以前没写过储存过程,恰好利用这次机会练练手,特写此博客,方便以后查阅:
序号 对象名称 类型 说明
1 synBaseDataTemp table 临时表
2 synBaseDataHistory table 同步历史记录
3 synBaseDataTemp_Sequence SEQUENCE 设置字段ID自增
4 tri_synBaseDataTemp TRIGGER 当临时表中有新增记录时,ID自动增加1
5 tri_基础数据表名 TRIGGER 当CCS基础数据表有增 删 改操作时,会自动触发在ECCS基础数据
表增加记录(共32个)
6 baseDataSynProc procedure 将临时表中记录的信息同步到ECCS中,同时将同步记录
增加到synBaseDataHistory中,并将同步的synBaseDataTemp信息删除
创建同步相关表:
[sql] view plaincopy
/*创建表synBaseDataTemp*/
CREATE TABLE synBaseDataTemp
(
id number(15,0) NOT NULL,
condition varchar2(300) not null,
tableName varchar2(40) not null,
operateType varchar2(20) not null,
operateDate date,
failFlag varchar2(1),
failTimes integer,
PRIMARY KEY (id)
);
comment on table synBaseDataTemp is '同步临时表';
comment on column synBaseDataTemp.id is '自增列,主键';
comment on column synBaseDataTemp.condition is '表主键条件';
comment on column synBaseDataTemp.tableName is '表名';
comment on column synBaseDataTemp.operateType is '操作类型';
comment on column synBaseDataTemp.operateDate is '操作时间';
comment on column synBaseDataTemp.failFlag is '失败标志,1失败';
comment on column synBaseDataTemp.failTimes is '失败次数';
/*创建表synHistory*/
CREATE TABLE synBaseDataHistory
(
id number(15,0) NOT NULL,
condition varchar2(300) not null,
tableName varchar2(40) not null,
operateType varchar2(20) not null,
operateDate date,
PRIMARY KEY (id)
);
comment on table synBaseDataHistory is '同步历史记录表';
comment on column synBaseDataHistory.id is '自增列,主键';
comment on column synBaseDataHistory.condition is '表主键条件';
comment on column synBaseDataHistory.tableName is '表名';
comment on column synBaseDataHistory.operateType is '操作类型';
comment on column synBaseDataHistory.operateDate is '操作时间';
/*为表synBaseDataTemp的ID创建自增列*/
--创建自动增长序列
CREATE SEQUENCE synBaseDataTemp_Sequence
INCREMENT BY 1
START WITH 1
NOMAXVALUE
NOCYCLE
CACHE 10;
--创建触发器
CREATE OR REPLACE TRIGGER tri_synBaseDataTemp BEFORE
insert ON synBaseDataTemp FOR EACH ROW
begin
select synBaseDataTemp_Sequence.nextval into:New.id from dual;
end;
为每张表创建触发器,共32张表,以一张表作为实例:
[sql] view plaincopy
</pre><p> </p><pre class="sql" name="code">/*为表GGSYSTEM创建触发器,当有相关操作时,在synBaseDataTemp中存入相关信息*/
CREATE OR REPLACE TRIGGER tri_GGSYSTEM
AFTER INSERT or DELETE or UPDATE --指定触发时机触发
ON GGSYSTEM
REFERENCING NEW as new_value
FOR EACH ROW --说明创建的是行级触发器
BEGIN
--将修改前数据插入到临时表synBaseDataTemp,供存储过程调用。
if inserting then
INSERT INTO synBaseDataTemp
(condition, tableName, operateType, operateDate)
VALUES
('SYSTEMCODE=' || chr(39) || :new_value.systemCode || chr(39),
'GGSYSTEM',
'INSERT',
sysdate);
elsif updating then
INSERT INTO synBaseDataTemp
(condition, tableName, operateType, operateDate)
VALUES
('SYSTEMCODE=' || chr(39) || :new_value.systemCode || chr(39),
'GGSYSTEM',
'UPDATE',
sysdate);
elsif deleting then
INSERT INTO synBaseDataTemp
(condition, tableName, operateType, operateDate)
VALUES
('SYSTEMCODE=' || chr(39) ||
ld.systemCode || chr(39),
'GGSYSTEM',
'DELETE',
sysdate);
end if;
END;
创建触发器后,下面是存储过程:

创建job,定时执行储存过程:
[sql] view plaincopy
BEGIN
DBMS_SCHEDULER.CREATE_JOB(job_name => 'jobsynproc', --job名称，自己设
job_type => 'STORED_PROCEDURE', --类型为存储过程
job_action => 'ccs_synproc', --存储过程名称为proc
start_date => to_date('30-12-2011 00:00:00',
'dd-mm-yyyy hh24:mi:ss'), --开始执行时间
enabled => TRUE, --自动启用
auto_drop => false,
repeat_interval => 'FREQ=Monthly;Interval=1');
END;
在这之前,必须授权用户有增删改的权限,并且创建同义词,以便储存过程能顺利执行:
1.依照DBA用户登录执行sql命令：grant create synonym to 被授权用户;
2.如果你需要对某表可以修改等权限：需执行：grant select,insert,update on monitor_sys_log to 被授权用户;
3.用"被授权用户"登录创建同义词：create synonym monitor_sys_log(同义词名称) for 拥有表用户.monitor_sys_log（表名）;
