The TRUNCATE option of SQLLDR might appear to work differently than TRUNCATE does in SQL*Plus, or any other tool. SQLLDR, working on the assumption you will be reloading the table with a similar amount of data, uses the extended form of TRUNCATE. Specifically, it issues the following: truncate table t reuse storage The REUSE STORAGE option does not release allocated extents it just marks them as free space. If this were not the desired outcome, you would truncate the table prior to executing SQLLDR.

This does not mean the data will not fit into the database column; rather, it indicates that SQLLDR was expecting 255 bytes or less of input data, and it received somewhat more than that. The solution is to simply use CHAR(N) in the control file, where N is big enough to accommodate the largest field length in the input file.

Many of the SQLLDR options may be either placed in the control file or used on the command line. For example, I can use INFILE FILENAME as well as SQLLDR ... DATA=FILENAME. The command line overrides any options in the control file. You cannot count on the options in a control file actually being used, as the person executing SQLLDR can override them.

SQLLDR Summary
In this section, we explored many areas of loading data. We covered the typical, everyday issues we will encounter: loading delimited files, loading fixed-length files, loading a directory full of image files, using functions on input data to transform the input, and so on. We did not cover massive data loads using the direct path loader in any detail; rather, we touched lightly on that subject. Our goal was to answer the questions that arise frequently with the use of SQLLDR and that affect the broadest audience.
External Tables
External tables were first introduced in Oracle9i Release 1. Put simply, they allow us to treat an operating system file as if it is a read-only database table. They are not intended to be a replacement for a real table, or to be used in place of a real table; rather, they are intended to be used as a tool to ease the loading and, in Oracle 10g, unloading of data. When the external tables feature was first unveiled, I often referred to it as the replacement for SQLLDR. This idea still holds true most of the time. Having said this, you might wonder why we just spent so much time looking at SQLLDR. The reason is that SQLLDR has been around for a long time, and there are many, many legacy control files lying around. SQLLDR is still a commonly used tool; it is what many people know and have used. We are still in a period of transition from the use of SQLLDR to external tables, so SQLLDR is still very relevant. What many DBAs don t realize is that their knowledge of SQLLDR control files is very readily transferable to the use of external tables. You ll discover, as we work through the examples in this part of the chapter, that external tables incorporate much of the SQLLDR syntax and many of the SQLLDR techniques. SQLLDR should be chosen over external tables in the following three situations: You have to load data over a network in other words, when the input file is not on the database server itself. One of the restrictions of external tables is that the input file must be accessible on the database server. Multiple users must concurrently work with the same external table processing different input files. You have to work with LOB types. External tables do not support LOBs.
