/** SQL Parser Functions for phpMyAdmin
 *
 * Copyright 2002 Robin Johnson <hide@address.com>
 * http://www.orbis-terrarum.net/?l=people.robbat2
 *
 * These functions define an SQL parser system, capable of understanding and
 * extracting data from a MySQL type SQL query.
 *
 * The basic procedure for using the new SQL parser:
 * On any page that needs to extract data from a query or to pretty-print a
 * query, you need code like this up at the top:
 *
 * ($sql contains the query)
 * $parsed_sql = PMA_SQP_parse($sql);
 *
 * If you want to extract data from it then, you just need to run
 * $sql_info = PMA_SQP_analyze($parsed_sql);
 *
 * lem9: See comments in PMA_SQP_analyze for the returned info
 *       from the analyzer.
 *
 * If you want a pretty-printed version of the query, do:
 * $string = PMA_SQP_formatHtml($parsed_sql);
 * (note that that you need to have syntax.css.php included somehow in your
 * page for it to work, I recommend '<link rel="stylesheet" type="text/css"
 * href="syntax.css.php" />' at the moment.)

/* Description of analyzer results by lem9
 *
 * db, table, column, alias
 * ------------------------
 *
 * Inside the $subresult array, we create ['select_expr'] and ['table_ref'] arrays.
 *
 * The SELECT syntax (simplified) is
 *
 * SELECT
 *    select_expression,...
 *    [FROM [table_references]
 *
 *
 * ['select_expr'] is filled with each expression, the key represents the
 * expression position in the list (0-based) (so we don't lose track of
 * multiple occurences of the same column).
 *
 * ['table_ref'] is filled with each table ref, same thing for the key.
 *
 * I create all sub-values empty, even if they are
 * not present (for example no select_expression alias).
 *
 * There is a debug section at the end of loop #1, if you want to
 * see the exact contents of select_expr and table_ref
 *
 * queryflags
 * ----------
 *
 * In $subresult, array 'queryflags' is filled, according to what we
 * find in the query.
 *
 * Currently, those are generated:
 *
 * ['queryflags']['need_confirm'] = 1; if the query needs confirmation
 * ['queryflags']['select_from'] = 1;  if this is a real SELECT...FROM
 * ['queryflags']['distinct'] = 1;     for a DISTINCT
 * ['queryflags']['union'] = 1;        for a UNION
 * ['queryflags']['join'] = 1;         for a JOIN
 * ['queryflags']['offset'] = 1;       for the presence of OFFSET
 *
 * query clauses
 * -------------
 *
 * The select is splitted in those clauses:
 * ['select_expr_clause']
 * ['from_clause']
 * ['group_by_clause']
 * ['order_by_clause']
 * ['having_clause']
 * ['where_clause']
 *
 * The identifiers of the WHERE clause are put into the array
 * ['where_clause_identifier']
 *
 * For a SELECT, the whole query without the ORDER BY clause is put into
 * ['unsorted_query']
 *
 * foreign keys
 * ------------
 * The CREATE TABLE may contain FOREIGN KEY clauses, so they get
 * analyzed and ['foreign_keys'] is an array filled with
 * the constraint name, the index list,
 * the REFERENCES table name and REFERENCES index list,
 * and ON UPDATE | ON DELETE clauses
 *
 * position_of_first_select
 * ------------------------
 *
 * The array index of the first SELECT we find. Will be used to
 * insert a SQL_CALC_FOUND_ROWS.
 *
 * create_table_fields
 * -------------------
 *
 * For now, mostly used to detect the DEFAULT CURRENT_TIMESTAMP and
 * ON UPDATE CURRENT_TIMESTAMP clauses of the CREATE TABLE query.
 * An array, each element is the identifier name.
 * Note that for now, the timestamp_not_null element is created
 * even for non-TIMESTAMP fields.
 *
 * Sub-elements: ['type'] which contains the column type
 *               optional (currently they are never false but can be absent):
 *               ['default_current_timestamp'] boolean
 *               ['on_update_current_timestamp'] boolean
 *               ['timestamp_not_null'] boolean
 *
 * section_before_limit, section_after_limit
 * -----------------------------------------
 *
 * Marks the point of the query where we can insert a LIMIT clause;
 * so the section_before_limit will contain the left part before
 * a possible LIMIT clause
 *
 *
