I am using SQLloader to load the text data to into a clob field. It does everything fine except it truncates the begining spaces in
the text data.

Here is my control file.

LOAD DATA
INFILE '/orabase/rls100/migration/lc_final/LOADER/DATA/CORRESP_DATA.dat' "str '\
n'"
INTO TABLE CORRESP_DATA APPEND
REENABLE
TRAILING NULLCOLS
(CORRESP_DATA_ID FLOAT EXTERNAL TERMINATED BY "|"
,CORRESPONDENCE_ID FLOAT EXTERNAL TERMINATED BY "|"
,CORRESP_ELEMENT_NO FLOAT EXTERNAL TERMINATED BY "|"
,TEXT CHAR(4000) TERMINATED BY "|" OPTIONALLY ENCLOSED BY '"'
)

TEXT field is defined as CHAR(4000) in the control file where as the database the field is defined as CLOB.

Here is the sample TEXT field data of the unload record.

12594377|8829361|240| XXXXXXXXX $.00 XXXXXXXXX 0 4.8750% $.00 $.00 $.00 $.00 $.00 0 0.0000% $.00 $.00 $.00 $.00 57120 9.9999% $99.99 $99.99 YYYYYYY ZZZZZZZZZZ |

Please note there are 3 spaces in the above record before the XXX

RESULT : - After Load the data looks like this.

there are no spaces before XXXX.....

12594377|8829361|240|XXXXXXXXX $.00 XXXXXXXXX 0 4.8750% $.00 $.00 $.00 $.00 $.00 0 0.0000% $.00 $.00 $.00 $.00 57120 9.9999% $99.99 $99.99 YYYYYYY ZZZZZZZZZZ |

I need the data should be as is after the load.
Can someone shed some light as to what should I do.

Thanks much.

Remove the part that says:

OPTIONALLY ENCLOSED BY '"'

Thanks Barbara. It worked.

However I had to change the datatype in table to VARCHAR2 before loading it. Then changing to CLOB datatype.

Got question on this.
Is it possible to change the datatype of a field from VARCHAR2(4000) to CLOB without losing the data in a table?
What is the syntax for it.

Thanks in advance
