I have a list of 2500 obj numbers stored in Excel for which I need to run the below SQL:
SELECT
a.objno,
a.table_comment,
b.queue_comment
FROM
aq$_queue_tables a
JOIN
AQ$_QUEUES b ON a.objno = b.table_objno
WHERE
a.objno = 19551;
Is there any way I can write a loop on above SQL with objno feeding from a list or from a different table? I also want to store/produce all the results from each loop run as a single output.
I considered the option to upload the numbers into a new table and add a where condition:
a.objno=(SELECT newtab.objectno FROM newtab);
However, the logic I'll be writing in the query would exclude certain objectno results. Let's say that the associated objectno has certain queue_comment as of certain date associated with that objectno. I do not want to pull that record. This condition would match with some objectno and wouldn't match with others. Having that condition and running the query against all the objectno is returning 0 results. I couldn't share the original logic as it would reveal certain business rules and it'll be a violation of some policy.
So, I need to run the query on each objectno separately and combine the results.
I'm totally new to SQL and got this task assigned. I'm aware of the regular loop, for in SQL, but I don't think I can apply them in this situation.
Any guidance or reference links to helpful topics is much appreciated as well.
Thanks in advance for the help.
One option is to upload the object numbers from Excel sheet to a table in the database and run the query as following. Assuming newtab is the table where the objectno are uploaded.
SELECT
a.objno,
a.table_comment,
b.queue_comment
FROM
aq$_queue_tables a JOIN AQ$_QUEUES b on a.objno = b.table_objno
WHERE
a.objno IN (SELECT newtab.objectno FROM newtab);
I have used a subquery here, join to the aq$ can work as well.
Reading the comments and all I think you need to enhance your Excel with 2 additional columns and load to a new table.
IN can be used in the following way too:
SELECT
a.objno,
a.table_comment,
b.queue_comment
FROM
aq$_queue_tables a
JOIN
AQ$_QUEUES b ON a.objno = b.table_objno
WHERE
(a.objno,a.table_comment,b.queue_comment) IN (19551,'something','something');
so with the new table will be:
WHERE
(a.objno,a.table_comment,b.queue_comment) IN
(select n.objno, n.table_comment, n.queue_comment from new_table n)

I'm trying to query my database to pull only duplicate/old data to write to a scratch section in excel (Using a macro passing SQL to the DB).
For now, I'm currently testing in Access alone to only filter out the old data.
First, I'm trying to filter my database by a specifed WorkOrder, RunNumber, and Row.
The code below only filters by Work Order, RunNumber, and Row. ...but SQL doesn't like when I tack on a 2nd AND statement; so this currently isn't working.
SELECT *
FROM DataPoints
WHERE (((DataPoints.[WorkOrder])=[WO2]) AND ((DataPoints.[RunNumber])=6) AND ((DataPoints.[Row]=1)
Once I figure that portion out....
Then if there is only 1 entry with specified WorkOrder, RunNumber, and Row, then I want filter it out. (its not needed in the scratch section, because its data is already written to the main section of my report)
If there are 2 or more entries with said criteria(WO, RN, and Row), then I want to filter out the newest entry based on RunDate and RunTime, and only keep all older entries.
For instance, in the clip below. The only item remaining in my filtered query will be the top entry with the timestamp 11:47:00AM.
.
Are there any recommended commands to complete this problem? Any ideas are helpful. Thank you.
I would suggest something along the lines of the following:
select t.*
from datapoints t
where
t.workorder = [WO2] and
t.runnumber = 6 and
t.row = 1 and
exists
(
select 1
from datapoints u
where
u.workorder = t.workorder and
u.runnumber = t.runnumber and
u.row = t.row and
(u.rundate > t.rundate or (u.rundate = t.rundate and u.runtime > t.runtime))
)
Here, if the correlated subquery within the where clause finds a record with the same workorder, runnumber and row, but with either a later rundate or the same rundate and a later runtime, then the record is returned by the main query.
You need two more )'s at the end of your code snippet. Or you can delete the parentheses completely in this example, MS Access will ad them back in as it deems necessary.
M.S. Access SQL can be tricky as it is not standards compliant and either doesn't allow for super complex queries, or it needs an ugly work around, like having a parentheses nesting nightmare when trying to join more than two tables.
For these reasons, I suggest using multiple Access queries to produce your results.
I read many threads but didn't get the right solution to my problem. It's comparable to this Thread
I have a query, which gathers data and writes it per shell script into a csv file:
SELECT
'"Dose History ID"' = d.dhs_id,
'"TxFieldPoint ID"' = tp.tfp_id,
'"TxFieldPointHistory ID"' = tph.tph_id,
...
FROM txfield t
LEFT JOIN txfielpoint tp ON t.fld_id = tp.fld_id
LEFT JOIN txfieldpoint_hst tph ON fh.fhs_id = tph.fhs_id
...
WHERE d.dhs_id NOT IN ('1000', '10000')
AND ...
ORDER BY d.datetime,...;
This is based on an very big database with lots of tables and machine values. I picked my columns of interest and linked them by their built-in table IDs. Now I have to reduce my result where I get many rows with same values and just the IDs are changed. I just need one(first) row of "tph.tph_id" with the mechanics like
WHERE "Rownumber" is 1
or something like this. So far i couldn't implement a proper subquery or use the ROW_NUMBER() SQL function. Your help would be very appreciated. The Result looks like this and, based on the last ID, I just need one row for every og this numbers (all IDs are not strictly consecutive).
