Oracle creates users with query permission only

  One 、 Create user

--  Create user

create user USERB identified by " password " default tablespace  Table space ;

-- Grant login permission

grant connect to estate_user;

-- Grant permission to query any table

grant select any table to userName; 

Two 、 Grant permission to view all tables or a table or view under a user

-- stay USERA Query all tables under , form sql

select 'grant select on USERA.' || table_name || ' to USERB;' from user_tables;

-- stay USERA In the implementation of grant Of sql

grant select on USERA.tableA to USERB;

Sign in USERB Query table , You need to bring the user name of the original creation user ： for example ：

select * from USERA.TABLEA 

3、 ... and 、 If you don't want to bring the original user name, you need to create synonyms

-- The first thing you need to sys User authorization USER_B Create synonym permissions :

GRANT CREATE SYNONYM TO USERB;

-- Create synonyms ：

create synonym USERB.TABLENAME1 for USERA.TABLENAME1 ;

-- Batch create synonyms , stay USERA In the implementation of ：

select 'grant select on USERA.' || table_name || ' to USERB;' from user_tables;

-- stay USERB In the implementation of grant sentence .

After building synonyms ,pl/sql developer See the table , Still can't see all the tables , But fortunately, it can USERB. Can point out all the watches ：

View synonyms under users

SELECT * FROM DBA_SYNONYMS where OWNER = 'USERB';

Delete synonyms

drop synonym sysn_name;

Four 、 Delete user :

drop user htqryall cascade;
