Inserting Of Duplicate Records Error Message
Jan 15, 2004
I would like to know what options I have with regards to trapping a duplicate record
before it tries to post to a SQL database. I have set the column to unique in SQL. But
when I try to use ASP and post a duplicate record I get a system error. I would like to
just create a referential error to notify the user that they cannot post a duplicate record
please try again. Any help would be greatly appreciated.

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"); }

Have a table that is used during a conversion. It is hit pretty heavily with inserts by mulitple session ids. For performance reasons I cannot add a unique constraint on the column that is getting duplicates (it is an encrypted cell in varbinary).
I do not want duplicates in this Encrypted Column. So before each insert the insert programs reads the table and verifies that the Encrypted Column value does not already exist. But unfortunately several duplicates are falling through the cracks. What are my options for not allowing duplicates?

I have a web app that calculates tax filing status and then stores data about the person.
Facts
The insert is done through a stored procedure.
All the sites that this program is being used are connecting through a VPN so this is not an external site.
The duplicate records are coming from multiple sites (I am capturing there IP address).
I am getting a duplicate about 3 or 4 times a day out of maybe 300 record inserts.
Any help would be greatly appreciated.
There are many sqlcmdInsert.Parameters("@item").Value =
cnTaxInTake.Open()
sqlcmdInsert.ExecuteNonQuery()
cnTaxInTake.Close()
And that is it.

Hi All, I have a web form that inserts information into two tables in sql 2005 database on a submit button click. I have a unique key on the tables preventing duplicate information which works fine. The problem I have is that at the minute if a users tries to insert a duplicate row they just get the built in sql error message. Is there a way I can validate the information before if goes into the database and display perhaps a label telling the user of their error or is there a way I can customize the build in sql error message? I've had a search on various forums and sites and can't find any info that would help me. Thanks in advance

My problem is that the 'INSERT INTO' query that sends the records to thetable is dynamically compiled in VBA and and the target table has a twocolumn primary key. I have made a number of attempts at getting 'WHERENOT EXISTS' to cure the problem but so far without success and previouspostings have resulted in advice to create an 'ignore duplicates' index.This solved the problem in asmuch as it allowed the SQL to insert the records that did not alreadyexist but resulted in the message appearing every time the user ran thethe query. Whilst this is not a major problem it is vaguely irritatingand I would like to find a way to stop it happening. I suspect that thesolution may involve using the @@ERROR command but I am not sure of thesyntax.RegardsColin*** Sent via Developersdex http://www.developersdex.com ***

This is probably a silly question to most of you, but I'm in the processof splitting off years from a large DB to several smaller ones. Some ofthe existing smaller DBs already have most of the data for theirrespective years. But some of the same data is also on the source DB.If I simply do an insert keying on the year column, and a row beinginserted from the source DB already exists in the target DB, will aduplicate row be created?And if so, how can I avoid that?Thanks,John Steen*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!

I have a table storing only 2 FKs, let's say PID, MID
Is there any way that I can check distinct data before row is added to this table?
For example, current data is
PID MID------------100 2001100 2005101 3002102 1009102 7523102 2449
If my query is about to insert PID 100, MID 2001, since it's existing data, i don't want to add it. Can I use trigger to solve this issue?
Thanks.

Hi I am trying to insert entries in a table which has a composite primary key and i am inserting it on UID basis.
INSERT INTO TABLE_B (TABLE_B_UID,NUM_MIN, NUM_MAX,BIN, REGN_CD, PROD_CD, CARD)
(SELECT UID,LEFT(NUM_MIN,16),LEFT(NUM_MAX,16),BIN, REGN_CD, PROD_CD, CARD FROM TABLE_A WHERE UID NOT IN (SELECT TABLE_B_UID FROM TABLE B))
When i insert it tries to insert a duplicate entries and gives me an error. Since I am new to SQL SERVER 2000 i need some help. I tried IF NOT EXISTS, EXCEPT but i guess i am wrong at the syntax.
Can anybody help me out?

