Informix® ODBC Driver
and describe its advantages and architecture. The topics also describe conformance, isolation and lock levels, libraries, and environment variables.
What is
HCL Informix®
ODBC Driver?
Open Database Connectivity (ODBC) is a specification for a database application programming interface (API).
ODBC component overview
ODBC with the
Informix® ODBC Driver
includes several components.
HCL Informix®
ODBC Driver with the DMR
Informix® ODBC Driver
includes a Driver Manager Replacement (DMR) library. The DMR replaces the driver manager on platforms where no driver manager is available.
HCL Informix®
ODBC Driver components
Informix® ODBC Driver
includes the four components.
The
HCL Informix®
ODBC Driver API
An application uses the
Informix® 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
Starting CSDK 4.50.xC2 onwards, Informix ODBC driver also supports Connection Pooling capabilities. One may decide to use either Connection Pooling capabilities provided by ODBC Driver Manager or newly added capabilities in Informix ODBC Driver
Global Language Support
HCL Informix®
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
Informix® ODBC Driver
also supports the additional functions.
External authentication
For
HCL Informix®
Version 10.0 and later, you can implement external authentication through the
Informix® 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.
Informix®
and ISAM error descriptions in SQLGetDiagRec
The
SQLGetDiagRec
API returns diagnostic information in the output buffer, where the error description is for the
HCL Informix®
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
Informix® ODBC Driver
supports partial implementation of several ODBC features.
Transaction processing
Informix® ODBC Driver
implementation of transaction isolation levels and transaction modes is slightly different from the Microsoft™ ODBC implementation of these features.
ODBC cursors
Informix® 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
Informix® 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
Informix® 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
Informix® ODBC Driver
.
Data types
These topics contain information about the data types that are supported by
Informix® 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.
Rows and collections
Rows and collections are composite values that consist of one or more elements.
Client functions
These topics describe the
Informix® ODBC Driver
client functions. Use these functions to access and manipulate smart large objects and rows and collections.
Application tracking in ODBC
Set the
CLIENT_LABEL
environment variable in CSDK 4.50.xC4 onwards to assign a character string to ODBC client session and identify that character string on the database server. You can use this variable to distinguish one database session from the other.
Improve application performance
These topics suggest ways to improve performance of
Informix® ODBC Driver
applications.
Error messages
These topics describe the
Informix® ODBC Driver
error messages.
Unicode
These topics provide a brief overview of the Unicode standard and shows how it is used within ODBC applications.
