Informix® ODBC Driver supports additional values for some ODBC function arguments.
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 supports partial implementation of several ODBC 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.
This topic provides a link to the Informix 4GL documentation.
These topics describe how to install, load, and use Informix® JDBC Driver to connect to the Informix database from within a Java™ application or applet.
These topics include information about the translated user interface files for Informix® UNIX™ products, locales, and code set conversion tables
These topics describe the software requirements for using Informix® OLE DB Provider, show how to install and configure the provider for your use, and explain how to use Informix OLE DB Provider to enable client applications, such as ActiveX Data Object (ADO) applications and web pages, to access data on the Informix server.
When you embed HCL Informix®, you can use enterprise-class high-availability and high performance with embeddability features such as easy programmability, a small disk and memory footprint, and silent deployment.
Beyond standard relational database objects, HCL Informix® can be extended to handle specialized data types, access methods, routines, and other objects. Informix includes many built-in extensions that are fully integrated in the database server. Informix also provides DataBlade® modules, which are packages of extended database objects for a particular purpose and that are installed separately from the database server. Alternatively, you can create your own user-defined objects for Informix.
In addition to designing and implementing Informix® dimensional databases, you can use tools to create data warehouse applications and optimize your data warehouse queries.
The first step in creating a relational database is to construct a data model, which is a precise, complete definition of the data you want to store. After you prepare your data model, you must implement it as a database and tables. To implement your data model, you first select a data type for each column and then you create a database and tables and populate the tables with data. You can also implement fragmentation strategies and control access to your data.
You can use the popular JSON-oriented query language created by MongoDB to interact with data stored in HCL Informix®.
You can secure your Informix® database server and the data that is stored in your Informix databases. You can encrypt data, secure connections, control user privileges and access, and audit data security.
You can use the HCL Informix® implementation of the SQL language to develop applications for Informix database servers.
Several troubleshooting techniques, tools, and resources are available for resolving problems that you encounter in your HCL Informix® database server environment.
