Re: SQL from shell script

You want to delete these entries, I assume?

Yes, I want to delete the entries.

You could write a simple perl script that looks like:

#!/usr/bin/perl
use strict;
my $date = shift; #get from command line

my @tables = (qw/ table1 table2 table3 /); #put in your tablenames here
foreach my $tablename (@tables) {
print "create table temp1 as select * from $tablename where
date='$date';\n";
print "COPY temp1 TO '$tablename.$date.txt';\n";
print "DROP table temp1;\n";
print "DELETE FROM $tablename WHERE date='$date';\n";
}

This is kind of what I want to do. The only problem here is that first statement where I create temporary tables, will be selecting data from different tables based on different where clauses. Some of them even use join on tables. So I guess I can't use the foreach statement.

Thanks a lot for the help, this definitely has given me a lead on how to proceed.

Thank you very much,
