Tidy data is… “a standardized way to link the structure of a dataset (its physical layout) with its semantics (its meaning)”. If we ignore the GROUP BY for one moment, the value of the 4 columns will be either the value in the RESULTS column if the Quarter is equal to the Quarter in the CASE expression or it will be NULL if it doesn't match. I prefer to refer to tidy data as “indexed”, and wide data as “Cartesian” (this terminology is from the ggplot2 text) because these terms help me understand what is happening when the data get transformed.     PIVOT( SUM(SalesAmount) Specify a column the values of which will be rows. For example, a fan could use filtering to count the number of matches against a particular opponent, or sort the date column to figure what Lomachenko’s late fight. Next: Database Design. Email here.

Re: Pivot Table Rows into Columns stored procedure. Some RDBMS like oracle has special function for this operation.Unfortunately To create a spreadsheet like the one above, we can use the tidyr::pivot_wider() function. In that case, you can write a dynamic query to first grab all the unique values for the pivot column at runtime and then a write dynamic query to execute it with the pivot query as shown below: UNPIVOT is another relational operator in SQL Server that performs almost the reverse operation of PIVOT, by rotating column values into rows values. Therefore, these steps should be followed again: (1) use group by to reduce the rows to one row per entity, (2) use filter or case to pick the right attribute for each column. UNPIVOT carries out almost the reverse operation of PIVOT, by rotating columns into rows.Suppose the table produced in the previous example is stored in the database as pvt, and you want to rotate the column identifiers Emp1, Emp2, Emp3, Emp4, and Emp5 into row values that correspond to a particular vendor. In this article, we will learn how can we pivot rows to columns in the Hive.
