Flexible sql

Question

Hi All,
I have a table which I am using in a lookup in informatica.
select out1, out2, out3
from rule_table
where in1 = '100'
in2 = '1'
in3 = '155';
OK the above will return values if we have a direct hit.
e.g. rule table
inputs outputs
in1     in2     in3          out1     out2     out3     out4     out5
100     1     null      IE22     371003     970                              
100     1     +++     IE22     700101          X     IE2000                    
100     1     155     IE92     700101          X                         
However if I go in with 100,1,98 then it should pick up the row 2 as '+' is a placeholder for all in3 values that are not null or defined.
How do I do this in sql?

Sorry Guys for being vague,
CREATE TABLE FHMR_MAPPING_RULE

insert into cdhud.fhmr_mapping_rule values (3,1,1,

insert into cdhud.fhmr_mapping_rule values (4,1,1,

Please change current date (db2) for sysdate.
Then
select * from (select fhmr_id,fhmr_input_value1, fhmr_input_value2, fhmr_input_value3,fhmr_output_value1, fhmr_output_value2, fhmr_output_value3,
rank() over (order by case when fhmr_input_value3 = '+++' then 1 else 0 end desc) as rn
from cdhud.fhmr_mapping_rule
where fhmr_input_value1 = '100'
and fhmr_input_value2 = '1'
and fhmr_input_value3 = '155';
The above gives us 1 row.
