DAL Dataset showing all the column


I follow the tutorial and create DAL with Dataset. I created a Table Adapter with many column, but when i Call a simple Get for 2 column only. The system display 2 column and the rest column with empty data.

My question is that will this affect the performance? because i only need 2 column.

example: Table with 40 column define in Dataset in DAL. I have GetMember from Dataset with 40 column, some request only 1 column (with 39 empty), some request 22 column (with 18 empty column). Will this affact the performance?

Should i create a seperate DatasetAllColumn, Dataset1Column, Dataset22Column ?? so system only return exact column i need. and hofully the performance is optimized to it best.
