In the following section, assume that the ANSI application is limited to SQL_C_CHAR data binding and a non-Unicode session character set is used. The following figure depicts the programming model for ODBC Driver for Teradata:



  1. SQL-Text and SQL_C_CHAR character data flows between the ODBC Application and the ODBC Driver Manager
  2. The ODBC Driver Manager:
    • Converts the SQL-Text to Unicode and passes it to the ODBC Driver
    • Does not convert the SQL_C_CHAR data and passes it as is to the ODBC Driver
  3. The ODBC Driver for Teradata Database:
    • Converts the SQL-Text from Unicode to Session Character Set
    • Does not convert the SQL_C_CHAR data and passes it as is to Teradata Database
