Client APIs and toolsYou can use the HCL OneDB™ implementation of client APIs to develop applications for HCL OneDB™ database servers.
ESQL/C GuideThe topics explain how to use HCL OneDB™ ESQL/C, the HCL OneDB™ implementation of Embedded Structured Query Language (SQL) for C (ESQL/C), to create client applications with database-management capabilities. The HCL® OneDB® ESQL/C Programmer's Manual explains how to use HCL OneDB™ ESQL/C, 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?
Simple large objectsA simple large object is a large object that is stored in a blobspace on disk and is not recoverable.
Locate simple large objects in filesYou can locate simple-large-object data in the open or named types of files.
Error returns in loc_status

Error returns in loc_status

One of these flags is passed to the loc_open() function when HCL OneDB™ ESQL/C opens the file. HCL OneDB ESQL/C reads the data and writes it to the current location (which the loc_position field indicates) in the file. If HCL OneDB ESQL/C is unable to read or write to a file, it sets the loc_status field of the locator structure to -463 or -464. If HCL OneDB ESQL/C is unable to close a file, it sets loc_status to -462. HCL OneDB ESQL/C updates the SQLCODE variable with this same value.
