I'm having an issue using a column alias for a join in a cte. Invalid column name on the line with RowNumber2 >= (t1.RowNumber - 20) Anyone have a suggestion? Thanks..
DECLARE #latestDate Date = dbo.LatestDateWithPricingVolCountOver4k()
;WITH AllSymbsAndDates AS
(
SELECT
ROW_NUMBER() OVER (PARTITION BY Symbol ORDER BY TradingDate) AS RowNumber,
Symbol, TradingDate
FROM tblSymbolsMain
CROSS JOIN tblTradingDays
WHERE TradingDate <= #latestDate
),
SymbsDatesGrouped AS
(
SELECT * FROM
(
SELECT
t1.Symbol, t1.TradingDate, t2.TradingDate AS TradingDate2, t1.RowNumber,
t2.RowNumber AS RowNumber2
FROM AllSymbsAndDates t1
JOIN AllSymbsAndDates t2 ON t1.Symbol = t2.Symbol
AND RowNumber2 >= (t1.RowNumber - 20)
) t
)
SELECT
Symbol, TradingDate, TradingDate2, RowNumber, RowNumber2
FROM
SymbsDatesGrouped
ORDER BY
Symbol, TradingDate, TradingDate2
You can't reference a column alias in the WHERE or JOIN clauses - actually the only clause where you can reference an alias from the SELECT list is either in the ORDER BY (or in an outer scope, e.g. selecting from a subquery or CTE).
In this case, the solution is pretty trivial. Why not just say:
AND t2.RowNumber >= (t1.RowNumber - 20)
?

I want to create calculated table that will summarize In_Force Premium from existing table fact_Premium.
How can I filter the result by saying:
TODAY() has to be between `fact_Premium[EffectiveDate]` and (SELECT TOP 1 fact_Premium[ExpirationDate] ORDE BY QuoteID DESC)
In SQL I'd do that like this:
`WHERE CONVERT(date, getdate()) between CONVERT(date, tblQuotes.EffectiveDate)
and (
select top 1 q2.ExpirationDate
from Table2 Q2
where q2.ControlNo = Table1.controlno
order by quoteid` desc
)
Here is my DAX statement so far:
In_Force Premium =
FILTER(
ADDCOLUMNS(
SUMMARIZE(
//Grouping necessary columns
fact_Premium,
fact_Premium[QuoteID],
fact_Premium[Division],
fact_Premium[Office],
dim_Company[CompanyGUID],
fact_Premium[LineGUID],
fact_Premium[ProducerGUID],
fact_Premium[StateID],
fact_Premium[ExpirationDate]
),
"Premium", CALCULATE(
SUM(fact_Premium[Premium])
),
"ControlNo", CALCULATE(
DISTINCTCOUNT(fact_Premium[ControlNo])
)
), // Here I need to make sure TODAY() falls between fact_Premium[EffectiveDate] and (SELECT TOP 1 fact_Premium[ExpirationDate] ORDE BY QuoteID DESC)
)
Also, what would be more efficient way, to create calculated table from fact_Premium or create same table using sql statement (--> Get Data--> SQL Server) ?
There are 2 potential ways in T-SQL to get the next effective date. One is to use LEAD() and another is to use an APPLY operator. As there are few facts to work with here are samples:
select *
from (
select *
, lead(EffectiveDate) over(partition by CompanyGUID order by quoteid desc) as NextEffectiveDate
from Table1
join Table2 on ...
) d
or
select table1.*, oa.NextEffectiveDate
from Table1
outer apply (
select top(1) q2.ExpirationDate AS NextEffectiveDate
from Table2 Q2
where q2.ControlNo = Table1.controlno
order by quoteid desc
) oa
nb. an outer apply is a little similar to a left join in that it will allow rows with a NULL to be returned by the query, if that is not needed than use cross apply instead.
In both these approaches you may refer to NextEffectiveDate in a final where clause, but I would prefer to avoid using the convert function if that is feasible (this depends on the data).
I have 3 tables:
with current_exclusive as(
select id_station, area_type,
count(*) as total_entries
from c1169.data_cashier
where id_station IN(2439,2441,2443,2445,2447,2449) and date >= '2017-10-30' and date <= '2017-12-30'
group by id_station, area_type
), current_table as(
select id_station, area_type,
sum(total_time) filter (where previous_status = 1) as total_time
from c1169.data_table
where id_station IN(2439,2441,2443,2445,2447,2449) and date >= '2017-10-30' and date < '2017-12-30'
group by id_station, area_type
), current_cashier as(
select id_station, area_type,
sum(1) as total_transactions
from c1169.data_cashier
where id_station IN(2439,2441,2443,2445,2447,2449) and date >= '2017-10-30' and date < '2017-12-30'
group by id_station, area_type
)
select *
from current_exclusive
full join current_table on current_exclusive.id_station = current_table.id_station and current_exclusive.area_type = current_table.area_type
full join current_cashier on current_exclusive.id_station = current_cashier.id_station and current_exclusive.area_type = current_cashier.area_type
and the result is:
but my expected result is:
Are there any way to select * and show the expected result? Because when I do full join then id_station and area_type can be null in some tables, so it very hard to choose which column is not null.
Like: select case id_station is not null then id_station else id_station1 end, but I have up to 10 tables so can not do in select case
Use USING, per the documentation:
USING ( join_column [, ...] )
A clause of the form USING ( a, b, ... ) is shorthand for ON left_table.a = right_table.a AND left_table.b = right_table.b .... Also, USING implies that only one of each pair of equivalent columns will be included in the join output, not both.
select *
from current_exclusive
full join current_table using (id_station, area_type)
full join current_cashier using (id_station, area_type)
You cannot accomplish anything if you insist on using select *, since you are getting the values from different tables.
The option you have is to include a COALESCE block which gives you the first non-null value from the list of columns.
So, you could use.
select COALESCE( current_exclusive.id_station, current_table.id_station, current_cashier.id_station ) as id_station ,
COALESCE( current_exclusive.area_type , current_table.area_type, current_cashier.area_type ) as area_type ,.....
...
from current_exclusive
full join current_table..

