Some of the restrictions for using ODBC Driver for Teradata include:
  • The SET SESSION DateForm command is not allowed in a multi-statement request
  • The time zone value for TIME WITH TIME ZONE and TIMESTAMP WITH TIME ZONE must be converted to an ODBC C character type. The standard ODBC C time and timestamp types do not have a time zone component
  • (Windows) Since ODBC Driver for Teradata does not support PMPC commands, asynchronous niching (priority of execution) of a query is not supported, but self-niching queries are supported.
  • The Teradata TIME type allows fractional seconds, but there is limited support for fractional seconds of TIME in standard ODBC. As an extension to standard ODBC, ODBC Driver for Teradata preserves fractional seconds in conversions between character ODBC C data types and SQL_TYPE_TIME.
