Collecting statistics - forum topic by mayya@teradataforum

Hi,
In my query, I am using set operator(minus) between two tables say A & B.
Select ...... 33 columns..... from A
minus
select ...... 33 columns..... from B
To enhance the performance of the query, is it recommended to collect statistics on all 33 columns of A & B tables since collecting statistics is resource consuming activity, i want to make sure that collecting statistics should not become dis-advantage here..
