II. IBM Informix Database Server Compatibility

Version 3.82 of IBM Informix ODBC Driver has been tested with the following database server configurations:


III. New Features

Support for DYNAMIC QUERY EXTENSION
The Dynamic Query Extension feature introduces support for describing input parameters of a prepared statement. This is an enhancement of the Dynamic SQL functionality of the server. This feature requires IDS server side support for "Dynamic Query Extension", hence it will work only with IDS version 9.4 or above.
For an ODBC client, this feature will be primarily accessed using the SQLDescribeParam API (level 1 conformance) to obtain the metadata for the parameters in a query. The driver will report SQL_ATTR_AUTO_IPD as SQL_TRUE when connecting to a server that has the Dynamic Query Extension feature implemented

Support for SQL 99 Joins
The SQL 99 Joins feature extends support for SQL joins within & outside an escape sequence. This feature requires IDS server side support for "SQL 99 joins", hence it will work only with IDS version 9.4 or above.

Support for 32k Lvarchar
The 32k Lvarchar feature extends the ability of lvarchar columns to hold upto 32k bytes of data. This feature requires IDS server side support for "32k Lvarchar", hence it will work only with IDS version 9.4 or above.
