Multiple columns for the rows

Question

Hello everyone,
Can anyone give me a logic in the below scenario.
Table A
Col1 Col2 Col3
Peter 01-jan-2009 1000
Peter 7-mar-2009 1000
Peter 13-dec-2009 1000
i need a sql which displays all the data in a single row in such a way that
1) if col2 month is jan, then the column heading should be "January" and value should be Jan
2) if col2 month is mar, then the column heading should be "Marchh" and value should be Mar
3) if col2 month is dec, then the column heading should be "December" and value should be Dec
Thank you in advance.
