=     CONVERT(VARCHAR(20),CAST(\'Feb 15 2012  7:00:00:000PM\' AS DATETIME),101)

Answer 1

Use 112 CONVERT's format

select * 
from sampleTable 
where 
  CONVERT(VARCHAR(20),DateCreated,112) 
=     CONVERT(VARCHAR(20),CAST('Feb 15 2012  7:00:00:000PM' AS DATETIME),112)

or

if your sql server version 2008+ use DATE type

select * from sampleTable 
where CONVERT(DATE,DateCreated) 
=     CONVERT(DATE,CAST('Feb 15 2012  7:00:00:000PM' AS DATETIME))
