Duplicate Entry In A Primary Key Field

Jul 10, 2007

Hi everybody couldn't get through with saving my data on the table with two primary keys...

my table structure is this

pubidintUnchecked (primary key)
pubchar(1)Unchecked
publchar(1)Unchecked
pubcodechar(2)Unchecked (primary key)

a sample data is here

pubid pub publ pubcode

1 a b ab
1 b b bb
2 a b ab
2 b b bb


when i save this table modifying the pubid and pubcode as primary keys the following error displays...

Unable to create index 'PK_PUBS3'.
CREATE UNIQUE INDEX terminated because a duplicate key was found for index ID 1. Most significant primary key is '51'.
Could not create constraint. See previous errors.
The statement has been terminated.


what i understand is that on the primary key duplicates are not allowed how could i allow it?

thanks

How Duplicate Data Can Make An Entry????

Oct 5, 2007

Hi,
I want to know the different sources, mediums and ways using which the duplicate recoprds or adta can make an entry in our database tables. I found 4 ways for this from many articles on net that are as follows:


Duplicate data might arrive at your database via an interface to another system
Data is loaded into table from other sources because during data loads, the integrity constraints are disabled
Merging data from disparate systems
Inheriting a poorly designed databaseBut is there any other ways also present????? Please tell me???

Thanks,

How To Prevent A Second Entry Being Inserted With Primary Key Value? (C#)

Jan 16, 2008

Ok, this is a really stupid question, but I can't seem to find an answer I understand. In my SQL database I have a a table called MasterSkillList, to which the user can write by using a little web form with a text box and a drop down list. The table has 2 fields, Skill and Attribute. Skill is the primary key, as no skill can appear twice. What I want to do is prevent just that, I don't want people to enter the same skill more than once. So how do I tell the user that the entry allready exists in the database?
 My C#  Code is as follows:1 protected void btnSubmit_Click(object sender, EventArgs e)
2 {
3 srcAddSkill.InsertParameters["Skill"].DefaultValue = txtSkillName.Text;
4 srcAddSkill.InsertParameters["Attribute"].DefaultValue = ddlAbility.SelectedValue;
5 try
6 {
7 srcAddSkill.Insert();
8 lblErrorMessage.Text = "The skill '" + txtSkillName.Text + "' has been added. It is based on a character's " + ddlAbility.SelectedItem + " score.";
9 lblErrorMessage.Visible = true;
10 txtSkillName.Text = "";
11 }
12 catch (Exception ex)
13 {
14 lblErrorMessage.Text = "An exception has occurred. " + ex.Message;
15 lblErrorMessage.Visible = true;
16 }

Transact SQL :: Query To Combine Each Duplicate Found Entry

Nov 19, 2015

I am wanting to create a query so that I can combine each of the found duplicates into one entry.

An example of this is:

Name |ID |Tag |Address |carNum
-------------------------------------------------------
Bob Barker |2054| 52377 |235 Some road |9874
Bill Gates |5630| 69471 |014 Washington Rd. |3700
Bob Barker |2054| 97011 |235 Some road |9874
Bob Barker |2054| 40019 |235 Some road |9874
Steve Jobs |8501| 73051 |100 Infinity St. |4901
John Doe |7149| 86740 |7105 Bull Rd. |9282
Bill Gates |5630| 55970 |014 Washington Rd. |3700
Tim Boons |6370| 60701 |852 Mnt. Creek Rd. |7059

In the example above, Bob Barker and Bill gates are both in the database more than once so I would like the output to be the following:

Bob Barker |2054|52377/97011/40019|235 Some road |9874
Bill Gates |5630|69471/55970 |014 Washington Rd.|3700
Steve Jobs |8501|73051 |100 Infinity St. |4901
John Doe |7149|86740 |7105 Bull Rd. |9282
Tim Boons |6370|60701 |852 Mnt. Creek Rd. |7059

Notice how Bob Barker & Bill Gates appends the tag row (the duplicated data) into one row instead of having multiple rows. This is because I do not want to have to check the previous ID and see if it matches the current id and append to the data.

Removing Duplicate Rows With CTE And Partition - Need Most Recent Entry

Sep 28, 2007

I have tested the code below to remove duplicate table entries based on the field IntOOS. This code works; however, I want to ensure I am removing the oldest entries and keeping the most recent entry. The field to key on this would be something like Max(ID). What would be the best way to ensure I keep the most recent table entry?

Duplicate Data Entry When Using The ASP.NET Web Site Administration Tool For Logins

Nov 5, 2007

Hello All,

I am using the Web Site Administration Tool with the ASP.NET login controls to create/manage user logins & roles for my site.

