Integrity Constraint Error On SQL Server Column With No Constraints
Aug 6, 2007
I have created a simple package to load an Excel Spreadsheet into a SQL Server table. There is a one to one relationship between the columns in the .xls file and the columns in the DB record. I am getting integrity constraint errors when I try to load all numeric data from the spreadsheet (defined as Category General in excel, not defined as numeric but consisting of all numeric characters) into a column defined as (nvarchar(20), not null) in SQL Server Management Studio. There are no constraints on the column.
I have been able to temporarily bypass the offending rows, but I do need to load them into SQL Server. The problem column has a mixture of data, two examples would be: N255, 168050. It's the 168050 value that's causing the Task to bomb. How can I get this loaded into my table ?
I am running the package from within MS Visual Studio 2005 Version 8, Excel is version 2003 (11.8120.8122) SP2
Thanks,
Chris

Hello all.
First of all, I've been a reader of swynk.com for quite sometime now, and I'd like to say 'thank you' to everyone who contributes.
Today, I'm the town moron.. haha I'm having issues with column level constraints. I have a varchar(50) where I want to keep *,=,#,/, .. etc, OUT OF the value input. I don't want to strip them. I simply want for sql to throw an error if the insert contains those (and other characters). The only characters that I want in the column are A-Z and 0-9. However, it's not a set number of characters per insert. It always varies... There has to be an easier way to do this than creating a constraint for every possibilty... Any help would be greatly appreciated.
tia,
Jeremy

Hello,
I am fairly new to SQL, so I have a few questions that may sound odd. First of all, I am trying to restrict users to putting in a three character code as an id item, or their team abbreviation. Here is the table definition:
CREATE TABLE TEAMS{
city varchar(20) NOT NULL,
name varchar(20) NOT NULL,
id varchar(3) NOT NULL};
Here is my code for adding the constraint
ALTER TABLE TEAMS
ADD CONSTRAINT Chk_id CHECK (id = `[A-Z][A-Z][A-Z]`);
Here is the error that I get when trying to execute this statement:
Msg 547, Level 16, State 0, Line 1
ALTER TABLE statement conflicted with COLUMN CHECK constraint 'Chk_id'. The conflict occurred in database 'statbookdb', table 'cabateams', column 'id'.
I am using SQL 2005 EM if this makes any difference.
My other question is in regards to once the constraints have been put in. Is there a way to make SQL throw a message out when a user violates a constraint? Right now, I have a numerical constraint in and whenever I violate it, all that happens is a "This page cannot be displayed" error. It doesn't make sense if you can only do this on the front end, as I don't see the point in enforcing it on the backend if there is no way to notify the user.
Thank you all in advance!

Two ways to do this... Creating the constraints when creating the data model OR using SQL to use the 'reference' constraint. Does 2005 provide any other automated method of creating the Primary Key - to Foreign key constraints without writing the SQL to do this?
Thx

Hi,
We will be using SQL Compact Edition in our application. We are doing some tests to make sure that SQL Compact is suitable for our requirments.
Our problem is with Primary keys and how to maintain data integrity since we will have 100+ clients inserting, updating, and synchronizing with SQL Server.
Can we control Identity range?
Shall we use UniqueIdentifires insted of int?
How can we detect errors at the client side? (For example, if two clients are trying to synchronize 2 columns with the same primary key value)
We will use Merge replication.
Thank you

Using the new referential integrity constraints that will be made available, will it allow us to manually define the relationships between entities even if there is no true foreign key constraints setup in the database?
Lets say we deleted the FK_Orders_Customers in Northwind between orders and customers.
Or is this ability available now?
Thank for your time.

I have the need to remove a constraint on a table since I'm trying to alterthe datatype of one of the columns. I know I can drop the constraint giventhe name, but since the name is auto generated (something likeDF__WHRPT_ITV__Expor__45F365D3)I need a way to find this constraint name so that I can programmaticallyremove it.I can get the name using sp_helpconstraint on the table, but can'tseem to locate where the actual constraint_name is stored.This is on SQL 2000.Any help is appreciated.Thanks,-Gary

Error information:
NativeError: 28549
HRESULT: -2147217873
Message: OrdersHeader,Delete,{0503BF00-BB05-11C6-8000-36BC4ADEE342}
Description: The row update or insert cannot be reapplied due to an integrity violation.
Server side: SQL Server 2000 or MSDE
Client side: SQL Server CE or SQL Mobile
This error is usually caused because of an error on the filters. But not in this case, i think.
I assume it's not a filter error because if I delete the SDF and run the sync it works.
The error occurs when I delete some rows in the server (parent(OrdersHeader) and child(OrderLines) tables) and the PocketPC stills have this rows.
On the next synchronization It seems that replication process tries to delete the OrdersHeader rows before the OrderLines rows.
Is there any way to control the synchronization updating order? Or Is there any know issue about this?
It doesn't occur always but it occurs often. And I still haven't found the way to replicate the error.

