Sql loader:loading data file name to one of the tabe column.

Question

Hi,
I want to load the data file name also to one of the table column.
Table structure:
File_Name varchar2
Name varchar2
Age number
Data File Format:
Vijay|24
Anandh|24
Senthil|26
In the above eg how to write a control file to load the data file name to the File_Name column of the table.
Note:
The shell script will first pick up the data files to be loaded and calls the control file.
Thanks,
Vijay.

Answer 1

From a unix load perspective this is what we have done :
Create a control file (say load_data.ctl) something like
LOAD DATA
append
Into table file_name_age
File_Name constant '<FILENAME>',
Name CHAR TERMINATED BY '|'
Age INTEGER EXTERNAL TERMINATED BY '|' )
in a unix loop do the following
for i in `ls $LOADDIR` ; do
#Replace <FILENAME> with actual filename and create a temp ctl file
sed s/\<FILENAME\>/${1}/g < ${CTLDIR}/load_data.ctl > ${TMPDIR}/load_data_${1}.ctl
#load using temp file
sqlldr / CONTROL=${TMPDIR}/load_data_${1}.ctl
DATA=$i
#remove temp
rm ${TMPDIR}/load_data_${1}.ctl
done
Where
${TMPDIR}=your temp directory
${CTLDIR}=where your main directory for ctl files
$LOADDIR=Your data directory
