Use this SQL :
INSERT INTO `npc` VALUES ('555', '36562', 'Buffer', '1', 'Buffer', '1', 'LineageNPC2.garrison_of_insurgents', '10.00', '23.75', '86', 'male', 'L2Npc', '40', '32490.000000000000000', '1712.000000000000000', '56.000000000000000', '3.000000000000000', '40', '43', '30', '21', '20', '20', '0', '0', '200.00000', '300.00000', '300.00000', '300.00000', '230', '1', '0', '333', '0', '0', '0', '60.00000', '120.00000', '1', '1', '0', '1');
