Oracle常用命令

1、创建表空间

create tablespace rofly_data
datafile 'F:oracledb
ofly_data.dbf'
size 500m autoextend on;

create temporary tablespace rofly_temp
tempfile 'F:oracledb
ofly_temp.dbf'
size 300m autoextend on;

2、创建角色

CREATE USER "OAROFLY" PROFILE "DEFAULT" 
IDENTIFIED BY "OAPASSWORD" DEFAULT TABLESPACE 
"ROFLY_DATA" 
TEMPORARY TABLESPACE "ROFLY_TEMP" 
ACCOUNT UNLOCK;

3、赋予权限

GRANT "CONNECT" TO "OAROFLY";
GRANT "DBA" TO "OAROFLY";

4、imp导入

imp JTOA/OAPASSWORD@orcl ignore=y FILE=E:	est.dmp full=y;

5、exp导出整个库

exp OAROFLY/OAPASSWORD@orcl FILE=E:
ofly_oa.dmp full=y;

6、exp导出指定用户数据

exp OAXY/OAPASSWORD@ORCL FILE=d:oracledbxy_oa_dmp;

7、oracle创建序列号

create sequence JXBrhavior_id_seq start with 1 maxvalue 99999999999999999999 minvalue 1 nocycle cache 20 noorder

9、Oracle删除用户

drop user ×× cascade

10、Oracle删除表空间

DROP TABLESPACE tablespace_name INCLUDING CONTENTS AND DATAFILES;

11、Oracle 查询数据分页

select * 
from (select ROWNUM as num,A.* from 
(select * from F_FC_MESSAGE where 1=1 and fcolumnId='8a3084e854d34dd101556703a97629f3' order by FID desc) A where rownum <= 165)
where num >= 151;

12、Oracle将锁定的用户解锁

alter user username account unlock;

13、Oracle超级用户登陆

sqlplus / as sysdba 

14、Oracle修改用户密码

alter user user01 identified by user10;

15、Oracle指定实例登陆

sqlplus system/kingdee@orcl as sysdba;

16、Oracle从回收站中还原已删除的数据表

select * from recyclebin where original_name = 'F_I_INSPECT_OTHER_RULE';

create table F_I_INSPECT_OTHER_RULE_BAK AS
select *
from ioffice."BIN$i90r3SvaSo66IED9xsMYIg==$0";

17、Oracle批量删除、禁用、启用约束

--删除所有外键约束(复制列表SQL执行)
select 'alter table '||table_name||' drop constraint '||constraint_name||';' from user_constraints where constraint_type='R'  
--禁用所有外键约束(复制列表SQL执行)
select 'alter table '||table_name||' disable constraint '||constraint_name||';' from user_constraints where constraint_type='R'   
--启用所有外键约束(复制列表SQL执行)
select 'alter table '||table_name||' enable constraint '||constraint_name||';' from user_constraints where constraint_type='R' 

18、Oracle添加拼音函数提取中文首字母

CREATE OR REPLACE FUNCTION GET_PYJM (P_NAME IN VARCHAR2)
    RETURN VARCHAR2
AS
    V_COMPARE   VARCHAR2 (100);
    V_RETURN    VARCHAR2 (4000);

        END;
    BEGIN
        FOR I IN 1 .. LENGTH (P_NAME)
        LOOP
