/**
Declarations for interfacing with the ODBC library.

Adapted with minimal changes from the work of David L. Davis
(refer to the $(HTTP
forum.dlang.org/post/cfk7ql$(DOLLAR)1p4n$(DOLLAR)1@digitaldaemon.com,
original announcement)).

`etc.c.odbc.sql` is the the main include for ODBC v3.0+ Core functions,
corresponding to the `sql.h` C header file. It `import`s `public`ly
`etc.c.odbc.sqltypes` for conformity with the C header.

Note: The ODBC library itself not a part of the `dmd` distribution (and
typically not a part of the distribution packages of other compilers
such as `gdc` and `ldc`). To use ODBC, install it per the vendor- and
platform-specific instructions and then use the appropriate command-line
flags (e.g. for dmd, `-L-lodbc` on Posix and `-Lodbc32.lib` on Windows) to link
with the ODBC library. On Windows, using $(D pragma(lib, "odbc32")) in D
code at top level is also appropriate.
