Can someone help me sort a date dimension in a QlikView pivot? The dimension is set as follows:
Week(DateField) & chr(13) & '' & Weekstart(DateField,0,-1)
An example of value:
"43
10/19/2014"
Another example:
"1
12/28/2014"
chr(13) returns a new line so that the week number and the day with which the week starts are placed on two different rows.
I have tried putting this expression in a listbox to play with it and to try different variants for sorting. Below are my attempts:
Sort by expression: =DateField
Sort by expression: =LEFT(DAY(DateField) + NUM(MONTH(DateField))*100 + YEAR(DateField)*10000,100)
Sort by expression: =LEFT(DateField,2) (not ok anyway as it would not work if multiple years were loaded)
etc
but nothing seems to work
Any help is much appreciated.
Like you said, the issue is that when you create that concatenation, it becomes a string and it's sorted as such.
Luckly, QlikView has the Dual function that can help you in this case, defining the dimension as a calculated dimension with the following expression :
=Dual(Week(DateField) & chr(13) & '' & Weekstart(DateField,0,-1), Weekstart(DateField,0,-1))
The syntax of Dual is Dual(Text, Numeric Value), meaning that it will create an object that will be represented by the value Text but sorted by the Numeric Value.
Check QlikView help page for this function for further information.
This should work:
=Weekstart(DataField,0,-1)

I have a field set that contains bill numbers and I want to sort them first alphabetically then numerically.
For instance I have a column "Bills" that has the following sequence of bills.
- HB200
- SB60
- HB67
Desired outcome is below
- HB67
- HB200
- SB60
How can I use sorting in SSRS Group Properties to have the field sort from [A-Z] & [1 - 1000....]
This should be doable by adding just 2 separate Sort options in the group properties. To test this, I created a simple dataset using your examples.
CREATE TABLE #temp (Bills VARCHAR(20))
INSERT INTO #temp(Bills)
VALUES ('HB200'),('SB60'),('HB67')
SELECT * FROM #temp
Next, I added a matrix with a single row and a single column for my Bills field with a row group.
In the group properties, my sorting options are set up like this:
So to get this working, my theory was that you needed to isolate the numeric characters from the non-numeric characters and use each in their own sort option. To do this, I used the relatively unknown Regex Replace function in SSRS.
This expression gets only the non-numeric characters and is used in the top sorting option:
=System.Text.RegularExpressions.Regex.Replace(Fields!Bills.Value, "[0-9]", "")
While this expression isolates the numeric characters:
=System.Text.RegularExpressions.Regex.Replace(Fields!Bills.Value, "[^0-9]", "")
With these sorting options, my results match what you expect to happen.
In the sort expression for your tablix/table which is displaying the dataset, set the sort to something like:
=IIF(Fields!Bills.Value = "HB67", 1, IIF(Fields!Bills.Value = "HB200", 2, IIF(Fields!Bills.Value = "SB600", 3, 4)))
Then when you sort A-Z, it'll sort by the number given to it in the sort expression.
This is only a solution if you don't have hundreds of values, as this can become quite tedious to create if there's hundreds of possible conditions.
I have a query to the Cognitive text keyphase API from Microsoft from '16 Excel Power Query - getting keywords from tweets. Works fine.
However, the JSON doc that's returned per query is converted by Power Query into a list of ~1-5 rows.
In the case of the pic, I want all responses returned to be in one cell/row, regardless of the number of items returned.
Here is my full M query (you need to put your own key in) if you're interested.
let
TweetCognitive = (TweetID as text, TweetText as text) =>
let
JsonRecords = Text.FromBinary(Json.FromValue([id=TweetID, text=TweetText])),
JsonRequest = "{""documents"": [" & JsonRecords & "]}",
JsonContent = Text.ToBinary(JsonRequest, TextEncoding.Ascii),
Response =
Web.Contents("https://westus.api.cognitive.microsoft.com/text/analytics/v2.0/keyPhrases?",
[
Headers = [#"Ocp-Apim-Subscription-Key"="yourkeyhere",
#"Content-Type"="application/json", Accept="application/json"],
Content=JsonContent
]),
JsonResponse = Json.Document(Response,1252)
in
JsonResponse
in
TweetCognitive
You can use List.Accumulate to turn a list of values into a single value. For example, this would combine the values in the list into a single text value with ". " separating each row's value:
List.Accumulate(JsonResponse, "", (state, current) => state & current & ". ")
This would generate "monday frank love happiness today. nice good kind. tomorrow. " in your example. If you want to get rid of the trailing space, you can surround the List.Accumulate expression with Text.Trim.
The basic function to concatenate elements in a list is Text.Combine. For instance:
Text.Combine(JsonResponse, " ")
This avoids the extra delimeter at the end you get with List.Accumulate. Note also List.Combine is for creating a longer combined list from shorter lists, and the similar naming there may cause confusion.
I have a grid on a form that displays some columns from a dbf table and a textbox.
I want to search the value displayed in the textbox over all columns from a dbf table. Some fields are numeric and other are character
If I want to find a number, should search all record that contain that number in all columns, no matter the column type.
If I want to search a substring should give me all record that contain that substring.
SET FILTER TO ALLTRIM(ThisForm.Text1.Value) $Content or ALLTRIM(val(ThisForm.Text1.Value)) $registrationNumber or ALLTRIM(ThisForm.Text1.Value) $holderNo
Your approach with the "$" wildcard "contains" approach appears to be ok. However, your attempt via allt( val( )) would fail as you cant trim a numeric value, it would have to be pre-converted to a string.
Now, that said, you could shorten your query by just doing a $ against a concatenation of ALL columns something like (assuming your registration number is a numeric field)...
set filter to ALLTRIM(ThisForm.Text1.Value) ;
$ ( Content +"," +str(registrationNumber) +," + holderNo )
if you have dates or date/time fields you could do DTOC( dateField ) or TTOC( dateTimeField). So, by building a single string of all values, you dont have to explicitly repeat the OR condition repeatedly.
You could do something like:
select curGrid
scan
lcRow = transform(field1) + transform(field2) ... + transform(lastfield)
if lcSearchValue $ lcRow
DoWhatever()
endif
endscan
This leverages the fact that transform() will give a string representation of any data type.
I want to fetch substring from string in column between last '/' and last '.' .
Here is sample date for IMAGE_PATH column name:

