Abstract
In an embodiment, a database management system (DBMS) hosted by a computer receives a request to execute a database statement and responsively generates an interpretable execution plan that represents the database statement. The DBMS decides whether execution of the database statement will or will not entail interpreting the interpretable execution plan and, if not, the interpretable execution plan is compiled into object code based on partial evaluation. In that case, the database statement is executed by executing the object code of the compiled plan, which provides acceleration. In an embodiment, partial evaluation and Turing-complete template metaprogramming (TMP) are based on using the interpretable execution plan as a compile-time constant that is an argument for a parameter of an evaluation template.
