The sort criteria can be expressions, including column names, user-defined functions, arithmetic operations, or CASE expressions. The expressions are evaluated and the results are used for the sorting, i.e., the values stored in the column or the results of the function call. ORDER BY is the only way to sort the
Coercing all values into strings, as in the EAV data example above, results in a simple, but non-scalable, structure: constant data type inter-conversions are required if one wants to do anything with the values, and an index on the value column of an EAV table is essentially useless.
Column labels are used to apply a filter to one or more columns that have to be shown in the pivot table. For instance if the "Salesperson" field is dragged to this area, then the table constructed will have values from the column "Sales Person", i.e., one will have a number of columns equal to the number of "Salesperson". There will also be ...
An index normally includes a "key" or direct link to the original row of data from which it was copied, to allow the complete row to be retrieved efficiently. Some databases extend the power of indexing by letting developers create indexes on column values that have been transformed by functions or expressions.
To use column-major order in a row-major environment, or vice versa, for whatever reason, one workaround is to assign non-conventional roles to the indexes (using the first index for the column and the second index for the row), and another is to bypass language syntax by explicitly computing positions in a one-dimensional array.
Another resident, Edvard Jensen, was more dismissive, telling DR that he didn’t believe Trump would invade Greenland. “He just wants the attention, and now he has it.”
More specifically, it’s a diet “that focuses on foods with high volumes of water and fiber, i.e. fruits, non-starchy vegetables, broth-based soups, and nonfat dairy,” White explains.
This slowly unfurling literary portal is the work of the ship’s California-based interior architect Richard Riveire of Rottet Studio, who designed the spaces, and Heywood Hill, a nearly century ...
