Alter Table Nocheck Constraint Still Some Dependencies
May 17, 2006
Hi.
I'm getting errors like this when I try to run an upgrade script I'm trying to
write/test:
altering labels to length 60
Server: Msg 5074, Level 16, State 4, Line 5
The object 'ALTPART_ANNOT_ANNOTID_FK' is dependent on column 'label'.
I used this to bracket my script:
sp_msforeachtable "ALTER TABLE ? NOCHECK CONSTRAINT all"
go
sp_msforeachtable "ALTER TABLE ? DISABLE TRIGGER all"
go
/* updates here */
sp_msforeachtable @command1="print '?'",
@command2="ALTER TABLE ? CHECK CONSTRAINT all"
go
sp_msforeachtable @command1="print '?'",
@command2="ALTER TABLE ? ENABLE TRIGGER all"
go
I guess the alter table nocheck constraint isn't disabling the fk's
completely?
Is there a way around this, or do I manually have to do the constraint
dropping/recreating?
I wanted to turn off 'Enforce Foreign Key Constrain' using SQL. However, it did not work on the SQL Server 2005 database.
For example, running following SQL in Management Studio, and the result showed that 'Enforce Foreign Key Constrain' property for the newly created constraint was still enabled.
ALTER TABLE [dbo].[Tags] WITH NOCHECK ADD CONSTRAINT [FK_Tags_ChannelID] FOREIGN KEY([ChannelID]) REFERENCES [dbo].[Channels] ([ID])
Does anybody know any way to get around with this problem. It is quite important for my software.
Is a NOCHECK constraint supported in CE 3.5? The keyword is listed in the 3.5 BOL but when attempting to ALTER TABLE using WITH NOCHECK the statement fails.
If it is not supported then is there a work around for it?
I have a stored procedure that adds constraints from a variable: ALTER procedure [dbo].[addMyConst](@txtAuto_ourlim money OUTPUT,@txtGen_ourlim money OUTPUT)ASEXECUTE('ALTER TABLE [dbo].[tbl1] ADD CONSTRAINT DF_auto_ourlim DEFAULT ' + @txtAuto_ourlim + ' FOR Auto_ourlim')EXECUTE('ALTER TABLE [dbo].[tbl1] ADD CONSTRAINT DF_Gen_ourlim DEFAULT ' + @txtGen_ourlim + ' FOR Gen_ourlim') This works fine unless one of the variables is null or empty. Then I get the error: "Incorrect syntax near the keyword 'FOR' Evidendly SQL Server Express sees "....DEFAULT + + FOR..." but I don't know. I've fiddled with this a long time and haven't a clue how to fix it. Any help would be appreciated. Thanks, Steve
I have a default constratint on DateColumn getdate()-1
I have used enterprise manager to update it to yesterday's date everyday.
I would like to have a SQL which can check for the date in the system or even a trigger which checks when the date changes the constraint is updated itself. If this is not possible I would like to have a stored procedure which I will schedule to run as a job everyday once.
So if today 6/12/2006, the default value in the Datecolumn should be 6/11/2006.
This gives me a error, i tried but could not fix the bug.
Alter Table TABLE_NAME Alter Constraint DF_DATECOLUMN Default getdate()-1
There is a table exists in a database name tbDatabaseProviders.
I want to alter this table to add a column DatabaseProvider Also I want to add a default constraint so if nothing than 1 should be added.
Remember, the table already exists so when I write the script query then I want to first check the constraint if it exists then I dont want to add the constrait otherwise I will add it.
I was having problem to first add a constraint with the constraint name so I could find the constraint before finding it if it already exists.
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
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.

