Answer 1

Can I write a Query to filter date column which is equal to 1900-01-01 or greater than 2013-1-1 ?

Yes, you can, it's pretty much exactly as you phrased the question.

Something like this should do the trick:

select something from my_table
where date = '1900-01-01'
   or date > '2013-01-01'

If your condition is more complex than that, you can parenthesise the clause to keep it self-contained (no precedence rules mucking up your overall condition):

select something from my_table
where (date = '1900-01-01' or date > '2013-01-01')
  and blah blah blah

Answer 2

Try this,

select data from Table where date=' 1900-01-01'
union all
select data from Table where date >'2013-1-1'

Answer 3

In SQL Server,You can use DATEDIFF function for comparing date values.

    SELECT col1,col2,.. FROM YourTable WHERE DATEDIFF(dd,date,'1900-01-01') = 0;

    UNION ALL 

    SELECT col1,col2,.. FROM YourTable WHERE DATEDIFF(dd,date,'2013-01-01') > 0;
