II. 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 Ole DB client, this feature can be primarily accessed using the GetParameterInfo method of the ICommandWithParameters interface in Command class to obtain the metadata for the parameters in a query.

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.
