I installed DBD::mysql 4.018 and DBI 1.616 and ran the following based on your posting (note I had to invent $planname and substitute $dbname. Also I took out the fetch as it cannot work:

use strict; use DBI; my $h = DBI->connect('dbi:mysql:database=test', "xxx", "yyy"); eval { $h->do(q/drop table CUSTOMER_PLAN/); }; $h->do(<<EOT); CREATE TABLE `CUSTOMER_PLAN` ( `RowId` int(11) unsigned NOT NULL auto_increment, `Name` varchar(6) default NULL, `Credits` smallint(6) unsigned default NULL, `Price` decimal(8,2) default NULL, `Credit_Value` decimal(3,2) default NULL, `Status` char(1) default NULL, # A=Active, I=Inactive `Display_Order` char(3) default NULL, `Description` varchar(255) default NULL, PRIMARY KEY (RowId), KEY planname (Name), KEY descript (Description(15)), KEY dispord (Display_Order) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; EOT $h->do(q/INSERT INTO `CUSTOMER_PLAN` VALUES(1, 'Free', 0, 0.00, 0 +.75, 'A', '001', 'Try us out - receive 3 free recipes.')/); $h->do(q/INSERT INTO `CUSTOMER_PLAN` VALUES(2, 'Shine', 12, 9.75, 0 +.75, 'A', '002', 'Shine with a small introduction to Vibrant Healthy +Living.')/); $h->do(q|INSERT INTO `CUSTOMER_PLAN` VALUES(3, 'Seeker', 35, 18.75, 0 +.75, 'A', '003', '<i>-noun.</i> An adventurous person who is seeking +new experiences and new information to create a higher level of under +standing and enlightenment.')|); $h->do(q|INSERT INTO `CUSTOMER_PLAN` VALUES(4, 'Sage', 60, 47.00, 0 +.75, 'A', '004', '<i>-noun.</i> A generous, lively person on the jour +ney for the possession of wisdom and experience. This person is energ +etic, vibrant and famed for health and wisdom.')|); $h->do(q|INSERT INTO `CUSTOMER_PLAN` VALUES(5, 'Guru', 120, 89.00, 0 +.75, 'A', '005', '<i>-noun.</i> A divine teacher. This person has vas +t knowledge and practices vibrant living while sharing with their com +munity to create a greater understanding and manifestation of truth a +nd beauty.')|); sub db_err { my ($pmsg, $psql, $perrnum, $perrstr) = @_; print "<p>There was a problem: $pmsg.</p>\n"; print "<p><i>Attempted command:</i> $psql</p>\n"; print "<p><i>Error:</i> $perrnum - $perrstr</p>\n"; } my $dbname = 'test'; my $planname = 'Free'; my $sql = "SELECT DCredits, Price, Description FROM $dbname.CUSTOMER_P +LAN WHERE Name='$planname'"; my $sqlh = $h->prepare($sql) || db_err("preparing statement handle", $ +sql, $DBI::err, $DBI::errstr); $sqlh->execute || db_err("executing query", $sql, $DBI::err, $DBI::err +str); #####while (@row = $sqlh->fetchrow_array()) #####{ ##### ($credits, $price, $descript) = @row; ##### # process the data on each loop here #####} #####$sqlh->finish; $h->disconnect;

It fails with:

DBD::mysql::st execute failed: Unknown column 'DCredits' in 'field lis +t' at /home/martin/930402.pl line 45. <p>There was a problem: executing query.</p> <p><i>Attempted command:</i> SELECT DCredits, Price, Description FROM +test.CUSTOMER_PLAN WHERE Name='Free'</p> <p><i>Error:</i> 1054 - Unknown column 'DCredits' in 'field list'</p>

When I rerun it with DBI_TRACE=15 I get the following near the end:

What does your trace output look like on the failing machine?
