To disable a user in SQL Server, you use the ALTER LOGIN statement for a server-level login or the REVOKE CONNECT statement for a database-level user.
How to Prevent users from viewing all Microsoft SQL databases
Go to “Users” ⇨ right-click on the user whom you want to disable (enable) and select “Properties.” In the “General” tab, check the “Disable account” field and click “OK.” If you need to enable an account — uncheck the box “Disable account” and click “OK”.
Log in with the Windows Authentication > go to the Security section. Check the login accounts, sa user will have a red arrow pointing down, indicating that it is disabled. Right click the sa user > click Properties > Status and enable the sa user. You will now be able to log in with the sa user.
The guest user can't be dropped, but guest user can be disabled by revoking its CONNECT permission by executing REVOKE CONNECT FROM GUEST within any database other than master , tempdb , or msdb .
Using Settings:
In SQL Server Management Studio's query window, highlight a table name and press ALT + F1 to display its information like columns, etc. This is actually a shortcut for running sp_help .
To re-enable a disabled user from the Local Users and Groups Manager:
There are two ways to disable the "sa" account. One way, in SSMS, is to right click on the login and select properties>status>Login: disabled. Another way is via t-sql, with this command: "Alter Login [sa] disable". The sa account can still own the databases but yet still be disabled.
The SQL LIKE Operator
The LIKE operator is used in a WHERE clause to search for a specified pattern in a column. There are two wildcards often used in conjunction with the LIKE operator: The percent sign % represents zero, one, or multiple characters. The underscore sign _ represents one, single character.
Disabled user accounts refer to accounts within a system that have been deactivated and are no longer able to access resources, which can be searched for using specific command-line syntax in an Active Directory implementation.
In the ADUC console, navigate to the OU, where you can locate the users. Highlight the desired AD accounts that you want to deactivate. Right-click on any of the highlighted accounts and choose Disable Account from the context menu to deactivate all selected accounts simultaneously.
Once activated, the functionality can not be deactivated. Certain apps won't function. You can simulate not having person accounts in the system, but it will still have impact.
Then, in Microsoft SQL Server Management Studio,
Show/Hide the result panel
CTRL + R can be used to toggle show/hide query result pane.
1) Open SQL Server Management Studio. Select Security/Login. Select the login you want to make subject to the password lockout policy. Select Enforce password policy.
Use sp_change_users_login to link a database user in the current database with a SQL Server login. If the login for a user changes, use sp_change_users_login to link the user to the new login without losing user permissions.

The Ctrl + F4 keyboard shortcut is primarily used to close the active tab or window within an application, making it great for quickly closing one document or webpage without exiting the whole program, unlike Alt + F4, which closes the entire application. In web browsers, it closes the current tab; in programs like Microsoft Excel, it closes the active workbook, leaving Excel open.
Foreign keys link data in one table to the data in another table. A foreign key column in a table points to a column with unique values in another table (often the primary key column) to create a way of cross-referencing the two tables.
