Oracle常用语句

1、创建表空间

create tablespace test_data
data file 'F:/oracle/test_data.dbf'
size 500M autotextend on;

create tablespace test_temp
temp file 'F:/oracle/test_temp.dbf'
size 500M autoextend on;

2、创建角色

CREATE USER "TESTUSER" PROFILE "DEFAULT"
IDENTIFIED BY "PASSWORD" DEFAULT TABLESPACE
"TEST_DATA"
TEMPORARY TABLESPACE "TEST_TEMP"
ACCOUNT UNLOCK;

3、赋予权限

GRANT "CONNECT" TO "TESTUSER";
GRANT "DBA" TO "TESTUSER";

4、imp导入

imp TESTUSER/PASSWORD@orcl ignore=y FILE=E:\test.dmp full=y;

5、exp导出整个库

exp TESTUSER/PASSWORD@orcl FILE=E:\test.dmp full=y;

6、exp导出指定用户数据

exp TESTUSER/PASSWORD@orcl FILE=E:\test.dmp

7、创建序列号

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

8、删除用户

drop user ×× cascade

9、删除表空间

DROP TABLESPACE tablespace_name INCLUDING CONTENTS AND DATAFILES;

10、分页查询

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;

11、将锁定用户解锁

alter user username account unlock;

12、超级用户登录

sqlplus / as sysdba

13、修改用户密码

alter user user01 identified by user10;

14、指定登录实例

sqlplus system/kingdee@orcl as sysdba;

15、从回收站中恢复数据表内容

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";

16、批量删除、启用外键
–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'

17、添加提取中文首字母拼音函数

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