hello

I'm having an issue with insertions/updates using DBI. With Blokhead's help (sorry for getting snippy, Blokhead, but I do try to look things up before I ask) I turned up tracing and I'm not understanding what I'm seeing.

This is the table:

| Field   | Type         | Null | Key | Default
+---------+--------------+------+-----+------------------
| tstamp  | timestamp    | YES  | PRI | CURRENT_TIMESTAMP
| url     | varchar(64)  |      | PRI |
| average | double(17,1) | YES  |     | NULL
| maximum | bigint(20)   | YES  |     | NULL
| total   | double(17,0) | YES  |     | NULL

Here is the code in question

foreach $key (sort keys %urls)
{
  my @tmpData = @{$urls{$key}};
print "\nDATA: @tmpData\n";
  eval
  {
    $i2_stmt->execute(@tmpData[0],@tmpData[1],@tmpData[2],@tmpData[3],
+@tmpData[4
]);
  };
  if ($@)
  {
    $u2_stmt->execute(@tmpData[2],@tmpData[4],@tmpData[4],@tmpData[3],
+@tmpData[4],@tmpData[0],@tmpData[1]);
  }
}

the general idea is to insert incoming data, but if a row already exists, update it instead. For test data I'm loading the same data twice, so in the trace output I should be seeing a nice flow of insert, fail, update, insert, fail, update... but I'm seeing insert, fail, update, insert, insert, insert, fail update, fail, exit.

The DATA lines are a print line of the input data. I'm also seeing fresh lines being inserted with current time... which might indicate I'm seeing null timestaps... but I don't see that in the DATA lines or the binds to the update

thanks
