Private Methods

Method	Description
FromSQL2Chars ( string sql ) : char[]
NextTokenInternal ( ) : MySqlToken
ScanIdentifierFromNumber ( int initOffset, int initSize ) : void	NOTE: id dosn't include '.' for sake of performance issue (based on shaojin.wensj's design). However, it is not convenient for MySql compatibility. e.g. ".123f" will be regarded as ".123" and "f" in MySql, but in this MySqlLexer , it will be "." and "123f" because ".123f" may be part of "db1.123f" and "123f" is the table name.
