Oracle9i Database Utilities Release 1 (9.0.1) Part Number A90192-01 |
|
This document describes how to use the Oracle9i database utilities for data transfer, data maintenance, and database administration.
This preface contains these topics:
This document is for database administrators (DBAs), application programmers, security administrators, system operators, and other Oracle users who perform the following tasks:
To use this manual, you need a working knowledge of SQL and Oracle fundamentals, information that is contained in Oracle9i Database Concepts. In addition, SQL*Loader requires that you know how to use the file management facilities of your operating system.
This document contains:
This chapter describes how to use Export to write data from an Oracle database into transportable files. It discusses export guidelines, export modes, interactive and command-line methods, parameter specifications, and Export object support. It also provides example Export sessions.
This chapter describes how to use Import to read data from Export files into an Oracle database. It discusses import guidelines, interactive and command-line methods, parameter specifications, and Import object support. It also provides several examples of Import sessions.
This chapter introduces SQL*Loader and describes its features. It also introduces data loading concepts (including object support). It discusses input to SQL*Loader, database preparation, and output from SQL*Loader.
This chapter describes the command-line syntax used by SQL*Loader. It discusses command-line arguments, suppressing SQL*Loader messages, sizing the bind array, and more.
This chapter describes the control file syntax you use to configure SQL*Loader and to describe to SQL*Loader how to map your data to Oracle format. It provides detailed syntax diagrams and information about specifying datafiles, tables and columns, the location of data, the type and format of data to be loaded, and more.
This chapter describes the field list section of a SQL*Loader control file. The field list provides information about fields being loaded, such as position, datatype, conditions, and delimiters.
This chapter describes how to load column objects in various formats. It also discusses how to load object tables, REF
columns, LOB
s, and collections.
This chapter describes the information contained in SQL*Loader log file output.
This chapter describes the differences between a conventional path load and a direct path load. A direct path load is a high performance option that significantly reduces the time required to load large quantities of data.
This chapter presents case studies that illustrate some of the features of SQL*Loader. It demonstrates the loading of variable-length data, fixed-format records, a free-format file, multiple physical records as one logical record, multiple tables, direct path loads, and loading objects, collections, and REF
columns.
This chapter describes basic concepts about external tables.
This chapter describes the access parameters used to interface with the external tables API.
This chapter describes how to use the offline database verification utility, DBVERIFY.
This appendix provides diagrams of the SQL*Loader syntax.
This appendix describes differences between the data definition language syntax of SQL*Loader and DB2 Load Utility control files. It discusses SQL*Loader extensions to the DB2 Load Utility, the DB2 RESUME option, options included for compatibility, and SQL*Loader restrictions.

The Oracle9i documentation set, especially:
Many books in the documentation set use the sample schemas of the seed database, which is installed by default when you install the Oracle database server. Refer to Oracle9i Sample Schemas for information on how these schemas were created and how you can use them.

This section describes the conventions used in the text and code examples of this documentation set. It describes:
We use various conventions in text to help you more quickly identify special terms. The following table describes those conventions and provides examples of their use.
Code examples illustrate SQL, PL/SQL, SQL*Plus, or other command-line statements. They are displayed in a monospace (fixed-width) font and separated from normal text as shown in this example:
SELECT username FROM dba_users WHERE username = 'MIGRATE';
The following table describes typographic conventions used in code examples and provides examples of their use.
Sample commands, statements, and code examples provided in this manual are specific to the UNIX operating system unless otherwise noted. For information on how to implement the commands and examples on other operating systems, see your Oracle operating system-specific documentation.
Oracle's goal is to make our products, services, and supporting documentation accessible to the disabled community with good usability. To that end, our documentation includes features that make information available to users of assistive technology. This documentation is available in HTML format, and contains markup to facilitate access by the disabled community. Standards will continue to evolve over time, and Oracle is actively engaged with other market-leading technology vendors to address technical obstacles so that our documentation can be accessible to all of our customers.
