I am having a confusion on what is happening. So I just need some ideas or clarifications.
I have 3 PHP variables and two PostgreSQL queries:
$date_start = $d1 = "2013-01-01";
$date_end = $d2 = "2013-01-05";
$car = "x";
$query_1 = pg_query($con, "SELECT AVG(longitude) as lon, AVG(latitude) as lat, MAX(longitude) as maxlon, MIN(longitude) as minlon, MAX(latitude) as maxlat, MIN(latitude) as minlat FROM table WHERE car='".$car."' AND testdate>='".$date_start."' AND testdate<='".$date_end."'";
$query_2 = pg_query($con, "SELECT MIN(testtime) as t1, MAX(testtime) as t2 FROM table WHERE car='$car' AND testdate>='$d1' AND testdate=<'$d2' GROUP BY testdate");
The trouble here is that $query_1 gets through fine and gives me a proper result resource, while the other one is always false with an error message:
ERROR: operator does not exist: date =< unknown
LINE 1: ... car='BM1' AND testdate>='2013-04-04' AND testdate=<'2013-04...
^
HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts.
So... any ideas what is happening there? I am sure the queries are almost the same, but for the reason I do not understand PostgreSQL is complaining about one but not the other!
I do not need help on how to fix this, I just need to know the reason. Why the behaviour is different..
Cheers!!
Yours
Andy
I am not a postgress expert but AFAIK there is no =< operator but <=
$query_2 = pg_query($con, "SELECT MIN(testtime) as t1, MAX(testtime) as t2 FROM table WHERE car='$car' AND testdate>='$d1' AND testdate=<'$d2' GROUP BY testdate");

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 the following select statement in ABAP:
SELECT munic~mandt VREFER BIS AB ZZELECDATE ZZCERTDATE CONSYEAR ZDIMO ZZONE_M ZZONE_T USAGE_M USAGE_T M2MC M2MT M2RET EXEMPTMCMT EXEMPRET CHARGEMCMT
INTO corresponding fields of table GT_INSTMUNIC_F
FROM ZCI00_INSTMUNIC AS MUNIC
INNER JOIN EVER AS EV on
MUNIC~POD = EV~VREFER(9).
"where EV~BSTATUS = '14' or EV~BSTATUS = '32'.
My problem with the above statement is that does not recognize the substring/offset operation on the 'ON' clause. If i remove the '(9) then
it recognizes the field, otherwise it gives error:
Field ev~refer is unknown. It is neither in one of the specified tables
nor defined by a "DATA" statement. I have also tried doing something similar in the 'Where' clause, receiving a similar error:
LOOP AT gt_instmunic.
clear wa_gt_instmunic_f.
wa_gt_instmunic_f-mandt = gt_instmunic-mandt.
wa_gt_instmunic_f-bis = gt_instmunic-bis.
wa_gt_instmunic_f-ab = gt_instmunic-ab.
wa_gt_instmunic_f-zzelecdate = gt_instmunic-zzelecdate.
wa_gt_instmunic_f-ZZCERTDATE = gt_instmunic-ZZCERTDATE.
wa_gt_instmunic_f-CONSYEAR = gt_instmunic-CONSYEAR.
wa_gt_instmunic_f-ZDIMO = gt_instmunic-ZDIMO.
wa_gt_instmunic_f-ZZONE_M = gt_instmunic-ZZONE_M.
wa_gt_instmunic_f-ZZONE_T = gt_instmunic-ZZONE_T.
wa_gt_instmunic_f-USAGE_M = gt_instmunic-USAGE_M.
wa_gt_instmunic_f-USAGE_T = gt_instmunic-USAGE_T.
temp_pod = gt_instmunic-pod.
SELECT vrefer
FROM ever
INTO wa_gt_instmunic_f-vrefer
WHERE ( vrefer(9) LIKE temp_pod ). " PROBLEM WITH SUBSTRING
"AND ( BSTATUS = '14' OR BSTATUS = '32' ).
ENDSELECT.
WRITE: / sy-dbcnt.
WRITE: / 'wa is: ', wa_gt_instmunic_f.
WRITE: / 'wa-ever is: ', wa_gt_instmunic_f-vrefer.
APPEND wa_gt_instmunic_f TO gt_instmunic_f.
WRITE: / wa_gt_instmunic_f-vrefer.
ENDLOOP.
itab_size = lines( gt_instmunic_f ).
WRITE: / 'Internal table populated with', itab_size, ' lines'.
The basic task i want to implement is to modify a specific field on one table,
pulling values from another. They have a common field ( pod = vrefer(9) ). Thanks in advance for your time.
If you are on a late enough NetWeaver version, it works on 7.51, you can use the OpenSQL function LEFT or SUBSTRING. Your query would look something like:
SELECT munic~mandt VREFER BIS AB ZZELECDATE ZZCERTDATE CONSYEAR ZDIMO ZZONE_M ZZONE_T USAGE_M USAGE_T M2MC M2MT M2RET EXEMPTMCMT EXEMPRET CHARGEMCMT
FROM ZCI00_INSTMUNIC AS MUNIC
INNER JOIN ever AS ev
ON MUNIC~POD EQ LEFT( EV~VREFER, 9 )
INTO corresponding fields of table GT_INSTMUNIC_F.
