"SQL statement" might be a good idea in the first sentence, but
I don't think you need to repeat it in the second.

What's bothering me about this wording is that you're talking about
statements and then suddenly reference transactions (as being "those
other things messing with your data"). This seems weirdly asymmetric,
since after all you could equally well be the one messing with their
data.
