I'm trying to compare two lists. I have read in two files and stored them as lists. one files contains a list of DB table names while another file contains a list of SQL statements. What I want to do is compare the two. If the list of DB table names match anything in the SQL file, I want to print the table name that was matched. This is the code I have written but doesn't work.

#----------------------------------------------------

#This section will contain the searched for the DB tables in the SQL f
+iles
#and return all lines that contain an instance of a DB table.


#This will open the file that will contain the list of tables
open(TABLES, '<DBtables1.txt') or die "The file DBnames.txt could not 
+be opened\
n";

#This will open the file that will contain the list of SQL statements 
+to be pars
ed
open(UPDATE, '<updateDan.txt') or die "The file updateDan.txt could no
+t be opene
d\n";

#This will open the file that will be written to containing the list o
+f tables
#in the SQL files

open(USED, '>>tableUsed.txt') or die "The file tablesUsed.txt could no
+t be writt
en to\n";

#This will convert the files into lists to be searched
@tableList=<TABLES>;
@fileList=<UPDATE>;
@tableUsed=<USED>;

#declarations
$W=0;
$Q=0;

#This will search through the files and see if the tables exist in the
+ file
foreach $W (@tableList)
{
        foreach $Q (@fileList)
        {
                #if (exists($Q{$W}))
                if($W==$Q)
                {
                        #print TABLE "$W\n";
                        push(@tableUsed, $W);
                        print USED @tableUsed;

                }#end of if
                else
                {
                        print USED "no tables exist in the file\n";
                }
        }
}#end of foreach loop


close(UPDATE);
close(TABLES);
close(USED);

#----------------------------------------------- I have tried several solutions as you can see with the commented lines that were once statements. Please if you know of a way I can do this, it will tremendously help me with my project. I am new to PERL and therefore am just beginning to learn the syntax and its capabilities. Thanks
