Query Getting Most Recent Record

Jun 16, 2015

Here's the scenario. Consider the following sample data.

CREATE TABLE #MyTest
(
CustomerNumber INT,
Division CHAR,
SalesRepType INT,
SalesRepNumber INT,
EnterDate DATE

[code]....

Essentially, what I’m attempting to do is for each Customer, Division, SalesRepType determine who the most recent assigned SalesRepNumber is and when (EnterDate) that person was assigned. So using the sample data, I would expect the following results.

CustomerNumberDivisionSalesRepTypeSalesRepNumberAssignedDate
10000A11002/1/2015
10000A23001/28/2015
10000B14002/1/2015
10000B26002/2/2015

I’ve tried various ways of using a CTE and ROW_NUMBER trying to get at this, but the area that is giving me the problem is in Division A, SalesRepType 1. Here is what gets me close, but I’m picking on SalesRepNumber 200 instead of 100 for Division A and

SalesRepType 1.
WITH
cteCust (RowNum, CustomerNumber, Division, SalesRepType, SalesRepNumber, BeginDate)
AS
(
SELECT

[code]....

Joining Record With The Most Recent Record On Second Table

Apr 23, 2008

Could anybody help me with the following scenario:

Table 1 Table2

ID,Date1 ID, Date2

I would like to link the two tables and receive all records from table2 joined on ID and the record from table1 that has the most recent date.

Example:

Table1 data Table2 Data

ID Date1 ID Date2
31 1/1/2008 31 1/5/2008
34 1/4/3008 31 4/1/2008
31 3/2/2008


The first record in table2 would only link to the first record in table1
The second record in table2 would only link to the third record in table1

Any help would be greatly appreciated.
Thanks

Getting Most Recent Record

Sep 4, 2007

I am trying to think of the easiest solution to do this.

What it is, is that I am trying to be alerted, if an account has not had its daily reports ran for x days (for example, 3 days).

I have two tables.

One is a table, with a list of AccountIDs that are to have the report done.

Another is a Log Table, which a record is inserted whenever a report has run. So, if a report has not run, it will not have a record in that table.

Here is the table setup with sample data. I am only going into basics, as the tables are used for a couple other things which are not needed for this.


Code:


Table: Reports_AccountID
ReportID | AccountID
--------------------------
5 | 1234
5 | 987
4 | 1234
3 | 1234
5 | 5677

Log: Reports_Log
LogID | ReportID | AccountID | ReportRunDate
----------------------------------------
9876 | 5 | 1234 | 9/4/2007 10:35:43 AM
9875 | 5 | 987 | 9/4/2007 10:35:43 AM
9874 | 4 | 1234 | 9/4/2007 9:05:43 AM
9873 | 3 | 1234 | 9/4/2007 9:30:17 AM
9872 | 5 | 1234 | 9/3/2007 10:35:43 AM
9871 | 5 | 987 | 9/3/2007 10:35:43 AM
9870 | 4 | 1234 | 9/3/2007 9:05:43 AM
9869 | 3 | 1234 | 9/3/2007 9:30:17 AM
9868 | 5 | 1234 | 9/2/2007 10:35:43 AM
9867 | 5 | 987 | 9/2/2007 10:35:43 AM
9866 | 5 | 5677 | 9/2/2007 10:35:43 AM
9865 | 4 | 1234 | 9/2/2007 9:05:43 AM
9864 | 3 | 1234 | 9/2/2007 9:30:17 AM



so if i wanted to know what report for reportID 5 hasn't run in the past 2 days, it would be accountID of 5677 (last ran on 9/2/2007 10:35:43 AM)

I am not sure where to even start. I am thinking I can grab the latest report ran for all Accounts in the Reports_AccountID table (create temp table and insert most recent log record into that table), and do a date difference between the date and current datetime and select based on datedifference > 2 ?

or would the best way is to do an inner join between the 2 tables for all reports ran in the past 2 days, and then whatever account is not listed in that query, is a report that has not run (do a subquery?)

just trying to think of the best way to do this. any tips/advice would be appreciated

Select Most Recent Record

Dec 21, 2006

Every hour we capture some values from our factory (position of pumps, valves, ...) in our sql server 2000 db.

Normally 1 record is added to the db.
00:00:00
01:00:00
02:00:00
...
21:00:00
22:00:00
23:00:00

All of these values are displayed in an Excel sheet. One sheet contains all the data from one month.

