Transact SQL :: Retrieve Latest Record Of Serial Number With Multiple Entries
Sep 30, 2015
I work for an organization that repairs serialized devices. Each time a device is repaired it's serial number is recorded in a database table along with the date it was repaired along with other information about the device. There are multiple cases where a unit has been repaired more than once.
I am trying to write a query that will return the serial only once and that record will be the record of the latest repair date. To sum it up,
Return a list of serials where if a serial exists more than once in the table, return only the instance of the serial record(s) with the max(created_dt). The end result will be a list of distinct serial numbers.
Here is my Query. The problem I believe is in my sub-query but I am not sure how to structure it.
SELECT
S.Id
, RMA
, PinSerial
, L4Serial
, L4Model
[Code] ....

select SERIALNO, Max(TIME)
from dbo.TASK A
join dbo.Status B
on A.TID=B.TID
where A.ID in ('1111',2222')
and A.TYPE='Pen'
group by B.SERIAL_NO, B.TIME
order by BM.TIME
For this query I may get serial no duplicates but times are unique
For that serial no, I have to find the recent time. But if I use group by, I am getting the wrong no

Hi All,
I'm using Microsoft SQL Server Management Studio with SQL Server 2005 (SP2).
I have not had much experience with t-SQL and iterative logic implementation through SQL, therefore I think my problem is fairly basic for most of the pros here.
Here it goes...
I have two tables at hand, TestTab1 and TestTab2.
TestTab1 contains two attributes (columns) namely account_name (nvarchar(50)) and entry_count (int). For all rows in TestTab1, account_name is unique, i.e. for each account_name there is only 1 row in TestTab1. This is my source table.
TestTab2 contains one attribute namely account_name (nvarchar(50)). This table is empty and is my destination table.
I need to insert X entries (rows) for each account_name into TestTab2 where X is the int value in entry_count againt each account_name in TestTab1.
In other words, I need to insert account_name into TestTab2 as many times as the number in entry_count indicates.
I tried reading through the documentation but the help was not friendly enough for me to understand how to implement this.
Looking forward to the pro support.
Thanks,

I€™m working on a database project that will ultimately contain millions of records for each lot. In addition, each lot will have up to 96 corresponding serial number records.
I would like to add a SQL parameter that would tell the database engine to only return X number of records.
For Example:
If table TBL_LOTS contains one million records I would like to limit the return set to 100 for example.
What would I need to add to the SQL command to below to restrict the data set to the first 100 records in the set of one million?
SELECT [LOT NUMBER]
FROM TBL_LOTS
WHERE [STATMENTS]

I need to find the missing months in a table for the earliest and latest start dates per ID_No.  As an example:
create table #InputTable (ID_No int ,OccurMonth datetime)
insert into #InputTable (ID_No,OccurMonth)Â
select 10, '2007-11-01' Union all
select 10, '2007-12-01' Union all
select 10, '2008-01-01' Union all
select 20, '2009-01-01' Union all
select 20, '2009-02-01' Union all
select 20, '2009-04-01' Union all
select 30, '2010-05-01' Union all
select 30, '2010-08-01' Union all
select 30, '2010-09-01' Union all
select 40, '2008-03-01'
For the above table, the answer should be:
ID_No OccurMonth
----- ----------
20 2009-02-01
30 2010-06-01
30 2010-07-01
1) don't include an ID column,
2) don't use the start date/end dates in the data or
3) use cursors, which are forbidden in my environment.

I have this table of Marks as shown below. All I need is to find the average Marks at various intervals of S.no. That is I need averages at every 3rd S.No. as shown.
S.No. Marks
1 ------ 5
2 ------ 5
3 ------ 6 1st Average Value here (16/3)
4 ------ 5
5 ------ 6
6 ------ 7 2nd Average Value here (18/3)
7 ------ 7
8 ------ 7
9 ------ 8 3rd Average Value here (22/3)
10 ----- 8
11 ----- 9
12 ----- 8 4th Average Value here (26/3)
So basically I need a new table which will have 4 average values for the table above. Of-course the table can be much bigger and the average values can be at any nth value of S.No.

