3 /** SQL Parser Functions for phpMyAdmin
5 * These functions define an SQL parser system, capable of understanding and
6 * extracting data from a MySQL type SQL query.
8 * The basic procedure for using the new SQL parser:
9 * On any page that needs to extract data from a query or to pretty-print a
10 * query, you need code like this up at the top:
12 * ($sql contains the query)
13 * $parsed_sql = PMA_SQP_parse($sql);
15 * If you want to extract data from it then, you just need to run
16 * $sql_info = PMA_SQP_analyze($parsed_sql);
18 * See comments in PMA_SQP_analyze for the returned info
19 * from the analyzer.
21 * If you want a pretty-printed version of the query, do:
22 * $string = PMA_SQP_formatHtml($parsed_sql);
23 * (note that that you need to have syntax.css.php included somehow in your
24 * page for it to work, I recommend '<link rel="stylesheet" type="text/css"
25 * href="syntax.css.php" />' at the moment.)
27 * @package PhpMyAdmin

893 * db, table, column, alias
894 * ------------------------
896 * Inside the $subresult array, we create ['select_expr'] and ['table_ref'] arrays.
898 * The SELECT syntax (simplified) is
900 * SELECT
901 * select_expression,...
902 * [FROM [table_references]
905 * ['select_expr'] is filled with each expression, the key represents the
906 * expression position in the list (0-based) (so we don't lose track of
907 * multiple occurences of the same column).
909 * ['table_ref'] is filled with each table ref, same thing for the key.
911 * I create all sub-values empty, even if they are
912 * not present (for example no select_expression alias).
914 * There is a debug section at the end of loop #1, if you want to
915 * see the exact contents of select_expr and table_ref
917 * queryflags
918 * ----------
920 * In $subresult, array 'queryflags' is filled, according to what we
921 * find in the query.
923 * Currently, those are generated:
925 * ['queryflags']['need_confirm'] = 1; if the query needs confirmation
926 * ['queryflags']['select_from'] = 1; if this is a real SELECT...FROM
927 * ['queryflags']['distinct'] = 1; for a DISTINCT
928 * ['queryflags']['union'] = 1; for a UNION
929 * ['queryflags']['join'] = 1; for a JOIN
930 * ['queryflags']['offset'] = 1; for the presence of OFFSET
931 * ['queryflags']['procedure'] = 1; for the presence of PROCEDURE
933 * query clauses
934 * -------------
936 * The select is splitted in those clauses:
937 * ['select_expr_clause']
938 * ['from_clause']
939 * ['group_by_clause']
940 * ['order_by_clause']
941 * ['having_clause']
942 * ['limit_clause']
943 * ['where_clause']
945 * The identifiers of the WHERE clause are put into the array
946 * ['where_clause_identifier']
948 * For a SELECT, the whole query without the ORDER BY clause is put into
949 * ['unsorted_query']
951 * foreign keys
952 * ------------
953 * The CREATE TABLE may contain FOREIGN KEY clauses, so they get
954 * analyzed and ['foreign_keys'] is an array filled with
955 * the constraint name, the index list,
956 * the REFERENCES table name and REFERENCES index list,
957 * and ON UPDATE | ON DELETE clauses
959 * position_of_first_select
960 * ------------------------
962 * The array index of the first SELECT we find. Will be used to
963 * insert a SQL_CALC_FOUND_ROWS.
965 * create_table_fields
966 * -------------------
968 * Used to detect the DEFAULT CURRENT_TIMESTAMP and
969 * ON UPDATE CURRENT_TIMESTAMP clauses of the CREATE TABLE query.
970 * Also used to store the default value of the field.
971 * An array, each element is the identifier name.
972 * Note that for now, the timestamp_not_null element is created
973 * even for non-TIMESTAMP fields.
975 * Sub-elements: ['type'] which contains the column type
976 * optional (currently they are never false but can be absent):
977 * ['default_current_timestamp'] boolean
978 * ['on_update_current_timestamp'] boolean
979 * ['timestamp_not_null'] boolean
981 * section_before_limit, section_after_limit
982 * -----------------------------------------
984 * Marks the point of the query where we can insert a LIMIT clause;
985 * so the section_before_limit will contain the left part before
986 * a possible LIMIT clause
