SQL IF ELSE WITH MULTIPLE SELECT STATEMENT

I want to optimize these SQL queries using if-else but how I should use it? . if this query result contain 'ALL'

SELECT
bdsubcategory.subcategoryID as ID,
bdsubcategory.subcategoryName as Name
FROM
phonebook.newsms_subscription
INNER JOIN bdsubcategory ON bdsubcategory.subcategoryID = newsms_subscription.subcategoryID
INNER JOIN newsms_client ON newsms_subscription.clientID =newsms_client.clientID
INNER JOIN newsms_person ON newsms_subscription.personID = newsms_person.personID
WHERE
newsms_subscription.isActive = 1 AND
newsms_person.personID = '856'

Then i want to query this

SELECT
bdsubcategory.subcategoryID as ID,
bdsubcategory.subcategoryName as Name
FROM
phonebook.newsms_subscription
INNER JOIN bdsubcategory ON bdsubcategory.subcategoryID = newsms_subscription.subcategoryID
INNER JOIN newsms_person ON newsms_subscription.personID = newsms_person.personID
WHERE
newsms_subscription.isActive = 1
GROUP BY subcategoryName
ORDER BY subcategoryName

otherwise take query1 result .
