关于oracle数据库id重置存储

–创建该存储，创建完成之后进行存储测试

右键该存储，Test测试

输入参数 owner 用户 tableName 需要重置的表名 然后运行。就会重新排列该表的id值。

以下是存储内容：

create or replace procedure P_ResetObjectID(owner in NVARCHAR2, tablename in NVARCHAR2)
is

reg_id         pls_integer;
owner_l        VARCHAR2(64);
table_l        VARCHAR2(64);
pipe_name         VARCHAR2(30);
max_id           NUMBER;
stmt           varchar2(512);
sequence_name     VARCHAR2(64);
begin
    owner_l := UPPER(owner);
    table_l := UPPER(tablename);

    stmt := 'SELECT registration_id FROM SDE.table_registry '||
            'WHERE owner ='''|| owner_l ||''' AND table_name = '''|| table_l ||'''';
    EXECUTE IMMEDIATE stmt INTO  reg_id;
    if reg_id is null then return;
    end if;
    pipe_name := 'ArcSDE_IdPipe' || TO_CHAR (reg_id);
    --清除arcgis缓存管道
    stmt := 'select sys.dbms_pipe.remove_pipe('''||pipe_name||''') from dual ';
    EXECUTE IMMEDIATE stmt;
    --更新oid
    stmt := 'update '||table_l||' set objectid=rownum ';
    EXECUTE IMMEDIATE stmt;
    --获取最大oid
    stmt := 'select max(objectid)  from '||table_l;
    EXECUTE IMMEDIATE stmt INTO  max_id;
    if max_id is NULL then return;
    end if;
    --修改序列的当前值
    sequence_name := 'R' || TO_CHAR (reg_id);
    stmt := 'drop  sequence '||sequence_name||' ';
    EXECUTE IMMEDIATE stmt;
    stmt := 'create sequence '||sequence_name||' minvalue 1 maxvalue 2147483647 start with '||max_id||' increment by 16 cache 20';
    EXECUTE IMMEDIATE stmt;
    stmt := 'grant select on '||owner_l||'.'||sequence_name||' to public';
    EXECUTE IMMEDIATE stmt;
end P_ResetObjectID;
