I would like to write a query
Select col1, col2 
from table 
where col1 = 'blah' or 'blah2' or 'blah3' 
  and col2 = 'blah' or 'blah2' or 'blah3'
I am used to writing them like this for a SINGLE option
select 
    col1, col2 
from 
    table 
where 
    col1 = :col1 and col2 = :col2
Parameters.AddWithValue(":col1", 'blah')
Parameters.AddWithValue(":col2", 'blah')
Now I want to add several options with OR between them and obviously the above code wont work. The SQL is for SQLite. Can anyone suggest how I could do this? I may potential have more then 3 different values for each parameter. I have tried searching but the answer is elusive.
