Is there any risk in using sp_detach in production database? I would like to move some of my data file in different array partition to have more disk space. I'm just worried about the uncommitted transaction in my production database.

If i have a downtime schedule let say tomorrow at 8:00 am then i detach my database at 8:30 am. What will happen to the transactions? Is the sp_detach will not delete the uncomitted transcation then this will comit after sp_attach? i know the transaction is in logs, I just want to make sure that i will not do anything wrong in my data.

Thanks for the expert advice.
