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.
What is HCL OneDB™ ESQL/C?
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.
Data structures for smart large objects
The LO-specification structureBefore you create a new smart large object, you must allocate an LO-specification structure with the ifx_lo_def_create_spec() function.
Deallocate the LO-specification structureAfter you are finished with an LO-specification structure, deallocate the resources assigned to it with the ifx_lo_spec_free() function. When the resources are freed, they can be reallocated to other structures that your program needs.
