Systems, methods and articles of manufacture are disclosed for batching heterogeneous database commands. The heterogeneous database commands may include at least two database command types. Further, at least two of the heterogeneous database commands may include host variables. A request to execute the heterogeneous database commands may be received. The heterogeneous database commands may be sent to a database system for execution, responsive to the request.

Batching heterogeneous database commands

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.

Generating information on database queries in source code into object code compiled from the source code

Provided are techniques for generating a result set. A statement that includes at least one statement pattern is received, wherein each statement pattern is a template that indicates how a statement is to be modified for execution against a data store and wherein each statement pattern modifies program logic and control flow. Each statement pattern is expanded to generate one or more new statements, wherein each statement pattern is capable of being expanded to zero or more statement patterns. The one or more new statements are executed against a data store to obtain a result set. It is determined whether to modify the result set based on the at least one statement pattern. In response to determining that the result set is to be modified, modifying the result set.

Statement generation using statement patterns

Provided are techniques for storing data. Invocation of a data access service is received, wherein the invocation identifies a data structure storing one or more data elements having a data format. An update handler to be plugged into a data access framework is identified, wherein the update handler processes data elements having the data format. Under control of the update handler, data elements are accessed in the data structure; one or more statements for storing the data elements into the data store are determined; and the one or more statements are forwarded to the data access framework.
