For the GUI minded people, you can:
- Right click the Database in Management Studio.
- Choose Properties.
- Select Permissions.
- If your user does not show up in the list, choose Search and type their name.
- Select the user in the Users or Roles list.
- In the lower window frame, Check the Select permission under the Grant column.
SQL>create user scott_read_only_user identified by readonly; SQL>grant create session to scott_read_only_user; SQL>grant select any table to scott_read_only_user; This will only grant read-only to scott tables, you would need to connect to another schema owner to grant them read-only access.
Create a read-only user in PostgreSQL
- CREATE USER username WITH PASSWORD 'your_password';
- GRANT CONNECT ON DATABASE database_name TO username;
- GRANT USAGE ON SCHEMA schema_name TO username;
- GRANT SELECT ON table_name TO username;
- GRANT SELECT ON ALL TABLES IN SCHEMA schema_name TO username;
To change directory permissions for everyone, use “u” for users, “g” for group, “o” for others, and “ugo” or “a” (for all). chmod ugo+rwx foldername to give read, write, and execute to everyone. chmod a=r foldername to give only read permission for everyone.
First, Login to the PhpMyAdmin interface and go to the User Account tab and click on “Add user account“.
- After that fill the required information.
- No Click on “GO“.
- Now in the User Account tab, you can see the newly created user.
- Here you have to select those databases whose backups are taken by this user.
Read, write and execute permissions are set for directories as well as files. Read permission means that the user may see the contents of a directory (e.g. use ls for this directory.) Write permission means that a user may create files in the directory.
Read-only Files
- Open Windows Explorer and navigate to the file you want to edit.
- Right-click the file name and select "Properties."
- Select the "General" tab and clear the "Read-only" check box to remove the read-only attribute or select the check the box to set it.
Are the file properties set to read-only? You can check the file properties by right-clicking on the file and choosing Properties. If the Read-only attribute is checked, you can uncheck it and click OK.
To change the read-only attribute, follow these steps:
- Right-click the file or folder icon.
- Remove the check mark by the Read Only item in the file's Properties dialog box. The attributes are found at the bottom of the General tab.
- Click OK.
A file that's marked as read-only usually implies that the file shouldn't be altered or that great caution should be taken before making changes to it. Other things besides files can also be read-only like particularly configured flash drives and other solid state storage devices like SD cards.
To grant the Densify Connector read-only access to your vCenter Server:
- In the vSphere Client, right-click your vCenter and select Add Permission.
- Click Add, double-click to select your new user and click OK to add this user with read-only permission. Then check Propagate to Child Objects and click OK.
The read-only attribute may be set in the file properties window. To see this option, right-click the JPG file and choose "Properties." Unchecking "Read-Only" from the Attribute section clears the read-only restriction and allows you to modify the file.
To do so:
- From Explorer, search for the Excel File in question.
- Right-click on the Excel file you want to edit.
- Select Properties.
- Go to the bottom of the General Tab.
- Uncheck the Read Only check box.
- Click OK to finalize.
Most data files in a user account's home directory, such as text files, word processor files, and so on, should have 110/6/rw- permissions for that account and 000/0/--- for group and world permissions, while most subdirectories within that home directory should have 111/7/rwx for the owner and 000/0/--- for the group
Follow this simple steps and mark your database “read-write”.
- Right-click database you need to mark as read-write.
- Select “Properties”
- In the “Database Properties” window select “Options” tab.
- Scroll down and find “State” tab, go to “Database Read-Only” statement and select “False”
A read-only database allows users to read but not modify data. You can set the database to READ_ONLY in T-SQL using ALTER DATABASE: ALTER DATABASE MyDatabase SET READ_ONLY; You can also set the database to read-only from the Object Explorer in SQL Server Management Studio.
The public server role is granted VIEW ANY DATABASE permission and the CONNECT permission on the default endpoints. Actually, The public server role is not a fixed server role, because the permissions can be changed, but every user belongs to the public database role by default.
To create a user, complete the following steps:
- In the SQL Server Management Studio, open Object Explorer.
- Click Server_instance_name > Security > Logins.
- Right-click Logins and select New Login.
- On the General page, in the Login name field, type the name for a new user.
- Select SQL Server authentication.
db_datareader. The db_datareader role allows a user to be able to issue a SELECT statement against all tables and views in the database. DENY for a user (or a role the user is a member of) will still block the SELECT, however.
Ready to Connect
- CREATE LOGIN [rptLogin] WITH password='add-pw-here';
- CREATE USER [rptUser] FROM LOGIN [rptLogin] WITH DEFAULT_SCHEMA=[dbo];
- CREATE USER [rptUser] FROM LOGIN [rptLogin] WITH DEFAULT_SCHEMA=[dbo];
Grant table-level permissions in SQL Server
- Enter a descriptive Login name, select SQL Server authentication, and enter a secure password.
- Select the User Mapping tab, check the box next to the desired database, confirm that only 'public' is selected, and click OK.
In computing, Open Database Connectivity (ODBC) is a standard application programming interface (API) for accessing database management systems (DBMS). The designers of ODBC aimed to make it independent of database systems and operating systems.
mysql> FLUSH PRIVILEGES; when we grant some privileges for a user, running the command flush privileges will reloads the grant tables in the mysql database enabling the changes to take effect without reloading or restarting mysql service. The command closes all tables which are currently open or in use.
To show/list the users in a MySQL database, first log into your MySQL server as an administrative user using the mysql command line client, then run this MySQL query:mysql> select * from mysql.user; However, note that this query shows all of the columns from the mysql.
To GRANT ALL privileges to a user , allowing that user full control over a specific database , use the following syntax: mysql> GRANT ALL PRIVILEGES ON database_name.* TO 'username'@'localhost';
Select a user under "users and privilege" and click the tab "schema privileges". Click "add entry", pick a host and schema. Then al you have to do is check the "select" privilege. This user has read only rights now.
How to see/get a list of MySQL/MariaDB users accounts
- Step 1 – Login to mysql.
- Step 2 – Show users.
- Step 3 – Show users along with host name where they are allowed to login.
- Step 4 – How to avoid repetitions of user names?
- Step 5 – Get a listing of the fields in the mysql.user.
- Step 6 – Finding out user rights.
The DROP USER statement removes one or more MySQL accounts and their privileges. It removes privilege rows for the account from all grant tables. An error occurs for accounts that do not exist. To use DROP USER , you must have the global CREATE USER privilege, or the DELETE privilege for the mysql system database.
USAGE is a way to tell MySQL that an account exists without conferring any real privileges to that account. They merely have permission to use the MySQL server, hence USAGE . It corresponds to a row in the `mysql`. `user` table with no privileges set.
To create a new MariaDB user, type the following command: CREATE USER 'user1'@localhost IDENTIFIED BY 'password1'; In this case, we use the 'localhost' host-name and not the server's IP. This practice is commonplace if you plan to SSH in to your server, or when using the local client to connect to a local MySQL server.