I have a table in my SQL2000 server and there's a field in this table being created by an object - with a GREEN PLUS sign (look like an APPEND query in MsAccess). How can I locate and edit/modify that (append query-like) object within my SQL 2000 - Enterpise Manager? Here's some more details:
Table: Customer
Field1: CustomerID
Field2: CustomerRegion_ID (contains the ID above & RegionID below)
When I checked on the dependencies of the table "Customer" I saw 1 dependency and this dependency has 2 table depend on it back-to-back (Customer & Region).
I want to modify the "Field2" of the "Customer" table and I looked everywhere on my VB/stored-procedure codes but couldn't find what triggle the creation of the field. The only thing that I suspect that would be the append object with "GREEN PLUS" sign. Any help would be appreciated.
Is there any way to know as what are all the entities or objects which are dependent upon a given Table? I wanted to know if i update a particular table in a given database on a server, what are all the other tablesobjects which gets effected because of this updation, may be because of some update triggers defined on this tabl or through cascading updates etc. Any system stored procedure which can help me to know these dependencies.
Hi folks ... I am back with another quick question here. I was working on a table and on my absence it was dropped by one of my collegues. I restored it from the backup. The problem is it is not showing all the stored procedures and other tables under show dependencies as the original table was. Is it going to affect the way the stored proc. depenendant on it works..or everything will be fine? If the answer is yes...is there a way I can add the stored procedures or link it to the new table? Thanks for reading and any insight is more than welcome. Tanya
Hello,I have 3 tableTable 1 : list of "whatever" programTable 2: list of tasks for each programTable 3: list of user for each taskWhen I have a new program, I want to select existing task and copy them and assign them to my new program. But I also want to copy the list of user of each task.Is there a way to do that in sql?I do not really want to go through each single task, then copy it with the new program, then get the @@identity of the inserted task and then assign the same user to the newly inserted task.Thanks

i have written query to find out column names of a table in the database .
SELECT t.NAME AS TABLEName ,SCHEMA_NAME(schema_id)+'.'+c.name AS ColumnName FROM sys.tables t INNER JOIN sys.columns c ON c.object_id = t.object_id WHERE OBJECT_NAME(c.object_id) LIKE '%Message%'ORDER BY t.NAME
So far i got the Expected result but what ever column i am looking i want to find out the Dependency of column realted tables. by executing the above query i am getting table name and column name. How can i get the column related dependent tables.
Hi everybody. I need to find all the views that depend on a table in a different database, in order to refresh them once the table is altered.
In the BOL I found the following script that is very useful, but I can't use it if the view and the table are in different database. Where can I find the dependencies in this case?
Thank you very much.

I need to insert data into a table..please advise SQL Syntax on how to disable and enable constraints and triggers on the table before and after the inserts!
I've a table with primary key defined as non-clusterd, now without dropping it can I modify the existing index to clustered through tsql as I had to write some migration script and in that script I wanna do this.
Is there away to get the SQL FK constrain to trust old data when the FK is created with NoCheck.?
Some things to ponder
- Assume the table where the FK is created is too large and cant afford a significant down time, but still need the query optimizer to trust the data in the FK for optimal query plans.
- As pre-deploy script will validate the older data in the FK columns for consistency
Hi guys, If I have a temporary table called #CTE With the columns [Account] [Name] [RowID Table Level] [RowID Data Level] and I need to change the column type for the columns: [RowID Table Level] [RowID Data Level] to integer, and set the column [RowID Table Level] as Identity (index) starting from 1, incrementing 1 each time. What will be the right syntax using SQL SERVER 2000?
I am trying to solve the question in the link below: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2093921&SiteID=1
Thanks in advance, Aldo.
I have tried the code below, but getting syntax error...
ALTER TABLE #CTE ALTER COLUMN [RowID Table Level] INT IDENTITY(1,1), [RowID Data Level] INT;
I have also tried:
ALTER TABLE #CTE MODIFY [RowID Table Level] INT IDENTITY(1,1), [RowID Data Level] INT;
we have a table in our ERP database and we copy data from this table into another "stage" table on a nightly basis. is there a way to dynamically alter the schema of the stage table when the source table's structure is changed? in other words, if a new column is added to the source table, i would like to add the column to the stage table during the nightly refresh.
I have contract table which has built in foreign key constrains. How can I alter this table for delete/ update cascade without recreating the table so whenever studentId/ contactId is modified, the change is effected to the contract table.
Thanks
************************************************** ****** Contract table DDL is
create table contract( contractNum int identity(1,1) primary key, contractDate smalldatetime not null, tuition money not null, studentId char(4) not null foreign key references student (studentId), contactId int not null foreign key references contact (contactId) );
For the length of Column ID is not enough, So I want to alter its length.The alter statement is:
ALTER TABLE student ALTER COLUMN ID CHAR(20)
For the table student is referenced by table score, the alter statement can not alter the column of the table student, and the SQL Server DBMS give the errors.
But, I can manually alter the length of the column ID in SQL SERVER Management Studio. How to alter column length of the master table(student) along with the slave table(score)?
