You can use the HCL Informix® implementation of client APIs to develop applications for Informix database servers.
The Informix® GLS User's Guide describes the Global Language Support (GLS) feature available in Informix products.
These topics explain how the GLS feature affects the Informix® implementation of SQL.
The locale affects the collation of built-in SQL character data types.
The choice of locale can affect the character data types.
The Informix® Change Data Capture API Programmer's Guide describes how to program applications to process changed data from HCL Informix databases using the Informix Change Data Capture API.
The Informix® Embedded SQLJ User's Guide contains information about using Informix Embedded SQLJ.
The Informix® ESQL/C Programmer's Manual explains how to use Informix ESQL/C, the Informix implementation of Embedded Structured Query Language (SQL) for C (ESQL/C), to create client applications with database-management capabilities.
The Global Language Support (GLS) feature lets Informix® products handle different languages, cultural conventions, and code sets for Asian, African, European, Latin American, and Middle Eastern countries.
HCL Informix® products establish the client, database, and server locales with information from GLS-related environment variables and from data that is stored in the database.
You must declare names for new database objects (and in some cases, for storage objects, such as dbspaces) when you use data definition language (DDL) statements such as CREATE TABLE, CREATE INDEX, and RENAME COLUMN.
The choice of locale can affect the collating order of NCHAR and NVARCHAR character data types.
The CHAR data type stores character data in a fixed-length field. Data can be a string of single-byte or multibyte letters, numbers, and other characters that are supported by the code set of your database locale.
The VARCHAR data type stores character strings of up to 255 bytes in a variable-length field. Data can consist of letters, numbers, and symbols. CHARACTER VARYING is handled the same as VARCHAR.
The LVARCHAR data type can store character strings of up to 32,739 bytes in a variable-length field. If you specify no maximum size in its declaration, the default upper size limit is 2048 bytes. Data values can include letters, numbers, symbols, white space, and unprintable characters.
The TEXT data type stores any text data. TEXT columns typically store memos, manual chapters, business documents, program source files, and other types of textual information.
The GLS feature allows you to put non-ASCII characters (including multibyte characters) in the elements of an SQL statement.
These topics explain how a locale affects the way that a database server handles the MONEY data type, extended data types, and smart large objects (CLOB and BLOB data types).
The choice of a locale can affect certain SQL data manipulation statements.
HCL Informix® supports a configuration parameter, SQL_LOGICAL_CHAR, whose setting can simplify the use of certain Data Definition Language (DDL) statements of SQL when you declare character data types in locales that support multibyte code sets.
These topics describe how the GLS feature affects the database server.
These topics explain how the GLS feature affects applications that you develop with the Informix® Client Software Development Kit.
These topics explain how the GLS feature affects Informix® ESQL/C, an SQL application programming interface (API).
