Multiple parameters one row for each record

Question

I have this query I want the user to be able to allow the user to enter multiple MATL_CODE_MOD as a parameters, the problem is that the GURMAIL table have multiple records one for each GURMAIL_MATL_CODE_MOD, so it will give me duplicates.. How I can code this, so I can allow the user to enter multiple MATL_CODE_MOD codes, and have only one row for each record...
and GURMAIL_MATL_CODE_MOD in ('8IBC','8IBD')
select
spriden_id,        
spbpers_name_suffix   name_suffix,
spbpers_name_prefix   name_prefix,
spriden_last_name     last_name,
spriden_first_name    first_name,
spriden_mi            mi,
srbrecr_term_code,
srbrecr_majr_code,
srbrecr_program_1,
saturn_midd.utlq.f_matl_code_type(srbrecr_pidm)
FROM
saturn.srbrecr,
saturn.spriden,
saturn.spbpers,
SATURN.SPRADDR,
general.gurmail
WHERE
spriden_pidm = srbrecr_pidm
and gurmail_pidm = spriden_pidm
AND spriden_pidm = spraddr_pidm 
--and srbrecr_term_code = decode(p_term  ,'%',SRBRECR_TERM_CODE,p_term)
and spbpers_pidm = spriden_pidm
and spriden_change_ind is null
--and gurmail_matl_code_mod
and SRBRECR_PROGRAM_1 = 'CMQ'
and GURMAIL_MATL_CODE_MOD in ('8IBC','8IBD')
--AND SPRADDR_ATYP_CODE = 'CM'
AND SPRADDR_STREET_LINE1 IS NOT NULL;

Hi,
SELECT DISTINCT ...will keep duplicate rows out of the result set.
Depending on your data, another possibility might be to not join the table that contains GURMAIL_MATL_CODE_MOD. Do an EXISTS sub-query on that table instead.
If you need more help, post some sample data from all the tables, and the results you want from that data.
Simplify, if possible, You can probably post a problem with 2 or 3 tables, each with 2 or 3 columns, that will have the same answer.
