How do I copy column A data to column B?

I am using MS-SQL 2005 and trying to copy Entire COlumn A to new column which is columnB.
I used this query

Update BoardTable Set ColumnA=ColumnB
and it's now working. After I did this query, both column was filled with NULL value.
Help please.
Thank you

I hope you did a backup first, or wrapped it in a transaction then rolled it back. The problem is the order in which you named the columns. It should be:
Update BoardTable Set ColumnB=ColumnA

Thank you.
I have another question. How do I insert certain columns from different table?

Select (BoardTitle,BoardName) into NewTable From BoardTable where boardID>5 and boardid<10

I want to do something like top query. Is it possible, if it's possible then let me know. Thank you
INSERT INTO newTable(BoardTitle, BoardName) SELECT BoardTitle, BoardName FROM BoardTable
WHERE boardID > 5 and boardid < 10
