database servers.
GLS User's Guide
These topics describe the Global Language Support (GLS) feature available in
HCL® OneDB®
products.
The
HCL® OneDB® GLS User's Guide
describes the Global Language Support (GLS) feature available in
HCL® OneDB®
products.
SQL features
These topics explain how the GLS feature affects the
HCL® OneDB®
implementation of SQL.
Character data types
The locale affects the collation of built-in SQL character data types.
Other character data types
The choice of locale can affect the character data types.

HCL OneDB™
implementation of client APIs to develop applications for
HCL OneDB™
database servers.
Change Data Capture API Programmer's Guide
These topics describe how to program applications to process changed data from
HCL OneDB™
databases using the
HCL® OneDB® Change Data Capture API
.

.
ESQL/C Guide
The topics explain how to use
HCL OneDB™ ESQL/C
, the
HCL OneDB™
implementation of Embedded Structured Query Language (SQL) for C (ESQL/C), to create client applications with database-management capabilities.
The
HCL® OneDB® ESQL/C Programmer's Manual
explains how to use

GLS User's Guide
These topics describe the Global Language Support (GLS) feature available in
HCL® OneDB®
products.
The
HCL® OneDB® GLS User's Guide
describes the Global Language Support (GLS) feature available in
HCL® OneDB®
products.
GLS fundamentals
The Global Language Support (GLS) feature lets
HCL® OneDB®
products handle different languages, cultural conventions, and code sets for Asian, African, European, Latin American, and Middle Eastern countries.
GLS environment variables
HCL OneDB™
products establish the client, database, and server locales with information from GLS-related environment variables and from data that is stored in the database.
SQL features
These topics explain how the GLS feature affects the
HCL® OneDB®
implementation of SQL.
Name database objects
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.
Character data types
The locale affects the collation of built-in SQL character data types.
Localized collation of character data
The choice of locale can affect the collating order of NCHAR and NVARCHAR character data types.
Other character data types
The choice of locale can affect the character data types.
The CHAR data type
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
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
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
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.
Handle character data
The GLS feature allows you to put non-ASCII characters (including multibyte characters) in the elements of an SQL statement.
Locale-sensitive data types
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).
Data manipulation statements
The choice of a locale can affect certain SQL data manipulation statements.
Data definition statements
HCL OneDB™
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.
Database server features
These topics describe how the GLS feature affects the database server.
General SQL API features (ESQL/C)
These topics explain how the GLS feature affects applications that you develop with the
HCL OneDB™ Client Software Development Kit
.
HCL OneDB™ ESQL/C
features
These topics explain how the GLS feature affects
HCL OneDB™ ESQL/C
, an SQL application programming interface (API).
