Home -> Community -> Mailing Lists -> Oracle-L -> Re:Row Length
Try using
select avg(nvl(vsize(<column_name>),1)+nvl(vsize(<column_name>),1)+.....) from <table_name>;
And yes columns that have a null value do mess things up.

How is the the Length of any ROW in a Table/Index Manually Calculated ? NOTE - Corresponding Table's Feild Definitions are known
Do Data Values within the Fields / Null cause Different ROW Lengths ?
NOTE I do know about Feild AVG_ROW_LEN of sys.dba_tables which is populated on ANALYZE
