Several methods are available for loading data into tables in an Oracle database. Of the methods available Direct-Load insert and SQL*Loader are discussed here.
SQL*Loader loads data from external files into tables of an Oracle database. It has a powerful data parsing engine that puts little limitation on the format of the data in the datafile.
Direct-load insert can be used to copy data from one table to another table within the same database.
Data Loading Methods
Several methods are available for loading data into tables in an Oracle database. Of the methods available, Direct Load insert and SQL*Loader are discussed here. Export and Import are covered in the Oracle9i Database Administration Fundamentals II course.
SQL*Loader loads data from external files into tables of an Oracle database. It has a powerful data parsing engine that places little limitation on the format of the data in the data file.
Direct Load insert can be used to copy data from one table to another table within the same database.
[ Team LiB ] Recipe 2.1 Retrieving Hierarchical Data into a DataSet Problem You want to fill a DataSet with parent and related child data, even if the DataSet already has a schema that includes the relationship. Solution There are several techniques you can use to load parent and child data into a DataSet.
Oracle Database Utilities is intended for database administrators (DBAs), application
programmers, security administrators, system operators, and other Oracle users
who perform the following tasks:
- Archive data, back up an Oracle database, or move data between Oracle
databases using the Export and Import utilities (both the original versions and
the Data Pump versions)
- Load data into Oracle tables from operating system files using SQL*Loader or
from external sources using the external tables feature
- Perform a physical data structure integrity check on an offline database, usin...
[ Team LiB ] Recipe 2.20 Retrieving Data from an Oracle Package Problem Given an Oracle package that returns multiple result sets for related tables as REF CURSOR data types, you want to access this data using a DataReader and load the data into a DataSet. Solution Use the data type OracleType.Cursor .
This book will walk you through the complete process of planning, building, and deploying a data warehouse using Oracle Warehouse Builder. By the book’s end, you will have built your own data warehouse from scratch.
Starting with the installation of the Oracle Database and Warehouse Builder software, this book then covers the analysis of source data, designing a data warehouse, and extracting, transforming, and loading data from the source system into the data warehouse.
Significant trends in analytics and information management, along with regulatory pressures, demand new technologies
that can turn increasing volumes of data into insight that can be exploited very rapidly. In addition, customer dynamics are
changing more frequently so the need to develop and refresh analytic models that can be managed securely is
When you create a geodatabase, as you did in Exercise Add a database
server to the Catalog tree and create a geodatabase, there is no data in it.
You must add data to new geodatabases either by creating new datasets,
importing data, or copying data from one geodatabase and pasting it into
In this exercise, you will create a feature dataset, then import data from a
personal geodatabase to populate it. You will also copy data from a file
geodatabase and paste it into your new geodatabase. After the data is
loaded, you will update the database statistics....
You must load your data warehouse regularly so that it can serve its purpose of
facilitating business analysis. To do this, data from one or more operational systems
must be extracted and copied into the warehouse. The process of extracting data from
source systems and bringing it into the data warehouse is commonly called ETL,
which stands for extraction, transformation, and loading.
A materialized view provides access to table data by storing the results of a query in a
separate schema object.
The Luxicon Pro CD-ROM contains luminaire data (called a Plugin) for all Cooper Crouse-Hinds products..
After you install the DIALux program, you need to install the complete luminaire database tree for the Cooper Crouse-Hinds Plugin by clicking on the Luminaire tab and then double clicking on the Cooper Crouse-Hinds logo on the left side of your screen.. The program will then load the complete Cooper Crouse-Hinds database into your project (see Figure 1).
