以下是两个简单的创建案例：

create table "pc_pp_product"
(
"phone_id" VARCHAR2(32 BYTE) NOT NULL ENABLE,--主键
"color" VARCHAR2(32 BYTE),
"phone_type" VARCHAR2(32 BYTE),
"weidth" VARCHAR2(32 BYTE),
"length" VARCHAR2(32 BYTE),
"price" VARCHAR2(32 BYTE),
"category" VARCHAR2(32 BYTE),
CONSTRAINT "phone_id1445" PRIMARY KEY ("phone_id")
);
COMMENT ON COLUMN "pc_pp_product"."phone_id" IS '产品表主键';
COMMENT ON COLUMN "pc_pp_product"."color" IS '颜色';
COMMENT ON COLUMN "pc_pp_product"."phone_type" IS '型号';
COMMENT ON COLUMN "pc_pp_product"."weidth" IS '宽度';
COMMENT ON COLUMN "pc_pp_product"."length" IS '大小';
COMMENT ON COLUMN "pc_pp_product"."price" IS '价格';
COMMENT ON COLUMN "pc_pp_product"."category" IS '类别';
