There are times that my user's access to that table is revoked.
So, to avoid the ETL failing, before reading the table I must verify if I have permission to do it.

This coding style allows the database to distinguish between code and data, regardless of what user input is supplied.
A user that has been assigned a role will only be able to exercise the privileges of that role.
Only users that have administrative privileges can create/drop roles.
In some shops, the path of least resistance is to give developers system admin access to instances of SQL Server.
It is often a better choice to tighten things up a little more than that - only granting access to the databases and objects that they should be able to access.Complete a brief survey to get a complimentary 70-page whitepaper featuring the best methods and solutions for your virtual environment, as well as hypervisor-specific management advice from Tech Target experts. Security is becoming more and more of a concern these days.Prepared statements ensure that an attacker is not able to change the intent of a query, even if SQL commands are inserted by an attacker.In the safe example below, if an attacker were to enter the user ID of tom' or '1'='1, the parameterized query would not be vulnerable and would instead look for a username which literally matched the entire string tom' or '1'='1.String custname = Parameter("customer Name"); // This should REALLY be validated too // perform input validation to detect attacks String query = "SELECT account_balance FROM user_data WHERE user_name = ?
