What do you mean, concatenate rows? Specific counts, or a however many meet some criteria?

Showing some sample data and DDL would help.

As a hint, a cross tab or PIVOT might be what you need.

Some people mean "concatenate" and some people mean "pivot". A before and after example of what you'd like to do would be really helpful in helping you.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

SELECT p1.CategoryId,

( SELECT ProductName + ','

FROM Northwind.dbo.Products p2

WHERE p2.CategoryId = p1.CategoryId

ORDER BY ProductName

FOR XML PATH('') ) AS Products

FROM Northwind.dbo.Products p1

GROUP BY CategoryId ;

i prefer using For XML in this scenario for more inf.
