> Every database might have different type or same type but different type 
> name, therefore making every SqlDialect unparse their own data type is a 
> suitable way.
> For example, there is a sql “select cast(col as int) from table” change to 
> hive sql "select cast(col as integer) from table", but "integer" is not 
> allowed in hive.
