Selecting The Earliest Date
Jun 12, 2008
I'm having a mental block on a select statement.
I have a table with the following columns:
KitId int
LotNo varchar(10)
DateReceived smalldatetimeIt is possible to have many rows with the same LotNo but a differing DateReceived I need to write a select statement that returns the KitId for a given LotNo with the earliest DateReceivedso if I had rows:KitId =1, LotNo = 123, DateReceived = 11th May 2008
KitId =2, LotNo = 123, DateReceived = 28th May 2008
KitId =3, LotNo = 125, DateReceived = 28th May 2008
KitId =4, LotNo = 127, DateReceived = 28th May 2008
KitId =5, LotNo = 123, DateReceived = 12th June 2008I would want to retrieve KitId=1 if I provided LotNo 123 as a parameter Whilst it should always be the case that the LotNo with the earliest date will have the lowest KitId I cannot guarantee that will be the case so going for the lowest KitId isn't an optionCan one of you SQL gurus provide me with the statement I need?ThanksNeil

I'm no SQL whizz yet but I'm learning hard, and need to get some information from our DB rather urgently so have resorted to this fantastic forum, only I can't find what I'm looking for.
Basically I'm selecting a whole load of entries that have a (admission)date field after 2001, but I only want to return the Earliest (admission) for each (patients number).
Here is the script I have created to select all the data, but how can I limit the results to just the earliest (admission date) for each (patient).
SELECT
Admission_Year, Admission_Month, Age_On_Admission, [Length of stay(continuing)], [Patient's Number], [Cons epis seq no], Sex, [Main Primary Pas Diag], [Date of Death], [Epi duration], [OP Code1], [Admission date], [Date of Death] - [Admission date] AS [days before death],[Intended Management]
FROM dbo.Admissions
WHERE (Admission_Year > 2001) AND (Age_On_Admission > '64') AND ([Intended Management] = 'inpatient') AND ([Date of Death] IS NULL)
I would really appreciate it if anyone can help with this, I'm sorry I can't really contribute to this forum as an SQL expert as .net is really my forte and I usually spend my time contributing to the asp.net forums. :)

Hi I am having trouble and I don't know why.
I have this query which I pasted below. I need to find the earlist effective date (pcsp_eff), but I need to show all of the fields below in my report like a flat file. I know ususaly when you use Max/Min you have to have a group by, would I group by everything that is in my select statement?
SELECT Distinct
dbo.pcs.pcs_id1,
dbo.pcs.pcs_lname AS [Last Name],
dbo.pcs.pcs_fname AS [First Name],
dbo.pcsp.pcsp_eff AS [Effective Date for Provider],
Min(pcsp_eff) as "earliestEffectivedate",
dbo.pcst.pcst_trm1 AS [Tracking Thru Date],
dbo.pcst.pcst_dat3 AS [Re-cred Letter Sent Date],
dbo.pcst.pcst_dat7 AS [Re-cred Complete Date],
PRO_STATE as "State",
PRO_COUNTY as "County"--, PCSP_NET
FROM dbo.pcs INNER JOIN
dbo.pcst ON dbo.pcs.pcs_id1 = dbo.pcst.pcst_id1 INNER JOIN
pcsp ON pcs.pcs_id1 = pcsp.pcsp_id1 left Join
dbo.pro ON pcs.pcs_id1 = pro.pro_id1
WHERE
(CONVERT(CHAR(10), dbo.pcst.pcst_dat3, 110) <>'03-23-1977') and
(CONVERT(CHAR(10), dbo.pcst.pcst_dat7, 110) = '03-23-1977') and
(pcsp.pcsp_prd = 'DGH') AND
--(pcsp.pcsp_id2 = '0001') and
PCS_CTL = 'I' and
pcsp_NET <> 'DACFP' and
pcs_id1 = '00004307'
Group by pcs_id1

Hi,I have a table (SQL Server 2000) with several date columns in it, all ofwhich are individually NULLable, but in any one row, not all the dates canbe NULL.I want a query which ORDERs BY the earliest date it finds in each row. I'mguessing I have to do this in two steps:STEP 1Using a UDF, find the earliest date and stick it in a new calculatedcolumn "earliest date"STEP 2ORDER BY this UDF-created columnIf this is the right way to go about this, is there a simple SQL way ofdetermining which is the lowest of several dates? (ie of doing STEP 1).Or am I looking at this the wrong way, and missing an easy *one-step* way ofgetting what I want?TIA,JON

I have two dates. How do I get the one that is the lowest. One may be null. I don't want null unless they are both null
I tried..
DECLARE @Handle date

print @Handle
ALTER FUNCTION [dbo].[getTrkLeastDate] (@d1 date, @d2 date)

