SQL Anywhere provides support for ODBC 3.5, which is supplied as part of the Microsoft Data Access Kit 2.7.
ODBC features are arranged according to level of conformance. Features are either Core, Level 1, or Level 2, with Level 2 being the most complete level of ODBC support. These features are listed in the ODBC Programmer's Reference, which is available from Microsoft Corporation as part of the ODBC software development kit or from the Microsoft web site, at http://msdn.microsoft.com/library/en-us/odbc/htm/odbcabout_this_manual.asp.
SQL Anywhere supports the ODBC 3.5 specification.
Core conformance SQL Anywhere supports all Core level features.
Level 1 conformance SQL Anywhere supports all Level 1 features, except for asynchronous execution of ODBC functions.
SQL Anywhere supports multiple threads sharing a single connection. The requests from the different threads are serialized by SQL Anywhere.
Level 2 conformance SQL Anywhere supports all Level 2 features, except for the following:
Three part names of tables and views. This is not applicable for SQL Anywhere.
Asynchronous execution of ODBC functions for specified individual statements.
Ability to time out login requests and SQL queries.
Applications developed using older versions of ODBC continue to work with SQL Anywhere and the newer ODBC driver manager. The new ODBC features are not provided for older applications.
Microsoft Windows includes an ODBC driver manager. For Unix, an ODBC driver manager is supplied with SQL Anywhere.
