/*
 * fakesql.h --
 *
 *	Include file that defines the subset of SQL/CLI that TDBC
 *	uses, so that tdbc::odbc can build without an explicit ODBC
 *	dependency. It comprises only data type, constant and
 *	function declarations.
 *
 * The programmers of this file believe that it contains material not
 * subject to copyright under the doctrines of scenes a faire and
 * of merger of idea and expression. Accordingly, this file is in the
 * public domain.
