INSERT INTO `Bans` SET `BanUserName` = '%s',`BanUserIp` = '%s',`BanAdministratorName` = '%s',`BanReason` = '%s',`BanTime` = '%i'


INSERT INTO `Bans`(BanUserName, BanUserIp, BanAdministratorName, BanReason, BanTime) VALUES ('%s', '%s', '%s', '%s', '%d')

This is your query fixed

INSERT INTO bans (time, reason, nickname) VALUES ('%d', '%s', '%s')

This is the correct query if you want to add into "bans" table
( time, reason, nickname ) -> where add values?
( values ) -> values
