    Unhappy

    Can we decode a already decoded statement?
    I have column which displays zeros by using NVL function for some rows . I want to display the same value for all rows for that column.


    this is the query

    create or replace view vw_post_to_treasury as
    (SELECT distinct
    ltrim(rtrim(substr(tc_line_rev_acct_no,1,5),'-'),'-')Fund,
    ltrim(rtrim(substr(tc_line_rev_Acct_no,7,4),'-'),'-')Org,
    ltrim(rtrim(substr(tc_line_rev_acct_no,12,5),'-'),'-')Account,
    ltrim(rtrim(substr(tc_line_rev_acct_no,17,3),'-'),'-')Program,
    to_date(v.tc_tran_date,'dd-MON-yy') Payin_date,
    (v.TOTAMTPD-(sum(nvl(p.pw_amount,0)))) Amount,
    decode(p.payin_prefix,' ',28,0,28,null,28,p.payin_prefix) Payin_prefix,
    --nvl(decode(p.pw_payin_no,' ',p.pw_payin_no,0,pw_payin_no,null,p.pw_payin_no,p.pw_payin_no),0) Payin_No,
    nvl(p.pw_payin_no,0) Payin_no, *****here is the problem.
    decode(p.pw_cr_deb_ind,' ','D',null,'D','D')Cr_deb_ind,
    decode(p.post_flag,' ','N',null,'N',p.post_flag)Post_flag,
    'one stop payins '||28||'-'||nvl(p.pw_payin_no,0)comments --decode(p.pw_payin_no,' ',p.pw_payin_no,null,p.pw_payin_no,0,p.pw_payin_no,p.pw_payin_no) comments
    from vw_payin_line v, payin_withdrawal p
    where v.tc_tran_date= p.pw_payin_date(+)
    and v.tc_line_rev_acct_no= p.pw_rev_acct_code(+)
    group by v.tc_line_rev_acct_no,v.tc_tran_date,v.totamtpd,
    p.payin_prefix,p.pw_payin_no,p.pw_cr_deb_ind,p.post_flag )

    Thanks Shestakov. In that example you gave (in the inner decode function )can we use a field_name instead of users.Users is just a string you gave but I want to display a column value there instead some other value.

    u can just little bit modify this example:
    in this example i used :
    -- internal decode and
    -- choice from different dields in decode

    I hope this is enough.

    select object_name,
    decode(object_type,
    'TABLE', 'This is table of schema :'|| decode(owner,'SYS','SYS DBA',owner),
    'INDEX', 'This index created : '||to_char(created),
    object_type)
    from all_objects
    ;
