I've three tables in this mode:
Time1 with column "Data" in format gg/mm/aaaa
Manual with columns "valMan" and "dataora" same format.
Automatic with columns "valAuto" and "dataora" same format.
I must find values "valAuto" from table Automatic where Data.Time1 is = dataora.Automatic and if the value is null I take this value from valMan.Manual in the same Data.Time1 = dataora.Manual
In access sql or vb for access.
Is very important for me... Thank you a lot!!!
For MS Access you can try Iif and IsNull
SELECT Time1.Data,
IIf(IsNull([valAuto]),[valMan],[valAuto]) AS Expr1
FROM (Time1 LEFT JOIN Automatic ON Time1.Data = Automatic.dataora) LEFT JOIN
Manual ON Time1.Data = Manual.dataora;
or
Nz
SELECT Time1.Data,
Nz([valAuto],[valMan]) AS Expr1
FROM (Time1 LEFT JOIN Automatic ON Time1.Data = Automatic.dataora) LEFT JOIN
Manual ON Time1.Data = Manual.dataora;
Don't know about access, but this should do it in MS SQL Server
SELECT
ISNULL(a.valAuto, m.valMan) AS whatIWant
FROM
Automatic a
INNER JOIN Time1 t ON a.dataora = t.Data
INNER JOIN Manual m ON t.Data = m.dataora
The ISNULL command replaces valAuto with valMan if valAuto is null.

I have the following SQL string which tries to combine an INNER JOIN with a LEFT JOIN in the FROM section.
As you can see I use table VIP_APP_VIP_SCENARIO_DETAIL_LE to perform the query. When I use it against this table, Access give me an "Invalid Operation" error.
Interestingly, when I use the EXACT same query using the VIP_APP_VIP_SCENARIO_DETAIL_BUDGET or VIP_APP_VIP_SCENARIO_DETAIL_ACTUALS table, it performs flawlessly.
So why would it work on two tables but not the other? All fields are in all tables and the data types are correct.
As a side note: on the query with the error, if I change the LEFT JOIN to an INNER JOIN, it runs with no problem! I really need a LEFT JOIN though.

tried to mock this up in SQL server with some tables of my own, but the structure seemed to work, this follows the pattern referenced above. (hopefully no syntax errors left here)
SELECT * FROM (

Had help from a friend and we discovered that it was a casting problem between a linked Oracle table and the Access table. To fix the problem we casted both sides of the linked fields to a string:
CSTR(D.[MATERIAL_NUMBER]) = CSTR(V.[ITEM_CODE])

