Catching Violation Of UNIQUE KEY Constraint In Stored Procedure
Dec 20, 2005
Dear All,
I have a stored procedure which bulk inserts records into a table based on a passed in variable that contains comma separated values of record Ids.
However I have a constraint on the table ensuring that value-pairs in 2 columns must be unique (as a person can not be twice on the same project)
Since I insert the passed in person Ids in a loop, I’d like to catch if this constraint has been violated and skip that specific cycle if it has but do commit the rest.
Not sure if this can be done, and if yes could someone let me know the SQL syntax and structure please?
Am I explaining this clearly?
Thanks in advance all comments are much appreciated!
The following SP causes the error "Violation of UNIQUE KEY constraint 'AlumniID'. Cannot insert duplicate key in object [table name]. The statement has been terminated." AlumniID is the table's PK and is set to autoincrement. I'd appreciate any help or suggestions.

I'm retreiving data from a SAP BW data source. In the dataset designer I can build a query that returns a single value, the data returns successfully in the designer. When I switch to the layout mode I can place the field of the datset in table / matrix / textbox. However when i switch to preview mode or deploy the report and try to see them in Report Manager the report fails to render with the following message:
Query Execution Failed for dataset 'XXX'
These columns don't currently have unique values.
Its a single cell datset?!?!
I can successfully retreive data from other SAP Infocubes and queries. I also cannot replicate the error using a SQL Server datasource. The stack trace error looks like this:
w3wp!processing!6!5/9/2007-16:57:41:: e ERROR: Throwing Microsoft.ReportingServices.ReportProcessing.ReportProcessingException: Query execution failed for data set 'DataSet1'., ; Info: Microsoft.ReportingServices.ReportProcessing.ReportProcessingException: Query execution failed for data set 'DataSet1'. ---> System.ArgumentException: These columns don't currently have unique values. at System.Data.ConstraintCollection.AddUniqueConstraint(UniqueConstraint constraint) at System.Data.ConstraintCollection.Add(Constraint constraint, Boolean addUniqueWhenAddingForeign) at System.Data.DataTable.set_PrimaryKey(DataColumn[] value) at Microsoft.ReportingServices.XmlaClient.CubeMetadataCache.CreatePrimaryKeys(DataTable table, InternalObjectType objectType) at Microsoft.ReportingServices.XmlaClient.CubeMetadataCache.Populate(InternalObjectType objectType) at Microsoft.ReportingServices.XmlaClient.CubeMetadataCache.Microsoft.ReportingServices.XmlaClient.IMetadataCache.Populate(InternalObjectType objectType) at Microsoft.ReportingServices.XmlaClient.ObjectMetadataCache.Microsoft.ReportingServices.XmlaClient.IObjectCache.Populate() at Microsoft.ReportingServices.XmlaClient.CacheBasedFilteredCollection.PopulateCollection() at Microsoft.ReportingServices.XmlaClient.DimensionPropertyCollectionInternal.Find(String index) at Microsoft.ReportingServices.XmlaClient.DimensionPropertyCollection.Find(String index) at Microsoft.ReportingServices.DataExtensions.SapBw.DataReader.FindOptionalPropertyName(String internalColumnName, CubeDef cube, Boolean fIsYukonSP1) at Microsoft.ReportingServices.DataExtensions.SapBw.DataReader.GenerateColumnInformation(CubeDef cube, Boolean fIsYukonSP1) at Microsoft.ReportingServices.DataExtensions.SapBw.DataReader..ctor(AdomdDataReader dataReader, CubeDef cube) at Microsoft.ReportingServices.DataExtensions.SapBw.SapBwCommand.ExecuteReader(CommandBehavior behavior) at Microsoft.ReportingServices.ReportProcessing.ReportProcessing.RuntimeDataSetNode.RunDataSetQuery()
Any ideas why this happening and how I can get around it?
Thanks

