I followed all the steps in Lab 1, excercise 2 but my answers aren't correct in terms of the number of rows for the sales and international sales tables.
I got 211450 rows for international sales and
10196818 rows for the Sales table.
I've repeated the steps but got the same number of rows.
After combining the CSV files, I removed the first row because it contained unrelated contents(.pydio info), could this have been the cause? Any help will be appreciated, thanks
I've also got the wrong answers. I had 10782612 for International Sales and 9985368 for Sales. No idea how far off wrong I am. I did check the queries and neither had dates for 1999.
I'm having issues as well. My answers came out to be 10782612 for International Sales (none of which the dates were 1999) and 9985368 for Sales (again none of which were from 1999). I'm so confused where my error is.
I got 211,450 rows for International Sales and 10,196,818 rows for Sales which are incorrect answers for Lab1 Exercise 2.
Here are the steps I did from No.4 onwards, red fonts represent the areas that I need the advice. Thanks!
4. Perform the following steps:
5. Edit the Sales Query from the US Sales. (I selected the append queries function on the Sales Query, not sure if this is correct)
6. Append the International Sales table to the Sales query from the US Sales (After appending, I filter the dates after 31/12/1999 on the International Sales Query, not sure if this step is needed?)
7. In the Sales query, add a custom column named Country Name which takes the value of the Country column when it is not null and the value of "USA" when the Country column is null. (No problem)
Hey buddy I had the exact same results as yours. Turns out I didn't filter the Date after appending, so you might want to check again on that. I think this is a commen mistake because it is a bit tricky as Power BI reload the data again including the data from 1999 !
If you go order your 10,826,515 rows in Sales table and 841,147 rows in International Sales you will find some rows with the 1999 date ! If you fix this you should find the correct answer! It fixed the problem for me so I hope it does the same for you. Good luck!
Problem is I did the date filtering. When I did date filtering I had errors. It shows it cannot accept dates like 1/2/2000 etc. So I have to manualay remove dates with 1999.
i have got the same results. i could not filter the date changing the data type of Date column. I did remove as charachter values. because when I tried to filter I got this error message. Then I filtered data just chacking any values less than 31/12/1999
