Collecting stats on unused column - forum topic by barani_sachin

Hi All,
    Does collecting stats on unused columns in anyway influence the execution plan.
Ex

sel t1.* from table1 t1 join table2 t2 on t1.col1 = t2.col1

lets say if i collect stats on col2, col3 and so on in both the tables.
Except for the unnecessary overhead for collecting the stats does it in anyways impact any other thing??  Because i keep getting advice from ma senior colleagues that it will have an impact on query execution plan.
If not now, was it the case in any previous versions?