I have exported the ASPNETDB.MDF into my SQL Database ready to use with my app. The problem that I'm having is that whenever I add a user, using either the Web Site Administration Tool or the Classes available in the code-behind. The entry is doubled up in the database.

This is not a problem when logging on....however, when it comes to deleting a user it will only take one of the entries out and leave the duplicate in there. So if the administrator has deleted a user from the app and then tried to create another one with the same UserName (Which whomever is well within his/her rights to be able to do), they cannot because the entry which has "stay behind" in the database conflicts with the entry.

Any help on this matter would be greatly apprieciated. If any more info on this matter is required please ask (It was quite hard to try and explain this :-)

CREATE TABLE DUPLICATE OBJECT/DUPLICATE FIELD NAME ERROR Msg 2714

Oct 2, 2007

Hello Everyone:

I am using the Import/Export wizard to import data from an ODBC data source. This can only be done from a query to specify the data to transfer.

When I try to create the tables, for the query, I am getting the following error:




Msg 2714, Level 16, State 4, Line 12

There is already an object named 'UserID' in the database.

Msg 1750, Level 16, State 0, Line 12

Could not create constraint. See previous errors.


I have duplicated this error with the following script:


USE [testing]

IF OBJECT_ID ('[testing].[dbo].[users1]', 'U') IS NOT NULL

DROP TABLE [testing].[dbo].[users1]

CREATE TABLE [testing].[dbo].[users1] (

[UserID] bigint NOT NULL,

[Name] nvarchar(25) NULL,

CONSTRAINT [UserID] PRIMARY KEY (UserID)

)

IF OBJECT_ID ('[testing].[dbo].[users2]', 'U') IS NOT NULL

DROP TABLE [testing].[dbo].[users2]

CREATE TABLE [testing].[dbo].[users2] (

[UserID] bigint NOT NULL,

[Name] nvarchar(25) NULL,

CONSTRAINT [UserID] PRIMARY KEY (UserID)

)

IF OBJECT_ID ('[testing].[dbo].[users3]', 'U') IS NOT NULL

DROP TABLE [testing].[dbo].[users3]

CREATE TABLE [testing].[dbo].[users3] (

[UserID] bigint NOT NULL,

[Name] nvarchar(25) NULL,

CONSTRAINT [UserID] PRIMARY KEY (UserID)

)



I have searched the "2714 duplicate error msg," but have found references to duplicate table names, rather than multiple field names or column name duplicate errors, within a database.

I think that the schema is only allowing a single UserID primary key.

How do I fix this?

TIA

Automatic Field Entry

Nov 17, 2007

Hi,I'm creating a database using SQL Server 2005 Express Edition (Comes with Visual Web Developer). The table which I am creating has the following Fields - all don't allow nulls:IDUserIdDateDescription(UserId is a foreign key to asp_net_Users as I am supporting user accounts)Basically what I need to do is create a page where I as an Administrator can log onto and enter just the text for the field Description. Then once I upload this I wish all users to visit the site and view this Description on a page however with it also listing the Administrator who wrote it along with the Date. I wish both of these fields to be added automatically (UserId to display the User Name and the Date to display the date and time with which the Description was added - However these need to be editable by the Administrator if he/she wishes to change them).Can anyone point me in the right direction on the steps needed to create this scenario?Thanks for any helpDaniel

Data Entry In A Datetime Field

Jan 22, 2007

Hi,

I am using SQL Server Management Studio Express for creating my database. I also use the GUI tools for data entry instead of using T-SQL. Whenever I try to enter a value in a field that has a smalldatetime data type, it gives me an error message -
"Invalid Value for cell (row 1, column 2).
 
The changed value in this cell was not recognised as valid.
.Net Framework Datatype: Datetime
Error Message: Index was outside the bounds of the array.
Type a value appropriate for this data type or press ESC to cancel the change."

Now I have tried entering all different combinations in which one can enter a date or a time or both, including in the format I have specified in the windows regional settings, but I always get the same error message.

How do I input data into the field?

Hi,

I use only English as the default language for all programs, OS included. The date in question is not just one particular date, it is any date or time value, and I've been facing this issue ever since I started using SQL Server Express a year ago. Only I haven't used it much since, and need to seriously develop something now, that I bothered to ask the question here.

