Provided are techniques for static execution of statements. Information from an execution file that describes statements that have been bound to a database during a previous execution of those statements dynamically and describes metadata about the statements is loaded. While executing a program that includes statements, for each of the statements, it is determined whether that statement is bound to the database. In response to determining that the statement is bound to the database, the statement is executed statically using the loaded information. In response to determining that the statement is not bound to the database, the statement is executed dynamically.

Static execution of statements in a program

A method of accessing layers in a multi-layer software architecture including a first layer, a second layer, and a third layer. The method includes: at the third layer, publishing an interface; and at the first layer, before execution of a first function, registering a callback routine with the third layer using the interface.

Cooperative unwrapping across intervening wrappers

Provided are a method, system, and article of manufacture for generating information on database queries in source code into object code compiled from the source code. Source code including query statements to perform operations with respect to a database is translated into executable object code. A statement descriptor for at least one query statement is generated into the object code, wherein the statement descriptor for the at least one query statement includes information on the query statement including the query statement in the source code. The statement descriptors in the object code are processed to output information on the query statements indicated in the statement descriptors.
