SELECT Query Syntax To Display Only The Top Record For Duplicate Records
Oct 6, 2005
Good day!
I just can't figure out how I can display only the top record for the duplicate records in my table.
Example:
Table1
Code Date
01 10/1/05
01 10/2/05
01 10/3/05
02 9/9/05
02 9/9/05
02 9/10/05
My desired result would be:
Table1
Code Date
01 10/1/05
02 9/9/05
Thanks.

I am duplicating a record from my asp.net page in to the database. When i click on save I am getting the following error message
Violation of PRIMARY KEY constraint 'PK_clientinfo'. Cannot insert duplicate key in object 'clientinfo'. The statement has been terminated.
The above message i am getting since i have tried to duplicate the clientname field of my table which is set as the primary key.
What i want is instead of this message in the browser i need to display an alert saying "the clientname entered already exists" by checking the value from the database.
Here is my code. pls modify it to achieve the said problem
if(Page.IsValid==true) { conn.Open(); SqlCommand cmd = new SqlCommand("insert into clientinfo (client_name, address) values ('"+txtclientname.Text+"', '"+txtaddress.Text+"')", conn); cmd.ExecuteNonQuery(); conn.Close(); BindData(); txtclear(); System.Web.HttpContext.Current.Response.Write("<script>alert('New Record Added!');</script>"); Response.Redirect("Clientinfo.aspx"); }

I have a table that "Geography" that has the following columns: city, state, zip
There are tons of duplicate cities in this table. I ran this query and it shows me the number of occurrences of each city. I want to delete all the duplicates except for 1. I don't want to do this manually as there are a lot of records.
What would the SQL look like to delete the duplicate records but keep at least one?

Hi All,
Here is my story, how to change a column called Flag_Status based on the maximum Updated date. i.e. i want to make Flag_Status be 1 for the records which have maximum Updated_date (current record) and the rest to make it 0. for example accountID 1 has three records updated, but only one is current the rest are historical, thus i want the history record to be Falg_status 0 and the current record be 1. Note that Inserted_Date and Updated_Date are created using SSIS Derived column During loading the source table, it helps me when each record is inserted into the Data warehouse.
Here is My source table Name: Source_table,
CREATE TABLE dbo.Source_table
(
AccountID INT PRIMARY KEY,
Price int,
Address varchar(30),
added DATETIME DEFAULT GETDATE(),
edited DATETIME DEFAULT GETDATE(),
Flag_Status Int Default 1
)
GO
Here is the Fact_table
CREATE TABLE dbo.Fact_table
(
Fact_table_Key Int Identity (1, 1) NOT NULL,
AccountID INT,
Price INT,
Address varchar(30),
added DATETIME DEFAULT GETDATE(),
edited DATETIME DEFAULT GETDATE(),
editor VARCHAR(64),
Flag_Status Int Default 1,
Inserted_Date DATETIME DEFAULT GETDATE(),
Updated_Date DATETIME DEFAULT GETDATE()
)
GO
Source_table:
AccountID Price Address added edited Flag_Status
---------------- --------- ------------- ----------- ------------- ------------------
1 10 xyz 01-2006 01-2006 1
2 14 abc 02-2006 02-2006 1
3 13 mno 03-2006 03-2006 1
Here is the fact table, table name= Fact_table
Fact_table_Key AccountID Price Address added edited Flag_Status Inserted_Date Updated_Date
-------------------- ------------- --------- ------------ ------- --------- ---------------- ------------------ -------------------
1 1 10 xyz 01-2006 01-2006 1 05-2006 NULL
2 2 14 abc 02-2006 02-2006 1 05-2006 NULL
3 3 13 mno 03-2006 03-2006 1 05-2006 NULL
4 1 17 ght 01-2006 06-2006 1 NULL 08-2006
5 2 18 dmc 02-2006 07-2006 1 NULL 08-2006
6 3 20 kmc 03-2006 09-2006 1 NULL 10-2006
7 1 19 xyz 01-2006 11-2006 1 NULL 12-2006
8 2 19 klm 02-2006 01-2007 1 NULL 02-2007
9 3 21 pqr 03-2006 03-2007 1 NULL 04-2007
Here is what i am thinking: But it gives me Wrong Flag_Status.
UPDATE Fact_table
SET Flag_Status =
CASE
WHEN (SELECT Max(Updated_Date) From Fact_table
WHERE AccountID IN (SELECT AccountID FROM Fact_table
Group By AccountID Having Count(AccountID)>1)) >
(SELECT Max(edited) From Source_table
WHERE Flag_Status = 1)
THEN 1
WHEN (SELECT AccountID From Source_table
Group By AccountID
Having Count(AccountID) =1) =
(SELECT AccountID From Fact_table
WHERE Updated_Date IS NULL)
THEN 1
ELSE 0
END

