In my project we are consuming the company's data via Web Service REST. Today we don't do the query dynamically by passing the start date and end date parameters via string.
enter image description here
My goal is for the end date to update dynamically. I've already created a query that takes the current date but I can't put it in the parameter without generating an error in the query.
enter image description here
This is the error message I get when I put the column value in the parameter:

I'm pretty sure I'm getting the syntax wrong. Anyone who can help me, I really appreciate it. I would like to point out that the date format for the API call to work is DD/MM/YYYY.
Can you try using
PutYourOtherTableNameHere[Hoje_Coluna]{0}
instead of
[Hoje_Coluna]
?
To see if that will work, put this in right before your query, then click on the step and see what it returns.
x = PutYourOtherTableNameHere[Hoje_Coluna]{0},

Please excuse my lack of knowledge in explaining my problem as i have only just started learning Power Bi.
I am attempting to return data by using a dynamic variable within my source url.
Source = Json.Document(Web.Contents("https://api.****.com/jobs/{ID}/invoices", [Headers=[Authorization="Bearer "&GetToken()]]))
I have successfully returned the data i needed from multiple queries Blank Query 1 Query Names
However, i am trying to run a final query in which a job ID needs to be specified.
Source = Json.Document(Web.Contents("https://api.****.com/jobs/{ID}/invoices", [Headers=[Authorization="Bearer "&GetToken()]]))
With the bold item being the variable.
I have successfully returned values by hard coding the variable (seen below).
Hard coded variable
However, i would like to make dynamic in that it will return the values for all the Job ID's witin the "jobs" table.
Job Id's
I don't know if what im asking is possible, or if my explanation is good enough, but any help would be greatly appreciated!
What you are looking for is a custom function.
Make a function out of your above query by adding (ID) => in the first line and separating "ID" in your URL string.
(ID) =>
let
Source = Json.Document(Web.Contents("https://api.****.com/jobs/{" & ID & "}/invoices", [Headers=[Authorization="Bearer "&GetToken()]]))
in
Source
Of cause you can add all your other transformation steps too.
Now take your JobIDs table and add a column by invoking a custom function, select the above function and take the ID parameter from your ID column.
For every row you'll get a separate table and all that's left is simply expanding these tables into your query.
This will solve your problem.
I've created a function from a query that fetches the weather forecast from darksy.net API.
Basically, I pass the latitude and longitude as a single parameter to the query and I get a weather forecat.
The parameter is entered as text in the form of "lat,long". Eg: Lisbon is 38.736946,-9.142685
Everything works fine, the data is loaded into Power Query. However, when hitting "Close and Apply" button I get the error:
It seems the URL is adding E2%80%8E before the parameter.
I tried 2 differente APIs (darksy.net and http://api.openweathermap.org) and the problem happens in both.
Why is this? Can anyone help?
I am trying to save data into my table using an interactive grid with the help of custom plsql. I am running into an "ORA-01403-no data found" error while inserting data and I can't figure out why.
This is my plsql custom process which I run. Appreciate your help.
DECLARE
em_id NUMBER;
BEGIN
CASE :apex$row_status
WHEN 'C'
THEN
SELECT NVL (MAX (emergency_id), 0) + 1
INTO em_id
FROM emp_emergency_contact;
INSERT INTO emp_emergency_contact
(emergency_id, emp_id, emergency_name, emergency_relation
)
VALUES (em_id, :emp_id, :emergency_name, :emergency_relation
);
WHEN 'U'
THEN
UPDATE emp_emergency_contact
SET emergency_name = :emergency_name,
emergency_relation = :emergency_relation
WHERE emergency_id = :emergency_id;
WHEN 'D'
THEN
DELETE emp_emergency_contact
WHERE emergency_id = :emergency_id;
END CASE;
END;
So far I have not come across any documented way on how to use custom PL/SQL logic for processing submitted rows of APEX 5.1 Interactive Grid via AJAX call.
You are getting no data found error because the return is expected to be in certain json format.
The example you have provided is not too complex and can be with done using standard "Interactive Grid - Automatic Row Processing (DML)" process, which is an AJAX approach. If AJAX call is not important then you can create your own PL/SQL process with custom logic. Example of which is demonstrated in "Sample Interactive Grids" package application, check out Advanced > Custom Server Processing page in this application for more information.
I agree with Scott, you should be using a sequence or identity column for ids.
Not entirely sure. A 'select into' can raise a no_data_found exception, but yours shouldn't.
That being said, you shouldn't have max(id)+1 anywhere in your code. This is a bug. Use a sequence or identity column instead.
I have gotten this many times so the first thing I do is go look at any columns in my grid sql that are not part of the "Save", they are from a join for data only.
I just got it again and it was a heading sort column that I had as a column type of "Number". I changed it to display only and the "Save" now works.
Although, I had already set the "Source" of the column to "Query Only" which is also needed.
It is a bummer the Ajax error message doesn't at least give the column name that caused the error.
Hope this helps someone..

