hi

i'll go right to the point. my code is this:


use DBI;
...


$self->connectdb(connection => "./db/nr1.db");
$self->createtable(table => $joinTable,
                   form => $form1);
                          
my $insert = "insert into GITAXNR(gi,ID,quest) select GITAX.gi, GITAX.
+ID, NRP.quest from GITAX inner join NRP on GITAX.gi = NRP.gi";
$self->do_it(argument => $insert);

up tu here everything is going fine, it connects to the database nr1.db , creates a table GITAXNR(gi,ID,quest), inserts into it all queried valeus ... ta, ta, ta,... 
 
   
    for(my $j = 1; $j<=4; $j++){

        unless($j == 1){ 
            
        my $database = "attach database './db/nr$j.db' as nrdb$j";
        $self->do_it(argument => $database);

        my $insert = "insert into GITAXNR(gi,ID,quest) select GITAX.gi
+, GITAX.ID, NRP.quest from GITAX inner join nr$j.NRP on GITAX.gi = NR
+P.gi";
          $self->do_it(argument => $insert);

}
}

here the problems start. when i use just the sqlite engine and attach databases the query : 
insert into GITAXNR(gi,ID,quest) select GITAX.gi, GITAX.ID, NRP.quest 
+from nr1.GITAX inner join nr2.NRP on GITAX.gi = NRP.gi

works perfectly. but when i incorporate it into the code it complains that there is no nr$j (nr2) database (DBD::SQLite::db prepare failed: no such table: nr2.NRP(1) at dbdimp.c line 271 a t Lib/NRDB/NrDBI.pm line 70, <NRLOG> line 15.)

so the problem is obviously in attaching or querying the attached databases. so if anyone has an idea on how to do this...

i looked through SQLite module and i couldn't find anything useful

suggestions ... ?

thank you !