Some examples of the values I tried entering yesterday, and none of them worked. (I got the same error message for each value) -

1-1-2007

01-01-2007

01/01/2007

01,01,2007

01:01:2007

Jan 01, 2007 (this is the format I have specified for short date in the Win regional settings - MMM dd, yyyy)

I even tried entering time alongside with all those above figures in the format -

11:35 PM

11:35 AM

23:35

The only time value(s) I didn't try was/were - hh:mms tt - which is the time format specified in my Win regional settings, neither standalone, nor with the date values.

I also tried entering a time value standalone, without the date. Still no go.

(Also, as I have gleaned from previous posts, if all goes well and SQL Server accepts your data, then if you enter just a date value in a datetime field, then the field automatically gets populated with the value of the system time at that moment, and if you enter just a standalone time value, then the date part will be filled by the system date value on the date of the entry. Am I correct so far?)

Now I'm in a real fix because of the inability to enter date/time values.

Could you please help me out?

I don't understand. I can enter the datetime values in all the above mentioned combinations if I use an Insert or Update statement using T-SQL, but I can't seem to enter data in the datetime/smalldatetime fields at all if I try to use the GUI of Management Studio Express to enter data. (right click the table, select show table, and the grid view pops up). Ditto for using GUI tools of Visual Studio Express. Is this a bug in the Visual Studio (Express) software?

Also, my other concerns are, once I develop a front-end for data entry using VB, will I face the same issues with data entry in the datetime fields using the GUI of the front end? I can't test that right now, because I'm still learning VB, and cannot create the front end just yet.





Post#7

Originally posted by me this afternoon, but it never showed up on the page -

Alright, I have done a complete reinstall of Win XP, and have also reinstalled SQL Server Express. Prior to this, I had SQLExpress SP1, but now I have directly installed SP2.

Now I continue to face the same issue. SQL Server will not accept any value for any datetime field, unless it is entered as an SQL insert statement. It won't accept the value entered in the exact same format as the insert statement from the GUI mode of Management Studio Express, nor will it take any values from any GUI developed using VBExpress and the fill dataset method. It throws an error everytime. I don't know any other way of databinding and updating/inserting using VB at this time.

I am at my wits' end because of this. I ask again, is this a bug in SQL Server Express? If so how do I report it to MS and get my issue resolved? If not, even then how can I solve this problem?





Could someone please help me out? I am stuck and cannot use the product at all, without the datetime field.

PRIMARY Key Cannot Have Duplicate Value

BCP And Duplicate Primary Keys

Sep 10, 1998

Hi All,
I`m using BCP to import ASCII data text into a table that already has many records. BCP failed because of `Duplicate primary key`.
Now, is there any way using BCP to know precisely which record whose primary key caused that `violation of inserting duplicate key`.
I already used the option -O to output error to a `error.log`, but it doesn`t help much, because that error log contains the same error message mentioned above without telling me exactly which record so that I can pull that `duplicate record` out of my import data file.
TIA and you have a great day.

Lookup Allows Duplicate Primary Key

Aug 13, 2004

I have a Transform Data Task that copies a lot of data from my source system. Unfortunately, I cannot use a DISTINCT in the SQL from the source system, due to a very poor ODBC driver!
So, when I am creating my primary key, I am trying to do a lookup on the PK column before I insert the record to see if it exists. If it does, then I skip the row. The lookup references the target database of the task.

The problem I have is that the lookup doesn't find any duplicates loaded from the database. It allows them through and causes the database to throw a primary key error.

Has anyone experienced this, or think they know what I'm doing wrong?

Duplicate Row Excluding Primary Key

Jul 6, 2007

I am trying to duplicate a row in a table and this is the solution I came up with:

CREATE PROC duplicate_row(@my_primary_key)
AS

DECLARE @sql_stmt varchar(MAX)
SET @sql_stmt = 'INSERT INTO My_Table('

SELECT@sql_stmt = @sql_stmt + COLUMN_NAME + ','
FROMINFORMATION_SCHEMA.COLUMNS
WHERETABLE_NAME = 'My_Table'
ANDCOLUMN_NAME NOT IN ('my_primary_key','title')

SET @sql_stmt = @sql_stmt + 'title) SELECT '

SELECT@sql_stmt = @sql_stmt + COLUMN_NAME + ','
FROMINFORMATION_SCHEMA.COLUMNS
WHERETABLE_NAME = 'My_Table'
ANDCOLUMN_NAME NOT IN ('my_primary_key','title')

SET @sql_stmt = @sql_stmt +' title+''_copy'' AS title FROM My_Table WHERE my_primary_key = '+LTRIM(STR(@my_primary_key))

EXEC(@sql_stmt)

However this stored proc is horrifically slow. I was wondering if anyone had any suggestions on a better way to accomplish this.

