1.在数据库添加自增序列
CREATE SEQUENCE "LCM"."TOPICSTAT_ID" MINVALUE 1 MAXVALUE 999999999999999999999999999 INCREMENT BY 1 START WITH 242 NOCACHE NOORDER NOCYCLE NOPARTITION ;
2.引用自增序列
CREATE TABLE "LCM"."TOPICSTAT"
( "ID" NUMBER NOT NULL ENABLE,
"VIN" NVARCHAR2(100) NOT NULL ENABLE,
"LANG" NVARCHAR2(100) NOT NULL ENABLE,
"NO" NVARCHAR2(100) NOT NULL ENABLE,
"COUNTTIME" DATE NOT NULL ENABLE
) SEGMENT CREATION IMMEDIATE

BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT)
TABLESPACE "USERS" ;
COMMENT ON COLUMN "LCM"."TOPICSTAT"."COUNTTIME" IS '点击时间';
3.插入数据
String sql = "insert into TOPICSTAT values(TOPICSTAT_ID.nextval,'"+vin+"','"+lang+"','"+page+"',to_date('"+countTime+"','yyyy-mm-dd hh24:mi:ss'))";
