In this subsection, assume that the Unicode application is limited to SQL_C_WCHAR data binding and a Unicode session character set is used.
The following figure depicts the programming model for Unicode applications accessing ODBC Driver for Teradata.
- SQL-Text and SQL_C_WCHAR character data flows between the Unicode ODBC application and the ODBC Driver Manager
- The ODBC Driver Manager does not convert SQL-Text or the character strings and passes them as is to the ODBC driver
- ODBC Driver for Teradata does not convert SQL-Text or character strings and passes them as is to Teradata Database
