Please make more videos like this
Hi Sir, if there is a set of different Excel files and there are steps applied to them, like merge, combine and group, and there is an update in one/many Excel files in terms of values and it is not possible to update each and every column value, in this case how can we replace the Excel file/files (keeping the same file name) so that the all the steps can/will be applied as it is after file replacement
Really it is a great video. Very valuable info. Thanks bro
Glad you liked it
Rate of speech is very fast in between if we wish to understand words run away... It's my opinion
May I ask you to please change the speed under TH-cam video settings
thanks alot💯
Sir upload video real time senario base questions in power bi
Please check all the videos of this series. I have uploaded all.
Why filters are better option than slicers though they are static?
Because of performance. Also, there are some functionality differences like advanced options in filter pane
Hi there .. i didn't get the point ..* Ensure reports and data sources are in the same region ? ... What does it mean ..
If you have reports and data sources in the same region than there will be very low latency. For example, you are working in India but your Data Source lies in US Region, than it would take a lot of time to load report compared to if you have your data source somewhere in India.
That's why we should alway try to keep Data Source and Reports in the same region.
I hope this will answer your question.
@@BIConsultingPro Thank you .. very helpful
Good stuff
Hello sir
How to Implement RLS in DQ mode or mixed storage mode.
How to answer this question in interview
As per my study it cannot be implemented in DQ mode
Yes, it's a limitation with Power BI. However, there are some alternate ways to do it. I'll create a video on this topic. For the time being, please read here: radacad.com/row-level-security-on-a-directquery-to-power-bi-dataset-composite-model-my-findings
Failed to save modifications to the server. Error returned: 'The following system error occurred: Class not registered
'. I got this error while loading data, what can I do?
Please installed Power Bi Desktop version after downloading from Website NoT from App Store.
Also, may I ask you to at least try find answers using google search before asking? This way, you’ll learn and you won’t need any body’s help
@@BIConsultingPro Thank you for helping me out
Hi bro. I faced one interview quen can you please give me answer for this.. i have dept table in that i need to find dept wise 3 rd highest salary if 3 rd highest salary not there then need to print 2 nd highest salary if 2 nd also not then need to print 1 St highest salary
Hi there,
You need to create a measure to solve this problem as follows:
Step 1: Distinct Count = DISTINCTCOUNT('dept'[Salary])
Step 2: 3rd Highest Salary =
VAR RankLimit = IF([Distinct Count] >= 3, 3, IF([Distinct Count] >= 2, 2, 1))
RETURN
CALCULATE(MAX('dept'[Salary]),
FILTER(ALL('dept'), 'dept'[Dept] = EARLIER('dept'[Dept]) && RANKX(ALL('dept'[Salary]), 'dept'[Salary], , DESC) = RankLimit))
@@BIConsultingPro hi. In SQL I want to write query
See 1 have 3 dept (it,admin, sales) in it dept 3 records are there in that i want to get 3 rd highest salary. In admin dept I have 2 records are there so here need to pick 2 nd highest salary. In sales dept I have only one record there need to get that salary (means 1st highest salary)
@@padduslifestyle you can try this:
SELECT dept_name,
CASE
WHEN COUNT(DISTINCT salary) >= 3 THEN
(SELECT MAX(salary) FROM dept d2
WHERE d1.dept_name = d2.dept_name
AND salary NOT IN
(SELECT MAX(salary) FROM dept d3
WHERE d1.dept_name = d3.dept_name
OR d3.salary = (SELECT MAX(salary) FROM dept d4
WHERE d1.dept_name = d4.dept_name
AND d3.salary = d4.salary)
)
)
WHEN COUNT(DISTINCT salary) = 2 THEN
(SELECT MAX(salary) FROM dept d2
WHERE d1.dept_name = d2.dept_name
AND salary != (SELECT MAX(salary) FROM dept d3
WHERE d1.dept_name = d3.dept_name))
ELSE
MAX(salary)
END AS '3rd_Highest_Salary'
FROM dept d1
GROUP BY dept_name
@@padduslifestyle select * from department order by salary Desc limit 2,1;
