I created the column frfpost_short but now I am having trouble making the column usable in a query.
select t.corridor,
s.corridor_code_rb,t.roadway,s.SVYLENG2012,
round(cast(t.frfpost as float),3)) as frfpost_short,
s.FRFPOST,s.BEG_GN
from SEC_FILE_IMPORT_2014 t,NORTH_VAN_DATA_VIEW_MOD_032015 s,
where frfpost_short = s.FRFPOST -- This line is causing problems
-- I would like to make frfpost_short queryable
and t.corridor = s.CORRIDOR_CODE
order by 1
Use a subquery or repeat the expression. Aliases defined in the select are not available in the where:
select t.corridor,
s.corridor_code_rb,t.roadway, s.SVYLENG2012,
round(cast(t.frfpost as float), 3) as frfpost_short,
s.FRFPOST, s.BEG_GN
from SEC_FILE_IMPORT_2014 t join
NORTH_VAN_DATA_VIEW_MOD_032015 s
on round(cast(t.frfpost as float), 3) = s.FRFPOST and
t.corridor = s.CORRIDOR_CODE
order by 1
I fixed your query. In particular, learn to use explicit join syntax.
You can't use aliases in where clause, you need to use below solution
select t.corridor,
s.corridor_code_rb,t.roadway,s.SVYLENG2012,
round(cast(t.frfpost as float),3)) as frfpost_short,
s.FRFPOST,s.BEG_GN
from SEC_FILE_IMPORT_2014 t,NORTH_VAN_DATA_VIEW_MOD_032015 s,
where round(cast(t.frfpost as float),3)) = s.FRFPOST
and t.corridor = s.CORRIDOR_CODE
order by 1

I've the following subquery in an sql query:
(
SELECT ID_PLAN, ID_CURSO, NEDICION, NOMBRE AS NOMBREUNIDAD FROM ASISTEN, ALUMNOS, UNIDADES
WHERE ASISTEN.COD = ALUMNOS.COD AND UNIDADES.IDESTRUCTURA = ALUMNOS.IDESTRUCTURA
AND UNIDADES.CDUNDORG = ALUMNOS.CDUNDORG
AND UPPER(TRANSLATE(UNIDADES.NOMBRE, 'áéíóúÁÉÍÓÚ', 'aeiouAEIOU')) LIKE '%CONSEJERIA%'
GROUP BY ID_PLAN, ID_CURSO, NEDICION) ASIS
Problem I have I believe lies in that both table ALUMNOS and UNIDADES have a column named 'NOMBRE' so if I attempt to execute the query I obtain:
00000 - "column ambiguously defined"
To avoid that I thought about changing NOMBRE AS NOMBREUNIDAD to:
UNIDADES.NOMBRE AS NOMBREUNIDAD
But if I do that I get a:
00000 - "not a GROUP BY expression"
So, I don't know what to do so that subquery executes properly.
What should I change to properly execute query without changing the column name?
Aliases are pretty useful, if you use them. The simplify queries and make them easier to read and maintain. I'd suggest you to do so, as it'll also help query to work because Oracle doesn't know which table you actually meant when you selected those 4 columns - which tables do they belong to?
This is just a guess as I don't know your tables so you'll have to fix it yourself. Also, I literally JOINed tables; try to avoid comma-separating them in FROM clause and doing join in WHERE clause as it is supposed to filter data.
GROUP BY, as already commented, is probably useless. If you wanted to fetch distinct set of values, then use appropriate keyword: distinct.
SELECT DISTINCT n.id_plan,
s.id_curso,
u.nedicion,
u.nombre
FROM asisten n
JOIN alumnos s ON n.cod = s.cod
JOIN unidades u
ON u.idestructura = s.idestructura
AND u.cdundorg = s.cdundorg
WHERE UPPER (TRANSLATE (u.nombre, 'áéíóúÁÉÍÓÚ', 'aeiouAEIOU')) LIKE '%CONSEJERIA%'
I managed to solve my problem:
(
SELECT ID_PLAN, ID_CURSO, NEDICION, UNIDADES.NOMBRE AS NOMBREUNIDAD
FROM ASISTEN, ALUMNOS, UNIDADES
WHERE ASISTEN.COD = ALUMNOS.COD AND UNIDADES.IDESTRUCTURA = ALUMNOS.IDESTRUCTURA
AND UNIDADES.CDUNDORG = ALUMNOS.CDUNDORG
AND UPPER(TRANSLATE(UNIDADES.NOMBRE, 'áéíóúÁÉÍÓÚ', 'aeiouAEIOU')) LIKE '%CONSEJERIA%'
GROUP BY UNIDADES.NOMBRE,ID_PLAN, ID_CURSO, NEDICION
)
I have a SQL query where I am trying to replace null results with zero. My code is producing an error
[1]: ORA-00923: FROM keyword not found where expected
I am using an Oracle Database.
Select service_sub_type_descr,
nvl('Single-occupancy',0) as 'Single-occupancy',
nvl('Multi-occupancy',0) as 'Multi-occupancy'
From
(select s.service_sub_type_descr as service_sub_type_descr, ch.claim_id,nvl(ci.item_paid_amt,0) as item_paid_amt
from table_1 ch, table_" ci, table_3 s, table_4 ppd
where ch.claim_id = ci.claim_id and ci.service_type_id = s.service_type_id
and ci.service_sub_type_id = s.service_sub_type_id and ch.policy_no = ppd.policy_no)
Pivot (
count(distinct claim_id), sum(item_paid_amt) as paid_amount For service_sub_type_descr IN ('Single-occupancy', 'Multi-occupancy')
)
This expression:
nvl('Single-occupancy',0) as 'Single-occupancy',
is using an Oracle bespoke function to say: If the value of the string Single-occupancy' is not null then return the number 0.
That logic doesn't really make sense. The string value is never null. And, the return value is sometimes a string and sometimes a number. This should generate a type-conversion error, because the first value cannot be converted to a number.
I think you intend:
coalesce("Single-occupancy", 0) as "Single-occupancy",
The double quotes are used to quote identifiers, so this refers to the column called Single-occupancy.
All that said, fix your data model. Don't have identifiers that need to be quoted. You might not have control in the source data but you definitely have control within your query:
coalesce("Single-occupancy", 0) as Single_occupancy,
EDIT:
Just write the query using conditional aggregation and proper JOINs:
select s.service_sub_type_descr, ch.claim_id,
sum(case when service_sub_type_descr = 'Single-occupancy' then item_paid_amt else 0 end) as single_occupancy,
sum(case when service_sub_type_descr = 'Multi-occupancy' then item_paid_amt else 0 end) as multi_occupancy
from table_1 ch join
table_" ci
on ch.claim_id = ci.claim_id join
table_3 s
on ci.service_type_id = s.service_type_id join
table_4 ppd
on ch.policy_no = ppd.policy_no
group by s.service_sub_type_descr, ch.claim_id;
Much simpler in my opinion.
for column aliases, you have to use double quotes !
don't use
as 'Single-occupancy'
but :
as "Single-occupancy",

