 Insert into SampleRevenue
 Values('Tom','Belt',6,2014,150)

 go

So like if i want to check the result for the current quarter . The output should be like below :

Note ( '.' in the table is just used for the formatting as without it the column layout was out of order)

Please help

Thanks in Advance
