Hi everybody,

Im having a problem while loading a table with SQL Loader because of multibyte chars.

My table is:
CREATE TABLE TEST_UMLAUT 
(COL1	VARCHAR2(99 CHAR),
COL2	VARCHAR2(3 CHAR),
COL3	VARCHAR2(3 CHAR),
COL4	VARCHAR2(3 CHAR),
COL5	VARCHAR2(7 CHAR),
COL6	VARCHAR2(200 CHAR)
);

My controlfile is:
LOAD DATA 
CHARACTERSET AL32UTF8
INFILE '$FICHIER' BADFILE '$BAD'
APPEND
PRESERVE BLANKS
INTO TABLE TEST_UMLAUT
(
COL1 POSITION(1:99) CHAR,
COL2 POSITION(100:102) CHAR,
COL3 POSITION(103:105) CHAR,
COL4 POSITION(106:108) CHAR,
COL5 POSITION(109:115) CHAR
)

And my data line (7 spaces after the last I) is:
AAAAÖABCDEFGHIÖJKLMNABCDEFGHI

My result should be:
COL1=AAAAÖABCDEFGHIÖJKLMN
COL2=ABC
COL3=DEF
COL4=GHI
COL5= (7 spaces)

But i get:
COL1=AAAAÖABCDEFGHIÖJKL
COL2=MNA
COL3=BCD
COL4=EFG
COL5=HI (with 5 spaces at the end).

Can someone help me to get expected result?

Regards
Yiel

POSITION indicates the position in BYTES and can't be used in your case with your character set.
Use an external table (or a stage table) with a single column and then load the target table from it using SUBSTR.

I suspect that you will have the same problem as the technology is the same. Let us know how you get on!

Not if the external/stage table has a single column and SUBSTR on it is used to fill the target columns as suggested.

Thanks for the help guys,

I used finally a stage table with 1 column and it works fine, but the client didnt want to change all the flows we have (10 flows with more than 200 columns each) so finally the client accepted to convert the source file with sed so we wont find multibyte chars in the final flat file.

Yiel
