If you're still interested there's another way. Just add '\' where you go to a new line:
pawn Code:
format(query, sizeof(query),
"INSERT INTO playerdata (user, password, score, money, level, vip, kma, rank, kills, deaths, muted, jailed, \
frozen, mutedtimes, jailedtimes, frozentimes, banned, bannedby, logins, cookies, warn1, warn2, warn3, \
warn1reason, warn2reason, warn3reason, dateregisterd, kickedtimes, restorepos, slapedtimes, posx, posy, \
posz, posa, IP) VALUES('%s', SHA1('%s'), 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, '%s', 017, 0, 0, 0, \
0, 'No Warn', 'No Warn', 'No Warn', '%s', 0, 0, 0, 0, 0, 0, 0, '%s')",
pname, passwordstring, Bannedby, ReggedDate, IP);
mysql_query(query);
