Execute a query foreach row from a result set. - sql

Question

I have a query that needs to be executed for each row in a result set. I understand that I need to do this with cursors, but I dont know how.
The first query contains customers with a specific condition, I need to retreive the Id:s from them.
The second query selects the latest activity from these customers.
Query 1
SELECT DISTINCT c.Name, c.Id
FROM Persons p
JOIN Customers c ON c.id = p.Customer_Id
WHERE C.State = 3 AND c.SalesPerson_Id ='A3160011-CAA6-E411-A83E-AC7BA1B90A6D' AND c.Id NOT IN
(
SELECT Distinct p.Customer_Id
FROM Activities a
JOIN Persons p
ON a.Person_Id = p.Id
WHERE a.[Type] IN (5,6) AND a.[Time] > getdate()-30 AND a.[Time] < getdate()
)
AND c.id NOT IN
(
SELECT
DISTINCT p.Customer_Id
FROM
Persons p
JOIN HtmlEmails he ON p.Id = he.UserId
JOIN ReportLog rl ON he.Id = rl.HtmlEmails_Id
WHERE rl.[Time] > getdate()-30 AND rl.[Time] < getdate())
Query 2
SELECT TOP 1 *
FROM(
SELECT TOP 1 c.Name AS 'CustomerName', c.Id AS 'CustomerId', a.[Time] AS 'LastActivity',(p.FirstName + ' ' + p.LastName) AS 'UserFullName' , 'Login' AS 'Type'
FROM Activities a
JOIN Persons p ON p.Id = a.Person_Id
JOIN Customers c ON p.Customer_Id = c.Id
WHERE a.[Type] IN (5,6) AND a.[Time] < getdate()-30
ORDER BY a.[Time] DESC
UNION
SELECT TOP 1 c.Name AS 'CustomerName', c.Id AS 'CustomerId', a.[Time] AS 'LastActivity',(p.FirstName + ' ' + p.LastName) AS 'UserFullName' , 'Email' AS 'Type'
FROM Activities a
JOIN HtmlEmails he ON a.TargetId = he.Id
JOIN ReportLog rl on he.Id = rl.HtmlEmails_Id
JOIN Persons p ON p.Id = a.Person_Id
JOIN Customers c ON p.Customer_Id = c.Id
WHERE a.[Time] < getdate()-30
ORDER BY a.[Time] DESC
)AS x
ORDER BY 'LastActivity' DESC
Thanks!
