I have expression with db_link to MS SQL:
select b."Str" as "State" ,a."_Fld9059" as "Date" from
"_InfoRg9050"#SQLSERVER.UISLAB.COM a INNER JOIN
"EnumTexts"#SQLSERVER.UISLAB.COM b
on a."_Fld9052RRef" = b."_IDRRef"
where a."_Fld10998" = '1104000009' and
a."_Fld10998" = to_date(max(a."_Fld9059"),'dd.mm.yyyy')
order by a."_Fld9059" desc;
I want to upload value with maximum date. Can anybody help me ?
When I run this query I get ORA-00934 error.
The immediate cause of the error you are getting is that MAX() appears in the WHERE clause. One possible workaround, which might be what you intended, would be to use a subquery in the WHERE clause to identify the maximum date:
SELECT b.Str AS State,
a._Fld9059 AS Date
FROM _InfoRg9050 a
INNER JOIN EnumTexts b
ON a._Fld9052RRef = b._IDRRef
WHERE a._Fld10998 = '1104000009' AND
a._Fld10998 = (SELECT MAX(TO_DATE(_Fld9059, 'dd.mm.yyyy')) FROM _InfoRg9050)
ORDER BY a._Fld9059 DESC
However, it is not clear why you are comparing _InfoRg9050._Fld10998 to both the string '1104000009' and a date. You will need to resolve this on your own I believe to get a meaningful result.
Thank you for your help. I got it.
SELECT b."Str" AS "State"
FROM "_InfoRg9050"#SQLSERVER.UISLAB.COM a
INNER JOIN "EnumTexts"#SQLSERVER.UISLAB.COM b
ON a."_Fld9052RRef" = b."_IDRRef"
WHERE a."_Fld10998" = '1104000009' AND
a."_Fld9059" = (select MAX(a."_Fld9059") from "_InfoRg9050"#SQLSERVER.UISLAB.COM a
INNER JOIN "EnumTexts"#SQLSERVER.UISLAB.COM b
on a."_Fld9052RRef" = b."_IDRRef"
where a."_Fld10998" = '1104000009')
ORDER BY a."_Fld9059" DESC

I had an issue with the LEft outer join and my query was little bit wierd. Tried searching for it , but did not get any clues.
This is happening due to were clause has been added.
The query below is not working as expected.
SELECT count(*) from
BN_DATA_TEMP.EDS_DELIVERYITEM_GBQ_SAMPLE_DATA A
LEFT OUTER JOIN BN_DATA_TEMP.TBL_EDS_DELIVERYITEMS_DATES B
on (
to_Date(substr(A.LASTUPDATEDTIME,1,10)) = '2020-05-31'
and to_Date(substr(B.LASTUPDATEDTIME,1,10)) = '2020-05-31'
and A.deliveryid = B.deliveryid )
where B.deliveryid is null;
Trying to get Records in A but not in B. But the count is very different and it is wrong.
I need to consider only the dates with 2020-05-31 from both the tables.
Modified like the below and it gave the correct result.
select count(*) from
(SELECT * from
BN_DATA_TEMP.EDS_DELIVERYITEM_GBQ_SAMPLE_DATA where to_Date(substr(LASTUPDATEDTIME,1,10)) = '2020-05-31' ) A
LEFT OUTER JOIN
(select * from
BN_DATA_TEMP.TBL_EDS_DELIVERYITEMS_DATES where to_Date(substr(LASTUPDATEDTIME,1,10)) = '2020-05-31' ) B
on A.deliveryid = B.deliveryid
where B.deliveryid is null;
I have never use much of Left outer joins for Data validation. So thought of posting over here and learn the same.
Thanks in Advance.
I have only been using Toad/Oracle for a few weeks so am still learning coding etc I have knowledge of SQL Code in Access and trying to now learn Oracle.
I need to return the max date from UCMRBILDAT from tbl BIC/AZUCDMO0100 but only from contracts which are contained in linked tbl LH_DAT
I have also tried a having MAX UCMRBILDAT but this didnt work.
