Abstract

Various embodiments of systems and methods to generate native access plan source code are described herein. In one aspect, a database query is received. A query execution plan, including a parent operator and one or more descendent operators, corresponding to the database query is retrieved. Further, a check is made to determine whether the parent operator and the one or more descendent operators include at least one loop. When both the parent operator and the one or more descendent operators include at least one loop, consume points for the at least one loop are defined. The parent operator and the one or more descendent operators are merged based on consume point types to generate native access plan source code.
