ORA-00904 error with create or replace view

[Curtiosity]

I have done a create or replace view called creditcard1. If I do a "select * from creditcard1" it retrieves the data just fine. If I try to do a statement where I am listing the column names it doesn't recognize them.

create or replace view creditcard1 as
select
pidm
,tbraccd_term_c ode as "Term"
,tbraccd_detail _code as "Detail_Cod e"
,tbbdetc_desc as "Detc_Desc"
,tbraccd_tran_n umber as "Tran_Numbe r"
,DECODE(tbbdetc _type_ind, 'C', tbraccd_amount, 0.00) as "Charge_Amo unt"
,DECODE(tbbdetc _type_ind, 'P', tbraccd_amount, 0.00) as "Payment_Amount "
,tbraccd_activi ty_date as "Activity_D ate"
,tbraccd_desc as "TBRACCD_DE SC1"
,MAX (tbracct.TBRACC T_DETC_EFF_DATE )
KEEP (DENSE_RANK LAST order by (tbracct.TBRACC T_DETC_EFF_DATE )) max_detc_eff_da te
from creditcard, tbraccd, tbbdetc, tbracct
where pidm = tbraccd_pidm
and tbr_chg_tran_nu m = tbraccd_tran_nu mber
and tbbdetc_detail_ code = tbraccd_detail_ code
and pidm = '20'
and tbraccd_detail_ code = tbracct_detail_ code
group by
pidm
,tbraccd_term_c ode
,tbraccd_detail _code
,tbbdetc_desc
,tbraccd_tran_n umber
,DECODE(tbbdetc _type_ind, 'C', tbraccd_amount, 0.00)
,DECODE(tbbdetc _type_ind, 'P', tbraccd_amount, 0.00)
,tbraccd_activi ty_date
,tbraccd_desc
order by pidm, tbraccd_tran_nu mber

Then I try to run:

create or replace view creditcard2 as
select
creditcard1.pid m
,creditcard1.Te rm
,creditcard1.De tail_Code
,creditcard1.De tc_Desc
,creditcard1.Tr an_Number
,creditcard1.Ch arge_Amount
,creditcard1.Pa yment_Amount
,creditcard1.Ac tivity_Date
,creditcard1.TB RACCD_DESC1
,creditcard1.ma x_detc_eff_date
,tbracct_b_fund _code as "Charge_Fun d"
,tbracct_b_orgn _code as "Charge_Org n"
,tbracct_b_acct _code as "Charge_Acc t"
from creditcard1, tbracct
where creditcard1.Det ail_Code = tbracct_detail_ code
and creditcard1.max _detc_eff_date = tbracct_detc_ef f_date

and get this error message:

ORA-00904: "CREDITCARD1"." DETAIL_CODE":in valid identifier

I have checked the spelling - in fact I just did a cut and paste so there wouldn't be spelling errors. When I do the "select * from creditcard1" it lists the column name of "Detail_Cod e" - the same column that the error message says doesn't exist. If I try just a select statement instead of "create or replace view creditcard2 as", I get the same error. The creditcard1 view is coming from a view I did called creditcard and it didn't have any problems recognizing the column names from the original view of creditcard.

If I comment out the where clause, it just gives the same error on a different column name - if I comment out that column name, then it errors on the next column name.

I am using SQL through TOAD against an Oracle 9i database.

Any ideas on why it won't recognize the columns from the view I created?

I am doing the creditcard2 view to pull in additional data for tbracct_b_fund_ code, tbracct_b_orgn_ code and tbracct_b_acct_ code because I was getting multiple rows in the results that I didn't want. In the table TBRACCT there can be multiple rows per tbracct_detail_ code. I only want to choose data from the row with the most recent tbracct_detc_ef f_date. The MAX statement does that, but if I also select tbracct_b_fund_ code in the same statement, it pulls a row for each different value that exists in tbracct_b_fund_ code (even if the tbracct_detc_ef f_date is not the most recent). So - if there was some way to code the creditcard1 view to also include tbracct_b_fund_ code, tbracct_b_orgn_ code and tbracct_b_acct_ code without getting the duplicate data that would be helpful also.

Thanks,

Quotes around alias names

I found the answer to my problem from another source, but thought I would post it here in case it could benefit someone else:

"I think the problem is in your use of explicit capitalization in the aliases for the columns of your views. Once you put double quotes around a column alias you must put double quotes around any reference to it and match the capitalization exactly from then on. So you must change all your WHERE clauses and any GROUP BYs or ORDER BYs... As a matter of coding style I would recommend leaving off all the double quotes; then by default the Oracle SQL engine will promote all references to upper case making coding much easier."
