Map To WVarcharCData ODBC Driver for Amazon Marketplace 2019 - Build 19.0.7354
This property controls whether or not string types map to SQL_WVARCHAR instead of SQL_VARCHAR. This property is set by default.
String columns must be mapped to SQL_WVARCHAR to accommodate various international character sets, so MapToWVarchar is set to true by default. You may set it to false to use SQL_VARCHAR instead.
