Client APIs and toolsYou can use the HCL OneDB™ implementation of client APIs to develop applications for HCL OneDB™ database servers.
ESQL/C GuideThe HCL OneDB™ ESQL/C Programmer's Manual explains how to use , the HCL OneDB™ implementation of Embedded Structured Query Language (SQL) for C (ESQL/C), to create client applications with database-management capabilities.

Smart large objectsA smart large object is a data type that stores large, non-relational data objects such as images, sound clips, documents, graphics, maps and other large objects, and allows you to perform read, write, and seek operations on those objects.
Creating a smart large object

Creating a smart large object

About this task

Perform the following steps to create a smart large object:

Allocate an LO-specification structure with the ifx_lo_def_create_spec() function.
Ensure that the LO-specification structure contains the desired storage characteristics for the new smart large object.
Create an LO-pointer structure for the new smart large object and open the smart large object with the ifx_lo_create() function.
Write the data for the new smart large object to the open smart large object with the ifx_lo_write() or ifx_lo_writewithseek() function.
Save the new smart large object in a column of the database.
Deallocate the LO-specification structure with the ifx_lo_spec_free() function.
