The Informix® GLS User's Guide describes the Global Language Support (GLS) feature available in Informix products.
The Informix® GLS API Programmer's Guide describes the global language support (GLS) application programming interface (API) available in Informix ESQL/C and HCL Informix DataBlade® modules.
The Informix® Object Interface for C++ Programmer's Guide describes how to develop HCL Informix client applications by using the object-oriented C++ programming language.
Open Database Connectivity (ODBC) is a specification for a database application programming interface (API).
ODBC with the Informix® ODBC Driver includes several components.
Informix® ODBC Driver includes a Driver Manager Replacement (DMR) library. The DMR replaces the driver manager on platforms where no driver manager is available.
Informix® ODBC Driver includes the four components.
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.
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
HCL Informix® products can support many languages, cultures, and code sets. Global Language Support (GLS) provides support for all language- and culture-specific information.
In addition to the standard ODBC functions, the Informix® ODBC Driver also supports the additional functions.
For HCL Informix® Version 10.0 and later, you can implement external authentication through the Informix ODBC Driver.
You can bypass ODBC parsing by using several options.
The SQLGetDiagRecW API returns diagnostic information in the output buffer, where the BufferLength parameter is the length of buffer allocated.
The SQLGetDiagRec API returns diagnostic information in the output buffer, where the error description is for the HCL Informix® error message.
You are likely to improve the performance of single-threaded applications by using the SINGLETHREADED connection parameter. The value is off by default.
Informix® ODBC Driver implementation of transaction isolation levels and transaction modes is slightly different from the Microsoft™ ODBC implementation of these features.
Informix® ODBC Driver supports static and forward cursors but not dynamic and keyset-driven cursors.
A bookmark is a value that identifies a row of data.
SQLDescribeParam is an ODBC API which returns metadata for the parameters of a query.
Informix® ODBC Driver does not support implementation of the certain Microsoft™ ODBC driver features.
These topics explain how to configure a data source (DSN) on UNIX™ and Windows™ for Informix® ODBC Driver.
These topics contain information about the data types that are supported by Informix® ODBC Driver.
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 are composite values that consist of one or more elements.
These topics describe the Informix® ODBC Driver client functions. Use these functions to access and manipulate smart large objects and rows and collections.
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.
These topics suggest ways to improve performance of Informix® ODBC Driver applications.
These topics describe the Informix® ODBC Driver error messages.
These topics provide a brief overview of the Unicode standard and shows how it is used within ODBC applications.
The Data Server Provider for .NET DB2® provider option is the preferred Informix® provider for developing new applications.
