- * Analyzes SQL queries
- *
- * 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
- *
- * @access public
- * @param array The SQL queries
- * @return array The analyzed SQL queries
