The Adaptive Server ODBC Driver conforms to ODBC 3.52 specification.
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 Microsoft ODBC Programmer's Reference.
The Adaptive Server ODBC Driver meets Level 2 conformance with these exceptions:
Level 1 conformance – The Adaptive Server ODBC Driver supports all Level 1 features except SQLSetPos with SQL_REFRESH.
Level 2 conformance – The Adaptive Server ODBC Driver supports all Level 2 features except for using bookmarks in SQLBulkOperations (SQL_FETCH_BY_BOOKMARK, SQL_UPDATE_BY_BOOKMARK, SQL_DELEET_BY_BOOKMARK).
Applications developed using older versions of ODBC continue to work with the Adaptive Server ODBC Driver and the newer ODBC Driver Manager. The new ODBC features are not available for older applications.