CREATE TABLE #Dateissue
(ID int,
Code nvarchar (20),
Datein datetime,
Declined datetime )
[Code] .....
I have a table here.  I want  find a way of getting the latest date, when the code is the same.  If the Declined date is null.  Then I still want the latest date.  E.g. ID 3. Â
If the declined date is filled in. Â Then I want to get the row, when the Datein column value is greater then the declined date only.
I tried grouping it by max date, but  i got an error message when trying this out.  Against the code Â
WHERE MAX(Datein) > Declined
An aggregate may not appear in the WHERE clause unless it is in a subquery contained in a HAVING clause or a select list, and the column being aggregated is an outer reference. Â What do I need to do to get both my outputs working?Â

Hi,
I have soma ado.net code that inserts 7 parameters in a database ( a date, 6 integers).
I also use a self incrementing ID but the date is set as primary key because for each series of 6 numbers of a certain date there may only be 1 entry. Moreover only 1 entry of 6 integers is possible for 2 days of the week, (tue and fr).
I manage to insert a row of data in the database, where the date is set as smalldatetime and displays as follows: 1/05/2007 0:00:00 in the table.
I want to retrieve the series of numbers for a certain date that has been entered (without taking in account the hours and seconds).
A where clause seems to be needed but I don’t know the syntax or don’t find the right function
I use the following code to insert the row :
command.Parameters.Add(new SqlParameter("@Date", SqlDbType.DateTime, 40, "LDate"));
command.Parameters[6].Value = DateTime.Today.ToString();
command.ExecuteNonQuery();
and the following code to get the row back (to put in arraylist):
“SELECT C1, C2, C3, C4, C5, C6 FROM Series WHERE (LDate = Today())�
WHERE LDate = '" + DateTime.Today.ToString() + "'"
Which is the correct syntax? Is there a better way to insert and select based on the date?
I don’t get any error messages and the code executes fine but I only get an empty datatable in my dataset (the table isn’t looped for rows I noticed while debugging).
Today’s date is in the database but isn’t found by my tsql code I think.
Any help would be greatly appreciated!
Grtz

Hello,I have a couple of tables. The client tables and the contactedtables.I am not sure how to start on this, what I need is a way to query allmy clientsthen show any client that the last visit and or called day is greaterthan 30 days.Now it gets confusing, Suppose the client was visited more than 30 daysagobut was called only 10 days ago, I really would like to have thisappear on the samequery.So the report would look similar to this below.Visit Date Called DateClientA 2006-11-02 2006-12-16ClientB 2006-12-17 2006-10-30ClientC 2006-10-15 2006-10-16ClientDFields (Simplified)Clients: Name, Address, Phone.Contacted: Name, Date, Visit, Call.I need to query all l names, but I only need the last visit and lastphone call. Then determine if either date is greater than 30 days ifso, display the last date of each type of contact. And if there isnothing for the client in the contacted table this needs to show also,ClientD.Any tips, ideas would be greatly appreciated....ThanksIce

Hi,
I've been wrestling with this problem for a while, but my newbie SQL skills are no match for it, so I'm hoping somebody here can point me in the right direction.
I have the following table, called AccountPayments:
PaymentID CaseID_FK AmountPaid InvoiceDate PaymentDate
12135 250 01/16/2006 01/31/2006
13136 150 01/16/2006 01/31/2006
14 135 200 01/24/2006 02/05/2006
15 136 300 01/24/2006 02/05/2006
16139 120 01/25/2006 02/07/2006
17 136 100 01/25/2006 02/10/2006
18 137 115 01/25/2006 02/13/2006
19 136 110 02/12/2006 02/25/2006
20139 310 02/12/2006 03/06/2006
21 138 220 02/15/2006 03/09/2006
I would like to select all the entries where the payment date is, at the latest, the 7th day of the month following the one in which the invoice was issued.
In other words: If the invoice date is in January, I would like to select all the entries where the payment date is February 7th at the latest. If the invoice date is in February, I would like to select all the entries where the payment date is March 7th at the latest.
So, for the above table, I would like to get the following result:
PaymentID CaseID_FK AmountPaid InvoiceDate PaymentDate
12135 250 01/16/2006 01/31/2006
13136 150 01/16/2006 01/31/2006
14 135 200 01/24/2006 02/05/2006
15 136 300 01/24/2006 02/05/2006
16139 120 01/25/2006 02/07/2006
19 136 110 02/12/2006 02/25/2006
20139 310 02/12/2006 03/06/2006
Does anybody know if it's possible to do this? I'm working with SQL Server 2000 and have been playing around with dateadd, but I can't seem to figure it out.
Thank you for your help.

