SQL programmingYou can use the HCL OneDB™ implementation of the SQL language to develop applications for HCL OneDB™ database servers.
Guide to SQL: ReferenceThe HCL OneDB™ Guide to SQL: Reference contains the reference information for the system catalog tables, data types, and environment variables of the HCL OneDB™ dialect of the SQL language, as implemented in HCL OneDB™. These topics also include information about the stores_demo, sales_demo, and superstore_demo databases that are included with HCL OneDB™.
Data typesEvery column in a table in a database is assigned a data type. The data type precisely defines the kinds of values that you can store in that column.
Description of Data Types
CLOB data typeThe CLOB data type stores any kind of text data in random-access chunks, called sbspaces. Text data can include text-formatting information, if this information is also textual, such as PostScript™, Hypertext Markup Language (HTML), Standard Graphic Markup Language (SGML), or Extensible Markup Language (XML) data.
Multibyte characters with CLOB

Multibyte characters with CLOB

About this task

You can insert data into CLOB columns in the following ways:

With the dbload utility
With the LOAD statement (DB-Access)
From CLOB (ifx_lo_t) host variables (ESQL/C)

For examples of CLOB types, see the HCL OneDB™ Guide to SQL: Tutorial and the HCL OneDB Database Design and Implementation Guide.

With GLS, the following rules apply:

Multibyte CLOB characters must be defined in the database locale.
The CLOB data type is collated in code-set order.
The database server handles code-set conversions for CLOB data.

For more information about database locales, collation order, and code-set conversion, see the HCL OneDB GLS User's Guide.
