Source code of example programs using ODB API are maintained in ODB API git repository.
ODB API examples
This directory contains examples of usage of ODB API.
The C API (Application Programming Interface) has been inspired by sqlite3 API. It consists of a set of C functions and constants defined in header file
odbql.h. This API is intended to be used in C and C++ programs. It is also a basis of Fortran and Python ODB API interfaces' implementations.
Generally, the ODB API functions that are part of public interface start with
odbql_ prefix. All of them have an equivalent in the public interface of sqlite3 that has a
sqlite3_ prefix and a simillar syntax (parameters) and semantics.
Similarly, most status and error codes, as well as numerical codes denoting column types, defined in
odbql.h with macros prefixed with
ODBQL_, have an equivalent macro in sqlite3 that starts with
SQLITE_ and has the same meaning and numerical value. However, due to differences between ODB API and sqlite3 it was necessary to add some ODB API specific status codes, at this time these are
ODBQL_BITFIELD (an ODB specific data type).
odbql_c_example.c for complete examples of how to read, write and process data with ODB API SQL engine using ODB API C/C++ interface.
Fortran ODB API is a set of Fortran 95 subroutines and functions wrapping the C API described above. The subroutines and functions are in a module
odbql_wrappers, and have the same names as their C equivalents.
odbql_fortran_example.f90 for example programs using module
Python interface of ODB API implements PEP 249 -- Python Database API Specification v2.0.
odbql_python_example.py for example code using the module.
