当用到自增序列，需要用到触发器的时候，当我连续执行创建多个触发器时，总是报编译通过，但存在警告或错误。
---1.应用信息 drop table app_info cascade constraints; create table APP_INFO ( id NUMBER(9) not null, appid VARCHAR2(255) default NULL, appkey VARCHAR2(255) default NULL, md5_key VARCHAR2(255) default NULL, aes_key VARCHAR2(255) default NULL, permission VARCHAR2(3000) default NULL, email VARCHAR2(255) default NULL, password VARCHAR2(255) default NULL, ras_public_key VARCHAR2(255) default NULL, constraint APP_INFO primary key (id) ); drop sequence app_info_id; create sequence app_info_id increment by 1 start with 1 nomaxvalue nominvalue nocache; CREATE OR REPLACE TRIGGER addAppInfo BEFORE INSERT ON App_INFO FOR EACH ROW BEGIN SELECT app_info_id.nextval INTO :new.id FROM dual; END; ---2.unit信息 drop table unit_info cascade constraints; create table UNIT_INFO ( UNIT_ID NUMBER(9) not null, USERID VARCHAR2(255) default NULL, UNIT_NAME VARCHAR2(128) default NULL, UNIT_LINKMAN VARCHAR2(64) default NULL, ORGANIZATION_CODE VARCHAR2(64) default NULL, constraint UNIT_INFO primary key (UNIT_ID) ); drop sequence unit_info_id; create sequence unit_info_id increment by 1 start with 1 nomaxvalue nominvalue nocache; CREATE OR REPLACE TRIGGER addUnitInfo BEFORE INSERT ON UNIT_INFO FOR EACH ROW BEGIN SELECT unit_info_id.nextval INTO :new.unit_id FROM dual; END;
错误截图如下：
这种创建是失败的，因为触发器需要先编译，每创建一个触发器，需要以“/”结束，然后才能执行下一个。
正确的做法应该是这样的;
---1.应用信息 drop table app_info cascade constraints; create table APP_INFO ( id NUMBER(9) not null, appid VARCHAR2(255) default NULL, appkey VARCHAR2(255) default NULL, md5_key VARCHAR2(255) default NULL, aes_key VARCHAR2(255) default NULL, permission VARCHAR2(3000) default NULL, email VARCHAR2(255) default NULL, password VARCHAR2(255) default NULL, ras_public_key VARCHAR2(255) default NULL, constraint APP_INFO primary key (id) ); drop sequence app_info_id; create sequence app_info_id increment by 1 start with 1 nomaxvalue nominvalue nocache; CREATE OR REPLACE TRIGGER addAppInfo BEFORE INSERT ON App_INFO FOR EACH ROW BEGIN SELECT app_info_id.nextval INTO :new.id FROM dual; END; / ---2.unit信息 drop table unit_info cascade constraints; create table UNIT_INFO ( UNIT_ID NUMBER(9) not null, USERID VARCHAR2(255) default NULL, UNIT_NAME VARCHAR2(128) default NULL, UNIT_LINKMAN VARCHAR2(64) default NULL, ORGANIZATION_CODE VARCHAR2(64) default NULL, constraint UNIT_INFO primary key (UNIT_ID) ); drop sequence unit_info_id; create sequence unit_info_id increment by 1 start with 1 nomaxvalue nominvalue nocache; CREATE OR REPLACE TRIGGER addUnitInfo BEFORE INSERT ON UNIT_INFO FOR EACH ROW BEGIN SELECT unit_info_id.nextval INTO :new.unit_id FROM dual; END; /
注意：存储过程也是一样的。
