Oracle 11g 開始，  Oracle 中沒有“auto_increment”或“identity”列這樣的東西 。 可以使用序列和触發器輕鬆地對其建模： 創建資料庫 CREATE TABLE SYSTEM_STATUS_ROW ( ROW_ID NUMBER(38,0 ) NOT NULL  PRIMARY KEY , SERVICE VARCHAR2( 50 ) NOT NULL, CREATEDAT TIMESTAMP NOT NULL,   ISALIVE NUMBER(38,0 ) DEFAULT 0, RESPONSECODE NUMBER ); 程序列 CREATE SEQUENCE SYSTEM_STAUTS_LOG_ROW INCREMENT BY 1 START WITH 1 ; 觸發程式(tigger) CREATE OR REPLACE TRIGGER SYSTEM_STAUTS_LOG_ROW BEFORE INSERT ON SYSTEM_STAUTS_LOG FOR EACH ROW BEGIN SELECT SYSTEM_STATUS_ROW .NEXTVAL INTO :new. row_id FROM dual; END; ------------------------------------------- IDENTITY專欄現已在 Oracle 12c 上可用： create table t1 ( c1 NUMBER GENERATED by default on null as IDENTITY , c2 VARCHAR2( 10 ) ); create table t1 ( c1 NUMBER GENERATED ALWAYS as IDENTITY ( START with 1 INCREMENT by 1 ), c2 VARCHAR2( 10 ) ); ------------------------------------------ 或者，Oracle 12 還允許使用序列作為默認值： CREAT...
