Where are you going to "give a date"?

Do you mean instead of 2010?

That will not work, as YEAR(myColumn) returns an integer, so it needs another integer to be compared with, otherwise you get incompatible data type issues.

Need an answer? No, you need a question

The TSQL example below work since you are comparing apples with apples.

select * from xyz where year(created_on) < year('2012-01-01')

-- or

select * from xyz where created_on < '2012-01-01'

What is the datatype of "Create_on"?

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
