Hi Guys, I have a plain text file with a sql statement and want to put a variable name within it, which should be read by my perl script.

So for example: There is a a file called input.txt with the SQL content as below. Notice the $table_name intended to be processed within the script.

input.txt Text File content :
 select * from all_tables where table_name = '$table_name'
Perl Script readSQL.pl:
my $sql;
my $table_name = "EMPLOYEE"; # setting a table name. 
my $Inputfile = 'input.txt';
    open my $filecontent, $inputfile or die "Could not open $inputfile
+: $!";

        while( my $readline = <$filecontent>)  
        {   
            print "$line \n";    
            $sql = $readline;
            executeSQL();

        }
    close $$filecontent;
}

If I execute the script, it reads the file but treats the $table_name as a string. How can I tell perl to treat it as a variable and assign the $table_name value declared at the start of the script to this value?

Thanks for any inputs on this..
