If random sort needed, use NEWID() instead. value_expression specifica la colonna in base alla quale viene partizionato il set di risultati.value_expression specifies the column by which the result set is partitioned. This is kinda like using a GROUP BY. PARTITION BY value_expressionPARTITION BY value_expression ROW_NUMBER and RANK are similar. NTILE (Transact-SQL)NTILE (Transact-SQL). The order, in which the row numbers are applied, is determined by the ORDER BY expression.
