How do you set user table permissions in SQL Server?

In SQL Server, you can use the GRANT statement to establish permissions for user tables.

Firstly, you need to have sufficient privileges to perform this operation, such as being a member of the sysadmin or db_owner roles.

Here are some common examples of GRANT statements:

1. Give the user SELECT permission:
   GRANT SELECT ON table_name TO username;
2. Grant the user INSERT permission:
   GRANT INSERT ON table_name TO username;
3. Grant the user UPDATE permission:
   GRANT UPDATE ON table_name TO user_name;
4. Grant user permission to delete:
   GRANT DELETE ON table_name TO user_name;
5. Grant all permissions to the user:
   GRANT ALL ON table_name TO username;

In these examples, “table name” refers to the name of the table for which permissions are being granted, and “username” refers to the user or role for which permissions are being granted.

In addition to the GRANT statement, you can also use the REVOKE statement to revoke granted permissions.

For example, to revoke the SELECT permission, you can use the following REVOKE statement:
REVOKE SELECT ON table name FROM username;

Please note that permission settings can potentially impact the security and integrity of the database, so before granting permission, ensure that appropriate security measures are taken and carefully evaluate users’ operational needs for the table.
