Oracle EX 11g创建用户表和表空间授权

1. 创建数据库目录

mkdir -p /home/oracle/Documents/db

1. 创建用户

create user cheng identified by 123456;

1. 授权

grant connect,resource to cheng;
grant create any sequence to cheng;
grant create any table to cheng;
grant delete any table to cheng;
grant insert any table to cheng;
grant select any table to cheng;
grant unlimited tablespace to cheng;
grant execute any procedure to cheng;
grant update any table to cheng;
grant create any view to cheng;

1. 建立表空间

create tablespace testspace 
datafile '/home/oracle/Documents/db/TESTSPACE.dbf' 
size 1000M
autoextend on next 5M maxsize 3000M;

1. 授予用户使用表空间的权限：

alter user cheng quota unlimited on testspace;

附Oracle最高效分页和插入后返回自增长主键值：

SELECT *
FROM
  (
    SELECT
      ROWNUM AS rn,
      a.*
    FROM
      (SELECT *
       FROM BOOK_INFO t
       ORDER BY t.B_ID) a
    WHERE
      ROWNUM <= #{end}
) b
WHERE
b.rn >= #{begin}



<selectKey resultType="java.math.BigDecimal" order="BEFORE" keyProperty="bId">
     SELECT BOOK_SEQ.Nextval as B_ID from DUAL
</selectKey>
