Abstract
A method and apparatus for implementing a data construct, referred to herein as a "cursor variable", that has many of the attributes of simple variables and that can be used to access active sets of data from a database. Cursor variables identify a current set of data in an active set generated as a result of a database query. A cursor variable can be associated with any one of a number of different queries at any given time during program execution without using a host programming language. As a result, different active sets having different columns, different tables, and/or different predicates may be associated with the same cursor variable using instructions from a single programming language.
