I'm not aware of any German term that clearly differentiates zero and NULL.
Since in software development English is a big influence, it's quite common to use English terms directly, without translating them: "NULL" (pronounced like the english word) in a German sentence would clearly refer to NULL as opposed to zero. Fortunately the German word "null" (for zero) is pronounced quite a bit differently.
If any confusion is possible, then you can even use the English word "zero" to refer to 0 or rephrase the sentence to avoid any reference to zero or null: "Es wurden keine Zeilen zurückgegeben."

I am a software developer, so I think I can say something about that. At least in the companies I worked for, we used the English word NULL for NULL and the German word Null (Zero) for the number zero. So NULL is just a technical term for us and we don't translate a lot of them.
I work in IT, and I am stumped in how to clearly separate between ''null'/null' and '0'/'null when speaking with germans. When speaking "zero", to remove any doubt, I am usually given a weird look, specially because I am a beginner with German.. Any advice on context, or even Intonation, to make this smoother?

It’s an important concept in Computer Science. If you still don’t get the difference, a zero has a value (which is zero) but null has no value at all. Like the difference between seeing black and being blind.
