you better at the same time install a real database engine, such as MySQL

Of course, MySQL is fine if you don't actually need a real database. But then, you might as well just use DBD::SQLite.

Can't coerce array into hash at C:/Perl/site/lib/DBD/AnyData.pm line 247.

Here is the some of the test code I am using for 1 join:

$dbh = DBI->connect('dbi:AnyData(RaiseError=>1):');

$dbh->func( 'rdbtable', 'ARRAY', @rdb, 'ad_import');
$dbh->func( 'asitable', 'ARRAY', @asi, 'ad_import');
$dbh->func( 'bomtable', 'ARRAY', @bom, 'ad_import');
$dbh->func( 'mpttable', 'ARRAY', @mpt, 'ad_import');

$rdbtable_sth = $dbh->prepare( "SELECT SIGNAL_NAME,LOCATION,X_COORDINA
+TE,Y_COORDINATE,Z_COORDINATE,COMPONENT_SIDE,ETCH_SIDE,GROUND,GROUND_L
+OCATION FROM rdbtable" );
$asitable_sth   = $dbh->prepare( "SELECT SIGNAL_NAME,LOCATION,REFERENC
+E_DESIGNATOR,PIN_NUMBER,DEVICE_NAME,PACKAGE_TYPE,CS_PART_NUMBER FROM 
+asitable WHERE LOCATION = ?" );
$rdbtable_sth->execute;
while (($location,$rdb_signal_name) = $rdbtable_sth->fetchrow_array) {
    $asitable_sth->execute($location);
    $row = $asitable_sth->fetchrow_arrayref;
    $asi_signal_name = $row ? $row->[0] : '';
    print "$rdb_signal_name : $asi_signal_name\n";
}

Here are the 2 tables:

rdbtable:

Any suggestions for fixing what I have or better ways to handle this situation would be greatly appreciated.

Thanks again,

Can't coerce array into hash at C:/Perl/site/lib/DBD/AnyData.pm line 247.

This appears to be caused by the way my array of arrays is created.

I am creating it in the following manner:

$test[0][0] = 'No';
$test[0][1] = 'Letter';
$test[0][2] = 'Roman';
$test[1][0] = 1;
$test[1][1] = 'a';
$test[1][2] = 'i';
$test[2][0] = 2;
$test[2][1] = 'b';
$test[2][2] = 'ii';
$test[3][0] = 3;
$test[3][1] = 'c';
$test[3][2] = 'iii';
$test[4][0] = 4;
$test[4][1] = 'd';
$test[4][2] = 'iv';
$test[5][0] = 5;
$test[5][1] = 'e';
$test[5][2] = 'v';
$test[6][0] = 6;
$test[6][1] = 'f';
$test[6][2] = 'vi';

I don't currently see what the difference is from the following (which works):

@test = [
     ['No','Letter','Roman'],
     [1,'a','i'],
     [2,'b','ii'],
     [3,'c','iii'],
     [4,'d','iv'],
     [5,'e','v'],
     [6,'f','vi']
     ];
