In Pervasive SQL 11 I could use a IF statement in the ORDER BY:
SELECT *
FROM (
SELECT
D1001 as 'part_number',
'' as 'required_date',
'' as 'confirmed_date'
FROM PULAGER
WHERE
D1001 LIKE '1121%'
UNION
SELECT
D5410 as 'part_number',
D5511 as 'required_date',
D5513 as 'confirmed_date'
FROM PUIKOKRO
WHERE
D5410 LIKE '1121%'
) as t1
ORDER BY part_number, IF (confirmed_date = '', required_date, confirmed_date)
But after an upgrade version 15.10.031, I get the error "Reference to column name not allowed in ORDER BY with UNION". No error if I remove the IF statement. Any suggestions?
First order by part_number and then order by required_date or confirmed_date depending on the state of confirmed_date.
I solved it by moving the IF statement to the SELECT to create a new column 'sort_date' and wrapping it all with another SELECT. Doesn't feel like the most beautiful solution, but it works.
SELECT * FROM (
SELECT t1.*, IF (confirmed_date = '', required_date, confirmed_date) as 'sort_date' FROM t1
) ORDER BY part_number, sort_date

Before I go any further please mind that I am not well experienced with SQL.
I have one query that is getting a single value (netto value) such as:
WITH cte_value_net AS (
SELECT
nvl(min(value_net),0) as value_net
FROM (
SELECT
i.serial as serial,
nvl(lag(i.value_net) OVER (PARTITION BY i.serial ORDER BY i.month), i.value_net) as value_net
FROM
inventory i
WHERE
i.ctypde IN (
SELECT
ctypde
FROM
appar ap
WHERE
ap.serial = in_serial -- this is the variable I want to set
)
AND
i.month IN (to_char(add_months(sysdate, -1), 'YYYYMM'), to_char(add_months(sysdate, -2), 'YYYYMM'))
AND
i.serial = in_serial -- this is the variable I want to set
) vn
GROUP BY vn.serial
)
In here I have to feed in the variable in_serial that I thought I could get from another subquery such as:
SELECT
(SELECT * FROM cte_value_net) AS value_net
FROM (
SELECT
lap.serial AS in_serial
FROM
applap lap
)
but I can not wrap my head around it why this in_serial is not visible to my custom CTE. Could someone explain me how can I propagate the value from subquery like this?
The error I am obviously getting is:
SQL Error [904] [42000]: ORA-00904: "IN_SERIAL"
Unfortunately I do not have any sample data. What I want to achieve is that I could feed in the returned in_serial from main subquery to my CTE.
Before I can get value_net I need my main query to return the in_serial, otherwise I do not have access to that value.
The trick I use is to produce an extra CTE that I usually call params that includes a single row with all computed parameters. Then, it's a matter of performing a CROSS JOIN with this CTE in any other CTE, subquery or main query, as needed.
For example:
with
params as ( -- 1. Create a CTE that returns a single row
select serial as in_serial from applap
),
cte_value_net AS (
select ...
from inventory i
cross join params -- 2. cross join against the CTE anywhere you need it
where ...
and i.serial = params.in_serial -- 3. Use the parameter
)
select ...
First, your second query is not syntactically correct, as there's a ',' before the FROM. You can write your query like this:
WITH cte_value_net AS (
SELECT
serial, nvl(min(value_net),0) as value_net
FROM (
SELECT
i.serial as serial,
nvl(lag(i.value_net) OVER (PARTITION BY i.serial ORDER BY i.month), i.value_net) as value_net
FROM
inventory i
WHERE
i.ctypde IN (
SELECT
ctypde
FROM
appar ap
WHERE
ap.serial = i.serial
)
AND
i.month IN (to_char(add_months(sysdate, -1), 'YYYYMM'), to_char(add_months(sysdate, -2), 'YYYYMM'))
) vn
GROUP BY vn.serial
)
select ...
from cte_value_net s join applap lap on (lap.serial=s.serial)
(adjust query to your schema ....)
I am trying to create a table in teradata with sql, but I keep getting the following error:
CREATE TABLE FAILED. [3707] Syntax error, expected something like a name or a Unicode delimited identifier or an 'UDFCALLNAME' keyword or a 'SELECT' keyword or '(' between '(' and the 'WITH' keyword
My goal is to create a table that takes the maximum data, named "verwerkingdatum" in my code for every "contract_nr". Without the create table statement it worked just fine. Now I'm trying to create a table out of this. But I get the error above.
Here is my code:
create table mi_temp.beslagrek_saldo as
(SEL * FROM( WITH x AS
(
SELECT geld_contract_event_id, contract_nr, contract_soort_code,
contract_hergebruik_volgnr,
verwerking_datum,
event_dat,

saldo_na_muteren_eur,
saldo_na_muteren_dc_ind,
valuta_datum,
geld_transactie_soort_code,
tegenrekening_nr,
tegenrekening_naam,
boek_datum,
storno_ind,
mutatie_bedrag_orig,

