In this subsection, assume that the Unicode application is limited to SQL_C_WCHAR data binding and a Unicode session character set is used.
Figure 2 depicts the programming model for Unicode applications accessing ODBC Driver for Teradata.
Figure 2: Programming Model for Unicode Applications
1 SQL-Text and SQL_C_WCHAR character data flows between the Unicode ODBC application and the ODBC Driver Manager
2 The ODBC Driver Manager does not convert SQL-Text or the character strings and passes them as is to the ODBC driver
3 ODBC Driver for Teradata does not convert SQL-Text or character strings and passes them as is to Teradata Database
