Your query should work as 0 is an integer, the data from 'Number1' will be converted to integer

or else if you want explicit conversion

select * from table where cast(Number1 as bigint )  > 0

-- Here's how you select it as an integer..
select CAST(Number1 as int)  
from table

Depending on your situation you'll want to validate whether Number1 really is an integer, either because it has decimal values (12.3) or it's a string ('banana')

-- This will weed out all of the non-numeric values.
select CAST(Number1 as int)  
from table
where ISNUMERIC(Number1) = 1


-- Then you'll have to decide if you want to weed out the decimal values, or round them.