I am looking for some help in pulling certain people out of a table
This is the basic setup of my table
PK ID NAME MEETING
1 11111 Joe CLASS98
2 22222 Jane CLASS98
3 33333 Bob CLASS98
4 11111 Joe CLASS04
5 22222 Jane CLASS04
6 44444 Sally CLASS04
What I am wanting to do is Select only the people who attended CLASS98 but didn't attend CLASS04
I could just remove the CLASS04 people by sorting if I could just return the rows that do not duplicate the ID and meeting is either CLASS04 or CLASS98
Either way would get me to my goal.
Any help is GREATLY appreciated.
Thanks

I have a requirement to mark duplicate records when I pull them from the database.
However, I only want to mark the 2nd, 3rd, 4th etc record - not the first one.
The code I have below creates a column called Dupes but marks all the duplicates - including the first one.
Is there a way to only mark the 2nd, 3rd, 4th etc record ?
SELECT *, cs.CallStatusDescription as CSRStatusDesc, cs2.CallStatusDescription as CustomerStatusDesc, (Select MAX(CallAttemptNumber)From CallResults cr Where cl.Id = cr.CallLogId) as CallAttemptNumber,
Dupes = (select count(id) from CallLogswhere (CustomerHomePhone != '' AND cl.CustomerHomePhone = CustomerHomePhone)OR (CustomerBusinessPhone != '' AND cl.CustomerBusinessPhone = CustomerBusinessPhone)AND DealerId= 'hdsh' AND CSRStatus IS NULLand datediff(d, logdate, getdate()) <= 21),
FROM CallLogs cl left Join CallStatus cs on cs.Id = cl.CSRstatusleft Join CallStatus cs2 on cs2.Id = cl.Customerstatus Where SaleStage IN ('1', '2', '3', '4', '5', '6') And (LogProcessFlag = 1 Or LogProcessFlag = 0)And DealerId='hdsh'And Logdate Between '08/01/2007' And '08/31/2007'

I am trying to build a select statement that will
1). find records where a duplicate field exists.
2.) show the ItemNo of records where the Historical data is ' '.
I have the query which shows me the duplicates but I'm stuck when trying to only show records where the Historical field = ' '.
Originally I thought I could accomplish this goal with a sub query based off of the original duplicate result set but SQL server returns an error.
Below you will find a temp table to create and try in your environment.
create table #Items
(
ItemNovarchar (50),
SearchNo varchar (50),
Historical int
[Code] ....
Ultimately I need a result set that returns 'ATMR10 MFZ N', and 'QBGFEP2050 CH DIS'.

My query wants to insert new supplier if there is any. And it should ignore, if the supplier is already present in the table. But it is trying to insert the supplier which is already available. For example, I have PART A with 2 suppliers ABC and DEF. I am getting data from third party for PART A with supplier DEF. As per the condition, it should ignore the record because DEF is already available . But my query is trying to insert supplier DEF and following that, I am getting primary constraint error.
-- Inserting new preferred supplier into R5CATALOGUE

Hello,
I have two tables, Promotion and Promolocation. The Promotion table is used to set up promotions or sales, and consists of a PromoID, StartDate, and EndDate. Each PromoID is referenced in the Promolocation table, which is used to assign items to a promotion for various locations or stores. The Promolocation table consists of PromoID, LocID, SkuID, PromoPrice, and DiscLevel.
There are times where an item or SkuID will exist in more than one promotion, however, our application is currently not intelligent enough to determine which promotion to use, so it sets the active promotion based on the StartDate being before other promotions' StartDate and the EndDate being after other promotions' EndDate.
I want to find all promoid's where a sku exists in more than one promotion. I want to signify which promotion is active, using 1 as the first active promotion, 2 as the next active, 3 as the next, etc. To determine which promotion is the first active promotion, the StartDate must be before any of the other promotions' StartDate, and the EndDate must be after other promotions' EndDate. If the promotions' StartDate is after the other promotions' StartDate but not before the other promotions' EndDate, and the EndDate is before or on other promotions' EndDate, then that's the second active promotion. If the StartDate is the same as other promotions' StartDate, but the EndDate is before other promotions' EndDate, then that's the third active promotion.
For example:
PromoID StartDate EndDate
------- --------- -------
PROMO1 1/1/2004 1/1/2006 (1st Active Promotion)
PROMO2 2/1/2004 1/1/2006 (2nd Active Promotion)
PROMO3 1/1/2004 12/1/2005 (3rd Active Promotion)
Here's a query I am using to display all active promotions:
select
pl.promoid,
pr.startdate,
pr.enddate,
pl.locid,
pl.skuid,
pl.promoprice,
pl.disclevel
from
promolocation pl
inner join
promotion pr
on
pl.promoid = pr.promoid
where
pr.enddate >= getdate()
Thanks for your help.

