Learn how you can use the SQL*Loader control file to specify how data files are loaded. To direct SQL*Loader to access the data files as comma-separated-values format files, use the CSV clause. Specify the BEGINDATA statement before the first data record.

SQL*Loader allows you to load data from an external file into a table in the database. It can parse many delimited file formats such as CSV, tab-delimited, and pipe-delimited.

When configuring SQL*Loader, you can specify an operating system-dependent file processing options string (os_file_proc_clause) in the control file to specify file format and buffering.

SQL*Loader takes data file, as well as a control file, to insert data into the table. When a Control file is executed, it can create Three (3) files called log file, bad file or reject file, discard file. Log file tells you the state of the tables and indexes and the number of logical records already read from the input datafile.

The SQL*Loader control file is a text file that contains data definition language (DDL) instructions for a SQL*Loader job.

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 data files, tables and columns, the location of data, the type and format of data to be loaded, and more. SQL*Loader Field List Reference.

The SQL*Loader control file is a text file that contains data definition language (DDL) instructions. DDL is used to control the following aspects of a SQL*Loader session:

Nov 4, 2022 · Control files, contain a number of commands and clauses describing the data that SQL*Loader is reading. Control files also tell SQL*Loader where to store that data, and they can define validation expressions for the data. Understanding control file syntax is crucial to using SQL*Loader effectively.

A control file controls the behavior of SQL*Loader and one or more data files used in the load. Using a control file gives you more control over the load operation, which might be desirable for more complicated load situations.

This chapter describes the SQL*Loader data definition language (DDL) used to map data to Oracle format. If you are using Trusted Oracle, see also the Trusted Oracle documentation for information about using the SQL*Loader in that environment. …