I noticed a problem last week when 2 records were added: first one at 19:00:00 and the second one at 19:00:01

We only want to keep the most recent record (19:00:01) in a situation like this but I can't seem to work out an SQL-statement :o

This is what we have know. It used to work fine untill we had 2 record being added instead of one.
SELECT TimeOfCapture, Value1, Value2, Value3
FROM FactoryTable
WHERE (MONTH(TimeOfCapture) = MONTH(GETDATE())) AND (YEAR(TimeOfCapture) = YEAR(GETDATE()))

Select Most Recent Record??

Apr 27, 2004

Hi,

I want to construct a query that would give the most recent record. Table data looks like -

F1F2F3 F4
20016395074/7/2004 15:40:55
23516395074/6/2004 9:31:54

All columns are strings as the data is obtained from text file. Column F3 can have same or different dates. In the above data select 1st record as it is the most recent.
If data is like -
F1F2F3 F4
20016395074/7/2004 15:40:55
23516395074/7/2004 19:31:54

Select the 2nd record.

Find Most Recent Record For Each Item?

Oct 29, 2014

We have a work order notes table in our ERP system, and I want to see the most recent note record for each work order. Sometimes there will one be one, so I want to see all those, but sometimes there will be several notes for each work order and in this case I want to see only the most recently added note for that work order.

The query below shows some results as an example. In this case I want to see all the records except for work order number DN-000023 where I only want to see the note dated/timed 07-12-2011 16:52 (the most recent one).

select id, worknumber, date, notes from worksordernotes

How To Get Data From 2 Tables ...most Recent Record

Apr 25, 2008

Hello, i have this problem
tbl1 :{ pcb varchar(30) ,serial varchar(30)},result varchar(30)
tbl2: { pcb varchar(30) ,date_time varchar(30),result varchar(30),data1 varchar(30),data2 varchar(30),}

what i need is for a range of serials get the pcb (from tbl1) and for those pcb's get as resultSet the table

tbl3:{pcb,serial,data1,data2} containing most recent data on date_time column.

example. tbl1 ={ pcb1,sn1,pass}
pcb2,sn2,pass


pcb3,sn3,pass}

tbl2={pcb1,date1,pass,dataX1,dataY1
pcb1,date2,pass,dataX2,dataY2
pcb2,date3,pass,dataX3,dataY3
pcb3,date4,pass,dataX4,dataY4
pcb1,date5,pass,dataX5,dataY5
pcb2,date6,pass,dataX6,dataY6}

where date1 is the most recent date

Request:what i want is for serial>=s1 and serial<=s2 get

pcb1,sn1,date1,dataX1,dataY1
pcb2,sn2,date3,dataX3,dataY3



What i already did is this:




Code Snippet
select max(CONVERT(DATETIME,tbl2.date_time,103)),tbl1.serial,tbl2.pcb
from tbl2
left JOIN tbl1
ON tbl2.Pcb=tbl1.pcb
where tbl1.serial>='1' and tbl1.serial<='53'
and tbl2."Result" like 'pass' and tbl1."result" like 'pass'
group by tbl2.pcb,tbl1.serial



And this works correctly.But unfortunately i also need data1 and data2 columns from tbl2.
If i include them in the Select Clause i have to include them also in the group by ,and this gives me also duplicate records.I mean it would return from tbl2, all records containing pcb1,pcb2.


How can i resolve this issue?
Thank you very much,

ElectricC

The Most Recent Record From A Datetime Type Column

Apr 5, 2007

I got some issues regarding selecting the most recent record from a datetime type column.
The probelm consists in following:
Table: News
Needed columns: Letter [varchar]
DateTimePublication [datetime]

Table News: Letter DateTimePublication
FR1_dd_mm_yy dd.mm.yy hh:mm:ss
FR1_dd_mm_yy dd.mm.yy hh+1h:mm:ss
FR1_dd_mm_yy dd.mm.yy hh-2h:mm:ss
EN1_dd_mm_yy dd.mm.yy hh+3h:mm:ss
EN1_dd_mm_yy dd.mm.yy hh+4h:mm:ss
EN1_dd_mm_yy dd.mm.yy hh-5h:mm:ss
DU1_dd_mm_yy dd.mm.yy hh:mm:ss
DU1_dd_mm_yy dd.mm.yy hh+1h:mm:ss
DU1_dd_mm_yy dd.mm.yy hh-2h:mm:ss
FR2_dd_mm_yy dd.mm.yy hh:mm:ss
FR2_dd_mm_yy dd.mm.yy hh+1h:mm:ss
FR3_dd_mm_yy dd.mm.yy hh-2h:mm:ss
EN2_dd_mm_yy dd.mm.yy hh+3h:mm:ss

DU3_dd_mm_yy dd.mm.yy hh+1h:mm:ss
DU4_dd_mm_yy dd.mm.yy hh-2h:mm:ss

The ideea is that there are letters with the same name [Letter] but different DateTimePublication ... and I need only the letters with the most recent DateTimePublication for every letter type like FR_dd_mm_yy/EN_dd_mm_yy/DU_dd_mm_yy.

