result::get<nanodbc::string>(string const& column_name) truncat to 255 bytes

[guleishanks]

Environment

• nanodbc version:2.14.0
• DBMS name/version:hive3.1.3
• ODBC connection string:default
• OS and Compiler:centos 7, gcc 8.3.1
• CMake settings: default

Actual behavior

result::getnanodbc::string(string const& column_name)，if the string type column in hive have a value of more than 255bytes，then the "result::getnanodbc::string" function will truncat to 255.

Expected behavior

"result::getnanodbc::string" function work well when more than 255 bytes.

Minimal Working Example

DBMS name/version:hive3.1.3

What driver and its version? I've never used Hive.

ODBC connection string:default

w/ or w/o Unicode enabled?

if the string type column in hive

What type exactly? Does it happens for any text data type?

Please, try do better.

the problem has been solved , I change the hive column type from 'string' to 'varchar' , then the 'result::getnanodbc::string(string const& column_name)' function works well.