UCMRBILDAT (/BIC/AZUCDMO0100)
UC_MRESULT (/BIC/AZUCDMO0100)
UC_MRSTAT (/BIC/AZUCDMO0100
UC_MRCAT (/BIC/AZUCDMO0100)
CONTRACT_NUMBER (LH_DAT)
UC_MR_NUMB (/BIC/AZUCDMO0100) + (/BIC/AZUCDMO0200)
SELECT UCMRBILDAT,
UC_MRESULT,
UC_MRSTAT,
UC_MRCAT
FROM LH_DAT
( SELECT CONTRACT_NUMBER, MAX (UCMRBILDAT) MXBD
FROM SAPSR3."/BIC/AZUCDMO0100"
GROUP BY CONTRACT_NUMBER) GMR
LEFT OUTER JOIN SAPSR3."/BIC/AZUCDMO0200"
ON (CONTRACT_NUMBER = UCCONTRACT)
INNER JOIN SAPSR3."/BIC/AZUCDMO0100"
ON ("/BIC/AZUCDMO0200".UC_MR_NUMB = "/BIC/AZUCDMO0100".UC_MR_NUMB)
WHERE CONTRACT_NUMBER = '2000014420'
AND UCMRBILDAT = MXBD
AND MR.CONTRACT_NUMBER = GMR.CONTRACT_NUMBER
Max bill date from BIC/AZUCDMO0100 but only for contracts contained in table LH_DAT
EDIT NEED MAX DATE FOR UCMRBILDAT ON BELOW SCRIPT
SELECT CONTRACT_NUMBER,
UCMRBILDAT,
UC_MRESULT,
UC_MRCAT
FROM LH_DAT
LEFT OUTER JOIN SAPSR3."/BIC/AZUCDMO0200"
ON (CONTRACT_NUMBER = UCCONTRACT)
INNER JOIN SAPSR3."/BIC/AZUCDMO0100"
ON ("/BIC/AZUCDMO0200".UC_MR_NUMB = "/BIC/AZUCDMO0100".UC_MR_NUMB)
WHERE CONTRACT_NUMBER = '2000014420'
AND "/BIC/AZUCDMO0200".SOURSYSTEM = 'SP'
AND "/BIC/AZUCDMO0200".UCDELE_IND <> 'X'
To get the max value of "BIC/AZUCDMO0100".UCMRBILDAT where there's a linked value from LH_DAT you'd want to use:
SELECT MAX(ba.UCMRBILDAT)
FROM SAPSR3."BIC/AZUCDMO0100" ba
INNER JOIN LH_DAT ld
ON ld.some_field = ba.some_field
There must be fields which link "BIC/AZUCDMO0100" and LH_DAT together, but in your query they're not specified. Find those fields, plug them in to the query above, and you should get the result you're looking for.
I'm practically new in using oracle and I bumped into a blocker. Below is the query that I created based on what I have researched online to update multiple columns of a table with values from a nested join statement.
UPDATE
(
SELECT
A.COLUMN1 OLD_COLUMN1,
BC.COLUMN1 NEW_COLUMN1,
A.BALANCE OLD_COLUMN2,
BC.COLUMN2_MIN NEW_COLUMN2,
A.COLUMN3 OLD_COLUMN3,
BC.COLUMN3 NEW_COLUMN3
FROM TABLE_A A
INNER JOIN
(
SELECT B.TWWID,
B.ITEMDATE,
B.COLUMN2_MIN,
C.COLUMN3,
C.COUNTRYID,
C.COLUMN1
FROM TABLE_B B
LEFT OUTER JOIN TABLE_C C
ON TO_CHAR(B.ID) = TO_CHAR(C.ID)
) BC
ON A.ID = BC.ID
AND A.DATE = BC.DATE
)ABCUPDATE
SET ABCUPDATE.OLD_COLUMN1 = ABCUPDATE.NEW_COLUMN1,
ABCUPDATE.OLD_COLUMN2 = ABCUPDATE.NEW_COLUMN2,
ABCUPDATE.OLD_COLUMN3 = ABCUPDATE.NEW_COLUMN3;
Selecting the sub-query returns the expected results but when I run the update script as a whole an error is returned.
ORA-01779: cannot modify a column which maps to a non key-preserved
table
Can anyone please explain why I encounter this error and what adjustments can I do to the script to make it work?
Thanks in advance!
