/** SQL parser.
 *
 * The Gda::SqlParser is an object dedicated to creating Gda::Statement and
 * Gda::Batch objects from SQL strings. The actual contents of the parsed
 * statements is represented as Gda::SqlStatement structures (which can be
 * obtained from any Gda::Statement through the "structure" property).
 *
 * Gda::SqlParser parsers can be created by calling Gda::ServerProvider::create_parser()
 * for a provider adapted SQL parser, or using create() for a general purpose SQL parser.
 *
 * The Gda::SqlParser can either work in "parse" mode where it will try to parse
 * the SQL string, or in "delimiter" mode where it will only attempt at delimiting
 * SQL statements in a string which may contain several SQL statements (usually
 * separated by a semi column). If operating in "parser" mode, and the parser
 * can't correctly parse the string, then it will switch to the "delimiter" mode
 * for the next statement in the string to parse (and create a STATEMENT_UNKNOWN statement).
 *
 * The Gda::SqlParser object parses and analyses SQL statements and reports the
 * following statement types:
 *
 * - SELECT (and COMPOUND select), INSERT, UPDATE and DELETE SQL statements should be completely parsed.
 *
 * - Transaction related statements (corresponding to the BEGIN, COMMIT,
 *   ROLLBACK, SAVEPOINT, ROLLBACK SAVEPOINT and DELETE SAVEPOINT) are parsed and a
 *   minimalist structure is created to extract some information (that structure is not enough per-se to re-create the complete SQL statement).
 *
 * Any other type of SQL statement (CREATE TABLE, ...) creates a GdaStatement of
 * type STATEMENT_UNKNOWN, and it only able to locate place holders (variables)
 * and end of statement marks.
 *
 * NOTE: Any SQL of a type which should be parsed which but which creates a Gda::Statement
 * of type GDA_SQL_STATEMENT_UNKNOWN (check with Gda::Statement::get_statement_type())
 * should be reported as a bug.
 *
 * The Gda::SqlParser object recognizes place holders (variables), which can later
 * be queried and valued using Gda::Statement::get_parameters().
 * See the syntax description for the underlying <a href="http://library.gnome.org/devel/libgda/stable/GdaSqlParser.html#GdaSqlParser.description">GdaSqlParser</a>.