Finding Primary Key Value(s) Having Duplicate Row Information

Feb 23, 2001

Hi,

I am putting my problem in an example as I Feel it would be clear.

Assume my table PEOPLE is having 4 columns with 6 rows, the SlNo being primary key.
SlNo Name LastName birthdate
1 A B x --
2 C B x |-- 1 pair (A, B, x)
3 D E y --|------------
4 A E y | |
5 A B x __| |-- 2'nd pair (D, E, y)
6 D E y ---------------
In this scenario, I need to find SlNo values having similar values in other columns. The o/p for above must be:
1
5
0
3
6
0 (0 needs to include in output for distinction in the sets)

(a)IS THIS POSSIBLE TO DO IN ONE SELECT STATEMET? and HOW?
(b)If I create another temp table tempPEOPLE and select distinct row information of the 2'nd, 3'rd and 4'th columns from the PEOPLE table and
then selecting SlNo's where the information match, I am able to get o/p
1
5
3
6
without 0...and I cannot makeout the distinct sets in this.
HOW DO I FIND THE DISTINCTION IN SETS?

Delete Duplicate Records Without Primary Key

Now I want the result in following way:

I have tried the following query and its running fine but its not a dynamic stuff.

DELETE top (SELECT COUNT(*)-1 FROM aaa WHERE id ='3') --or put some number

Ignore Duplicate Primary Keys

Mar 27, 2008

I have one table that stores log messages generated by a web service. I have a second table where I want to store just the distinct messages from the first table. This second table has two columns one for the message and the second for the checksum of the message. The checksum column is the primary key for the table.

My query for populating the second table looks like:
INSERT INTO TransactionMessages ( message, messageHash )
SELECT DISTINCT message, CHECKSUM( message )
FROM Log
WHERE logDate BETWEEN '2008-03-26 00:00:00' AND '2008-03-26 23:59:59'
AND NOT EXISTS (
SELECT * FROM TransactionMessages
WHERE messageHash = CHECKSUM( Log.message ) )

I run this query once per day to insert the new messages from the day before. It fails when a day has two messages that have the same checksum. In this case I would like to ignore the second message and let the query proceed. I tried creating an instead of insert trigger that only inserted unique primary keys. The trigger looks like:

IF( NOT EXISTS(
SELECT TM.messageHash
FROM TransactionMessages TM, inserted I
WHERE TM.messageHash = I.messageHash
) )
BEGIN
INSERT INTO TransactionMessages ( messageHash, message )
SELECT messageHash, message FROM inserted
END

That didn't work. I think the issue is that all the rows get committed to the table at the end of the whole query. That means the trigger cannot match the duplicate primary key because the initial row has not been inserted yet.

Does anyone know the best way to do this?

Thanks for your help,
Drew

I have table variable in which I am inserting data from sql server database. I have made one of the columns called repaidID a primary key so that a clustered index will be created on the table variable. When I run the stored procedure used to insert the data. I have this error message; Violation of Primary key Constraint. Cannot insert duplicate primary key in object. The value that is causing this error is (128503).

I have queried the repaidid 128503 in the database to see if it is a duplicate but could not find any duplicate. The repaidID is a unique id normally use by my company and does not have duplicates.

I want to import a data file into a sql table. The table has a primary key but the data could have a duplicate value in the PK column (error in the source data). How can I "trap" for this type of error in SSIS?

Why Duplicate Field LoweredEmail ...?

Apr 21, 2007

Hi,
in table aspnet_membership of ASPNETDB.mdb file, i saw a kind of duplicate field like "LoweredEmail" containing the same value as field "Email" (also in table users field "LoweredUsername" ..).
I guess it's for containing email in lowercase, but why those fields?
Thanks

Trying To Append A Field If An Insert Happens To Contain A Duplicate

Jan 9, 2004

I deliberately intend to add some duplicates to one of my tables. For eg

Job User IsAdmin

JobID 235User ID 1
JobID 235User ID 5
JobID 235User ID 9
JobID 235User ID 5
JobID 235User ID 2
JobID 235User ID 9
JobID 235User ID 10
JobID 235User ID 1

I know its bad practice to do such a thing but there is a genuine reason. What I need to do is to be able to have a SQL statement that appends true to the IsAdmin field whenever it encounters the next UserID thats happens to be a duplicate. Hence the above would look like:

Job User IsAdmin

JobID 235User ID 1
JobID 235User ID 5
JobID 235User ID 9
JobID 235User ID 5 True
JobID 235User ID 2
JobID 235User ID 9 True
JobID 235User ID 10
JobID 235User ID 1 True

Thanks
