I need to make some changes to tables in a database. To do this requires that I "alter table" and "drop constraint" All constraints drop properly, except one. The last one will churn away forever in query analyzer and never drop. I am unable to make the necessary changes until this completes. I am guessing that there is a data issue that is keeping the constraint from being dropped. Any ideas on how to proceed? Thanks!
View 2 RepliesHello, 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!

How to recreate CONSTRAINT column_c_fk without droping and reacreating column column_c or add new CONSTRAINT on column column_c ?
Thanks a lot .
Hello !
I am using Microsoft SQL Server 2000
I am trying to drop a column that has a constraint, executing the script inside a transaction:
BEGIN TRANSACTION
ALTER TABLE MOPTeste DROP CONSTRAINT FK_IDMOPPais
ALTER TABLE MOPTeste DROP COLUMN IDMOPPais
COMMIT
If i dont commit the drop constraint, it wont let me drop the column
Solutions?
I have to drop foreign key constraint from one table. How can I do that? Is it possible?
Also,
Is it possible to add a foreign key constraint on the table once it has a data?
I am very new to sql and I have got this doubt.
CREATE TABLE employee
{ EMP-ID VARCHAR UNIQUE,
DESIG VARCHAR UNIQUE,
SALARY INT };
Probably this is worst table ever created :).Now How to drop UNIQUE constraint on only column lets DESIG.
if i write
ALTER TABLE employee
DROP CONSTRAINT myuniqueconstraint;
will drop constraints on both columns which I dont want.
Any query that remove UNIQUE CONSTRAINT only on DESIGN column.
and one more clarification,
ALTER TABLE employee
MODIFY SALARY INT NOT NULL;
ALTER TABLE employee
ALTER COLUMN SALARY INT NOT NULL;
which of the above two is right query to add NOT NULL constraint to the above employee TABLE?

I need to run the alter table to drop a default. However, the default name is kind of 'dynamic' from around 1000 databases, thus I need to run the following sql to get the name to a variable. Now, it looks the alter table statement does not like to drop a vaiable, is there a solution about it?
declare @radius_default varchar(40)
select @radius_default = (select sobj.name from sysobjects sobj
inner join syscolumns scolumn
on sobj.ID = scolumn.cdefault
where scolumn.name = 'radius' and sobj.name like '%LandMarks%')
print 'Need To Drop @radius_default: ' + @radius_default

alter table LandMarks drop constraint @radius_default

Hello,
I have two tables Person & Location where Location has a primary key LocationId and Person has a foreign key LocationId.
Sometime ago I used the Database Diagrams visual tool of SQL Server Management Studio Express to create the foreign key relationship between the two tables - i.e. "visually" (drawing a line between the PK & FK LocationId elements of both tables).
Time has passed and I recently noticed that, upon retrieving my saved diagram, the foreign key relationship had "fallen off" (i.e. the many-to-one line was no longer showing in the diagram).
After recreating the relationship (redrawing the line) I find that I get an error message when I try to save the diagram:
Post-Save Notifications
[!] Errors were encountered during the save process. Some database objects were not saved.
'Location' table saved successfully
'Person' table
- Unable to create relationship 'FK_Person_Location'.
The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "FK_Person_Location". The conflict occurred in database "mydb", table "dbo.Location", column 'LocationId'.
When I go back to the object explorer and view the dependencies for the two tables, there is no dependency (between these two tables) revealed. When I try to create the foreign key constraint manually (T-SQL) it again says can't add the constraint. It comes up with an error as follows:
ALTER TABLE Person
ADD FOREIGN KEY (LocationId) REFERENCES Location (LocationId)
Msg 547, Level 16, State 0, Line 2
The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "FK__Person__LocationId__793DFFAF". The conflict occurred in database "mydb", table "dbo.Location", column 'LocationId'.
(Note: Each time I do this, the 8 hexadecimal character suffix changes.)
When I try to drop the foreign key:
alter table Person
drop constraint FK__Person__LocationId
it comes back with the error:
Msg 3728, Level 16, State 1, Line 2
'FK__Person__LocationId' is not a constraint.
Msg 3727, Level 16, State 0, Line 2
Could not drop constraint. See previous errors.
So it seems that there's some kind of goof up here. Can anybody shed light on this / tell me how to fix it?
I have an activex script which executes a query that never finishes. If I recompile the query in Management Studio before I run this step, then the step will *usually* work fine. This is the last step in a very long update process so the data has changed a great deal when this step executes.
The query always works fine in Management studio btw.
I am using BI studio to run the package.
I have tried placing a step before this that marks the query for recompilation but that doesnt seem to work. Any ideas how to resolve this?
I have a package which truncates files, fills them with data andshould send a mail with the files as attachment when it finishesrunning. In between, when the task is still running mail is sent withempty files. When I take a look at the directory (at the end of thetask), where the files are created I find out that the files are notempty.(e.g. in task: doA->doB->doC->SendMail. But instead of waiting tilldoB->doC finishes, it does the following: doA->SendMail ... may bebecause doB takes long.)Can I indicate anywhere that it should delay the mail until at the endof the task?Thanks in advance.Harp
View 1 Replies View RelatedHello everyone
Here is the situation I'm trying to set-up a package to ftp some files down if that part fails email me but if successful rename the 2 files to something else.
so what I set-up was a FTP tasks with the remote path set as a expresion since I needed to Download todays files.
no problem there have that part working.
so then I set a notifaction event with failure constraint to email me. pretty easy so far.
then I set 2 tasks to rename the 2 files downloaded I'm sure I could do this part with a loop but what seperate tasks so I knew if any failed or could set-up notifaction tasks if I wanted. in the 2 rename tasks I set the sourcepath to an expression so it would know to read todays files and they could change from day to day.
then the destination part is hard coded for now to a file name.
now here is were the issue comes in I go to save it and it says the files don't exist from the rename piece. well of course not they haven't been FTPed yet.
so I tried delayevaluation on both the file system tasks but a no go still errors.
What I need it to do is basically say wait till the ftp is run these files won't be there. any help in the right direction would be appreciated.
thank in advance

