常用oracle可重复执行的脚本模板

为保证脚本的可重复执行以及丢失,涉及到数据库环境的移植等,就会使用可重复执行脚本,此处仅提供相关一些模板

说明下:该脚本需要在命令窗口执行,而不是在SQL窗口执行

创建序的脚本

 /**
  *  作者：zkongbai
  *  时间：11-30 09:22:10
  *  描述：创建序列【SEQ_ZZ_DOUBLE_RANDOM_TASK】
  *  脚本可重复执行
  */
 PROMPT SEQ_ZZ_DOUBLE_RANDOM_TASK  双随机事件脚本 创建序列
 DECLARE
     FLAG_NUM NUMBER;
 BEGIN
     SELECT COUNT(*) INTO FLAG_NUM
     FROM USER_SEQUENCES ASQ
     WHERE ASQ.SEQUENCE_NAME = UPPER('SEQ_ZZ_DOUBLE_RANDOM_TASK');
     IF FLAG_NUM = 0 THEN
         EXECUTE IMMEDIATE 'CREATE SEQUENCE SEQ_ZZ_DOUBLE_RANDOM_TASK MINVALUE 1 MAXVALUE 999999999 START WITH 1 INCREMENT BY 1 CACHE 20';
     END IF;
 END;
 /
 COMMIT;

创建表的脚本

 /**
  *  作者：zkongbai
  *  时间：11-21 09:22:10
  *  描述：创建表【双随机任务,序:SEQ_ZZ_DOUBLE_RANDOM_TASK】
  *  脚本可重复执行
  */
 PROMPT T_ZZ_DOUBLE_RANDOM_TASK 创建表
 DECLARE
     FLAG_NUM NUMBER;
 BEGIN
     SELECT COUNT(*) INTO FLAG_NUM
     FROM USER_TABLES ATS
     WHERE ATS.TABLE_NAME = UPPER('T_ZZ_DOUBLE_RANDOM_TASK');
     IF FLAG_NUM = 0 THEN
         EXECUTE IMMEDIATE 'CREATE TABLE T_ZZ_DOUBLE_RANDOM_TASK
             (
                 ID              NUMBER(8) not null,
                 EVENT_ID        NUMBER(8),
                 JUDGE_COMMENT   VARCHAR2(500),
                 JUDGE_RESULE    CHAR(1),
                 JUDGE_PERSON    NUMBER(8),
                 CREATE_TIME     DATE,

                 UPDATE_TIME     DATE,
                 CREATE_USER_ID  NUMBER(8),
                 CREATE_ORG_CODE VARCHAR2(32),
                 CONSTRAINT PK_T_ZZ_DOUBLE_RANDOM_TASK PRIMARY KEY (ID)
             )';
         -- ADD COMMENTS TO THE TABLE
         EXECUTE IMMEDIATE 'COMMENT ON TABLE T_ZZ_DOUBLE_RANDOM_TASK IS ''双随机任务,序:SEQ_ZZ_DOUBLE_RANDOM_TASK''';
         -- ADD COMMENTS TO THE COLUMNS
         EXECUTE IMMEDIATE 'COMMENT ON COLUMN T_ZZ_DOUBLE_RANDOM_TASK.EVENT_ID  IS ''事件ID''';
         EXECUTE IMMEDIATE 'COMMENT ON COLUMN T_ZZ_DOUBLE_RANDOM_TASK.JUDGE_COMMENT  IS ''评价意见''';
         EXECUTE IMMEDIATE 'COMMENT ON COLUMN T_ZZ_DOUBLE_RANDOM_TASK.JUDGE_RESULE  IS ''评价结果(1:合格,2:不合格)''';
         EXECUTE IMMEDIATE 'COMMENT ON COLUMN T_ZZ_DOUBLE_RANDOM_TASK.JUDGE_PERSON  IS ''评价人''';
         EXECUTE IMMEDIATE 'COMMENT ON COLUMN T_ZZ_DOUBLE_RANDOM_TASK.STATUS  IS ''状态.1:有效,0:无效''';
         EXECUTE IMMEDIATE 'COMMENT ON COLUMN T_ZZ_DOUBLE_RANDOM_TASK.CREATE_USER_ID  IS ''创建人''';
         EXECUTE IMMEDIATE 'COMMENT ON COLUMN T_ZZ_DOUBLE_RANDOM_TASK.CREATE_ORG_CODE  IS ''创建组织''';
     END IF;
 END;
 /
 COMMIT;

修改字段的脚本

 /**
  *  作者：zkongbai
  *  时间：2018/1/11
  *  描述：双随机任务添加字段 TASK_TYPE
  *  脚本可重复执行
  */
 PROMPT T_ZZ_DOUBLE_RANDOM_TASK 双随机任务添加字段 TASK_TYPE
 DECLARE
   FLAG_NUM NUMBER;
 BEGIN
   SELECT COUNT(*) INTO FLAG_NUM
   FROM USER_TABLES ATS
   WHERE ATS.TABLE_NAME = UPPER('T_ZZ_DOUBLE_RANDOM_TASK');
   IF FLAG_NUM > 0 THEN
     SELECT COUNT(*) INTO FLAG_NUM FROM USER_TAB_COLUMNS T
     WHERE T.TABLE_NAME = UPPER('T_ZZ_DOUBLE_RANDOM_TASK') AND T.COLUMN_NAME = UPPER('TASK_TYPE');
     IF FLAG_NUM=0 THEN
       EXECUTE IMMEDIATE 'ALTER TABLE T_ZZ_DOUBLE_RANDOM_TASK ADD TASK_TYPE CHAR(1)';
       -- ADD COMMENTS TO THE COLUMNS
       EXECUTE IMMEDIATE 'COMMENT ON COLUMN T_ZZ_DOUBLE_RANDOM_TASK.TASK_TYPE  IS ''任务类型: 1或空:市级双随机任务,2:镇街级随机任务''';
     END IF;
   END IF;
 END;
 /
 COMMIT;
