How to "iterate over" the SQL result in a stored procedure, but avoid using a cursor?

Question

I am new to working with SQL.

My goal is to email the query results to create an email. I intend to create a stored procedure and schedule it twice a week (there will be no more than 20 letters, this will not be a heavy load on e-mail) on SQL Server 2008.

SELECT ProjectCodes.ProjectCode, COUNT(Projects.ProjectsID),  ProjectApprovers.EmailApprover
FROM Projects 
INNER JOIN ProjectCodes
    ON Projects.ProjectCodesID=ProjectCodes.ProjectCodesID
INNER JOIN ProjectApprovers
    ON Projects.ProjectCodesID=ProjectApprovers.ProjectCodesID
WHERE ProjectApprovers.IsPrimaryApprover=1
group by ProjectCodes.ProjectCode, ProjectApprovers.EmailApprover

This returns something similar to:

+-------------+-------+--------------+
| ProjectCode | Count | EmailAddress |
+-------------+-------+--------------+
| Code1       |     4 | Email1       |
| Code2       |     2 | Email2       |
| Code3       |     2 | Email3       |
| Code4       |     3 | Email4       |
+-------------+-------+--------------+

What I would like to do is basically accomplish this result by doing the following:

EXEC msdb.dbo.sp_send_dbmail
@recipients= 'email1',     --email address from above query
@subject='Test email',
@body='You have X projects waiting'    -- where X is the COUNT() term

for each of the lines.

My understanding is that I can do it a little simply for each record if I use the cursor, but all the documents and results I found show that this is not a good strategy.

What is the best way to do something like this?

DECLARE @i int = 0

WHILE (@i < @count)
BEGIN
    SELECT @emailAddress = EmailApprover, ...
    FROM @YourTempResults
    WHERE RowNumber = (@i + 1) -- row number is 1-based

    EXEC msdb.dbo.sp_send_dbmail @recipients = @emailAddress, ...

    SET @i = @i + 1

Select SendPMMail(ProjectCode, EmailAddress, ProjectCount) from
(SELECT ProjectCodes.ProjectCode as ProjectCode, 
        COUNT(Projects.ProjectsID) as ProjectCount, 
        ProjectApprovers.EmailApprover as EmailAddress
   FROM Projects 
  INNER JOIN ProjectCodes
        ON Projects.ProjectCodesID=ProjectCodes.ProjectCodesID
  INNER JOIN ProjectApprovers
        ON Projects.ProjectCodesID=ProjectApprovers.ProjectCodesID
  WHERE ProjectApprovers.IsPrimaryApprover=1
  GROUP BY ProjectCodes.ProjectCode, ProjectApprovers.EmailApprover)