Add a RETURNING INTO clause after the insert. IG expects a primary key to be returned to query the inserted row.
For example:
The given sample HP Flights SampleAppData.xls and using the CreateFlightOrder, we can link the data to the test functions and get a OrderNumber and Price response from the Web Service. And in the SampleAppData.xls Input tab, we can see that there is a empty column of OrderNumber.
So here is my question, is there any ways that I can take the OrderNumber response and fill the empty column in SampleAppData.xls?
My point to do this is because, let's say I have many test cases to do and will take days, and today I do this certain test and I would need the result of today for the next day's test.
Although I know that the responses are saved in the result but it beats the point of automation if I am required to check the response for each and every test cases?
Yes of course you can. There are a number of ways to do this. The simplest is as follows.
'Datatable.Value("columnName","sheetName")="Value"
DataTable.Value(“Result”,”Action1”)=“Pass”
Once you have recorded the results in the Datasheet, your can export them using
DataTable.ExportSheet("C:\SavePath\Results.xls")
You can write back the response programatically , if you already imported mannually .
You can use GetDataSource Class of UFT API , it will work like this lets say you imported excel from FlightSampleData.xls, and named it as FlightSampleData, you have sheet, accessing the sheet will be like below:
GetDataSource("FlightSampleData!input).Set(ROW,ColumnName,yourValue);
GetDataSource("FlightSampleData!input).Get(ROW,ColumnName);
for exporting you can use ExportToExcelFile method of GetDataSourse class after your test run . Please let me know if you have any furthur question about this.
I am writing simple SELECT queries which involve parsing out date from a string.
The dates are typed in by users manually in a web application and are recorded as string in database.
I am having CASE statement to handle various date formats and use correct format specifier accordingly in TO_DATE function.
However, sometimes, users enter something that's not a valid date(e.g. 13-31-2013) by mistake and then the entire query fails. Is there any way to handle such rougue records and replace them with some default date in query so that the entire query does not fail due to single invalid date record?
I have already tried regular expressions but they are not quite reliable when it comes to handling leap years and 30/31 days in months AFAIK.
I don't have privileges to store procedures or anything like that. Its just plain simple SELECT query executed from my application.
This is a client task..
The DB will give you an error for an invalid date (the DB does not have a "TO_DATE_AND_FIX_IF_NOT_CORRECT" function).
If you've got this error- it means you already tried to cast something to an invalid date.
I recommend doing the migration to date on your application server, and in the case of exception from your code - send a default date to the DB.
Also, that way you send to the DB an object of type DbDate and not a string.
That way you achieve two goals:
1. The dates will always be what you want them to be (from the client).
2. You close the door for SQL Injection attacks.
It sounds like in your case you should write the function I mentioned...
it should look something like that:
Create or replace function TO_DATE_SPECIAL(in_date in varchar2) return DATE is
ret_val date;
begin
ret_val := to_date(in_date,'MM-DD-YYYY');
return ret_val;
exception
when others then
return to_date('01-01-2000','MM-DD-YYYY');
end;
within the query - instead of using "to_date" use the new function.
that way instead of failing - it will give you back a default date.
-> There is not IsDate function .. so you'll have to create an object for it...
I hope you've got the idea and how to use it, if not - let me know.
I ended up using crazy regex that checks leap years, 30/31 days as well.
Here it is:
((^(0?[13578]|1[02])[\/.-]?(0?[1-9]|[12][0-9]|3[01])[\/.-]?(18|19|20){0,1}[0-9]{2}$)|(^(0?[469]|11)[\/.-]?(0?[1-9]|[12][0-9]|30)[\/.-]?(18|19|20){0,1}[0-9]{2}$)|(^([0]?2)[\/.-]?(0?[1-9]|1[0-9]|2[0-8])[\/.-]?(18|19|20){0,1}[0-9]{2}$)|(^([0]?2)[\/.-]?29[\/.-]?(((18|19|20){0,1}(04|08|[2468][048]|[13579][26]))|2000|00)$))
It is modified version of the answer by McKay here.
Not the most efficient but it works. I'll wait to see if I get a better alternative.
