The error simply means that you aren't processing the results from your request(s) correctly.

The basic loop should look like this:

$dbproc->dbcmd($the_sql_cmd);
# possibly add more commands to the SQL buffer with additional
# dbcmd() calls

# Send the command(s) to the server
$dbproc->dbsqlexec;

# Process all the results
while($dbproc->dbresults != NO_MORE_RESULTS) {
    # Process any rows that might be returned:
    while(@data = $dbproc->dbnextrow) {
          ..... # do something with the data
    }
}

What you need to realize is that for each INSERT, UPDATE, etc. in your SQL buffer you must call dbresults() at least once - hence the loop until dbresults() returns NO_MORE_RESULTS.
