Sql loader help needed urgent

Question

Hi,
I normally get a csv having data as
column1 ;columnb;columnc;
13 ; 12 ; 13 ;
11 ;13 ;33;
as the table where it needs to go is say table
xys( a number, b number , c number).
so the control file is fairly simple ...
But from now I need to restrict data entry if the change in format happens in the csv
say if it is like
column2;column1;column3,
12,13;12;
11;13;14;
or say the csv like
column1;column2;column3;column4;
11;13;14;15;
111;134;14;12;
in both cases sql loader should not run and throw the error saying the reason in the log.
how do i manage it in the control file `???
any ideas???
regards

Hello,
do you only need to check the first line of the file if it contains a line like
column1;column2;column3 ?
If yes, maybe a small script like this could be a starting point:
You have to replace "column1;column2;column3" with the header information that's valid and instead of file1 in the CURRENTSTRING=... Line write the name of your input file.
I hope this helps. (But maybe some of the experts here knows a way to do the verification checks with SQLLDR, so maybe its worth to wait a little bit :)
#!/bin/ksh
VALIDSTRING="column1;column2;column3"
CURRENTSTRING=`head -n 1 file1`
if [[ $VALIDSTRING == $CURRENTSTRING ]]
then
echo "They match."
else
echo "They dont match."
fi
