Check out the rolling average for user 123…#WindowFunction What do you think is going on?

Day 29 Today, I learnt how to use a window frame to define the boundaries of the data you want to operate on when using window functions in SQL. #Day29 #30DaysOfSQL #WindowFunction #WindowFrame #Data

i.e. rows with the same value will receive the same rank, and the next rank will be skipped in the RANK function but will not be skipped in the Dense_ Rank function #Day28 #30DaysOfSQL #WindowFunction #RankFunctions #Data

While the LEAD function allows you to access data from a subsequent row within the same result set to compare the current row to a future row. #Day27 #30DaysOfSQL #WindowFunction #AnalyticalFunctions #Lag #Lead #Data

Day 27 Today, I learnt about the Lag and Lead Functions - their similarities and differences The LAG function allows you to access data from a previous row within the same result set to calculate differences or changes over time #Day27 #30DaysOfSQL #WindowFunction #Data

Day 21 Today I learnt how to perform a calculation across a set of table rows and divide the result into partitions, making it possible to perform calculations within each partition using the Over and Partition Clause. #Day21 #30DaysOfSQL #WindowFunction #PartitionClause

Day 20 Today I learnt about window function and how to use it to perform a calculation across a set of table rows using the Over Clause. #Day20 #30DaysOfSQL #WindowFunction #OverClause #Data

Learning #SQL window functions! They allow advanced calculations over a set of table rows. Examples include ROW_NUMBER(), RANK(), DENSE_RANK(), and NTILE(). Great for running totals, moving averages, and ranking data. #DataScience #windowfunction