Hi,
On my aspx Web page, I want to delete a member from database table 'tblMember', but if this MemberID is used as FK in another table, I want to display a user friendlier message like "You cannot delete this member, ....." I am using Try, Catch blocks in my Web Page.
Currently it display this message:
"DELETE statement conflicted with COLUMN REFERENCE constraint 'FK_..._....' The conflict occurred in database '...', table 'tblMembers', column 'MemberID'. The statement has been terminated. "
So how should I precisely trap this error? Does anybody know what Exception is it? or what error number in SQL server?
Thanks

Hi All,
I am inserting into a table that hold several foreign keys from several tables.
I'm performing this via a client (VB) and I only how to capture the error, but unable to determine which column/field is the one that violates referential integrity.
Any one can shed some light here? Many thanks!

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?

We have a database where many tables have a field that has to be lengthened. In some cases this is a primary key or part of a primary key. The table in question is:-
/****** Object: Table [dbo].[DTb_HWSQueueMonthEnd] Script Date: 09/25/2014 14:05:09 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[DTb_HWSQueueMonthEnd](
[Code] ....
The script I am using is
DECLARE@Column varchar(100)--The name of the column to change
DECLARE@size varchar(5)--The new size of the column
DECLARE @TSQL varchar(255)--Contains the code to be executed
DECLARE @Object varchar(50)--Holds the name of the table
DECLARE @dropc varchar(255)-- Drop constraint script
[Code] ....
When I the the script I get the error message Could not create constraint. See previous errors.
Looking at the strings I build
ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] DROP CONSTRAINT PK_DTb_HWSQueueMonthEnd
ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] Alter Column [Patient System Number] varchar(10)
ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] ADD CONSTRAINT PK_DTb_HWSQueueMonthEnd PRIMARY KEY NONCLUSTERED ([Patient System Number] ASC,[Episode Number] ASC,[CensusDate] ASC)
WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
They all seem fine except the last one which returns the error
Msg 8111, Level 16, State 1, Line 1
Cannot define PRIMARY KEY constraint on nullable column in table 'DTb_HWSQueueMonthEnd'.
Msg 1750, Level 16, State 0, Line 1
Could not create constraint. See previous errors.
None of the fields I try to create the key on are nullable.

I have about 100 databases which yeterday had the wrong ddl for a column added, we have a simple cursor that loops through all databases on the server and runs the sql statement.
The following was run
ALTER TABLE salesrep ADD newCol bit DEFAULT 1
Problem is that it should have been this (and preferably have had a named constraint):
ALTER TABLE salesrep ADD newCol bit NOT NULL DEFAULT 0
Problem is now i dont know the names of the contraints they have random hex on the end "The object 'DF__SALESREP__newCol__5BCD9859' is dependent on column..."
How do i just drop this column with ANY constraints on it?,
I really dont want to go through the databases 1 by 1 and look up the constraint name then drop the constraint, then drop the column so i can add it in correctly.
I wish the following would just work.
ALTER TABLE salesrep ALTER COLUMN newCol bit NOT NULL Default 0

Hello:
I tried to do the merge replication between SQL 2000 database and the SQL mobile server on PDA with SQL server management studio from SQL 2005 and I have already successfully synchronized my PDA with one small SQL server database file. However when I tried to synchronized my PDA with another larger SQL server database file, I got the error on PDA as following: €œThe row operation cannot be reapplied due to an integrity violation. Check the publication filter. [Table = AuditCriterion, operation = Insert, RowGuid = {1ee9321d-f00d-410c-8d5b-08d4220d2627}]€?. I have keep checking the size of sdf file during synchronization, I found after the size of the sdf file stop increasing for about 20 mintues, then I got the error above. Morever, AuditCriterion table have a foreign key with another table AuditElement and I have not used publication filter at this stage.
Please help thanks.

Greetings:I have to do a one-off forceful change of some data in a database. Ineed to disable some FK constraints, make the data change, and thenre-enable the constraints.My process will be:ALTER TABLE TABLE1 NOCHECK CONSTRAINT FK_TABLE1_TABLE2UPDATE TABLE1 SET COLUMN1=2 WHERE COLUMN2='Problem row'ALTER TABLE TABLE1 CHECK CONSTRAINT FK_TABLE1_TABLE2I wanted to get some evidence that the constraints were back up after Idid the 'check constraint' statements, so I looked in sysobjects.There's a status column for the constraints, but I can't make muchsense of the numbers. Most of the FK constraints that I have notchanged are of status 0, but when I NOCHECK a constraint, it goes to2304. When I CHECK it again, it's 2408.Can someone explain this, and suggest a way to double-check that myconstraints are in fact enabled once I run the CHECK statement?Thanks!!

