Oracle® SQL Loader files are text files formatted for loading into relational databases. In particular, the format of these files works well with the SQL Loader utility supplied by Oracle for use with Oracle databases.
For more information, see the Column-Aligned Text (CAT) Reader.
Notes about the Oracle SQL Loader Format
This type of file can only be written – it is not possible to read these files.
The Oracle SQL Loader writer does not support spatial data, and it does not create the required table when the ctl file is run.
