if i have multiple sum columns how should I perform

[@Lord_JABA]

How to do the same unpivot but with multiple columns so for example if I have not only "company" but "company","category","randomCol" want them to be unchanged. so result is
columns :company, category, randomcol, quarter, revenue
same effect as DAX(powerbi): Table.Unpivot(#"step1", {"Q1","Q2"}, "Quarter", "Revenue")- which adds columns quarter and revenue leaving all the other columns present in the table multiplicated when needed

Hi Raja, Thanks for this effort to make our self to boost pyspark knowledge. Can I know How to access all those code in the pyspark playlist?

[@purnimasharma9734]

Hi Raja, If you have more than 30 columns, is there a way to get the values dynamically (rather than typing each column's name and values) when you unpivot the data?

[@rajasdataengineering7585]

Hi Purnima, yes it is possible with python logic. Though I haven't done, it's certainly possible

How to perform multiple Unpivot operations?

[@sravanthireddy3849]

Hi Raja,
what about the interview do they ask syntax for functions ?? please reply

[@rajasdataengineering7585]

Hi Sravanthi, ideally interviewers are looking for the thought process of a candidate. So no exact syntax is expected

How to perform unpivot in spark SQL?

[@rajasdataengineering7585]

select col1, stack(3, 'col2', col2, 'col3', col3, 'col4', col4) as (column,agg_value) from table

[@ranaumershamshad]

Videos are very informative, but the starting and ending music is so annoying.

[@rajasdataengineering7585]

Changed the starting music in later videos
