Abstract

The disclosure relates to technology for query compilation in a database management system. A first execution time of code for at least one database query without applying a code generation method is estimated and in response to receiving the at least one database query, and for one or more code generation methods, a compilation cost and a second execution time of the code as modified by the code generation methods is estimated. A cost savings for each of the one or more code generation methods is calculated, where the cost savings is calculated as the first execution time less the second execution time of the code generation method, less the compilation cost of the code generation method. One of the code generation methods or the no code generation method with the highest cost savings is then selected.
