What is "%e" standing in your query?

So I took little search on internet, and look what I found about %e.

Код:

%e prints the number in scientific notation, e.g. 3.2165e+2.

It`s in C language. I guess that you want to load string from your query, so make it %s instead of using %e.

PlayerName is string.
IP is string.

Second thing If I would be you, I would use this kind of query:

PHP код:

"SELECT * FROM `bans` WHERE `IP` = '%s' LIMIT 1"
