Hello guys!How can i use the variables bannedBy, and accountID outside of this code block?

local accountID
for _, row in ipairs(query)
	 local bannedBy = row["bannedBy"]
	local accountID = row["accountID"]
end

If you remove the "local" inside the loop, they will be available outside of the loop, because you defined them outside of the loop too.

But since this is a loop, the two variables will only have the value of the last row, everything before that is lost.

only the last row? How u think that?

What @Bonsai recommended was removing 'local' on both lines within the loop. And he is right about the last row thing. What the code will do if you remove the 'local' is change the same variables over and over again, and what will be on these variables after the last loop, is what was set on the last iteration: the data from the last row of the query table.
