项目中用到了Quartz，也算是Quartz的一个示例。
源库创建数据同步表SYNC_DATA：
CREATE TABLE SYNC_DATA( ID VARCHAR2(36) NOT NULL, TABLE_NAME VARCHAR2(50) NOT NULL, COMMAND VARCHAR2(10) NOT NULL, TABLE_KEY VARCHAR2(50) NOT NULL, DATA_ID VARCHAR2(50) NOT NULL, FAIL_COUNT INT NOT NULL, CREATE_TIME DATE NOT NULL, UPDATE_TIME DATE , CONSTRAINT sync_data_PK PRIMARY KEY (ID) ) ; COMMENT ON TABLE SYNC_DATA IS '业务数据同步表' ; COMMENT ON COLUMN SYNC_DATA.ID IS '主键' ; COMMENT ON COLUMN SYNC_DATA.TABLE_NAME IS '表名' ; COMMENT ON COLUMN SYNC_DATA.COMMAND IS '命令' ; COMMENT ON COLUMN SYNC_DATA.TABLE_KEY IS '表主键' ; COMMENT ON COLUMN SYNC_DATA.DATA_ID IS '数据ID' ; COMMENT ON COLUMN SYNC_DATA.FAIL_COUNT IS '失败次数' ; COMMENT ON COLUMN SYNC_DATA.CREATE_TIME IS '创建时间' ; COMMENT ON COLUMN SYNC_DATA.UPDATE_TIME IS '更新时间' ;
新增修改删除触发器示例(oracle版)：