ps Why would you want to put a unique constraint on a read only single table dataset?
I have a table with 0 records. When I try to insert records using a SP, it gives the following error. Violation of UNIQUE KEY Constraint 'constraint name'. Cannot insert duplicate key in object 'Objectname'. How do I resolve this. Thanks.
I've read a few different articticles wrt how the handle this error gracefully. I am thinking of wrapping my sql insert statement in a try catch and have the catch be something likeIF ( e.ToString() LIKE '% System.Data.SqlClient.SqlException: Violation of PRIMARY KEY constraint 'PK_PS_HR_Hrs'. Cannot insert duplicate key in object %'){lable1.text = "Sorry, you already have reported hours for that day, please select anothe rdate" } Is there a better way?TIA Dan
Hi AllHere is my SPALTER PROCEDURE dbo.InsertPagerDays @ReportEndDate datetime, @PagerDays int,@UserID varchar(25)ASIF EXISTS(-- you cannot add a pager days more than once per report dateSELECT ReportEndDate, UserId from ReportPagerDays where ReportEndDate = @ReportEndDate and UserId = @UserID)Return 1 elseSET NOCOUNT OFF;INSERT INTO [ReportPagerDays] ([ReportEndDate], [PagerDays], [UserID]) VALUES (@ReportEndDate, @PagerDays, @UserID)RETURNMy Question is, this SP will not let you enter in a value more than once (which is what i want) but how do I write my code to inform the user? Here is my VB code becuase the SP does not error out (becuase it works it acts as if the record updates)How can I catch the Return 1'set parameters for SPDim cmdcommand = New SqlCommand("InsertPagerDays", conn)cmdcommand.commandtype = CommandType.StoredProcedurecmdcommand.parameters.add("@ReportEndDate", rpEndDate)cmdcommand.parameters.add("@PagerDays", PagerDays)cmdcommand.parameters.add("@UserId", strUserName)Try'open connection hereconn.Open()'Execute stored proccmdcommand.ExecuteNonQuery()Catch ex As Exceptionerrstr = ""'An exception occured during processing.'Print message to log file.errstr = "Exception: " & ex.Messagelblstatus.ForeColor = Drawing.Color.Redlblstatus.Text = "Exception: " & ex.Message'MsgBox(errstr, MsgBoxStyle.Information, "Set User Report Dates")FinallyIf errstr = "" Thenlblstatus.ForeColor = Drawing.Color.Whitelblstatus.Text = "Pager Days Successfully Added!"End If'close the connection immediatelyconn.Close()End Try
how to catch batch id from a running stored procedure. My intention is that when we run store procedures in batch we are running a lot of procedures and I would like to log each run and if the same procedure is running several times per day I need to separate the runs by a "batch id" for the specific run. I have created a logtable and a logprocedure that logs the start and end of a procedure run and also some values for the run. So I'm trying to find a way of fetching the "batch id" that the sp is running so I can separate the runs when analyzing the logtable. I have looked at metadata tables and also in the table sys.sysprocesses but I cannot find BATCH ID.
I know what this error means is that you can not insert duplicate primary keys in the table but the thing is I am checking the rows if they do not exist then insert otherwise don't do any thing these are the lines I am writing in my strored procedure can someone please let me know what I am doing wrong here.
If not exists (Select * From GGP WHERE FFECTIVE_DATE =@v_EFFECTIVE_DATE AND ASSET_ID= @v_ASSET_ID AND ASSET_TYPE = @v_ASSET_TYPE AND Value = @v_Value AND hour = @v_Hour)
INSERT INTO GGP (ASSET_ID,ASSET_TYPE,Hour,Value,EFFECTIVE_DATE) values(@v_ASSET_ID,@v_ASSET_TYPE,@v_Hour,@v_Value, @v_EFFECTIVE_DATE)
The exact error is Violation of PRIMARY KEY constraint 'PK_SP_GGP'. Cannot insert duplicate key in object
When I try to insert data into a table (let's just call it MyTable for this post), I suddenly get the following error.
Violation of PRIMARY KEY constraint 'PK_MyTable'. Cannot insert duplicate key in object 'MyTable'.
My table does have a primary key field named 'id', which is an auto-incrementing BIGINT. The last record I successfully inserted received 14 in the id field, so I'm assuming the database is trying to assign 15 to the next. Unfortunately, there is already a record with an id of 15; the next available id is 21.
Is there a way to avoid these primary key collisions?
I'm trying to insert records into a table and getting the below error and not sure how to resolve it:
Server: Msg 2627, Level 14, State 1, Line 1 Violation of PRIMARY KEY constraint 'PK_propertyItem'. Cannot insert duplicate key in object 'propertyItem'. The statement has been terminated.
Violation of PRIMARY KEY constraint 'PK_tbl_others. Cannot insert duplicate key in object 'tbl_others. The statement has been terminated.-- What does it mean i cant load the data to tbl_others
When replication merge, is taking place between two servers on one particular table I keep getting violation of primary key constraint, Does anyone out there have a fix for this?
I thought the whole point of 'check constraint' being unticked meant you could whack your data straight in no probs.
How can I insert a bunch of historical information where I want to control the PK, in this case DealID?
I have got 'keep identity' checked.
I check the db, the Id does NOT exist currently.

I've a set of source tables on one server and a set of destination tables on another. When I move data from one server to next, I get an error saying "Violation of Primary Key Constraint". This happens for only one table among the 6 tables that I have. I dont understand why it throws me this error. Though theres an error for this table, the data from source table moves into this destination table.

