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.