I created a view from tables using these queries
CREATE VIEW AVAIL_TOOLS AS
SELECT T.TOOL_NAME AS "Name", R.RETAILER_NAME AS "Retailer", T.RETAILER_NUM AS "Number", I.TI_STATUS AS "Status",
(SELECT
CASE
WHEN DETAIL_RETURNDATE IS NULL THEN TO_CHAR(DETAIL_DUEDATE,'Day, Month, DD, YYYY')
ELSE 'Now' END FROM DETAILRENTAL) AS "Expected Avaliablity"
FROM TOOL T
INNER JOIN RETAILER R
ON T.RETAILER_NUM = R.RETAILER_NUM
INNER JOIN TOOLINSTANCE I
ON T.TOOL_NUM = I.TOOL_NUM
WHERE (I.TI_STATUS = 'Rented') OR (I.TI_STATUS = 'Available')
ORDER BY T.TOOL_NAME;
now when I try to run SELECT * FROM AVAIL_TOOLS
I receive the error ORA-01427: single-row subquery returns more than one row.
The case I am running in the query obviously seems to be the problem. Now is there anyway I could change the queries around. I am trying to create a view where if the return date is null it will be available when it is returned other wise it should be now.
I'm at a loss on how I should change about to get the resulted needed.
Query below should do what you want when you fill proper join condition.
CREATE VIEW AVAIL_TOOLS AS
SELECT T.TOOL_NAME AS "Name", R.RETAILER_NAME AS "Retailer", T.RETAILER_NUM AS "Number", I.TI_STATUS AS "Status",
CASE
WHEN DETAIL_RETURNDATE IS NULL THEN TO_CHAR(DETAIL_DUEDATE,'Day, Month, DD, YYYY')
ELSE 'Now' END "Expected Avaliablity"
FROM TOOL T
INNER JOIN RETAILER R
ON T.RETAILER_NUM = R.RETAILER_NUM
INNER JOIN TOOLINSTANCE I
ON T.TOOL_NUM = I.TOOL_NUM
LEFT OUTER JOIN DETAILRENTAL DR
ON (I.ID? = DR.TOOL_INSTANCE_ID?) --HERE fill join
WHERE (I.TI_STATUS = 'Rented') OR (I.TI_STATUS = 'Available')
ORDER BY T.TOOL_NAME;
Second option is adding to subquery with case where clause based on the same condition as join:
where I.INSTANCE_ID = DETAILRENTAL.INSTANCE_ID
You are combining the result of that CASE expression for ALL rows in DETAILRENTAL with ALL the rows from the three-table join. Instead, you probably only want the "expected availability" for the specific tool in the main SELECT. You could fix it by making the subquery into a correlated subquery; but it makes more sense to just have the CASE expression as a column in the outer SELECT, not wrapped within a subquery, and to add a join to DETAILRENTAL on whatever you need to join on (probably TOOL_NUM?)
select col_1,
col_2
from tbl_a A,
tbl_b B,
( select col_1,col_2 from tbl_c where clo_c_1 <> '1' ) C
where A.col_1 = B.col_1
and A.col_2 = B.col_2
and (A.col_2 = B.col_2
or C.col_2 = A.col_2);
My environment is Oracle,when I run this SQL,if the sub SQL C hasn't got a result,then the entire SQL returns NULL.Whereas if C has a result(not null) which fits other condions,there could be a result.Would somebody explain why sub SQL at the from area need to be not NULL?Thanks very much.
You need to bring yourself into the 90s and start using standard joins:
select col_1,
col_2
from tbl_a A
inner join
tbl_b B
on A.col_1 = B.col_1
and A.col_2 = B.col_2
left join
( select col_1,col_2 from tbl_c where clo_c_1 <> '1' ) C
on
C.col_2 = A.col_2
As a guess. I'm not entirely sure what your join conditions should be but that's my first attempt.
This is expected behaviour. When you join two result sets, you only want to get results where the join criteria is satisfied. If the criteria are not satisfied, you should get no results.
If I run the query "get me all the employees older than 65, and get their departments", if there are no employees older than 65, you would not expect to get any results, even if there are some departments in the database.
SELECT emp.name, dept.dept_name
FROM emp
JOIN dept
ON (emp.dept_no = dept.dept_no)
WHERE emp.age > 65;
As the others said, if you actually want to get rows regardless of whether the subquery has any results, you need to use an outer join.