Hi gurus:
I met a very strange problem recently. I set up a database integrity check maintenance plan. But this job failed every time. I looked into the logs, the error message was that Databases that have a compatibility level of 70 (SQL Server version 7.0) will be skipped. I used the sp_helpdb to check the version of the databases included in my maintenance plan. The sp result shows that all the databases are above version 80....
Even more strange, i can successfully run the dbcc check query on each database.
Any comment and suggestion will be very appreciated.

How can you indicate that a FOREIGN KEY constraint references twocolumns in two different tables?"SQL Server Books Online" show an example of how to reference twocolumns in the SAME table:REFERENCES ref_table [ ( ref_column [ ,...n ] )Here is the error and the 'bad' SQL code:Server: Msg 8148, Level 16, State 1, Line 4More than one column FOREIGN KEY constraint specified for column'UserOrGroupId', table 'salesforce3.dbo.AccountShare'.CREATE TABLE salesforce3.dbo."AccountShare" ("Id" varchar(18) PRIMARYKEY , ... , "UserOrGroupId" varchar(18) CONSTRAINTFK_UserOrGroupId6349 FOREIGN KEY REFERENCES "User"(Id) REFERENCES"Group"(Id) , ... )

I know this is probably a flick of a switch but I cannot figure out which switch. Setup is SQL Server / Stored Procedures / DAL / BLL(skipped for testing) / PL. The stored procedure queries from only one table and two columns are ignored because they are being phased out. I can run the stored procedure and preview the data in the DAL but when I create a page with an ODS linked to the DAL and a GridView I get this error. I checked every column that does not allow nulls and they all have values. I checked unique columns (ID is the only unique and is Identity=Yes in the table definition). I checked foreign-key columns for values that are not in the foreign table and there are none. Any ideas why do I get this?
Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.

Hi,
I am getting the above error when trying to load a report into my Web Application, I have tracked the error down to one specific field in my database. Even though this field is a NVarChar field and is of size 30 it would seem that there is an issue returning the value from the field. I can write it into the database no problems but when I try to get it out of the database it returns the above error.
e.g
MOB 401.908.804 - Fails
0401.907.324 - okay
8239 9082 (pager) - fails
Anyone got an idea on how to fix this????
Regards..
Peter.

Hmm,
I'm creating a table that contains information from two other tables. I'd like to have a constraint on some columns so that thay can only contain information that exists in the other two tables. This is what I got:
create table dbo.KUSE_Bills
(
SERVICE_ID int IDENTITY(1,1) NOT NULL primary key,
BILLDATE datetime NOT NULL,
CNAME varchar(100) NOT NULL,
SNAME varchar(100) NOT NULL,
PRICE money NOT NULL,
UNIT varchar(50) NOT NULL,
NUMBER integer NOT NULL,
BILLSUM money NOT NULL
)
GO
I tried something like this:
create table dbo.KUSE_Bills
(
SERVICE_ID int IDENTITY(1,1) NOT NULL primary key,
BILLDATE datetime NOT NULL,
CNAME varchar(100) NOT NULL,
SNAME varchar(100) NOT NULL,
PRICE money NOT NULL,
UNIT varchar(50) NOT NULL,
NUMBER integer NOT NULL,
BILLSUM money NOT NULL
CONSTRAINT chk_cname CHECK (CNAME NOT IN (
SELECT CNAME FROM KUSE_Customer))
)
GO
But subqueries are not allowed...
So how can I do it?

I like to use the management console to design tables, but have
been unable to figure out how to add a unique column constraint.
I have a primary key defined in col1 and want to make col2, char(10),
unique, but keep col1 as the primary key.
I have tried the Check constraint menu path, but do not know how
to write the expression.
If I go along the Indexes/Key path, I am forced to change the primary
key which I do not want to do.
Can anyone help?

Thanks in advance!

Hi.
I was wondering how I should go about doing this thing. I need to put a value in a column that is based on values on other columns in the same row.
When this statement executes I need to put a value in Col3.
insert into myTable(Col1, Col2)
values(25, -14)
Something like so:
if(Col1 >0 AND Col2 <0)
set Col3 = Col1 - Col2
else
set Col3 = Col1;
I don't now quite how to solve this. I am really going to need this value in a column. Calculating the value at retrieval is not on option...
I appreciate all help. I'm using SQL Server 2005.
Thanks!

I can't seem to get the syntax correct for ALTERing an existing column with a default constraint. I've been to Help and BOL. There are examples that show how to use the ALTER command to add a column with a default constraint but not how to do it on an existing column.
Any help would be appreciated.
