Designing databasesThe 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.
Designing and Implementing a DatabaseThe HCL OneDB™ Database Design and Implementation Guide provides information to help you design, implement, and manage your HCL® OneDB® databases. It includes data models that illustrate different approaches to database design and shows you how to use structured query language (SQL) to implement and manage your databases.

provides functions that you can call from within an SQL statement to import and export smart large objects. The following table shows the smart-large-object functions.

Table 1. SQL functions for smart large objects
Function Name	Purpose

FILETOCLOB()	Copies a file into a CLOB column
LOCOPY()	Copies BLOB or CLOB data into another BLOB or CLOB column
LOTOFILE()	Copies BLOB or CLOB data into a file

For detailed information and the syntax of smart-large-object functions, see the Expression segment in the HCL OneDB™ Guide to SQL: Syntax.

Restriction: Casts between BLOB and CLOB data types are not permitted.
