Named Constraint Is Not Supported For This Type Of Constraint (not Null)
Hi, all.
I am trying to create table with following SQL script:
Code Snippet
create table Projects(
ID smallint identity (0, 1) constraint PK_Projects primary key,
Name nvarchar (255) constraint NN_Prj_Name not null,
Creator nvarchar (255),
CreateDate datetime
);
When I execute this script I get following error message:
Error source: SQL Server Compact ADO.NET Data Provider
Error message: Named Constraint is not supported for this type of constraint. [ Constraint Name = NN_Prj_Name ]
I looked in the SQL Server Books Online and saw following:
CREATE TABLE (SQL Server Compact)
...
< column_constraint > ::= [ CONSTRAINT constraint_name ] { [ NULL | NOT NULL ] | [ PRIMARY KEY | UNIQUE ] | REFERENCES ref_table [ ( ref_column ) ] [ ON DELETE { CASCADE | NO ACTION } ] [ ON UPDATE { CASCADE | NO ACTION } ]
As I understand according to documentation named constraints should be supported, however error message says opposite. I can rephrase SQL script by removing named constraint.
Code Snippet
create table Projects(
ID smallint identity (0, 1) constraint PK_Projects primary key,
Name nvarchar (255) not null,
Creator nvarchar (255),
CreateDate datetime
);
This script executes correctly, however I want named constraints and this does not satisfy me.

Temporarily Dropping Not-null Constraint
I am doing a data conversion in which I drop constraints before inserting data and then reapply at the end. I would like to also drop the not null constraints for certain columns, transfer the nulls and then fill them in later before reapplying the constraints. Is there a relatively simple way to drop and reapply the not null constraints?

What Type Of Constraint To Prevent Duplicates
I am trying to either write a trigger or a check constraint to preventduplicates in my table. There are two columns I need to look at for theduplicates and only one combo value for both columns is allowed in thetable. For e.g.Column Serial can have only one '123456' value with testresult value as'PASS'. This serial can be in the table many times with any other comboso for e.g.The table could contain 100 entries for serial column value '123456'with testresult value 'FAIL', 'PENDING' etc.** TESTED SCHEMA BELOW **-- create tableCREATE TABLE bstresult(ID int IDENTITY (1, 1) NOT NULL ,serial char (10) NULL ,testresult char (10) NULL)-- Insert valid valuesinsert into bstresult values ('123456','PASS')insert into bstresult values ('123456','FAIL')insert into bstresult values ('123456','FAIL')insert into bstresult values ('123456','PENDING')-- insert invalid value this should failinsert into bstresult values ('123456','PASS')If I simply create a unique constraint on both columns it will notallow the FAIL combo or PENDING combo with the same serial which I needto allow.Appreciate your help.

Constraint/identity Which Allows Duplicate Null Fields
hi, I've done Googling and forum hunting but haven't had success finding a simple answer... My table schema is such that it requires the (int) LinkedItemID field to be nullable but still those fields which are set must not be duplicates. I see constraint is out of question and also identity doesn't seem to fit since I'm not using autofill for this particular field. Is there some other way doing this on Sql Server 2005? Thank you.

Unique Constraint Error When There Is No Constraint
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.

Unique Constraint Does Not Permit Duplicate NULL Values
After adding a Unique constraint to a database I cannot add more than one record with a null value for the constrained field. I've tried both adding the constraint to an empty table as well as a table with multiple null values already in the subject field; both efforts have failed. According to BOL SQL-7 allows Unique Constraints on fields with Null values. Am I missing a step? I do need to allow nulls in the field yet ensure that when there is a non-null value it is unique. The SQL statement I've used is: ALTER TABLE tbl_MasterUIC ADD CONSTRAINT uniquesamplenbr UNIQUE NONCLUSTERED (samplenbr) Thanks for any and all suggestions

Stuck Between &"Cannot Insert The Value NULL Into Column 'ID'&" And &"Violation Of PRIMARY KEY Constraint&"
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. Please help!

Hi, I am trying to figure out how to do this. For each row, only one out of two columns(id1,id2) should be populated. So if the id1 column is already populated and the application tries to fill in something for id2 then we just simply don't want to allow that and vice versa. I am thinking triggers is the way to go.

Constraint Help
Hi, i want to put a contraint on a table which much check agains two values in the same column for the same member. For example, i don't want a male to get information based on breast cancer, and i don't want a female to get information based on prostate cancer. I have included some sample data. Just copy and paste. Code Block DECLARE @MemberLookupValues TABLE (OptionID INT, ValueID INT, Description VARCHAR(20)) INSERT @MemberLookupValues VALUES (3, 10, 'Male') INSERT @MemberLookupValues VALUES (3, 11, 'Female') INSERT @MemberLookupValues VALUES (7, 69, 'Prostate Cancer') INSERT @MemberLookupValues VALUES (7, 70, 'Breast Cancer') DECLARE @MemberValues TABLE (MemberID INT, OptionID INT, ValueID INT) INSERT @MemberValues VALUES (1, 3, 10) INSERT @MemberValues VALUES (1, 7, 69) INSERT @MemberValues VALUES (1, 7, 70) INSERT @MemberValues VALUES (2, 3, 11) INSERT @MemberValues VALUES (2, 7, 69) SELECT * FROM @MemberLookupValues SELECT * FROM @MemberValues I've highlighted the values that must be stopped. So the basic check would be, IF OptionID = 3 AND ValueID = 10 then it must not allow you to insert the values OptionID = 7 AND ValueID = 70 I hope that makes sense. Any help will be greatly appreciated, if you need any more informaiton then just ask, Kind Regards Carel Greaves