Good Morning,I have a view that contains rate information, contractIDs, and effectivedates.I need to select the rate info based on contractID and date.I can provide a date and contractID, and I need to select the rate info forthat contract where the effective date is <= dateprovided.I need the 1 record that is closest to that date.I am thinking something with max() perhaps. Any ideas? The <= effectivedate will return several rows, I just need the one closest to the date Iprovide.Thanks for any advice,CK

Here's my current SQL:
SELECT
RN_TEST_ID AS 'Test ID',
MAX(RN_EXECUTION_DATE) AS 'Last Execution Date',
MAX(RN_EXECUTION_TIME) AS 'Execution Time',
RN_DURATION AS 'Run Duration'
FROM RUN
[code]....
Here's a sample of data returned:
Test IDLast Execution DateExecution TimeRun Duration
86722/9/2015 0:0012:08:16180
86822/9/2015 0:0011:29:06181
86842/9/2015 0:0008:29:17119
105252/3/2015 0:0019:03:4089
105252/3/2015 0:0019:10:13305
106682/3/2015 0:0018:55:43103
106682/6/2015 0:0018:10:50123
114572/3/2015 0:0011:40:0726
What I need are two things:
1. The query should only return one record for each test id
2. The record returned should be the most recent. By most recent I mean the RN_EXECUTION_DATE and RN_EXECUTION_TIME of the returned row should be the most recent in time.
For example, in the sample data there are multiple rows with the same test id (for example 10668 and 10525. The 10525 is even more problematic since its execution date is the same for both rows returned - the execution times differ. Again, I want one record per test id and that record should be the most recent in time.

OK. I have this query, works on another box fine.
SELECT *
FROM bookkeep RIGHT OUTER JOIN
acraccts ON LEFT(bookkeep.accnum, 9) = acraccts.p_accnum
WHERE (bookkeep.busdate = '03/09/10') AND (bookkeep.tradetype = 'S')
on my sql box, if i run it, i get no data.
i figured out that if i change the where clause to (bookkeep.busdate='2003/09/10') it works
OR
if i simply put SET DATEFORMAT YMD on the first line before the SELECT * that it also works.
my problem is the basic query is hard coded and i really can't change it.
is there a global sql server setting that will make my sql 2000 sp3 box recognize '30/09/10' as 2003/09/10?

Hi,
I did some tsql a year or so ago, it wasnt much but it allows me to do most things i need to do in my job.
I have created a new database for bookings, each booking has all the relevant details and also the date that it will occur. im trying to create a script that will look for the 10 soonest dates that there is no booking for. at first i thought it would be easy, but now once i have got round to creating it i cant seem to think of a way to make it work!
TABLE: BOOKINGS
FIELD: DATE_BOOKED
has anybody advice on how i can do this?
many thanks,

In SQL 2005 I have the following view:
SELECT TOP (100) PERCENT StockCode, Warehouse, QtyOnHand, QtyAllocated, QtyOnOrder, QtyOnBackOrder, DateLastSale, DateLastStockMove,
DateLastPurchase
FROM dbo.MBL_VW_AgedStock_Sales
ORDER BY StockCode
This basically shows a list of stock codes (there are multiple stock codes the same) and the last sold date. What i need to do is group the stock codes which are the same together, and show the latest date.
For example I could have the following:
STOCK CODE Last Date Sold
PC1113 11/01/2007
PC1104 15/03/2007
PC1113 15/02/2007
What I want to see is a list that shows PC1113 with its latest sold date, i.e.
STOCK CODE Last Date Sold
PC1113 15/02/2007
PC1104 15/03/2007
Any ideas?
Thanks

Hi,
I was wondering how you perform a select statement based on a specific date that will show all the records no matter which times belong to the specific date.
I have been having trouble with this one when using a single date, I think this is because of the time property as no records are displayed.
Thanks for any help.

The AUDIT_ORDERS has these columns: AUDIT_ID, ORDER_ID, AUDIT_DATE and other ones.
The AUDIT_ORDER_LINES has these columns: AUDIT_ID, ORDER_ID, ORDER_LINE_ID, AUDIT_DATE and other ones.
I need to join these two tables in order to select for each order line row the first order having the related audit date lower than or equal to the audit date of the related order line.
I don't want to use the TOP 1 clause or a subquery. I think to complete a such statement:
SELECT OL.Order_Line_ID, O.Order_ID, OL.Audit_Date, O.Audit_Date
FROM AUDIT_ORDER_LINES as OL INNER JOIN AUDIT_ORDERS as O
on OL.Order_ID = O.Order_ID and O.Audit_Date <= OL.Audit_Date ...
I'd like to get the first row of the Audit_Orders with audit_date <= of the audit_date of the Audit_Order_Lines table by using the join clause.
