Embodiments of the present invention relate to dynamically merging executable structures in a database system. In one embodiment, there is provided a method of dynamically merging executable structures in a database system that includes, in response to a query to the database system, extracting a stem and a branch of a query statement. The query statement includes query conditions, and the branch includes at least a subset of the query conditions. An executable structure of the stem is obtained from a cache of the database system, and an executable structure of the branch is generated. The executable structure of the stem and the executable structure of the branch are merged into a runtime executable structure.
