How To Alter Column Length Of The Master Table Along With The Slave Table?
Aug 13, 2006In SQL Server 2005,here are two tables, created by the following SQL Statements:
CREATE TABLE student(

AGE INT
);
CREATE TABLE score(
ID CHAR(6) PRIMARY KEY,
SCORE INT,
FOREIGN KEY(ID) REFERENCES student(ID)

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)

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)?

Apr 10, 2007A customer wants to implement table partitioning on a replicated table.
They want to hold 13 months of data in the table and roll off the earliest/oldest month to an identical archive table. The table has a date field and partitioning by month makes sense all around.
So SWITCH PARTITION is the obvious solution to this, except for the fact that the table is replicated (transactional w/no subscriber updates).
What are his architectural or practical solutions to using table partitioning and replication?

Oct 17, 2001Hi,
is it possible to override the system when adjusting
columns. i.e. a system override setting.
For instance if I've got a column that is indexed and I
want to adjust it from varchar(50) to varchar(51) it lets
me. But if I then try and adjust the column to varchar
(49) I get the error below:
Server: Msg 5074, Level 16, State 8, Line 1
The index 'LastName' is dependent on column 'lastname'.
Server: Msg 4922, Level 16, State 1, Line 1
ALTER TABLE ALTER COLUMN lastname failed because one or
more objects access this column.
I asked this question on another Forum and was told I had to drop the index first. Just thought I'd ask for a second opinion.
Thanks for the help.

Jan 30, 2004Hi to all!
I have a silly problem, but I'm not able to solve it!
I know how to add a field in a table via Enterprise manager and I know also via ALTER TABLE command.
...But the problem is: I want to add a field NOT in the last position, but on the middle (for istance)
So, this is possible via Enterprise Manager but with the ALTER TABLE command? How can I add a field without put it in the last position?
...Thanks a lot!

p.s.: Sorry for my poor english..I hope you understand my question!

deallocate c

Jan 28, 2008I am trying to insert some new rows in the table tbl_3, but the problem is that I don't know how to go along with the ID column. I want to insert new rows so that it gets appended at the end and new ID is automatically generated.
Looks like this had to be done while creating the table. The original table has the id assigned as 'Identity', but I have imported this table to my database and now it does not show that property in the ID column.
The Insert code that I am using is as follows and the tbl_3 has same no. of columns except it also has id.
Can I alter table without touching the previous IDs? The ids start at 28118 and ends at 28300.
Code Snippet
INSERT INTO [dbo].[tbl_3]
(3_name
,3_sort
,3_active
,3_display
,3_date)
select _MANUFACTURERNAME , 1, 1, 'True',
GETDATE()
from dbo._MANUFACTURERS where upper(_MANUFACTURERNAME) not in (
select Upper(3_name) from dbo.tbl_3 join
dbo._MANUFACTURERS on Upper(3_name) = Upper(_MANUFACTURERNAME))
And the error it is returning to me is
Msg 515, Level 16, State 2, Line 2
Cannot insert the value NULL into column '3_id', table '.dbo.tbl_3'; column does not allow nulls. INSERT fails.

Want to alter table like
ALTER TABLE [dbo].[TestTable] ALTER COLUMN [Something] [nchar] (2)
COLLATE Latin1_General_CI_AS NOT NULL
GO
?
This script runs without problem till i have no data in table. When i add one row, this script fails with
Msg 8152, Level 16, State 13, Line 1
String or binary data would be truncated.
The statement has been terminated.
When i change the table in design mode, it says that data will be truncated and do the change (with truncating).
So is there any possibility (a switch or whatever) to update this table by script with letting engine truncate data?
Thanks for any response

I have 3 tables: Articles, ArticlesTags and Tags.
ArticleTags relate Articles and Tags records.
When I try to delete a record in Tags I get the following error:
The DELETE statement conflicted with the REFERENCE constraint
"FK_ArticlesTags_Tags". The conflict occurred in database "MyDB", table "dbo.ArticlesTags", column 'TagID'.
The statement has been terminated.
What am I doing wrong?
Here is how I am creating my tables:
create table dbo.Articles

)
create table dbo.ArticlesTags
(
ArticleID uniqueidentifier not null,
