Office in Virginia| 40,Finance,Virginia,This is the Finance Office in Virginia| [tkyte@desktop tkyte]$ where each record in the data file ends with a |\n, the previous control file will load it correctly. Embedded Newlines Summary We explored at least four ways to load data with embedded newlines in this section. In the upcoming section titled Flat File Unload, we will use one of these techniques, the STR attribute, in a generic unload utility to avoid issues with regard to newlines in text. Additionally, one thing to be very aware of and I ve mentioned it previously a couple of times is that on Windows (all flavors), text files may end in \r\n (ASCII 13 + ASCII 10, carriage return/linefeed). Your control file will have to accommodate this: that \r is part of the record. The byte counts in the FIX and VAR, and the string used with STR must accommodate this. For example, if you took any of the previous .dat files that currently contain just \n in them and FTP-ed them to Windows using an ASCII transfer (the default), every \n would turn into \r\n. The same control file that just worked in UNIX would not be able to load the data anymore. This is something you must be aware of and take into consideration when setting up the control file.

We will now consider some methods for loading into LOBs. This is not a LONG or LONG RAW field, but rather the preferred datatypes of BLOB and CLOB. These datatypes were introduced in Oracle 8.0 and later, and they support a much richer interface/set of functionality than the legacy LONG and LONG RAW types, as discussed in 12. We will investigate two methods for loading these fields: SQLLDR and PL/SQL. Others exist, such as Java streams, Pro*C, and OCI. We will begin working with the PL/SQL method of loading LOBs, and then we ll look at using SQLLDR to load them as well. Loading a LOB via PL/SQL The DBMS_LOB package has entry points called LoadFromFile, LoadBLOBFromFile, and LoadCLOBFromFile. These procedures allow us to use a BFILE (which can be used to read operating system files) to populate a BLOB or CLOB in the database. There is not a significant difference between the LoadFromFile and LoadBLOBFromFile routines, other than the latter returns OUT parameters that indicate how far into the BLOB column we have loaded data. The LoadCLOBFromFile routine, however, provides a significant feature: character set conversion. If you recall, in 12 we discussed some of the National Language Support (NLS) features of the Oracle database and the importance of character sets. LoadCLOBFromFile allows us to tell the database that the file it is about to load is in a character set different from the one the database is using, and that it should perform the required character set conversion. For example, you may have a UTF8-compatible database, but the files received to be loaded are encoded in the WE8ISO8859P1 character set, or vice versa. This function allows you to successfully load these files.

To use these procedures, we will need to create a DIRECTORY object in the database. This object will allow us to create BFILES (and open them) that point to a file existing on the file system that the database server has access to. This last phrase, that the database server has access to, is a key point when using PL/SQL to load LOBs. The DBMS_LOB package executes entirely in the server. It can see only the file systems the server can see. It cannot, in particular, see your local file system if you are accessing Oracle over the network. So we need to begin by creating a DIRECTORY object in the database. This is a straightforward process. We will create two directories for this example (note that these examples are executed in a UNIX environment; you will use the syntax for referring to directories that is appropriate for your operating system): ops$tkyte@ORA10G> create or replace directory dir1 Directory created. as '/tmp/';