A01";261511;2843119;714255;3634457;
A01";261511;2843113;714256;3634457;
A01";261511;2843113;714257;3634457;

A02";261512;2843114;714259;3634464;
....
I think "GROUP BY" may suit your needs.
You can group rows with the same values for a set of columns into a single row
Here is a picture explaining what I have and what I'm looking for.
Tables and data describing the question.
This originally seemed like a very simple update query but it has proven I really don't understand how the query works. Can someone please explain the SQL I would need to move all the data from tblImport.Addtl_Initiator to the respective blanks under tblEntries.Initiator, and the data from tblImport.Addtl_Date_Initiated to the respective blanks under tblEntries.Date_Initiated? Essentially just moving the data to the left one column, but in a different table.
Additional information: There is a unique ID field on each of the tables not shown in the picture.
Try it with Nz.
UPDATE tblentries
INNER JOIN tblimport
ON tblentries.eid = tblimport.eid
AND tblentries.initiator = tblimport.initiator
AND tblentries.date_initiated = tblimport.date_initiated
SET tblentries.initiator = nz(tblimport.initiator, tblimport.addtl_initiator),
tblentries.date_initiated = nz(tblimport.date_initiated, import.addtl_date_initiated)
This link might also be helpful: coalesce alternative in Access SQL
Use IsNull to get the non-blank values:
SELECT
IsNull(Initiator, Addtl_Inititator) AS Initiator,
IsNull(Date_Initiated, Addtl_Date_Initiated) AS Date_Initiated,
FROM
tblImport
I am new to Access and acually to db's ,
I'm trying to perform a db for recording the results of a really huge survey. So far everything is ok but now that i am designing the Queries I am getting repeated results and I don't know why.
My SQL Statement is:
SELECT T_VALORACIO.IdValoracio, T_ENQUESTA.Treballador,
T_VALORACIO.IdValPreu
FROM (T_ALSECA INNER JOIN T_VALORACIO ON T_ALSECA.idTipus =
T_VALORACIO.idTipus) INNER JOIN T_ENQUESTA ON T_ALSECA.IdAlseca =
T_ENQUESTA.idAlSeca
WHERE (((T_ENQUESTA.Treballador)=True) AND ((T_VALORACIO.IdValPreu)=4));
I would expect getting the results that fit both cases, but the results that fit just the first case are also shown.
Thanks in advance !
Try using instead:
SELECT DISTINCT
This removes duplicate rows.
I have a local access database and in it a query which takes values from a form to populate a drop down menu. The weird (to me) thing is that with most options this query is quick (blink of an eye), but with a few options it's very slow (>10 seconds).
What the query is does is a follows: It populates a dropdown menu to record animals seen at a specific sighting, but only those animals which have not been recorded at that specific sighting yet (to avoid duplicate entries).
SELECT DISTINCT tblAnimals.AnimalID, tblAnimals.Nickname, tblAnimals.Species
FROM tblSightings INNER JOIN (tblAnimals INNER JOIN tblAnimalsatSighting ON tblAnimals.AnimalID = tblAnimalsatSighting.AnimalID) ON tblSightings.SightingID = tblAnimalsatSighting.SightingID
WHERE (((tblAnimals.Species)=[form]![Species]) AND ((tblAnimals.CurrentGroup)=[form]![AnimalGroup2]) AND ((tblAnimals.[Dead?])=False) AND ((Exists (select tblAnimalsatSighting.AnimalID FROM tblAnimalsatSighting WHERE tblAnimals.AnimalID = tblAnimalsatSighting.AnimalID AND tblAnimalsatSighting.SightingID = [form]![SightingID]))=False));
It performs well for all groups of 2 of the 4 possible species, for 1 species it performs well for 4 of the 5 groups, but not for the last group, and for the last species it performs very slowly for both groups. Anybody an idea what can be the cause of this kind of behavior? Is it problems with the query? Or duplicate entries in the tables which can cause this? I don't think it's duplicates in the tables, I've checked that, and there are some, but they appear both for groups where there are problems and where there aren't. Could I re-write the query so it performs faster?
As noted in our comments above, you confirmed that the extra joins were not really need and were in fact going to limit the results to animal that had already had a sighting. Those joins would also likely contribute to a slowdown.
I know that Access probably added most of the parentheses automatically but I've removed them and converted the subquery to a not exists form that's a lot more readable.
SELECT tblAnimals.AnimalID, tblAnimals.Nickname, tblAnimals.Species
FROM tblAnimals
WHERE
tblAnimals.Species = [form]![Species]
AND tblAnimals.CurrentGroup = [form]![AnimalGroup2]
AND tblAnimals.[Dead?] = False
AND NOT EXISTS (
SELECT tblAnimalsatSighting.AnimalID
FROM tblAnimalsatSighting
WHERE
tblAnimals.AnimalID = tblAnimalsatSighting.AnimalID
AND tblAnimalsatSighting.SightingID = [form]![SightingID]
);