Thank you for your time and consideration!

Select Most Recent Customer Record From Table Only?

Nov 6, 2007

If I have a table structure similar to the following, how might I query it to obtain the Transaction ID, Transaction Date, and Customer Name for the most recent transaction per customer only:


TransactionTable:
TransactionID TransactionDate TransactionType CustomerName
1 10/1/07 1 Bob
2 8/30/07 2 Janet
3 9/17/07 1 Mike
4 9/25/07 1 Bob


The following query will return all records in the table other than Janets...not what I want:
SELECT Transaction ID, TransactionDate, CustomerName
FROM TransactionTable
WHERE TransactionType = 1
ORDER BY TransactionDate DESC


The following query will return all records in the table other than Janets again, because DISTINCT will use the combo of TransactionID, TransactionDate, and Customer name for uniqueness...not what I want:
SELECT DISTINCT Transaction ID, TransactionDate, CustomerName
FROM TransactionTable
WHERE TransactionType = 1
ORDER BY TransactionDate DESC

The results set I'm looking for would be the following, where only the most recent entry per customer with TransactionType 1 is returned (i.e. one record for Bob):


TransactionTable:
TransactionID TransactionDate CustomerName
1 10/1/07 Bob
3 9/17/07 Mike


I believe I need an appropriate subquery to yield the results I desire, but can't sort out what it is? I do not want to execute multiple queries but subqueries are fine. Unfortunately there's probably an easy answer that my brain is not currently generating. Any help would be appreciated.


Note, this is not a real table, but a sample to illustrate the concept for the query I need.

Thanks.

Find Most Recent Record In Table According To Date Field

Sep 19, 2015

The "Last" function in the query below (line 4 & 5) is not exactly what I'm after. The last function finds the last record in that table, but i need to find the most recent record in the table according to a date field.

Code:
SELECT
tblinmate.statusid,
tblinmate.activedate,
Last(tblclassificationhistory.classificationid) AS LastOfclassificationID,
Last(tblsquadhistory.squadid) AS LastOfsquadID,
tblperson.firstname,
tblperson.middlename,
tblperson.lastname,

[Code] ....

The query below finds the most recent record in a table according to a date field, my problem is i dont know how to integrate this Query into the above to replace the "Last" function

Code:
SELECT a.inmateID,
a.classificationID,
b.max_date
FROM (
SELECT tblClassificationHistory.inmateID,
tblClassificationHistory.classificationID,

SQL 2012 :: Select Record With Most Recent Order Date?

Jun 16, 2014

I am working on a query that needs to return the record order number with the most recent requested delivery date.

It seems to work most of the time, but I have found some glitches for some of the items.

example is my item 10702, it is showing 2 records (both valid ones)
Record 1 is order # 10450-0, requested delivery date 03/21/2014
Record 2 is order # 10510-0, requested delivery date 04/29/2014

I need to only get the records with the most recent delivery date, in this example that would be 04/29/2014

This query is what I have so far:

SELECT
s.PriorQuoteNumber
,s.PriorItemNumber
,s.PriorQuoteDate
FROM
(
SELECT
s.SalesQuoteNumberAS 'PriorQuoteNumber'

[code]....

WHERE s.rn = 1What am I missing in my query> how can I change it so it only returns the most recent date?

SQL Server 2012 :: Find Most Recent Record Of Consecutive Dates

Feb 23, 2015

I have a table full of service invoice records. Some of the invoices are continuous, meaning that there may be an invoice from 01-16-2015 through the end of that month, but then another invoice that starts on feb 1 and goes for 6 months.

I want to only pull the most recent. Keep in mind that there may be other invoices in the same table for a different period. An example might be:

FromDate ToDate Customer Number Contract Number
02/01/2015 07/31/2015 2555 456
01/15/2015 01/31/2015 2555 456
04/01/2013 09/30/2015 2555 123
03/13/2013 03/31/2013 2555 123

From this table, I would like a query that would give me this result:

01/15/2015 07/31/2015 2555 456
03/13/2013 09/30/2015 2555 123

There will likely be more than just 2 consecutive records per contract number.