Hi,
I am facing with the following problem.
I am using bar chart to display my report.
My MDX query is as follows:
SELECT
NON EMPTY { [Measures].[SUM_COUNT] } ON COLUMNS,
TopCount ( Filter ( {[DIM].[NAME].[NAME]}, [Measures].[SUM_COUNT] <> 0 ) , 10, [Measures].[SUM_COUNT] ) ON ROWS
FROM
[USAGE]
where <criteria>
I want to show the topmost 10 records. For some criteria I get the results in the chart.
But for some criteria or say for wrong criteria, there are no records. In such a case the X-axis contains all values for {[DIM].[NAME].[NAME] and value for the Y-axis is all 0. Its kind of blank report it will restrict to 10 records.
In such a scenario I want to show a message to the user saying "No records found", which I have set in the No Rows property of the chart.
If I remove the TopCount clause then I get the above message, which is obvious.
So how do I acheive the same message but at the same time limiting the records to 10?
How can I acheive this in my scenario? Can something be done at the query end?
any help is appreciated.
Thanks in advance!

I have a SQL query I need to design to select name and email addressesfor policies that are due and not renewed in a given time period. Theproblem is, the database keeps the information for every renewal inthe history of the policyholder.The information is in 2 tables, policy and customer, which share thecustid data. The polno changes with every renewal Renewals in 2004would be D, 2005 S, and 2006 L. polexpdates for a given customer couldbe 2007-03-21, 2006-03-21, 2005-03-21, and 2004-09-21, with polno of1234 (original policy), 1234D (renewal in 2004), 1234S (renewal in2005), and 1235L (renewed in 2006).The policy is identified in trantype as either 'rwl' for renewal, or'nbs' for new business.The policies would have poleffdates of 2004-03-21 (original 6 monthpolicy) 2004-09-21 (first 6 month renewal) , 2005-03-21 (2nd renewal,1 year), 2006-03-21(3rd renewal, 1 yr).I want ONLY THE LATEST information, and keep getting earlyinformation.My current query structure is:select c.lastname, c.email, p.polno, p.polexpdatefrom policy p, customer cwhere p.polid = c.polidand p.polexpdate between '2006-03-01 and 2006-03-31and p.polno like '1234%s'and p.trantype like 'rwl'and c.email is not nullunionselect c.lastname, c.email, p.polno, p.polexpdatefrom policy p, customer cwhere p.polid = c.polidand p.polexpdate between '2006-03-01 and 2006-03-31and p.polno like '1234%'and p.trantype like 'nbs'and c.email is not nullHow do I make this query give me ONLY the polno 123%, or 123%Sinformation, and not give me the information on policies that ALSOhave 123%L policies, and/ or renewal dates after 2006-03-31?Adding a 'and not polexpdate > 2006-03-31' does not work.I am working with SQL SERVER 2003. Was using SQL Server 7, but foundit was too restrictive, and I had a valid 2003 licence, so I upgraded,and still could not do it (after updating the syntax - things likeusing single quotes instead of double, etc)I keep getting those policies that were due in the stated range andHAVE been renewed as well as those which have not. I need to get onlythose which have NOT been renewed, and I cannot modify the database inany way.*** Free account sponsored by SecureIX.com ****** Encrypt your Internet usage with a free VPN account from http://www.SecureIX.com ***

I have a new installation of SQL Server 2000 Dev Edition on a Win2K3 Standard Edition Server that I used for development. I just set this machine up in th last week and installed all Win2K3 patches and then installed SQL2K and SP3a. I have a single named instance. I just noticed today that I cannot view table data or use the Query part of EM. When I right click a table and select Open Table->Return All Rows it gives me an error dialog "An unexpected error happened during this operation". While the EM is diplaying this dialog the EM screen looks like Internet Explorer and says "Action Canceled - You might not have permission to view this directory or page using the credentials you supplied." I believe that this is a EM issue as I cannot view table content on other remote server. ANy ideas? Might this be an IE security patch disallowing some connectivity ?--Frank--Message posted via http://www.sqlmonster.com

