Client APIs and toolsYou can use the HCL OneDB™ implementation of client APIs to develop applications for HCL OneDB™ database servers.
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.
Smart large objectsThese topics describe how to store, create, and access a smart large object; how to transfer smart-large-object data; how to retrieve the status of a smart large object; and how to read or write a smart large object to or from a file.
Access a smart large objectThis section describes how to select, open, delete, modify, and close a smart large object by using either the standard ODBC API or by using ifx_lo functions.
The ifx_lo functionsThis section describes how to select, open, delete, modify, and close a smart large object by using ifx_lo functions.
Select a smart large object using ifx_lo functionsA SELECT statement does not perform the actual output for the smart-large-object data. It does, however, establish a means for the application to identify a smart large object so that the application can then perform operations on the smart large object.

Select a smart large object using ifx_lo functions

A SELECT statement does not perform the actual output for the smart-large-object data. It does, however, establish a means for the application to identify a smart large object so that the application can then perform operations on the smart large object.

The following figure shows how the database server transfers the data of a smart large object to the application.

This graphic illustrates the steps necessary to transfer smart-large-object data from a database server to a client application. This graphic is composed of two boxes in a vertical line and connected by a down facing arrow. The first box contains these two steps: 1. Execute SELECT statement. 2. Obtain smart-large-object pointer structure. The second box contains this step: 3. Use client functions to access data through the smart-large-object pointer structure. — Figure 1: Transferring smart-large-object data from database server to client application