Most Recent Data Query

I'm trying to retrieve the most recent data using the query below. The issue is there are multiple records which prevent distinct from working. If I could somehow get the most recent data (based on the eventdate field), that would work.

How would I go about this? I've tried order by and group by as well as max but that didn't seem to work.
Any ideas would be greatly appreciated!

Query To Extract The Most Recent Information - Help Please

Mar 23, 2007

Hi all,

I have a table, three records of which look like this:

ID PersonID FirstName LastName PostCode
1 999 Barry White BW13 8GS
2 999 <null> <null> BW13 9GS
3 999 <null> Whites <null>


Both these records refer to the same "person". The records with ID of 2 and 3 represent updates to the record with an ID of 1. The problem is, only the updated data (along with the personID) is represented in records 2 and 3. I need to write query that will return a single record that looks like this:

PersonID FirstName LastName PostCode
999 Barry Whites BW13 9GS

in other words, the most recent information we have for that person.

Does anyone have any ideas? I'd be very grateful as this is proving to be a real pain in the butt!

Kind regards,

Query - Most Recent Entry Per User

Jul 16, 2013

There is a large data table called emp_history on an SQL Server, which contains the employment history of each employee. The significant columns are as follows:

entry_id employee_id start_date position

where entry_id is the primary key and auto-increments.What I need, is to create a query to extract the employee_id and position, based on the most recent record (most recent start_date) for each employee.

Most Recent Date With Most Recent Table ID

Jul 15, 2014

I need to get all customer records with the most recent tDate. A customer should never have duplicate tDate records, as only one record per day is allowed per customer, yet there somehow there are duplicates. Given this, I need to get the record with the Max date and Max ID. the ID column is an auto-incrementing Identity column.Below is the code without the Max ID column logic

SELECT tCustID, MAX(tDate) AS tDate--get MAX tDate records
FROM table1
GROUP BY tCustID

Query Timeouts When Updating A Record Retrieved Through A Websphere JDBC Datasource - Possible Record Locking Problem

Apr 7, 2008

Hi,

We're running a Sage CRM install with a SQL Server 2000 database at the back end. We're using the Sage web services API for updating data and a JDBC connection to retrieve data as it's so much quicker.

If I retrieve a record using the JDBC connection and then try and update the same record through the web services, the query times out as if the record is locked for updates. Has anyone experienced anything similar or know what I'm doing wrong? If I just use DriverManager.getConnection() to establish the connection instead of the datasource, and then continue with the same code I don't get these record locking problems. Please find more details below.

Thanks,
Sarah

The JDBC provider for the datasource is a WebSphere embedded ConnectJDBC for SQL Server DataSource, using an implementation type of 'connection pool datasource'. We are using a container managed J2C authentication alias for logging on.

This is running on a Websphere Application Server v6.1.

Code snippet - getting the record thru JDBC:


DataSource wsDataSource = serviceLocator.getDataSource("jdbc/dsSQLServer");
Connection wsCon = wsDataSource.getConnection();


// wsCon.setAutoCommit(false); //have tried with and without this flag - same results

Statements stmt = wsCon.createStatement();


String sql = "SELECT * FROM Person where personID = 12345";
ResultSet rs = stmt.executeQuery(sql);


if(rs.next()){
System.out.println(rs.getString("lastName"));
}

if (rs != null){
rs.close();
}
if (stmt != null) {

stmt.close();
}
if (wsCon != null) {

wsCon.close();
}

Can't Make New Record (query)

Dec 14, 2007

Hello,

I'm a bit new to MS-SQL so i thought maybe you could help me.

This is my prob. I have an Access application that i have upsized to a MS-SQL server. I have a query based on 3 tables: Customers, Companys and Payreminders. When i run this query, i can't add new records or make any changes.
If i only run the query with the tables: companys and payreminders i can add new records and edit them. If i run a query that's based on companys and customers, i can edit and add new records, but when i run the query based on companys and customers i can't add or edit records.

companys, payreminders: Editable
payreminders, companys: Editable
Companys, customers: Non editable
Companys, payreminders, customers: Non editable


Something must go wrong when i use the companys and customers table. Can anybody help or give a suggestion what to do.

Thanks.