Constraint Problem
Hi everybody we have the following tables 1) Country Countryid CountyNAme INIndia MYMalaysia UKUnitedKingdom here Countryid is the primary key. 2) MainDept DeptID Deptname Countryid CMCashManagementIN CBConsumerBankingMY CSCustomer SupportIN IBInternetBankIN here deptid is the primary key 3) UserMaster Uid Uname Deptid Countryid 001 Chris CMIN 002 Raja CSIN 003 Ram CBMY here Uid is the primary key. The problem is when i change the countryid from one country to another for a deptname. THe change is not reflected in the usermaster table as it still shows the previous countryid. For eg. user Chris belongs to dept Cash management which is situated in india. Now if i change in mainDept table the cash management from india(IN) to say malaysia(MY).the corresponding change is not reflected in usermaster table.it still shows india. So when i query for chris in usermaster i get an error as i am searching in india for cash mangement. i tried using on update cascade but here it did not work as i have to make DeptID & countryID in MainDept table as composite key & use Deptid & countryid in usermaster as refernce key. Since i have 20-25 tables also referencing the above 2 tables i have to set reference key in all these tables & these tables are in turn referenced elsewhere in other tables. Thus i end up creating a large no. of composite keys. IS there any other way to solve this problem? note : In sqlserver we can give on update cascade still it has the above problem but in Oracle on update cascade is not possible Can anybody suggest a solution for this in both sql server and in oracle Thanks u verymuch

I run this to verify: EXEC sp_pkeys @table_name = 'tblDRG' ,@table_owner = 'dbo' ,@table_qualifier = 'Relational_05Q3' which returns this: TABLE_QUALIFIERTABLE_OWNERTABLE_NAMECOLUMN_NAMEKEY_SEQPK_NAME Relational_05Q3dbotblDRGrecord_id1PK_tblDRG Now I want to drop the constriant if it exists: if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[PK__tblDRG]') and OBJECTPROPERTY(id, N'IsPrimaryKey') = 1) ALTER TABLE [dbo].[tblDRG] DROP CONSTRAINT PK__tblDRG AND I get this in return: The command(s) completed successfully. So, lets double check: EXEC sp_pkeys @table_name = 'tblDRG' ,@table_owner = 'dbo' ,@table_qualifier = 'Relational_05Q3' AND I STILL GET THIS: TABLE_QUALIFIERTABLE_OWNERTABLE_NAMECOLUMN_NAMEKEY_SEQPK_NAME Relational_05Q3dbotblDRGrecord_id1PK_tblDRG Hmmmmm.

Constraint Question
My company does medical billing for several clients. Each client may have a contract with several insurance companies (Payors) for rates for different procedures. I have a table named FeeSchedule with four (relevant) columns: Client, CPTCode (procedure code), Payor, and Fee. Some Payors don't really negotiate, and have the same FeeSchedule for all clients. I know the right way to track that is have a separate set of records for each client, even for payors like medicare where every client will have the same set of records. However, the data-entry burden for populating that table would be very large, and I would like to use be able to have use a NULL client like a wildcard. The problem is I then can't use client as part of the key, and I need to be able to restrict it so that if I have a NULL client for a specific CPT and Payor and I can't also have a another Client for that CPT and Payor. Any ideas how to accomplish this or the equivalent functionality?

Precedence Constraint Being Ignored?
hi all - this is the first time i've worked with SSIS / Business Intelligence, and I'm having an issue with a piece of basic functinoality. I'm working with some dtsx jobs which were all conversions from Sql Server 2000 DTS jobs. The conversion process "seemed" to go smoothly. I used the Migration Wizard, and it successfully converted my outputted DTS job files into DTSX files. In the Business Intelligence design environment (Control Flow) for a specific dtsx package, I have two tasks that are linked together by a Precedence Constraint. * Task A Truncates all data in Database B --> Table A * the precedence constraint says that if Task A is successful, then go on to Task B (or at least i think it does) * Task B copies the newest data from Database A --> Table A over to Database B --> Table A Everything appears to be correct, but if i right-click Task A and perform an "Execute Task" command, Task A will run successfully, but then stops short without running Task B. Are there any common "gotchas" or issues that I might be missing which would cause this behavior? I deleted the existing precedence constraint, and added back a new one with the same settings, but Task B still will not run. thanks for any help on this

Hi, Suppose the following table definition in Sql Server 2005, create table CompanySymbol CompanyId int, SymbolId int, IsPrimarySymbol bit Primary Key (CompanyId, SymbolId) How can I create a constraint which wil ensure that IsPrimarySymbol will be set to 1(true) only once per CompanyId while allowing it to be set to 0 an unlimited amount of time per CompanyId. i.e.: CompanyId SymbolId IsPrimarySymbol ----------------------------------------------------------- 1 1 1 (IsPrimarySymbol to 1 for CompanyId 1) 1 2 0 1 3 0 2 1 1 (IsPrimarySymbol to 1 for CompanyId 2) 2 2 0 3 1 0 4 1 1 (IsPrimarySymbol to 1 for CompanyId 4) 4 2 0 4 3 0 Thanks
