Abstract
Techniques and mechanisms for analyzing a plurality of database queries within a database environment. A first statistical evaluation of a first query plan is determined for a first database query with at least one computing device within the database environment. A second statistical evaluation for a second query plan is determined for a second database query. The first statistical evaluation and the second statistical evaluation are compared to determine whether the first query plan matches the second query plan with at least one computing device within the database environment. An indication is stored in a repository of the database environment that the first query matches the second query if the first hash value matches the second hash value. A function that provides the first query plan is determined. If the second query plan is provided by the function that provides the first query plan, data objects referenced by the first query plan and the second query plan if the function provides both the first query plan and the second query plan to determine if the first query plan and the second query plan are syntactically different versions of equivalent database queries. Query stat…