I've used aliases before in select statements so I'm confused on why I am getting an error for this. Does it work differently in this situation?
From the documentation (emphasis added):
You can use a column alias, c_alias, to label the immediately
preceding expression in the select list so that the column is
displayed with a new heading. The alias effectively renames the select
list item for the duration of the query. The alias can be used in the
ORDER BY clause, but not other clauses in the query.
So you can't refer to the alias in the where clause, where at the moment you have:
...
AND (account_amt NOT BETWEEN ...
...
The alias isn't valid at that point, so it's looking for a column with that name in one of the tables, and doesn't find one. It's fine in the order by though.
You either need to replace the alias with the repeated decode statement, or possibly use a subquery and then refer to the alias in a where clause in an outer query, but that might end up being less efficient depending on how selective your other conditions are.
Oracle runs the select query in the order below:
FROM clause
WHERE clause
GROUP BY clause
HAVING clause
SELECT clause
ORDER BY clause
Based on the above, you can see that when you are in the WHERE part, the alias has not yet been created. If you would like to use results from the SELECT part, you can do that by modifying your query like this:
WITH q AS
(
-- Your query without the extra AND
)
SELECT *
FROM q
WHERE --put your check here
This way you will already have the alias available when you reach the WHERE part.
Hope this helps! :)

I have the following sql syntax that I used in my database query (SQL Server)
SELECT Nieuwsbrief.ID
, Nieuwsbrief.Titel
, Nieuwsbrief.Brief
, Nieuwsbrief.NieuwsbriefTypeCode
, (SELECT COUNT(*) AS Expr1
FROM NieuwsbriefCommentaar
WHERE (Nieuwsbrief.ID = NieuwsbriefCommentaar.NieuwsbriefID
AND NieuwsbriefCommentaar.Goedgekeurd = 1)) AS AantalCommentaren
FROM Nieuwsbrief
I'm changing now to sql-server-ce (compact edition) which won't allow me to have subqueries like this. Proposed solution : inner join. But as I only need a count of the subtable 'NieuwsbriefCommentaar', I have to use a 'group by' clause on my base table attributes to avoid doubles in the result set.
However the 'Nieuwbrief.Brief' attribute is of datatype 'text'. Group by clauses are not allowed on 'text' datatype in sql-server-ce. 'Text' datatype is deprecated, but sql-server-ce doesn't support 'nvarchar(max)' yet...
Any idea how to solve this? Thx for your help.
I think that the solution could be easier. I don't know exactly how is your metadata but I think that this code could fit your requirements by simply using LEFT JOIN.
SELECT Nieuwsbrief.ID
, Nieuwsbrief.Titel
, Nieuwsbrief.Brief
, Nieuwsbrief.NieuwsbriefTypeCode
, COUNT(NieuwsbriefCommentaar.NieuwsbriefID) AS AantalCommentaren
FROM Nieuwsbrief
LEFT JOIN NieuwsbriefCommentaar ON (Nieuwsbrief.ID = NieuwsbriefCommentaar.NieuwsbriefID)
WHERE NieuwsbriefCommentaar.Goedgekeurd = 1
Edited: 2ndOption
SELECT N.ID, N.Titel, N.Brief, N.NieuwsbriefTypeCode, G.AantalCommentaren FROM Nieuwsbrief as N LEFT JOIN (SELECT NieuwsbriefID, COUNT(*) AS AantalCommentaren FROM NieuwsbriefCommentaar GROUP BY NieuwsbriefID) AS G ON (N.ID = G.NieuwsbriefID)
Please, let me know if this code works in order to find out another workaround..
