mysql查询所有数据库对象_SQL语句查询数据库对象1、⽤户
查看当前⽤户的缺省表空间mysql查看所有存储过程
SQL>select username,default_tablespace from user_users;
查看当前⽤户的⾓⾊
SQL>select * from user_role_privs;
查看当前⽤户的系统权限和表级权限
SQL>select * from user_sys_privs;
SQL>select * from user_tab_privs;
显⽰当前会话所具有的权限
SQL>select * from session_privs;
显⽰指定⽤户所具有的系统权限
SQL>select * from dba_sys_privs where grantee='GAME';
显⽰特权⽤户
select * from v$pwfile_users;
显⽰⽤户信息(所属表空间)
jquery设置css属性
select default_tablespace,temporary_tablespace
from dba_users where username='GAME';
显⽰⽤户的PROFILE
select profile from dba_users where username='GAME';
2、表
查看⽤户下所有的表
SQL>select * from user_tables;
查看名称包含log字符的表
SQL>select object_name,object_id from user_objects
where instr(object_name,'LOG')>0;
查看某表的创建时间
SQL>select object_name,created from user_objects where object_name=upper('&table_name');
查看某表的⼤⼩
redhat7SQL>select sum(bytes)/(1024*1024) as "size(M)" from user_segments
where segment_name=upper('&table_name');
查看放在ORACLE的内存区⾥的表
SQL>select table_name,cache from user_tables where instr(cache,'Y')>0;
3、索引
select case 语句
查看索引个数和类别
SQL>select index_name,index_type,table_name from user_indexes order by table_name；查看索引被索引的字段
SQL>select * from user_ind_columns where index_name=upper('&index_name');
查看索引的⼤⼩
SQL>select sum(bytes)/(1024*1024) as "size(M)" from user_segments
where segment_name=upper('&index_name');
4、序列号
查看序列号，last_number是当前值
SQL>select * from user_sequences;
5、视图
查看视图的名称
SQL>select view_name from user_views;
查看创建视图的select语句
SQL>set view_name,text_length from user_views;
app源码安装教程SQL>set long 2000; 说明：可以根据视图的text_length值设定set long 的⼤⼩
SQL>select text from user_views where view_name=upper('&view_name');
指令集和汇编语言的关系6、同义词
查看同义词的名称
SQL>select * from user_synonyms;
7、约束条件
查看某表的约束条件
SQL>select constraint_name, constraint_type,search_condition, r_constraint_name
from user_constraints where table_name = upper('&table_name');
SQL>straint_straint_lumn_name
from user_constraints c,user_cons_columns cc
where c.owner = upper('&table_owner') and c.table_name = upper('&table_name')
and c.owner = cc.owner straint_name = cc.constraint_name
order by cc.position;
8、存储函数和过程
查看函数和过程的状态
SQL>select object_name,status from user_objects where object_type='FUNCTION'; SQL>select object_name,status from user_objects where object_type='PROCEDURE';
查看函数和过程的源代码
SQL>select text from all_source where ōwner=user and name=upper('&plsql_name');
