Abstract
A query analysis tool determines whether a list of columns within a database is accessed by a query without running the query against the database. Instead of using the database, the query is sent to a query analysis tool that uses a list of columns of interest to resolve ambiguity in the query and then determine if the query potentially accesses the list of columns of interest. If the ambiguity cannot be resolved, then the ambiguous part of the query is determined to not access any of the columns from the list of columns.