sph/images/9_Pennethorne_House.jpeg
rbkc/images/TAVISTOCK_CRESCENT.jpeg

wandle/images/f13c10d2-2692-457d-a208-8bb9e10b27dc.png
So the required output is like
30_Fairhall_Court
9_Pennethorne_House
TAVISTOCK_CRESCENT
399932thumb
18190862
f13c10d2-2692-457d-a208-8bb9e10b27dc
No14_Asterid Heights_DS37620
f13c10d2-2692-457d-a208-8bb9e10b27dc
Please suggest how to fetch. I need to update another blank column in table with this value. The table has around 10 lacks records.
One of possible solutions is to use functions substr() and instr() with negative third parameter:
select image_path,
substr(image_path,
instr(image_path, '/', -1) + 1,
instr(image_path, '.', -1)-instr(image_path, '/', -1) - 1) img
from test
SQL Fiddle
Results:
IMAGE_PATH IMG

This regex works with the sample data you provided:
select regexp_substr(image_path
, '(/)([a-z0-9_ \-]+)(\.)([a-z]+)$'
, 1
, 1
, 'i'
, 2)
from t23
/
We have to include all the optional parameters after pattern so we can use the subexpr parameter to select just the filename element. Find out more.
As far as the updating goes, a million row table isn't that big. Given that you have to update all the rows there's not much you can do to tune it. Just issue the UPDATE statement and let it rip.
"its not working"
Hmmm, here's a SQL Fiddle which proves it does work. You've probably introduced a typo.
"The regexp looks unnecessary complex. Why not simply"
Perhaps it is too complicated. However your simplified version doesn't produce the correct result if there's more than one dot in the IMAGE_PATH. If that's never going to happen then your solution works just fine.
Excuse me, occasionally I refer with some problem that maybe it's already been fixed. In any case, I would appreciate a clarification on vs.
I have a TariffeEstere table with the fields country, Min, Max, tariff
from which to extract the rate for the country concerned, depending on whether the value is between a minimum and a maximum and I should return a single record from which to extract its tariff:
The query is:
stsql = "Select * from QPagEstContanti Where country = ' Spain '
and min <= ImpAss and max >= ImpAss"
Where ImpAss is a variable of type double.
When I do
rstariffa.open ststql,.....
the recodset contains a record if e.g. ImpAss = 160 (i.e. an integer without decimals), and then the query works, but if it contains 21,77 ImpAss (Italian format) does not work anymore and gives me a syntax error.
To verify the contents of the query string (stsql) in fact I find:
Select * from QPagEstContanti Where country = 'Spain' and min < = 21,77 and max > = 21,77
in practice the bothering and would like a comma decimal, but do not know how do.
I tried to pass even a
format (ImpAss, "####0.00"),
but the value you found in a stsql is 21,77 always.
How can I fix the problem??
It sounds like the underlying language setting in SQL is expecting '.' decimals instead of ',' decimal notation.
To check this out - run the DBCC useroptions command and see what the 'language' value is set to. If the language is set to English or another '.' decimal notation - it explains why your SQL string is failing with values of double.
If that's the problem, the simplest way to fix it is to insert the following line after your stsql = statement:
stsql = REPLACE(stsql, ",", ".")
Another way to fix it would be to change the DEFAULT_LANGUAGE for the login using the ALTER LOGIN command (but this changes the setting permanently)
Another way to fix it would be to add this command to the beginning of your stsql, which should change the language for the duration of the rs.Open:
"SET LANGUAGE Italian;"
