Actually this is not a performance issue bcos when Oracle fetches rows for a select it does in with implicit cursor
which goes row by row not column by column. Even if we mention a single col it fetches the whole row.

Gurus correct me I am wrong..

Subject: Is this a performance issue?

Gurus,

 I'm wondering if it's a performance issue if i select all the columns from  a table even if you don't require.

 Let say I have a table which has about 50 columns in it and i need to get  values for only 5-10 columns. So, instead of selecting only these columns  I select *.

 Any idea if that screws up my performance?