When I am executing the above table in hive I am getting the below error
"Both left and right aliases encountered in JOIN 'SASP'"
On further investigation I founded that we cannot use date between filter in the join on condition. In every post everyone is asking to insert that filter in where condition.
But in our case if we are moving that date between filter to where condition then we are not getting any data since left outer join is not satisfying.
I am getting this issue while executing in HIVE, it is working fine in Teradata and oracle
Please help.
Only equality(=) works in join condition in Hive.Move <= to where clause.
I have the similar issue earlier.Please check below thread.
Hive Select MAX() in Join Condition
Hope this helps.
There might be some common column between CSS407 and SERV_ACCT_ISVC_LINK which might be creating this error.
I'm writing a query with a report file, an employee file and a report distribution file. I would like a list of employee names, each with every report name and a 0 if they don't get the report and a 1 if they do get the report.
select distinct ut.user_name
, ut.emailaddress
, r.name
, iif(ISNULL(rd.employeeid,0)=0, 0,1) AS currentreport
from US_usertable ut
cross join DL_reports r
left outer join DL_Reptdistrib rd
on ut.employeeID = rd.employeeid
For each user, I get a complete set of reports - so the cross join works - but either they get a 1 for all the reports or a 0 for all their reports. I don't understand why this query isn't working. Kindly help if you can. Thanks in advance!!!
I think you are missing a join condition on the report:
select ut.user_name, ut.emailaddress, r.name,
(case when rd.employeeid is null then 0 else 1 end) as currentreport
from US_usertable ut cross join
DL_reports r left outer join
DL_Reptdistrib rd
on ut.employeeID = rd.employeeid and r.?? = rd.??;
The ?? is for the field used to identify the report. I might guess that it is reportID.
Note: I switched the syntax to standard SQL. IIF() is in SQL Server for compatibility with MS Access (why Microsoft didn't put the ANSI standard case in MS Access is beyond me). I also replaced ISNULL() with the ANSI standard IS NULL.
I'm trying to come up with an automated solution for something I do manually now and I only have minimal, bare-bones SQL skill. I usually modify simple queries others have built or will build basic select queries. I have done some reading but don't know how to make it do what I need in this case. I need to come up with something others can use while I am out for a month (and which will save me time when I return).
What I need is to return the fields below where tblThree.EndDate is later than tblFive.ServiceEnd. I have to do a couple of other compares on the dates, but if I get a working query of the first one I can make it work with the others. We use MS SQL Server 2008.
I tried creating sub-queries with aliases and failed miserably at making it work.
These are the table and fields I am working with:
tblOne.ServiceID
tblOne.ServiceYear
tblOne.Status
tblTwo.AccountNbr
tblTwo.AcctName
tblThree.BeginDate (smalldatetime, null)
tblThree.EndDate (smalldatetime, null)
tblFour.ClientID
tblFour.ServiceName
tblFive.ContractID
tblFive.ServiceBegin (smalldatetime, null)
tblFive.ServiceEnd (smalldatetime, null)
This is how the tables are related:
tblOne.ServiceID = tblThree.ServiceID
tblOne.ContractID = tblFive.ContractID
tblOne.ClientID = tblFour.ClientID
tblTwo.AccountNbr = tblFour.Account
I used MS Access 2003 to generate the Join SQL:
SELECT tblOne.ServiceID, tblTwo.AccountNbr,
tblTwo.AcctName, tblFour.ServiceName, tblOne.Status,
tblThree.BeginDate, tblThree.EndDate,
tblOne.ServiceYear, tblFive.ServiceBegin,
tblFive.ServiceEnd
FROM ((tblTwo INNER JOIN tblFour
ON tblTwo.AccountNbr=tblFour.AccountNbr) INNER JOIN (tblThree INNER JOIN tblOne
ON tblThree.ServiceID=tblOne.ServiceID)
ON tblFour.ClientID=tblOne.ClientID) INNER JOIN tblFive
ON tblOne.ContractID=tblFive.ContractID;
Thanks for any help.
Just add a WHERE clause to get started:
SELECT tblOne.ServiceID, tblTwo.AccountNbr,
tblTwo.AcctName, tblFour.ServiceName, tblOne.Status,
tblThree.BeginDate, tblThree.EndDate,
tblOne.ServiceYear, tblFive.ServiceBegin,
tblFive.ServiceEnd
FROM ((tblTwo INNER JOIN tblFour
ON tblTwo.AccountNbr=tblFour.AccountNbr) INNER JOIN (tblThree INNER JOIN tblOne
ON tblThree.ServiceID=tblOne.ServiceID)
ON tblFour.ClientID=tblOne.ClientID) INNER JOIN tblFive
ON tblOne.ContractID=tblFive.ContractID
WHERE tblThree.EndDate > tblFive.ServiceEnd;
SELECT
tblOne.ServiceID,
tblOne.ServiceYear,
tblOne.Status,
tblTwo.AccountNbr,
tblTwo.AcctName,
tblThree.BeginDate,
tblThree.EndDate,
tblFour.ClientID,
tblFour.ServiceName,
tblFive.ContractID,
tblFive.ServiceBegin,
tblFive.ServiceEnd
FROM tblOne
INNER JOIN tblThree
ON tblOne.ServiceID = tblThree.ServiceID
INNER JOIN tblFive
ON tblOne.ContractID = tblFive.ContractID
INNER JOIN tblFour
ON tblOne.ClientID = tblFour.ClientID
INNER JOIN tblTwo
ON tblTwo.AccountNbr = tblFour.Account
WHERE tblThree.EndDate > tblFive.ServiceEnd
The following SQL query returns no data for the LEFT JOIN in MS Access.
SELECT * FROM
(
SELECT Operation_Part.PPC,
Operation_Part.TargetOperationsPerHour as JPH,
Operation_Part.Misc1 as [JPh Alt 1],
STR(Operation_Part.SeqNr) as Sequence,
Operation_Part.idPart,
Operation_Part.idOperationPart,
Operation.OperationType as Operation,
tblOperationType.OperationType as [Operation Type]
FROM tblOperationType
RIGHT JOIN (Operation INNER JOIN Operation_Part ON Operation.idOperation = Operation_Part.idOperation)
ON tblOperationType.idOpType = Operation.OperationTID
WHERE Operation_Part.VsbLDq = 0
AND Operation_Part.idPart <> 0 AND Operation_Part.idPart = 1271)
AS [AA]
LEFT JOIN (SELECT Sum([Cptotal]) AS DownTime,
TransactionDetail.idPart,
STR(TransactionDetail.seq_number) as Sequence
FROM ([Transaction] INNER JOIN TransactionDetail ON [Transaction].idTransaction = TransactionDetail.idTransaction)
WHERE [Transaction].idTransactionType=29
AND TransactionDetail.WorkOrderNumber = 'PR23144'
GROUP BY TransactionDetail.idPart, STR(TransactionDetail.seq_number))
AS [EE]
ON AA.idPart = EE.idPart AND EE.Sequence=AA.Sequence
In SQL Server the query does return the downtime value of 1.08 as required (see pics below).
First select returns:
Second select returns:
MS Access result:
SQL server result:
How do I make it work in MS Access?
This is only a guess, but it may well have something to do with the nulls in the applicable columns of the rows you dont really want.
Suggest you change
SELECT Sum([Cptotal]) AS DownTime,
to
SELECT Sum(IIf(IsNull([CpTotal]), 0, [CpTotal])) AS DownTime
In Access I always use CStr(...) instead of Str(...)
Aside from this, painful though it may be, I'd suggest turning the left-joined component into a separate query, or if you dont use queries, building a temporary table with this data which is then left joined into the original query.
