How to remove the constraints on a table in sql server 2000? I need to drop the column, so i need to drop the constraint before that.
Alter Table Table_Name NO CHECK constraints ALL.
Once I execute the above one, it says, "Successfully Executed" but when I try to drop it doesnt allow me and gives me the following error:
Server: Msg 5074, Level 16, State 1, Line 1
The object 'DF_Users_Created_by' is dependent on column 'CREATED_BY'.
Server: Msg 4922, Level 16, State 1, Line 1
ALTER TABLE DROP COLUMN CREATED_BY failed because one or more objects access this column.
Assuming that I have created relationships (PKs and FKs) on my tables already, does the following statement permanently remove a Foreign Key constraint, or does it mearly disable it?ALTER TABLE myTable NOCHECK CONSTRAINT FK_myForeignKeyGO Also, I can't seem to find out how to temporarily remove the Identity qualifier of a field, and then reset it back as Identity later. Any help?Finally, will a failure of ALTER TABLE affect the @@ERROR variable? Can I check @@ERROR after each ALTER TABLE table statement to see if @@ERROR <> 0?The reason for both of these issues is that I am redesigning an unnormalized database, and I need to write a large script to drop all constraints on all tables, transform the data as normalized into the new table structure, and then re-enable constraints, Identity fields, etc. Thanks.
I have some C# code written a little while that imports data nightly into a database. Most of the data is typically deleted from the tables and imported again. There are some tables where data is never deleted and references other tables. Because there are constraints between these tables, the code processes the import in the following sequence.
get constraints from database->drop constraints->delete data->apply constaints->import data
I was curious how I can accomplish similiar results in SSIS. I know I can execute a process task to manage the constraints, but I was wondering if there is any other way.
We've got a product which uses merge replication with anonymous pullsubscriptions. At most custome sites it's running on SQL Server 2000, a few with SQL 2005, which is running wich replication compatibility level 80 due to . As it happens, db schema changes. So I have to drop a column with a default constraint. First the constraint, then the column. This works excellently on the publisher - but not on the subscriber

Hi, I want to drop a column from a table with default constraint. It is giving me error.. ------------------ Server: Msg 5074, Level 16, State 1, Line 1 The object 'DF__ACTIVITY___ROLLU__108B795B' is dependent on column 'ROLLUP_BGT_COST_FIXED'. Server: Msg 4922, Level 16, State 1, Line 1 ALTER TABLE DROP COLUMN ROLLUP_BGT_COST_FIXED failed because one or more objects access this column. -------------------------
Here is the drop statement ----------- DROP STATISTICS ACTIVITY_BASELINE.ROLLUP_BGT_COST_FIXED ALTER TABLE ACTIVITY_BASELINE DROP COLUMN ROLLUP_BGT_COST_FIXED; ------------------------
I just looked at a coworker's stored procedure and this person isdropping 4 Foreign key constraints and then re-adding them afterprocessing the required logic (updating rows in the 4 tables inquestion).Is there *ANY* good reason to do this? What are the performanceimplications of doing this - negative or otherwise?I was furious when I found this because every once in a while I wouldnotice that the constraints would be in flux....some days they werethere, othere days there were not. I mean, this is a good enough reasonto NOT do this, but I need some additional feedback. Maybe there *is* agood reason, and that the logic just needs tweaking.Thanks.
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.
Is there a way we can prevent a object owner from dropping his tables. Example:
There is a user called 'tom' who is given create table permissions, 'tom' creates the table completes his dev and then the table is moved into production where 'tom' is still the owner. However, in production, 'tom' does not have the create table privs. Because 'tom' is the owner of the table, he is still able to drop the table in production. This is what I am trying to avoid. I would like to retain 'tom' as the owner and want to take away his create/drop privs.
Does anyone have any generic scripts that Drop all the statistics that SQL auto generates?? I have hundreds of '_WA_....' indicies that are auto created by SS7 and I just want to get rid of ALL of them. Thanks!
I need to drop a database but cannot because there are 2 open connections that I cannot drop via EM. Is there a way to do this without starting and stopping??
After I drop the database, I backed up the master database, I recreate the database with new name. When I tried to do the import on the command level, It gives me the error: Attempt to locate entry in the sysdatabases for database 'db1' by name, failed -- no entry found in that name.