I am running merg replication (pull) between 7 various sites and once in a while when two people update information in a table in close proximty in time, I will get a primary key violation when viewing conflicts, it's almost excluslively in one table. What is the best way to handle this error. Should I delete the entire column on the subscriber and let the publisher update the subscriber? Or should I redesing the table and primary keys? Any assistance in the matter would be greatly appreciated.
A UNIQUE INDEX must inherently impose a unique constraint and a UNIQUE CONSTRAINT is most likely implemented via a UNIQUE INDEX. So what is the difference? When you create in Enterprise Manager you must select one or the other.
What's the difference in the effect of the followings: CREATE UNIQUE NONCLUSTERED INDEX and ALTER TABLE dbo.titles ADD CONSTRAINT titleind UNIQUE NONCLUSTERED
I found there're two settings in Indexs/Keys dialog box of the management studio, Is Unique, and Type. The DDL statements above are generated by setting Is Unique to yes plus Type to Index, and just Type to Unique Key, respectively. What's the difference between them?
If there are two different transactions, both of which update the username column to 'xyz' for userid = 234 in 'Users' table. This is a unique value for username. Ater this update each transaction adds a row to 'AppLog' table. The transaction is only committed after second operation. The 'username' column has a unique constraint on it. If transaction isolation level is 'read committed', and both transaction execute the first operation when neither of the transactions have been committed, then the transaction that calls COMMIT later will error out or not? If COMMIT does not check constraints then it will NOT error out. As a result we will have a violation of unique constraint happening without any error being thrown by SQL Server.
In my SSIS package i am loading data from 1 source database to 2 targets database, both targets have same structure and datatype.
My package is working fine for 1 target  database but for 2 nd database its giving error "Violation of PRIMARY KEY constraint" but where as primary key constraint is not violating .
Cannot find an answer to this in previous posting, though there are similar topics.
My primary key "ID" requires a value (is not nullable), and not explictly providing it with one when I update a new record gives the following error:
Cannot insert the value NULL into column 'ID', table 'AdClub.mediaq.News'; column does not allow nulls. INSERT fails. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Data.SqlClient.SqlException: Cannot insert the value NULL into column 'ID', table 'AdClub.mediaq.News'; column does not allow nulls. INSERT fails.
However, trying to stuff that field with a recordCount+1 value (or any value), I get this error:
Violation of PRIMARY KEY constraint 'Primary Key'. Cannot insert duplicate key in object 'News'. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Data.SqlClient.SqlException: Violation of PRIMARY KEY constraint 'Primary Key'. Cannot insert duplicate key in object 'News'.
Cannot figure this one out. The value I'm providing for that field is known to be unique, but the SQL Server spits it out each time.
Is there a way to have the ID primary field automatically update with a new value when a new record is generated? This is how I used to do it in Access, but cannot find a similar feature in SQL Server. I'm sure I'm missing something simple, but right now I'm stuck in this "Catch-22" situation.
We are using SQL CE 3.5 on tablet PCs, that synchs with our host SQL 2005 Server using Microsoft Synchronization Services. On the tablets, when inserting a record, we get the following error: A duplicate value cannot be inserted into a unique index. [ Table name = refRegTitle,Constraint name = PK_refRegTitle But the only PK on this table is RegTitleID.
The table structure is: [RegTitleID] [int] IDENTITY(1,1) NOT NULL, [RegTitleNumber] [int] NOT NULL, [RegTitleDescription] [varchar](200) NOT NULL, [FacilityTypeID] [int] NOT NULL, [Active] [bit] NOT NULL,
The problem occurs when a Title Number is inserted and a record with that number already exists. There is no unique constraint on Title Number. Has anyone else experienced this?
the point here that i have a small table with two fileds, ID (guid) as primerykey RAF(char) and the table is empty when i add a new row i recieve this exception, Violation of PRIMARY KEY constraint 'PK_tblType'. Cannot insert duplicate key in object 'dbo.tblType'. i found no way to solve the problem. thanks in advans
Hi everyone, I need urgent help to resolve this issue... As far as the performance goes which one is better.. Unique Index(col1, col2) OR Unique constraint(col1, col2) ? Unique constraint automatically adds a unique index and unique index takes care of uniqueness then whats the use of unique constraint ?
BOL says a unique constraint is preferred over a unique index. It also states that a unique constraint creates a unique index. What then is the difference between the two, and why is a constraint preferred over the index?
We scheduled lot of SSIS packages on 64 bit server and most of the time they are running fine. Some times we are getting below error message on any random package. When we re-run its working fine to success. This is repeating once in a week on different packages.

Hi i have a stored procedure which deletes a row from a table. Sometimes the proc will break the constraints for the table. How can i check if the constraint is going to be broken before I try to delete so that I can avoid a nasty error message coming onto my asp.net page?
I'm struggling with this one. We have a Street database that can contain multiple entries for one record in our main table. We don't wish to pass duplicate rows back to our end user so I wish to get distinct recno's (the unique identifier for the main table) back from our Street Table.
We have a stored procedure that currently uses Select distinct Recno but I think this is slower than if I used a unique index with ignore_dup_key. Problem is that when I alter the stored procedure it looks like the functionality of the LIKE function is somehow altered. For example Like 'King%' fails to return anything but Like 'King St%' does. I suspect it is the fact that the error "Server: Msg 3604, Level 16, State 1, Procedure" is being generated. How do I code around this server side.
