Abstract
The present disclosure involves systems, software, and computer implemented methods for managing database query plans with dynamic conditions. One example method includes receiving a request to process a query based on a dynamic condition. In response to determining that a plan cache does not include a cached query plan for the query, query plan compilation is triggered to generate a query plan. In response to determining that a cached query plan exists, for each query view, a condition provider procedure is invoked to generate a first filter string. First filter strings are compared to corresponding second filter strings in the cached plan. In response to determining that a first filter string does not match the corresponding second filter string, query plan compilation is triggered. In response to determining that each filter string matches each corresponding second filter string, the database query is executed using the cached query plan.
