Hi
I have a database size which has around 230 tables and around 5 char/varchar columns / table. I need to change these fields into nchar/nvarchar. What would be the impact. Maybe some ballpark figure.
Is there some way I can get an accurate figure..
Please help

As a general rule, you can figure about 2 times the size of the original field, * number of rows * number of tables.
This will ballpark you i think. Remember, to check DBCC ShowContig after the change to ensure your indexes are not too fragmented.
