Token parsing incorrect behavior
Description: I have been writing an SQL tokenizer for the phpMyAdmin project, on which I am a core developer. I used this page (Manual 6.1.2 Database, Table, Index, Column, and Alias Names) for reference as to what a valid token was. As well as this reference on SQL User Variables (Manual 6.1.4 User Variables). Most specificly, it states that an identifier CAN start with a number. Ergo, 0xff could be an identifer or a hexadecimal number. However, 0xgff and 0xffg are not valid hexadecimal numbers, and are only valid as identifiers. Use my SQL fragment below, and note the results of the two SELECT queries. While the 0xgff column produces correct results, The 0xfge column does not. The column title is garbled. How-To-Repeat: CREATE TABLE `strtest` ( `0xfge` int(10) unsigned zerofill NOT NULL auto_increment, `0xgff` varchar(255) NOT NULL default '', PRIMARY KEY (`0xfge`) ) TYPE=MyISAM; INSERT INTO strtest VALUES (01, 'Foo'); SELECT * FROM strtest; SELECT 0xfge,0xgff FROM strtest; Fix: Make tokens that fail as being hexadecimal numbers be recognized as identifiers only.
