missing PARTITION or SUBPARTITION keyword

修改Oracle表时报这个错， missing PARTITION or SUBPARTITION keyword 是因为语法写错，差一个字段（红色）： alter TABLE "UserCars" add "EngineNo2" nvarchar2(50); update "UserCars" set "EngineNo2" = "EngineNo"; alter TABLE "UserCars" drop column "EngineNo"; alter TABLE "UserCars" rename column "EngineNo2" to "EngineNo";
