Hi All,

My requirement is, I have a fixed width format file with UTF8 format, total length of each record is 113 characters + 1 character for the carriage return. Some of the fields in the data file have multibyte characters (eg: ЛЕРЬЕВИЧAB).
There are 5 fields in the file as follows

Field        -----                     Position
-----------------------------------------------------------
ID	             :               1-10
BLCKG_ID             :               11-12
GENDER               :               13-13 
FIRST_NAME           :               14-63
MIDDLE_NAME          :               64-113 

Using the following create table statement I created an external table:

[code][/code]create table et_test  (
			ID CHAR(10),
			BLCKG_ID CHAR(2),
			GENDER CHAR(1),
			FIRST_NAME CHAR(50),
			MIDDLE_NAME CHAR(50)  
		      )
ORGANIZATION EXTERNAL (
			type oracle_loader
			default directory DATA_DIR
			access parameters    (  RECORDS FIXED 114
						FIELDS	(
			  				 ID (1:10),
							 BLCKG_ID (11:12),
							 GENDER (13:13),
							 FIRST_NAME (14:63),
							 MIDDLE_NAME (64:113)
							)
					     )
			location ('Testing.txt')
		     )



When I try to retrieve the data from External table, for the first record in the file everything is fine but for the remaining records the value of ID, BLCKG_ID and Gender appear in the First_Name column, First_Name in Middle_Name column and Middle_Name is not available.

When I load the same file using SQL Loader script it works fine but with external table I'm facing the problem.


Can anybody please help me in this regard and let me know if there is something that I'm missing.


Thanks,
MSAM

Did you try:

 RECORDS FIXED 114
?

Yes, if you see the query I have posted for external table creation, in the access parameter I have specified
RECORDS FIXED 114.

Is there something wrong with that?
Thanks,
MSAM

Hi Michael,

Some more information related to the query.

The format of my input file is fixed width, UTF8 and Line Terminator is "Unix Terminator-LF".

I made some changes to the extrenal table defination, I added "CHARACTERSET UTF8" to the access parameter list.

But still the same problem persists.

Following is some sample data from the input file
1 011MАНДРЕЙ ВАЛЕРЬЕВИЧ
2 020MАНДРЕЙ ВАЛЕРЬЕВИЧ


Please help me to solve this problem.


Thanks & Regards,
MSAM

I tried with 113 as well, but no change in the result.

It looks like you have a problem with your data:
1. There is a prefix of 3 bytes in the first line of the datafile you attached.
2. The record length is variable ( 131-129 bytes).
