROR.
If you are using groups you should be able to use Previous() function.
EXample:
Group 1 - ClientName
Group 2 - Region
Group 3 - SubRegion
Detail - data for above 3 groups
If I just want to add something in one of the detail data then I would use ..
=Fields!CallReason.Value + IIF(Previous(Fields!ClientName.Value) <> Fields!ClientName.Value , " Add Text For First Line", "")
