--建递增序列
CREATE SEQUENCE LZEAM_SP_LOOP_EQ_SEQ MINVALUE 1 INCREMENT BY 1 START WITH 1
测试:
SELECT LZEAM_SP_LOOP_EQ_SEQ.NEXTVAL FROM DUAL
--建触发器
CREATE OR REPLACE TRIGGER LZEAM.LZEAM_SP_LOOP_EQ_TRIGGER BEFORE INSERT ON SP_LOOP_EQ FOR EACH ROW BEGIN SELECT LZEAM.LZEAM_SP_LOOP_EQ_SEQ.NEXTVAL INTO :NEW.LOOP_EQ_CODE FROM DUAL; END;
--查触发器
SELECT * FROM USER_TRIGGERS;
/**启/禁用触发器*/
