- 1 Count employees, group by CUBE(department no, job title)
- 2 CUBE clause: return rows containing a subtotal for all combinations of columns included in the CUBE clause along with a total
- 3 Cube implies reducing tables by rolling up different columns (dimensions)
- 4 Demonstrate Partial CUBE operation
- 5 group by cube
- 6 group by CUBE(department no, job title)
- 7 Grouping with Cube
- 8 The sequence of the columns passed into Cube function
- 9 Use CUBE and RANK() to get all rankings of sales by product type ID and employee ID
- 10 use GROUPING SETS to produce just a subset of CUBE
Count employees, group by CUBE(department no, job title)
