SELECT Temp.NoThread FROM (SELECT Top 10 NoThread FROM Thread ORDER BY Numero DESC) TempSo, in the result, I get all the keys that I need for the most recent 10 threads. However, based on those keys, I would now like to include a column for the count. Thread.NoThread have several occurences in the table. So, the result would include a column for the count having a value from 1 to x.
