* 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 '' 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
* ['queryflags']['procedure'] = 1; for the presence of PROCEDURE
*
* query clauses
* -------------
*
* The select is splitted in those clauses:
* ['select_expr_clause']
* ['from_clause']
* ['group_by_clause']
* ['order_by_clause']
* ['having_clause']
* ['limit_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
*
*
* End of description of analyzer results
