What is
HCL OneDB™
ODBC Driver?
Open Database Connectivity (ODBC) is a specification for a database application programming interface (API).
ODBC component overview
ODBC with the
HCL® OneDB® ODBC Driver
includes several components.
HCL OneDB™
ODBC Driver with the DMR
HCL® OneDB® ODBC Driver
includes a Driver Manager Replacement (DMR) library. The DMR replaces the driver manager on platforms where no driver manager is available.
HCL OneDB™
ODBC Driver components
HCL® OneDB® ODBC Driver
includes the four components.
The
HCL OneDB™
ODBC Driver API
An application uses the
HCL® OneDB® ODBC Driver
API to make a connection to a data source, send SQL statements to a data source, process result data dynamically, and terminate a connection.
Connection pooling and authentication
Global Language Support
HCL OneDB™
products can support many languages, cultures, and code sets. Global Language Support (GLS) provides support for all language- and culture-specific information.
X/Open standard interface
In addition to the standard ODBC functions, the
HCL® OneDB® ODBC Driver
also supports the additional functions.
External authentication
For
HCL OneDB™
Version 10.0 and later, you can implement external authentication through the
HCL® OneDB® ODBC Driver
.
Bypass ODBC parsing
You can bypass ODBC parsing by using several options.
BufferLength in character for SQLGetDiagRecW
The
SQLGetDiagRecW
API returns diagnostic information in the output buffer, where the BufferLength parameter is the length of buffer allocated.
HCL OneDB™
and ISAM error descriptions in SQLGetDiagRec
The
SQLGetDiagRec
API returns diagnostic information in the output buffer, where the error description is for the
HCL OneDB™
error message.
Improved performance for single-threaded applications
You are likely to improve the performance of single-threaded applications by using the SINGLETHREADED connection parameter. The value is off by default.
Partially supported and unsupported ODBC features
HCL® OneDB® ODBC Driver
supports partial implementation of several ODBC features.
Transaction processing
HCL® OneDB® ODBC Driver
implementation of transaction isolation levels and transaction modes is slightly different from the Microsoft™ ODBC implementation of these features.
ODBC cursors
HCL® OneDB® ODBC Driver
supports static and forward cursors but not dynamic and keyset-driven cursors.
ODBC bookmarks
A
bookmark
is a value that identifies a row of data.
SQLBulkOperations
HCL® OneDB® ODBC Driver
supports only the SQL_ADD argument of
SQLBulkOperations
.
SQLDescribeParam
SQLDescribeParam
is an ODBC API which returns metadata for the parameters of a query.
Unsupported Microsoft™ ODBC driver features
HCL® OneDB® ODBC Driver
does not support implementation of the certain Microsoft™ ODBC driver features.
Configure data sources
These topics explain how to configure a data source (DSN) on UNIX™ and Windows™ for
HCL® OneDB® ODBC Driver
.
Data types
These topics contain information about the data types that are supported by
HCL® OneDB® ODBC Driver
.
Smart large objects
These 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.
