Exception thrown when mysql function name as a column name

[geshen]

For example:

match is a mysql function, if some table include match as its column, then start_createindex.sh will throw a exception that tells synctax error around
select count(distinct(match)) from table_name.

In fact, the correct syntax should be select count(distinct(match)) from table_name.

Solution may be:

1. setup a rule that column name can't be any function name
2. add necessary quote for this kind of column