I have the following query
WITH summary AS
(SELECT tu.SequenceNumber,
tu.trialid,
tu.SBOINumber,
tu.DisplayFlag,
[Code] ....
I am having trouble with the RowNumber Over Partition By portion of the query. I would like the query to return only the first occurrence of each sboinumber in the table for each trial id. It is only giving me the first occurrence of each sboinumber. I tried including the trialid in the partition by clause, but that is not working.
Sample Data
SequenceNumber  TrialID     SBOINumber

SELECTÂ

We are using a table that may give 1 to and unknown number of data elements (ie. years) . Â How can we break this to show only three years in each row. Â Since we don't know the number years we really won't know the number of rows needed. Â Years are stored in their own table by line. Â
Â
car make year1 year2 year3
A Â volare 1995 1996 1997
a  volare 1997  1998  1999
b toyat  1965   1966  1968
We can pivot out the first X# but we don't know how many lines so we don't know how many rows we will be creating.

I tried:
SELECT *

But this only returns 1 record for 1 Ref field. I need 1 record for each Ref field

I have created the following SQL snippet that is a very simple mock-up illustrating the problem (I hope!) that I am facing:
-- create table
if object_id('tempdb..#tmpdelnotes') is not null
drop table #tmpdelnotes
create table #tmpdelnotes(
DelNote int identity (1,1) ,
DelDate date not null,
Item int not null,
Customer int not null)
[code]...
What I need to retrieve is a unique list of item numbers with information about the latest (DelDate) delivery note. The "Clumsy workaround" works, but is not very pretty when doing multiple table joins. Is it really necessary to use a derived table for this kind of query? Window functions can only exist in the SELECT and ORDER BY clauses, which is understandable since the calculations take place (I would guess) after the aggregations in the HAVING clause.

Someone ran an update statement multiple times so their are multiple entries in the table. Â What is the quickest way to track down the multiple entries? Â I would only want to see where timein and timeoff exist in the table multiple times for the same id. Â So this would be a duplicate
EntryID -- ID Â -- timein -- timeoff

Hi,
I need help desperately. The following is an example of the data that I have.
I have two tables one name Customers and the other named Orders. The tables have the following attributes
CUSTOMER
CustomerNum, CustomerName, OrderNum
ORDER
OrderNum, OrderDesc, CustomerNum
Bare in mind that the CustomerNum can have multiple customers attached to it, example a whole family (I know bad database design but it's too late to change) Let's use the following info for the tables respectively
CUSTOMER
0001 Sharon Bigbsy 1234
0001 Dale Bigbsy 1235
0001 Omar Bigbsy 1236
ORDERS
1234 Chips 0001
1235 Gatorade 0001
1236 Candy 0001
The query i'm using is select Customer.CustomerNum, Customer.CustomerName, Orders.OrderDesc from CUSTOMER, ORDERS where CUSTOMER.CustomerNum = ORDER.CustomerNum
The results are as follows
0001 Sharon Bigbsy Chips 1234
0001 Sharon Bigbsy Gatorade 1235
0001 Sharon Bigbsy Candy 1236
0001 Dale Bigbsy Chips 1234
0001 Dale Bigbsy Gatorade 1235
0001 Dale Bigbsy Candy 1236
0001 Omar Bigbsy Chips 1234
0001 Omar Bigbsy Gatorade 1235
0001 Omar Bigbsy Candy 1236
It's giving all the orders place to each customer name but I need only the following
0001 Sharon Bigbsy Chips 1234
0001 Dale Bigbsy Gatorade 1235
0001 Omar Bigbsy Candy 1236
I'm using SQL in MS Access 2003. Please disregard the abnormalities of the tables, it's someone else's work I inherited with over 6000 entried.
Any help will be greatly appreciated