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

Hi there, newbie here.
I'm building a web application that allows for tagging of items, using ASP.NET 2.0, C# and SQL Server.
I have my USERS, ITEMS and TAGS separated out into three tables, with an intersection table to connect them.
Imagine a user has found an item they are interested in and is about to tag it. They type their tag into a textbox and hit Enter.
Here's what I want to do:
I want to search the TagText column in my TAGS table, to see if the chosen tag is already in the table. If it is, the existing entry will be used in the new relationship the user is creating. Thus I avoid inserting a duplicate value in this column and save space. If the value is not already in the column, a new entry will be created.
Here's where I'm up to:
I can type a tag into a textbox and then feed it to a query, which returns any matches to a GridView control.
Now I'm stuck... I imagine I have to use "if else" scenario, but I'm unsure of the code I'll have to use. I also think that maybe ADO.NET could help me here, but I have not yet delved into this. Can anyone give me a few pointers to help me along?
Cheers!

Why does this code tell me that I inserted 2 rows when I really only inserted one? I am using SQL server 2005 Express. I can open up the table and there is only one record in it. Dim InsertSQL As String = "INSERT INTO dbCG_Disposition ( BouleID, UserName, CG_PFLocation ) VALUES ( @BouleID, @UserName, @CG_PFLocation )"Dim Status As Label = lblStatus
Dim ConnectionString As String = WebConfigurationManager.ConnectionStrings("HTALNBulk").ConnectionString
Dim con As New SqlConnection(ConnectionString)
Dim cmd As New SqlCommand(InsertSQL, con)
cmd.Parameters.AddWithValue("BouleID", BouleID)
cmd.Parameters.AddWithValue("UserName", UserID)
cmd.Parameters.AddWithValue("CG_PFLocation", CG_PFLocation)
Dim added As Integer = 0
Try
con.Open()
added = cmd.ExecuteNonQuery()
Status.Text &= added.ToString() & " records inserted into CG Process Flow Inventory, Located in Boule_Storage."
Catch ex As Exception
Status.Text &= "Error adding to inventory. "
Status.Text &= ex.Message.ToString()
Finally
con.Close()
End Try Anyone have any ideas? Thanks

Ok, I'm really new at this, but I am looking for a way to automatically insert new records into tables. I have one primary table with a primary key id that is automatically generated on insert and 3 other tables that have foreign keys pointing to the primary key. Is there a way to automatically create new records in the foreign tables that will have the new id? Would this be a job for a trigger, stored procedure? I admit I haven't studied up on those yet--I am learning things as I need them. Thanks.

Yes, I know this subject has been exhausted, but I need help in locating the discussion which took place a few months ago.
Sharon relayed to the group a piece of software (expensive) which would help in my particular situation. I grabbed a demo and have gotten the approval for purchase. Unfortunately, I don't have the thread with me at work.
The problem:
Number Fname Lname Age ID
123 John Franklin 43 1
123 Jane Franklin 40 2
123 Jeff Franklin 12 3
124 Jean Simmons 39 4
125 Gary Bender 37 5
126 Fred Johnson 29 6
126 Fred Johnson 39 7
127 Gene Simmons 47 8
The idea would be to get only unique records from the Number column. I don't care about which information I grab from the other columns, but I must have those fields included.
If my resultant result set looked as follows, that would be fine. Or any other way, as long as all of the fields had information and there were only unique values in the Number field.
Number Fname Lname Age ID
123 Jeff Franklin 12 3
124 Jean Simmons 39 4
125 Gary Bender 37 5
126 Fred Johnson 39 7
127 Gene Simmons 47 8
If anyone remembers this discussion, mainly the date, I would really appreciate it.
Thanks