I have this query, where I want to return zero values instead of null ones.
create view ct as
select userid, coalerse(count(tweets), 0) as nooftweets, coalerse(count(distinct mention), 0) as mention
from (
select t.user_id as userid, t.id as tweets, m.mentionedusers_id as mention, row_number() over (partition by m.tweet_id order by m.mentionedusers_id
) rn
from "tweet_mentUsers" m right join tweet t on m.tweet_id = t.id where text like '#%') a where rn <= 2 group by 1
However I get this error message:
ERROR: function coalerse(bigint, integer) does not exist
LINE 2: select userid, coalerse(nooftweets, 0), coalerse(mention, 0)...
^
HINT: No function matches the given name and argument types. You might need to add explicit type casts.
Do you have any idea?
I think the COALESCE function will do what you want.
create view ct as
select userid, coalesce(count(tweets), 0) as nooftweets, coalesce(count(distinct mention), 0) as mention
from (
select t.user_id as userid, t.id as tweets, m.mentionedusers_id as mention, row_number() over (partition by m.tweet_id order by m.mentionedusers_id

that i miss something ? or that could be worogn using an alias in subquery where clause in oracle database ?
You can use an identifier defined in an external query in only one level deep queries. You have to rethink your strategy. My suggestion is to remove the subquery from the select list and put it in the FROM clause. And add another rownumber column like this:
(SELECT
ID_PEGAWAI,
CONCAT(TO_CHAR(abs(sysdate - TO_DATE(TMT_JABATAN))/360,'9,999,999.9'),' TAHUN') MASA_KERJA,
ROW_NUMBER() OVER (PARTITION BY ID_PEGAWAI ORDER BY TMT_JABATAN DESC) rownumber
FROM SIMPEG_JABATAN) xxx
And join like:
ON ANGGARAN.SIMPEG_PEGAWAI = xxx.ID_PEGAWAI
Then in the where clause you can do simply:
WHERE
....
AND xxx.rownumber = 1

Oracle does not support columns aliases in WHERE clauses (or similar situations like here). You have to name the column again (by its original name).
select dummy as kode from dual where kode = 'X'
> ORA-00904: "KODE": invalid identifier
You need to assign an alias in the level below to use it in a query (I haven't checked the syntax and workability of your query, just changed the part which is essential to answer your question):
SELECT

TMP.NAMA,
TMP.NIP,

I have the following Inline Table-Valued Function:
SELECT Locations.LocationId,
dbo.Search_GetSuitability(#SearchPreferences,
Score.FieldA, Score.FieldB, Score.FieldC) AS OverallSuitabilityScore,
RANK() OVER (ORDER BY OverallSuitabilityScore) AS OverallSuitabilityRank
FROM dbo.LocationsView Locations
INNER JOIN dbo.LocationScores Score ON Locations.LocationId = Score.LocationId
WHERE Locations.CityId = #LocationId
That RANK() line is giving me an error:
Invalid column name 'OverallSuitabilityScore'.
The function dbo.Search_GetSuitability is a scalar-function which returns a DECIMAL(8,5). I need to assign a rank to each row based on that value.
The only way i can get the above to work is to add the scalar function call in the ORDER BY part again - which is silly. I have about 5 of these scalar function calls and i need seperate RANK() values for each.
What can i do? Can i use a Common Table Expression (CTE) ?
Yep, you can't reference a column alias in the SELECT clause. The CTE sounds good though. Here's an example
WITH Score as
(
select Score.LocationId, Score.FieldA, Score.FieldB, Score.FieldC,
dbo.Search_GetSuitability(#SearchPreferences,
Score.FieldA, Score.FieldB, Score.FieldC) AS OverallSuitabilityScore
from dbo.LocationScores
)
SELECT TOP(10)
Locations.LocationId,
Score.OverallSuitabilityScore,
RANK() OVER (ORDER BY OverallSuitabilityScore) AS OverallSuitabilityRank
FROM dbo.LocationsView Locations
INNER JOIN Score ON Locations.LocationId = Score.LocationId
WHERE Locations.CityId = #LocationId
An old school way of doing this is just to SUBQUERY the expression.
The CTE here only moves the subquery to the top
SELECT TOP(10) LocationId,
OverallSuitabilityScore,
RANK() OVER (ORDER BY OverallSuitabilityScore) AS OverallSuitabilityRank
FROM
(
SELECT
Locations.LocationId,
dbo.Search_GetSuitability(#SearchPreferences,
Score.FieldA, Score.FieldB, Score.FieldC) AS OverallSuitabilityScore
FROM dbo.LocationsView Locations
INNER JOIN dbo.LocationScores Score ON Locations.LocationId = Score.LocationId
WHERE Locations.CityId = #LocationId
) X