Note that the INTO clause needs to move to the end of the command as well.
field(9) is a subset operation that is processed by the ABAP environment and can not be translated into a database-level SQL statement (at least not at the moment, but I'd be surprised if it ever will be). Your best bet is either to select the datasets separately and merge them manually (if both are approximately equally large) or pre-select one and use a FAE/IN clause.
They have a common field ( pod = vrefer(9) )
This is a wrong assumption, because they both are not fields, but a field an other thing.
If you really need to do that task through SQL, I'll suggest you to check native SQL sentences like SUBSTRING and check if you can manage to use them within an EXEC_SQL or (better) the CL_SQL* classes.
Good day.
I am executing a query and encountering:
ORA-01861 literal does not match format string error.
I executed this query and IT WORKED.
SELECT * FROM GCACC_OPERATION_DETAIL WHERE id_notice in (75078741)
AND id_analytical_center in (100000002)
AND interface_date = '2013-06-30'
AND generic_client = 'someGenClient'
AND document_class = 'DOCCLA0001'
AND accounting_tag_identifier = 1
AND generated_actual_acc_doc
IN (select id_accounting_document
from gcacc_accounting_document
where document_status = 'DOCSTA0001');
My other query is written below which DID NOT WORK.
SELECT * FROM GCACC_OPERATION_DETAIL WHERE id_notice IN (75078741)
AND id_analytical_center in (100000002)
AND generic_client = 'someGenClient'
AND document_class = 'DOCCLA0001'
AND accounting_tag_identifier = 1
AND interface_date = '2013-06-30'
AND ind_pending_process = 1
AND operation_type
IN (select cod_develop from gcacc_operation_type where ind_operation = 'B');
This is really weird because the error happens in the date part but I am writing the same syntax for the date part. I maybe missing something silly here and fresher eyes are needed. Thanks in advance!
I don't know what the specific problem is, but assuming "interface_date" is a DATE type, it is bad practice to use literals in a query for a date. This makes the assumption that the default NLS_DATE_FORMAT agrees with your date literal. That will come back to bite you. To ensure that your date constraint is portable, change to this:
AND interface_date = to_date('2013-06-30','YYYY-MM-DD')
I'm a newbie at Hibernate so excuse me if some of this is glaringly obvious but it's been a very, very long day. I am trying to create and execute a simple query in Hibernate and Toad/Oracle.
The Toad/Oracle sql reads:
select
count(*)
from
fpps_owner.fee_claim_payment_lines l,
fpps_owner.fee_claim_payments p
where
l.fee_claim_payment_id = p.fee_claim_payment_id and
p.claim_index = 87167895
The above returns 10 records, which is correct
The following Java code returns 0 records, which is NOT correct
String sLinesAvailable =
"select count(*) from " +
"fpps_owner.fee_claim_payment_lines l, fpps_owner.fee_claim_payments p " +
"where " +
"l.fee_claim_payment_id = p.fee_claim_payment_id and p.claim_index = :id";
Query qLinesAvailable = em.createNativeQuery(sLinesAvailable);
qLinesAvailable.setParameter("id", "87167895"); // fails
qLinesAvailable.setParameter("id", 87167895); // fails
List<Object> out = (List<Object>) qLinesAvailable.getResultList();
BigDecimal x = (BigDecimal) out.get(0);
Returns 0 records. Using .getSingleResult() also returns 0 records.
What am I missing here?
Any help would be GREATLY appreciated!
If you are not seeing any malformed query errors, it seems like the parameter is not binding correctly.
To debug, I'd print out that SQL statement the line after you set the parameter. This is the only way you can see the SQL after the parameter is set in order to compare it with Toad.
What does your binding file look like? Maybe you have a different name in there for the ID, so it's not able to find it based on the name. Trying binding with the parameter's order value, just as a test.
This might give some ideas: http://www.mkyong.com/hibernate/hibernate-parameter-binding-examples/
Best of luck! We've all been there :)
What happens when you try:
(Number) query.getSingleResult();
Your query isn't returning a list, but rather just a count.
Good luck.
I have query
UPDATE THD
SET RepostFlag = 'Y'
,RunListNoRetroPolicyPrepay = ?
,RetroObject = ?
FROM TranHead AS THD
JOIN (
SELECT CustPolicyNo AS CustPolicyNo
,MIN(PremPeriod) AS PremPeriod
FROM TranHead
WHERE RepostFlag = 'Y'
AND PayoutTypeNo = ?
GROUP BY CustPolicyNo
) AS THDToBeReposted ON THD.CustPolicyNo = THDToBeReposted.CustPolicyNo
WHERE THD.RepostFlag = 'N'
AND THD.PremPeriod > THDToBeReposted.PremPeriod
fails in H2 with following message
Table "THD" not found;
I looked at http://www.h2database.com/html/grammar.html#table_expression to see if H2 supports selects in join. It appears it does. Maybe I am missing something when looking at the grammar, but it seems to me that the query should work in H2.
Anyone see what is wrong?
Thanks.
I don't believe FROM is allowed in the UPDATE syntax.
You can't update an alias, you need to have the table name specified.
Complementary to other answers, JOIN (just as FROM) is not allowed in UPDATE for H2. It would be allowed in a sub query.
Essentially, stick to the basic syntax:
UPDATE SomeTable as SomeAlias
SET SomeField = ?
WHERE (%GoWild%)
Whether or not you need the alias is up to your where clause.
