SQLITE3 date and interval function

select< br /> ...
from 
 orders
where
 ...
 and o_orderdate  
Error: near line 4: near "'1995-03-01'": syntax error
 
Then, I modified some declarations, such as;
 
 
 
and o_orderdate 
This time the error is;
Error: near line 4: near " '3'": Syntax error
Unfortunately, the same technique does not work for the interval function, ie

and o_orderdate 
or

and o_orderdate 
even

and o_orderdate  
Still giving me a syntax error.
 
Maybe sqlite3 does not support the interval function or I missed its usage? 
 
Thank you very much

I want to know whether sqlite3 supports interval functions. PostgreSQL accepts the following statement, but sqlite3 cannot parse it;

select
 ...
from 
 orders
 where
 ...
 and o_orderdate 
Error: near line 4: near "'1995-03- 01'”: Syntax error
Then, I modified some statements, such as;

and o_orderdate 
This time the error is;
Error: Near line 4: Near "'3'": Syntax error
Unfortunately, the same The trick does not work for the interval function, that is

and o_orderdate 
Either

and o_orderdate 
even
 < p>
and o_orderdate 
It still gives me syntax errors.
