HCL OneDB™ ODBC Driver GuideThe HCL OneDB™ ODBC Driver Programmer's Manual serves as a user guide and reference for HCL OneDB™ ODBC Driver, which is the HCL OneDB™ implementation of the Microsoft™ Open Database Connectivity (ODBC) interface, Version 3.0.
Rows and collectionsRows and collections are composite values that consist of one or more elements.
Allocating and binding a row or collection bufferWhen you retrieve a row or collection, the database server puts the row or collection into a buffer that is local to your HCL OneDB™ ODBC Driver application.
Buffers and memory allocationWhen you retrieve data into a buffer that already contains a row or collection, HCL OneDB™ ODBC Driver does not reuse the same buffer.

Buffers and memory allocation

When you retrieve data into a buffer that already contains a row or collection, HCL OneDB™ ODBC Driver does not reuse the same buffer.

Instead, HCL OneDB ODBC Driver performs the following steps:

Creates a row or collection buffer.
Associates the new buffer with the given buffer handle.
Deallocates the original buffer.
