Okay, I'm setting up a transaction with my basic eval block. I'm running through several update and insert statements which, along the way, i must compare the rows affected to other select query information. What I've run into is that my select statements always return 0 rows when using the same database connection yet with a seperate connection, it returns properly. Having recently switched from Oraperl to DBI, I wasn't sure if this was as intended or I'm just doing something wrong...sample code follows:

# Begin the SQL Stuff
eval
{    
    ###############################    
    # Begin stu_drop.updt section #
    ###############################
    
    print "Beginning stu_drop.updt section...\n";
    
    # Open stu_drop.log file
    open(LOG, ">stu_drop.log") or die "Couldn't open log file: $@\n";

    $sql = "UPDATE saturn.sfrstcr SET
                sfrstcr_rsts_code = 'DB',
                sfrstcr_error_flag = 'D',
                sfrstcr_rsts_date = SYSDATE,
                sfrstcr_activity_date = SYSDATE
            WHERE
                sfrstcr_term_code = '$term_code' 
                AND sfrstcr_rsts_code LIKE 'R%'
                AND sfrstcr_pidm IN (SELECT DISTINCT pidm FROM studrop
+)";
    
    $sth = $dbh->prepare($sql);
    $sth->execute();
    $rows_affected = $sth->rows;
    $sth->finish();
    
    print "Rows affected by stu_drop.updt: $rows_affected\n";
    print LOG "$sql\n\nRows affected: $rows_affected\n\n";

    $sql = "SELECT
                count(*) THE_COUNT
            FROM
                sfrstcr,
                spriden
            WHERE
                sfrstcr_term_code='$term_code'
                AND    sfrstcr_pidm in
                (
                    SELECT 
                        pidm    
                    FROM 
                        studrop
                )
                AND sfrstcr_rsts_code like 'R%'
                AND sfrstcr_pidm=spriden_pidm
                AND spriden_change_ind IS NULL
                AND spriden_entity_ind ='P'";
    
    $sth2 = $dbh2->prepare($sql);
    $sth2->execute();
    
    print LOG $sql . "\n";
        
    while(@row = $sth2->fetchrow_array)
    {
        ($row_count) = @row;
        print LOG "Rows pulled from stu_drop_list: $row_count\n";
    }
    
    $sth2->finish();

    if ($row_count == $rows_affected)
    {
            print "No prob with counts\n";
    }
    else
    {
            print "stu_drop_list = $row_count but other = $rows_affect
+ed!\n";
            $dbh->rollback;
            $dbh->disconnect();
            $dbh2->disconnect();
            exit 1;
    }
    
    close(LOG);
