在实体框架中使用MySQL PASSWORD（）

Question

We have an old MySQL database that has passwords stored using the MySQL function PASSWORD(). Is there a way using Entity Framework in C# to select the row with the password?

The old way would be to do a sql query

SELECT * FROM `employees` WHERE `id` = @id AND `password` = PASSWORD(@pword);

The @id and @pword are then passed to the .Net Connector as parameters.

In Entity we do this

var query = from employeeRow in context.employees 
            where employeeRow.id.Equals(username_txt.Text) 
            select employeeRow; 
_foundEmployee = query.SingleOrDefault();

But this will return the row data without checking the password. How would I check the password that has been hashed with MySQL PASSWORD()?

Answer 1

where employeeRow.id.Equals(username_txt.Text) && employeeRow.password.Equals(hashedPassword)

You need to do password hashing separately. I'd suspect mysql documentation will tell you what algorithm PASSWORD() method uses.