WHERE verwerking_datum >= 1181201 AND verwerking_datum <= 1181231
)
SELECT geld_contract_event_id, contract_nr, contract_soort_code,

WHERE RowNum = 1))
If I'm reading your post correctly, are you are trying to is filter your select so that your rownum = 1. You can just use qualify to accomplish that.
create table foo as (
SELECT geld_contract_event_id, contract_nr, contract_soort_code,
contract_hergebruik_volgnr,
verwerking_datum,
event_dat,
valuta_code,
saldo_na_muteren_orig,
saldo_na_muteren_eur,
saldo_na_muteren_dc_ind,
valuta_datum,
geld_transactie_soort_code,
tegenrekening_nr,
tegenrekening_naam,
boek_datum,
storno_ind,
mutatie_bedrag_orig,
mutatie_bedrag_eur,
mutatie_bedrag_dc_ind,
soort_overboeking,
tegenrekening_nr_num,
automaat_transactie_type,
automaat_id,
automaat_datum,
automaat_tijd
from
MI_VM_Ldm.vgeld_contract_event
WHERE verwerking_datum >= 1181201 AND verwerking_datum <= 1181231
qualify ROW_NUMBER() OVER (PARTITION BY contract_nr ORDER BY verwerking_datum DESC) =1
) with data;
I am working with a tool that would extract some data from an Access Database. So basically, i am working on a query to get this data.
Below is the code i am currently working on.
I am getting an error: Syntax error in FROM clause
I can't seem to find where the query is going wrong. I would appreciate any help! Thank youu.
EDIT: putting my actual query
SELECT table_freq.*, IIF(table_freq.txn_ctr > (table_ave_freq.ave_freq * 3), "T", "F") as suspicious_flag

I have this query
SELECT DAL_ROWNOTABLE.DAL_ID FROM
(
SELECT ticket.id AS "DAL_ID", ROWNUMBER ( Order By ticket.id ) AS "DAL_ROWNUMBER"
FROM ticket_table ticket
WHERE ( ticket.type = N'I' )
AND
(
ticket.tenant IS NULL OR ticket.tenant IN
(
SELECT * FROM

SELECT tenant_group_member.tenant_id

ORDER BY ticket.id
)
)
)
) DAL_ROWNOTABLE
WHERE DAL_ROWNOTABLE.DAL_ROWNUMBER BETWEEN 1 AND 21
What is the problem with the allow query that is throwing ORA-00936 missing expression? anyone? Any help will be appreciated...Error thrown at column:80 which is at the beginning of first order by:
ORA-00936 usually indicates a syntax error.
ROWNUMBER is not an Oracle function. Unless you have a user-defined function of that name I suspect the function you're looking for is ROW_NUMBER().
Your query can be much simplified. It has things like extra layers of subqueries and an unnecessary order by in an in subquery. What you want to do with rownumber you can do with just rownum:
SELECT DAL_ROWNOTABLE.DAL_ID
FROM (SELECT ticket.id AS "DAL_ID"
FROM ticket_table ticket
WHERE (ticket.type = N'I' ) AND
(ticket.tenant IS NULL OR
ticket.tenant IN (SELECT tgm.tenant_id
FROM tenant_group_member tgm
WHERE tgm.tenant_group = HEXTORAW('30B0716FEB5F4E4BB82A7B7AA3A1A42C')
)
)
ORDER BY ticket.id
) DAL_ROWNOTABLE
WHERE rownum <= 21;
I once wrote similar queries as below in oracle, and it worked at that time. now I try to do put this in prepareStatement of Derby JDBC.
SELECT THREADID,THREADID2,SIMILARITY FROM S WHERE
(THREADID,THREADID2) IN
(
SELECT T1.ID,T2.ID FROM
(
( SELECT T.ID FROM T WHERE T.POSTTYPEID = '1' ORDER BY ANSWERCOUNT DESC FETCH FIRST 200 ROWS ONLY ) AS T1
JOIN
( SELECT T.ID FROM T WHERE T.POSTTYPEID = '1' ORDER BY ANSWERCOUNT DESC FETCH FIRST 200 ROWS ONLY ) AS T2
)
)
It turned out that I got errors as:
java.sql.SQLSyntaxErrorException: Syntax error：Encountered "," at line 1, column 78
I checked the code, and this error points to the (THREADID,THREADID2) part, is it that this is not supported in JDBC Derby?
no
(THREADID,THREADID2) IN
not working
you must seperate like
WHERE THREADID IN ('your condition') OR THREADID2 IN ('your condition')