Hi I am using SQL server 7 database and ASP as front end. I run an application where a text file is loaded into database.

I have a database that is giving me a bad Index error. When I go to drop the necessary Index it is telling me that it either does not exist or cannot be dropped. However when I try to build that index, it tells me one already exists.
Is there any way to drop all of the indexes or at the very least see what the indexes are? This particular database is using 2005 Express.
I think the answer to this question will be something like 'you'll have to re-initialize the subscribers', but I need to ask anyway...
I created a publication where my foreign key constraint we NOT created with NOT FOR REPLICATION. My publication is configured to replicate DDL changes. Is there any way I can drop and re-create the constraint in the publisher and get replication to push the change to the subscribers?
I have trouble dropping a job that was a maintence plan.
I get the following error. Is there a way around this?
TITLE: Microsoft SQL Server Management Studio ------------------------------
Drop failed for Job 'Maintenne Plan'. (Microsoft.SqlServer.Smo)
An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)
------------------------------
The DELETE statement conflicted with the REFERENCE constraint "FK_subplan_job_id". The conflict occurred in database "msdb", table "dbo.sysmaintplan_subplans", column 'job_id'. The statement has been terminated. (Microsoft SQL Server, Error: 547)
I am trying to run a dymanic DROP DATABASE <dbname> command in a stored procedure called from ASP.NET. I typically connect from the .net using a SQL builtin account. I am getting this error:
System.Data.SqlClient.SqlException: Cannot drop the database 'db_testco', because it does not exist or you do not have permission.
The database is there for sure asI can browse it via the Studio manager. What permission do I need to set for my .net login to allow it to drop ? I tried adding the Delete permission to the database and still no go...
I have a table with multiple column and has millions of rows in it(say about 50 millions ) and its in production. What is the best way of dropping the a column from the table without impacting the systems performance. Remeber this table will be used some application to get some data out of it.
I think I am doing something wrong. I am trying to make the trigger fire when I want to drop the same trigger. For example I have the following trigger defined:
USE AdventureWorks2000
GO
CREATE TRIGGER Incheckstock
ON DATABASE
FOR DROP_TRIGGER
AS
PRINT 'You must disable Trigger "Incheckstock" to drop Trigger!'
ROLLBACK
GO
SET ANSI_NULLS OFF
GO
SET QUOTED_IDENTIFIER OFF
GO
ENABLE TRIGGER Incheckstock ON DATABASE
DROP TRIGGER Incheckstock
ON DATABASE
I created the trigger Incheckstock and i want to see if the same trigger fires itself if when i am trying to drop the trigger with the same name (kind of recursive one). Is this possible in SQL 2005?. If I asked a dumb question, please correct me.
I'm having a problem updating my Client profile table. I intially put the data in with the "INSERT" SQL command that part works great. but when I retrive the data to edit the profile it returns the correct details and phone numbers. The problem is when I use the "UPDATE" SQL command it saves all the data correctly except for the mobile phone number which it drops off the last number all the time. Field sizes etc are okay. Any help appreaciated
I guess nobodys heard of this? I'm using DTS to transform data to Excel spreadsheet. I have a DROP TABLE `data$` then a CREATE TABLE `data$` the old data is cleared but the new data is appended to the blank rows of the old data. So if I had 5 rows before now I have 10. And the new data has 5 blank rows before it.
I've tried deleting the excel file & replacing it with a new one. I've used the wizard thinking it was me but no good, it still happens.
I am using Access 2000 to link tables from SQL Server. The tables are linked using ODBC DSN`s. I am running a query to return some rows to Access, but once I have returned the rows, I want to drop the linked table connection to SQL Server, because it is locking a table on the server. I think I need to write a bit of VBA code, but I don`t know where to start. Any ideas would be greatly appreciated. Thanks.
SQL 7 created by default a clustered index on my primary key field. I would like to drop this index and recreate it on another field, but it is not allowing me. Error message states: "An explicit DROP INDEX is not allowed... It is being used for PRIMARY KEY CONSTRAINT enforcement." Can anybody advise how I can solve this? TIA
Hi Has anyone heard of MS SQL Server 7 dropping indexes? I had created an index on a table. The next day the index had disappeared. Has anyone expirienced such a problem?
