Emacs, searching for something that is seperated by a newline

I have some data files that end up having pesky erroneous lines. For example, in the following file:
data, A, 1, B, 2

data, A, 4, B,5
I want to get rid of the five comma only lines. What search string do I enter into emacs to find these?

Try this:
M-x flush-lines RET ^,$ RET
where RET means hit Return(or Enter) key. You can read this page for more detail.
