Question

I am trying to use the following query in SQL Server

SELECT [AL].[Subscriptions].Id,
       [AL].[Subscriptions].name,
       [AL].[Subscriptions].description,
       [AL].[Subscriptions].price,
       [AL].[Subscriptions].iconFileName,
       IIf(a.expiryDate > Now(), 'TRUE', 'FALSE') AS isSubsByUser
FROM   [AL].[Subscriptions]
       LEFT JOIN (SELECT *
                  FROM   [AL].[UserSubscriptions]
                  WHERE  userId = 13259) AS a
         ON Subscriptions.Id = a.itemid; 

but always get the error

Error in list of function arguments: ‘>’ not recognized.
Unable to parse query text.

How do I resolve it?

Like Martin Smith said you need to use a case statement. Also it looks like you are only using a couple of fields in the derived table therefor I would suggest not using *. I put a example below.

   SELECT [AL].[Subscriptions].Id,
        [AL].[Subscriptions].name,
        [AL].[Subscriptions].description,
        [AL].[Subscriptions].price,
        [AL].[Subscriptions].iconFileName,
        case when a.expiryDate > GetDate() then 'TRUE' else 'FALSE' end AS isSubsByUser
   FROM   [AL].[Subscriptions]
   LEFT JOIN (SELECT expiryDate, itemid 
              FROM   [AL].[UserSubscriptions]
              WHERE  userId = 13259) AS a
     ON Subscriptions.Id = a.itemid;
