Abstract
A query processing system is operable to receive a query expression that includes a call to a computing window function indicating an expression that includes a column reference that includes a prior row index identifier. The computing window function is executed based on accessing at ordered set of rows of the database indicated in the call to the computing window function. An output column is generated based on generating output for each row of a set of rows in the ordered set of rows by evaluating the expression based on performing at least one operation upon a column value, determined based on applying the column reference, of a previous row in the ordered set of rows. A query resultant for the query expression is generated based on the output column generated for the rows in the ordered set of rows.
