SQL Case When Count Then value else value is not giving desired result

I have the folowing situation.

Table (example)

What I am trying is the folowing. When the Datetime value in the row of column OCTeamLastTime(datetime) is higher dan the current datetime CURRENT_TIMESTAMP. I want a Sql variable to be Now and else the value from OCTeamLastTime(datetime) as CanDoOC .

I am currently trying the folowing statement. But this gives me the result Now for every outcome.

SELECT OCTeamName,OCTeamID,OCTeamLastTime, 
    (CASE WHEN(SELECT COUNT(OCTeamID) FROM OCTable WHERE OCTeamLastTime >= CURRENT_TIMESTAMP AND OCTeamID = OCTeamID) > 0 THEN 'Now' ELSE OCTeamLastTime END) AS CanDoOC FROM OCTable

I want to use these results in a option list in php/html. Desired results based on above table:

<option data-subtext="Next OC: <?php echo $SelectOCTeam['CanDoOC']; ?>" value="<?php echo $SelectOCTeam['OCTeamID']; ?>"><?php echo $SelectOCTeam['OCTeamName']; ?></option>

It should create 5 options in this case. With Next OC: Now for the team with ID 1,3 and 5 and the OCTeamLastTime value for the other options.

Does anyone how to accomplish this? As what I did is not working and I cant think of any other way to make this work.

>Solution :

I believe that you just want the following query (without subquery)

SELECT OCTeamName,OCTeamID,OCTeamLastTime, 
    CASE WHEN OCTeamLastTime >= CURRENT_TIMESTAMP 
      THEN 'Now' 
      ELSE OCTeamLastTime 
      END AS CanDoOC 
FROM OCTable
