I think there is a way to do this, but I am having a hard time finding someone who as already asked this. Basically I have a huge SQL table schema, and I am trying to identify certian table the structure of the file looks like this:

{ TABLE "foo".bar row size = 50 number of columns = 5 index size = 25 
+}
create table "foo".bar 
  (
    var1 char(3) not null constraint "foo".n676_5452,
    var2 char(3) not null constraint "foo".n676_5453,
    var3 date not null constraint "foo".n676_5454,
    _rcd smallint 
        default 0 not null 
  );
revoke all on "foo".bar from "public";

What I want to do is to grab the name of the table (bar) and then look through the table declaration section to determine how many variables there are and which vars are in there. The problem is that I don't think I have the control over the file handle to walk back and forth through the file. This is what I have so far:

$file_name = @ARGV[0];

open (SCHEMA, $file_name);
open (BIGLIST, ">>table_names.txt");
open (SMALLLIST, ">>refined_tbl_name.txt");

#open the file
while(<SCHEMA>) {
    $line = $_;
#is this a line that declares a new table?
    if ($line =~ /create table \".+?\"\.(.+?)$/mos) {
#if so, print the name into a list    
             print BIGLIST "$1 \n";
#create a new variable that has the name
        $table_nm = $1;        
    }
}

At this point, I basically want to say

while ($line ne    ')') {
     $line_cnt++;
     if ($line =~ /$var_of_interest/) {$keep = 1};
}
if ($line_cnt > $n and $keep == 1} then {$table_hash{$table_nm} = 1;}

However, this does not even come close to working very well. Because It can only work if $line is between the two parentheses. Is there a way to look ahead into the file? I can't figure it out, and the camel book is at home. Any pointers would be appreciated.

Thanks a lot.
