This is a simple question and I can\'t seem to think of a solution.
I have this defined in my stored procedure:
@communityDesc varchar(255) = NULL
You can do this by splitting your string using a split function provided here. The function returns a table having a single column which holds your tokens (i.e. 'aaa', 'bbb' ...).
Your query should look like this:
-- get the splits
SELECT Name INTO #someTemp
FROM dbo.splitstring(@communityDesc)
-- get data where area in within description
SELECT 1
FROM yourTable T
WHERE EXISTS (SELECT 1 FROM #someTemp tmp WHERE T.Area = tmp.Name)
