Determine row size for table

Question

How to I determine the maximum row size for a table? I\'m looking for a tool or script that does this so I don\'t have to add up each column\'s size by hand.

Answer 1

Here is another query I got, but like Tomalak's it is broken because it doesn't take into account things like the overhead for variable length columns.

SELECT OBJECT_NAME (id) tablename
     , COUNT (1)        nr_columns
     , SUM (length)     maxrowlength
FROM   syscolumns
GROUP BY OBJECT_NAME (id)
ORDER BY OBJECT_NAME (id)
