Make sure to close your tmp file before starting the loader. This will flush all data to the file.

We have a winner!

THANK YOU THANK YOU THANK YOU

Closing the files made it work. Thats one of those detail things that I can be lazy about and it finally bit me in the butt.

Thank you again,

That's what i thought. See my previous post below (very end). I did not do a re:re:re

Disclaimer: Whatever errors I find may be unrelated to the problem itself as I repeatedly got distracted while writing this comment...

- (A trait of senior monks that's rubbed off on me): use strict - it helps...

- Shouldn't


for ($ii = @time[0]; $ii <= @time[$#time]; $ii++)

be using $time[0] and $time[$#time]? There are also other lines using that notation...

- In your "Code with DBI" make PrintError=>1 and redirect the output for late night reading ;)

- Check those output files to make sure that there are no "character combinations" that have a special meaning in SQL... It could be where you're losing the data...