Hi,
Please help me with an SQL Query that fetches all the records from the three tables but a unique record for each forum and topicid with the maximum lastpostdate. I have to bind the result to a GridView.Please provide separate solutions for SqlServer2000/2005.
I have three tables namely – Forums,Topics and Threads in SQL Server2000 (scripts for table creation and insertion of test data given at the end). Now, I have formulated a query as below :-
SELECT ALL f.forumid,t.topicid,t.name,th.author,th.lastpostdate,(select count(threadid) from threads where topicid=t.topicid) as NoOfThreads
FROM
Forums f FULL JOIN Topics t ON f.forumid=t.forumid
FULL JOIN Threads th ON t.topicid=th.topicid
GROUP BY t.topicid,f.forumid,t.name,th.author,th.lastpostdate
ORDER BY t.topicid ASC,th.lastpostdate DESC

0 I want all the rows from the Forums,Topics and Threads table and the row with the maximum date (the last post date of the thread) as shown above.
The scripts for creating the tables and inserting test data is as follows in an already created database:-
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[FK__Topics__forumid__79A81403]') and OBJECTPROPERTY(id, N'IsForeignKey') = 1)
ALTER TABLE [dbo].[Topics] DROP CONSTRAINT FK__Topics__forumid__79A81403
GO
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[FK__Threads__topicid__7C8480AE]') and OBJECTPROPERTY(id, N'IsForeignKey') = 1)
ALTER TABLE [dbo].[Threads] DROP CONSTRAINT FK__Threads__topicid__7C8480AE

I hope I'm posting this in the correct forum. If not I apologize. I have a nested select query that I imported from Oracle:
Oracle Version:
Code Snippetselect avg(days) as days from (
select dm_number, max(dm_closedate) - max(comment_closed_date) as days from dm_data
where
dm_type = 'prime' and
dm_closedate <= '31-dec-2007' and
dm_closedate >= '1-dec-2007' and
program = 'aads'
group by dm_number)
SQL Version:
select round(abs(avg(days)), 0) as days from
(select dm.dm_number, abs(datediff(DAY,max(dm.dm_closedate), max(dm.comment_closed_date))) as days
from dm_data dm, ProgramXref px
where
px.Program_Name = 'aads'
and dm.Program_Id = px.Program_Id
and dm.dm_type = 'prime'
and dm.dm_closedate <= '31-dec-2007'
and dm.dm_closedate >= '1-dec-2007'
group by dm.dm_number)
In Oracle the query runs fine. In SQL I am getting a "Line 10: Incorrect syntax near ')'." error. If I run just the nested portion of the query, there are no errors. It only happens when the first query tries to query the nested query. Can anyone help me get the syntax correct?
Thanks,
Lee

I would like to have records in my Absences table split up into multiple records in my query based on a start and end date.
A random record in my Absences table shows (as an example):
resource: 1
startdate: 2014-08-20 09:00:00.000
enddate: 2014-08-23 13:00:00.000
hours: 28 (= 8 + 8 + 8 + 4)
I would like to have 4 lines in my query:
resource date hours
1 2014-08-20 8
1 2014-08-21 8
1 2014-08-22 8
1 2014-08-23 4
Generating the 4 lines is not the issue; I call 3 functions to do that together with cross apply.One function to get all dates between the start and end date (dbo.AllDays returning a table with only a datevalue column); one function to have these dates evaluated against a work schedule (dbo.HRCapacityHours) and one function to get the absence records (dbo.HRAbsenceHours) What I can't get fixed is having the correct hours per line.
What I now get is:
resource date hours
...
1 2014-08-19 NULL
1 2014-08-20 28
1 2014-08-21 28
1 2014-08-22 28
1 2014-08-23 28
1 2014-08-24 NULL
...
... instead of the correct hours per date (8, 8, 8, 4).
A very simplified extract of my code is:
DECLARE @startdate DATETIME
DECLARE @enddate DATETIME
SET @startdate = '2014-01-01'
SET @enddate = '2014-08-31'
SELECTh.res_id AS Resource,
t.datevalue,
(SELECT ROUND([dbo].[HRCapacityHours] (h.res_id, t.datevalue, t.datevalue), 2)) AS Capacity,
(SELECT [dbo].[HRAbsenceHours] (9538, h.res_id, t.datevalue, t.datevalue + 1) AS AbsenceHours
FROMResources h (NOLOCK)
CROSS APPLY (SELECT * FROM [dbo].[AllDays] (@startdate, @enddate)) t
p.s.The 9538 value in the HRAbsenceHours function refers to the absences-workflowID.I can't get this solved.

If I wanted to run a query on any table and in the recordset that is returned have an 'id' field (or whatever) with the record id of that record, how would I do this?
I'm thinking something like
Select field1, field2, recordNumber // derived somehow - not an actual field
from table
where the result woule be:
field1 field2 1
field1 field2 2
field1 field2 3
field1 field2 4
field1 field2 5
...
