i have the following step in a stored procedure
Alter table ABC
Add constraint Primary_KEY_ABC
PRIMARY KEY (DATE, Amount)
but i get the error primary key already exists.
So is there any way I can generate a unique name everytime I run the
proc, its runs only once a day so can i use getdate() in the name somehow. is it possible.

Hi,
I'm testing performance of OPENROWSET,
I executed OPENROWSET 3 times in a sequence. But in Profiler i see only following events..
Audit Login
Batch Started
Batch Completed
RPC:Completed.
RPC:Completed.
:
:
:
:
RPC:Completed.
I'm intersted only to see if the login happens three time, but i'm not able to see that. Also, there was no Audit Logout.
Does SQL Server automatically pool connections ?
If i run Openrowset 3 times, shouldn't it open & close connection 3 times ?
Please clarify.
Thanks.

When I open a report definition, go to a dataset and open it, the CommandType ALWAYS goes to "Text". I don't want "Text", I want "Stored Procedure". I NEED "Stored Procedure".
I have also found that the CommandText for a different dataset will change even though I have not opened it.
I guess the only solution I have is to open the RDL files, search for the dataset entries and then fix the XML code. This is a real pain in the buttocks when I am working with 300+ reports.
Is there a fix for this bug? Or are you going to FORCE everyone to use "Text"?
I am trying to finish this project so that we can release it to our customers but now I have to wonder why we decided to go with Reporting Services, especially now that we have to do double edits on each and every report.

In my SSIS package I have a text file source that I am mapping to a destination table. I have an error component that logs any row level errors and have noticed that it is not logging the correct field. I know this because I have a few different sources that submit the same files and have looked at the source of both. THE ONLY DIFFERENCE in the one that works versus the one that does not is that 2 of the 25+ columns are switched. I would not think this would matter because field A in the text file is mapped to field A in the database.
Does the order in which the fields come into the SSIS package matter?
Thanks
Every time I execute DBCC DBREINDEX (Table_Name, '',0)WITH NO_INFOMSGS the server hangs. No error messages in windows 2000 logs or in the SQL 7.0 logs.
The table is about 2 gig in size and the index is a clustered index on two fields.
The server has 1 gig of memory and the cache hit ratio, and cache flushes both look good. Any ideas? Any help would be greatly appreciated.
Hi All,
I am trying to execute a package (programmatically) that is stored on my local disk using the information that is provided on the following page:
http://msdn2.microsoft.com/en-us/library/ms136090.aspx
This means, I am using the Application object and the Package object to actually load the package using the path to it.
So my code looks something like this:
-----
pkgLocation = @"<package_path>/Package1.dtsx";
app = new Application();
pkg = app.LoadPackage(pkgLocation, null);
pkgResults = pkg.Execute();
Console.WriteLine(pkgResults.ToString());
Console.ReadKey();
---
My package reads in a flat file (located on another server) and transforms it and saves it to a database (on that same server). And mind you, I can execute this package just fine when I do it manually from within BIDS.
But when I try to execute the above mentioned code in my C# solution (compiled to a command line executable), I always get a "Failure".
Can somebody point out what I am doing wrong here?
Thank you in advance,

Hi guys, Im desperately hoping someone here can help me. Ive been trying to set up merge replication between 2 servers all weekend and it keeps failing. Im setting this up as follows
The Publisher/Distributor is a SQL Server 2005 machine, the database being replicated is 4gb, and the only subscriber is a SQL Server 2000 SP4 machine. I set up my publication normally, and set up the push subscription, adn set it to initialize immediately. It weill then start bulk copying and go on for about 3-4 hours before it fails and gives me the errors:
Error messages:

This is driving me crazy as I havent slept in ages trying to get this fixed. Anyone have any idea whats going on? Its always one of 2 tables so far that keep failing, ContactLog and Content, what can I do?
Why does Error log show database restarting everytime a transactionlog backup runs?It also runs a checkdb as well.The log backups are scheduled through a maintenance plan.Is this normal?

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.
Please help everytime i call http://servername/reportserver it is presenting the login screen, if i enter the username and password then i can access the reportserver screen, same with reportmanager tool.
under iis manager for the reportserver virtual directory i have given anonymous login access.
do i have to set any other extra permissions other than anonymous login(iusr_machinenname)
thank you all for the information.
i have an SSIS package that exports to an excel file. This works fine. the problem is that it appends the data instead of overwriting the file. Is there any way to overwrite the file like you can with a flat file? I have to email the file everyweek and don't want to have to clear it out manually. Any help would be appreciated
View 2 Replies View RelatedWe 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?
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. What do you think?
thanks

using alter table syntax how can i insert the field TramingChoiceCd
Extend the constraint on NetwkChannel table UQ__TetwkChannel__50FB042B to include TramingChoiceCd
Which is the preferred method Rule, Check Constraint or Trigger?
I want to set a column to todays date when the column is = "T"
else when "F" set it to a future date. Each time there is a insertion into
the table.
I have a varchar field in a table.I want to restrict the entries in that field as "yes" or "no" nothing else.No record will be allowed for this field without yes or no.My question is is it possible without using any trigger for the table?I want to do it with the help of a constraint.

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

View 1 Replies View RelatedMy 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?
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

Hello, I have hit the wall here...can't make sense of this one.
I have a script that creates a PRIMARY KEY constraint called PK_tblDRG
CODE:
ALTER TABLE [dbo].[tblDRG]
ALTER COLUMN [record_id] Uniqueidentifier NOT NULL
Go
ALTER TABLE [dbo].[tblDRG]
WITH NOCHECK ADD PK_tblDRG PRIMARY KEY CLUSTERED
(
[record_id]
) WITH FILLFACTOR = 90 ON [PRIMARY]
All is fine with that. 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. Looks like the IF statement didn't do it's job. Ok fine. I'll just kill it myself:
ALTER TABLE [dbo].[tblDRG] DROP CONSTRAINT PK__tblDRG
AND I GET THIS?!?!?!?!
Server: Msg 3728, Level 16, State 1, Line 1
'PK__tblDRG' is not a constraint.
What am I not getting here? Is it me...I can take If I am a bone head here.
Any help would be appreciated. Thanks!
Suppose I have a table called "Languages" with two fields. One field is an Identity field that acts as the Primary Key. The second field is "LanguageName" which would naturally be "English", "Spanish", etc. What I want to do is put a constraint on the LanguageName field so that someone cannot enter the same name twice.Is it better to create an Index --> Create UNIQUE and use:a) Constraint?b) Index with Ignore duplicate key checked?Is there any benefit of one over the other for my purpose? Thanks.