I am cleaning up a large database table that has Date keys instead of real DateTimes. To do this, I am running the following query...
UPDATE MQIC.DBO.OBSERVATION_F
SET MQIC.DBO.OBSERVATION_F.OBS_DATE = MQIC.DBO.DATE_D.ACTUAL_DATE
FROM MQIC.DBO.OBSERVATION_F INNER JOIN MQIC.DBO.DATE_D
ON MQIC.DBO.OBSERVATION_F.DATE_KEY = MQIC.DBO.DATE_D.DATE_KEY
where Actual_Date is what is being stored, and the Date_Key is to be dropped.
The particulars are this -
Date_D table - 92,000 rows - 40 MB
Observation_F - 2,000,000 rows - 3.2 GB
This is being run on a remotedly hosted rack server with an AMD processor, 1 GB RAM, 60 GB harddisk space, 20 GB used.
SQL-Server 2005 Express - SP1
If I do the same query as a SELECT Statement,
UPDATE MQIC.DBO.OBSERVATION_F
SELECT MQIC.DBO.OBSERVATION_F.DATE_KEY, MQIC.DBO.DATE_D.ACTUAL_DATE
FROM MQIC.DBO.OBSERVATION_F INNER JOIN MQIC.DBO.DATE_D
ON MQIC.DBO.OBSERVATION_F.DATE_KEY = MQIC.DBO.DATE_D.DATE_KEY
it runs to completion in about 15 min - during the entire time there is extensive used of CPU from Task Manager.
If I do the above statement, it seems to use lots of resources (50% +) for about 5 min, then falls to 5%. It just seems to sit there, for an hour + at which time I've killed the query.
This is actually the second time I tried this. The first time was on a different machine, with the P4, 3GB RAM, plenty of disk space, and using SQL-Server 2005 Standard - SP1. Exactly the same decrease in resources happened, and even though it ran several hours, no results.
Any thoughts here - not waiting long enough, memory leaks, etc.?
Thanks!
Hi,
I have a query which used to run fine on a rubbish SQL 2000 box in about a minute, but with SQL 2005 (SP2) it never finishes, even when left overnight. No errors in the logs or anything. It is the same database which was backed up from SQL 2000 and restored into 2005. Does anybody have any ideas?

DML T-SQL works fine. But When I try to run SELECT query with joins that involves large tables (1.5 mil rows in each) in 2 databases, it instantly goes into "runnable" status and never finishes. It never finishes even when I have top 1 clause included. When I run insert or update that involves same tables, it works just fine.
Server facts:
W2003
SS 2K5 SP2
Db Comp level 90 (for all db)
MAXODP = 1 (8 processor box)
Recently moved databases from server that had SS 2000.
When this query was running on box with SS 2000, it took about a minute to finish, but it completed.
I already tried: changing MAXODP settings, using OPTION (maxdop 1) etc.
Anything else I can try.
My SSRS report never finishes running for some reason.
If I run the same SP with the same parameters from SSMS it runs in 0.5 sec (returns 8-10 rows).
When running from report manager, I see extremely high CPU Time and Disk IO values, no blocking, no waiting at 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.
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?
I have a merge join (full outer join) task in a data flow. The left input comes from a flat file source and then a script transformation which does some custom grouping. The right input comes from an oledb source. The script transformation output is asynchronous (SynchronousInputID=0). The left input has many more rows (200,000+) than the right input (2,500). I run it from VS 2005 by right-click/execute on the data flow task. The merge join remains yellow and the task never finishes. I do see a row count above the flat file destination that reaches a certain number and seems to get stuck there. When I test with a smaller file on the left it works OK. Any suggestions?

Hello
I have interesting situation with one of my update statement.
Update takes 2 min to run and usually updates 20000 rows.
However lately update executes for longest time - 10 hours.
After I reindex table the updates run fine again
Please advice what can cause this
I do not think reindexing table before every update is good idea
We are running SQL 2000 SP4, Windows 2003 Server

Hi folks.
Here i have small problem in transactions.I don't know how it is happaning.
Up to my knowldge if you start a transaction in side the transaction if you have DML statements
Those statements only will be effected by rollback or commit but in MS SQL SERVER 7.0 and 6.5
It is rolling back all the commands including DDL witch it shouldn't please let me know on that
If any one can help this please tell me ...........Please............
For Example
begin transaction t1
create table t1
drop table t2
then execute bellow statements
select * from t1
this query gives you table with out data
select * from t2
you will recieve an error that there is no object
but if you rollback
T1 willn't be there in the database
droped table t2 will come back please explain how it can happand.....................

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

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