I have two tables, one contains all work orders, the second contains records on work orders that are linked to customoer orders. I'm trying to create a query that will return specific fields from the table that contains orders in the linked order table, and only the work orders in the all order table that (work_order) do not exist in the linked order table (demand_supply_link). I have tried several queries and cannot get the results I desire. Here is the query I am currently trying.
SELECT DISTINCT WORK_ORDER.DESIRED_WANT_DATE as 'Want Date', DEMAND_SUPPLY_LINK.SUPPLY_BASE_ID as 'WO Id',
WORK_ORDER.DESIRED_QTY as 'End Qty', DEMAND_SUPPLY_LINK.SUPPLY_PART_ID as 'Part Id', CUST_ORDER_LINE.CUSTOMER_PART_ID as 'Cust Part',
OPERATION.RESOURCE_ID as Resource, PART.DESCRIPTION as Description, CUSTOMER.NAME as Name
FROM ((((DEMAND_SUPPLY_LINK INNER JOIN CUST_ORDER_LINE ON DEMAND_SUPPLY_LINK.DEMAND_BASE_ID = CUST_ORDER_LINE.CUST_ORDER_ID)
INNER JOIN WORK_ORDER ON DEMAND_SUPPLY_LINK.SUPPLY_BASE_ID = WORK_ORDER.BASE_ID)
INNER JOIN OPERATION ON WORK_ORDER.BASE_ID = OPERATION.WORKORDER_BASE_ID) INNER JOIN PART ON WORK_ORDER.PART_ID = PART.ID)
INNER JOIN (CUSTOMER INNER JOIN CUSTOMER_ORDER ON CUSTOMER.ID = CUSTOMER_ORDER.CUSTOMER_ID) ON CUST_ORDER_LINE.CUST_ORDER_ID = CUSTOMER_ORDER.ID
WHERE WORK_ORDER.DESIRED_WANT_DATE Is Not Null AND OPERATION.RESOURCE_ID in ('ASSY','FAB 1','PLAY TRK')
AND WORK_ORDER.STATUS='R'
UNION
SELECT distinct work_order.desired_want_date as 'Want Date', work_order.BASE_id as 'WO Id',
work_order.desired_qty as 'End Qty', work_order.part_id as 'Part Id', operation.resource_id as Resource,
part.description as Description
FROM WORK_ORDER INNER JOIN PART ON PART_ID=WORK_ORDER.PART_ID INNER JOIN OPERATION ON WORK_ORDER.BASE_ID=OPERATION.WORKORDER_BASE_ID
WHERE WORK_ORDER.DESIRED_WANT_DATE IS NOT NULL AND OPERATION.RESOURCE_ID IN ('ASSY','FAB 1', 'PLAY TRK')
AND WORK_ORDER.STATUS='R'
This is the error I receive:
Server: Msg 205, Level 16, State 1, Line 1
All queries in an SQL statement containing a UNION operator must have an equal number of expressions in their target lists.
The all orders table (work_order) will not have the other fields to link to as there is no customer order linked to them.
Can anyone help. Thanks!

Hi,
Not so sure how simple this question is but here is what happened. I installed SQL Server 2005 on a new Win Server 2003. I exported the tables and their data from the old machine to the newly established database on the new machine.
It looks like all my records were duplicated. When I try to delete one of the duplicates it won't work because both rows are effected. I can't set my primary key now and if I try to create a new database with the primary key already set than the import fails.
Any one run into this before or know what's going on?
Any help ASAP would really be appreciated.
Thanks,
Alice

Hi,I have written a web application using dreamweaver MX, asp.net, and MSsql server 2005.The problem I am having occurs when I attempt to edit a record. I have setup a datagrid with freeform fields so that the user can click on edit, make the required changes within the data grid then click update. The data is then saved to the database. All this was created using dreameaver and most of the code was automatically generated for me.The problem is that, not everytime, but sometimes when I go to edit a record once I hit the update button to save the changes the record is duplicated 1 or more times. This doesnt happen everytime but when it does it duplicates the record between 1 and about 5 times. I have double checked everything but cannot find anything obvious that may be causing this issue. Does anyone have any suggestions as to what I should look for? Is this a coding error or something wrong with MSsql? Any ideas?Thanks in advance-Mitch
