UNIX and Linux Applications

Hi all,

I get data-files which has a particular identified on the 1st record( header ), based on which I've to load a constant for the 1st column of every row. How do I set in the control file using unix shell script.

Appreciate if someone can give me some directions on this.


Thanks in advance

What have you done to attempt to solve this problem yourself?

Post your sample script, and we'll see how we can assist.

Hi,

I tried with the shell script but it is not loading into table for the below script

#!/bin/bash

#export custno=""

custno=$(awk -F"," '{print NR " " $3}' 'datafile.txt' | grep 1 | cut -d" " -f2)
sed 's/#x#/'$custno'/g' 'ctrl.ctl'

Below is the data file(datafile.txt)

sno,sNAME,35642,reactflag
1,KIRAN,KUMAR
2,SURESH,KUMAR
3,MADHU,VARIGONDA

Here is the control file(ctrl.ctl)
options(skip =1)
LOAD DATA
INFILE 'datafile.txt'
TRUNCATE INTO TABLE LOADER_TEST
FIELDS TERMINATED BY ','
TRAILING NULLCOLS (
sno Integer external,
sname char(50),
custno char(50) CONSTANT '#x#',
reactflag char(50)
)

Please help me in advance

What is the error are you getting?
Not a good way...

Code:

custno=`head -1 'datafile.txt'  | cut -d"," -f3`

was sufficient.
