I have a file that contains a list of all the table names that I found when searching through SQL files. I have a file that contains ALL the tables ALONG WITH the database that they belong to as well. What I want to do is compare the file that contains JUST the tables I found in the SQL files to the file that contains the tables ALONG WITH the database. If there is a match, I want to pull the ENTIRE line (database, table) so that I can then upload the file into an excel spreadsheet. The code that I have used to pull the tables from the SQL files is as follows: 
#This will open the file that will contain the list of tables
open(TABLES, '<DBtest.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 parsed
open(DOUT, '<databaseJoinDan.txt') or die "The file databaseJoinDan.tx
+t could no
t be opened\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=<DOUT>;
@tableUsed=<USED>;

#declarations
$Y=0;
$T=0;

#This will search through the files and see if the tables exist in the
+ file

chomp @tableList;
chomp @fileList;
for $Y (@tableList){
        for $T (@fileList){
                if($T =~ /$Y/i){
                print USED "$Y\n";
        }
        }
}#end of the for loop


close(DOUT);
close(TABLES);
close(USED);

-Therefore, after executing this code I have a list of tables but what I REALLY WANT is a the DB along with the table name. The file that contains an ENTIRE listing of all DB names along with their tables is DatabaseTables.txt. I just want to be able to search through that file using the tables that I found in the first search to pull the ENTIRE listing (DB & TABLENAME). Please help if you can.
