Subject: Number of Columns in a Table & SQL Performance ?


Folks
 
Does the number of columns in a table affect the performance of SELECT/INSERT/UPDATE in OLTP Transactions.
If so, why?
 
NOTE - Merge of 2 existing tables each has 200 columns approx into a single Table is being planned..
 
Thanks in Advance
 
Vivek
