Sep 7, 2007

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,

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),

How To Alter Column Length Of The Master Table Along With The Slave Table?

Aug 13, 2006

In SQL Server 2005,here are two tables, created by the following SQL Statements:

CREATE TABLE student(
ID CHAR(6) PRIMARY KEY,
NAME VARCHAR(10),
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)

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)?

Thanks!

ALTER TABLE SWITCH PARTITION On A Replicated Table

Apr 10, 2007

A 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?

Alter Table

Oct 17, 2001

Hi,
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.

Steve

Alter Table

Jan 30, 2004

Hi 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!
Sergio

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

begin
alter table @name add ins_id int
end

fetch next from c into @name
end

Alter A SQL Table

Aug 18, 2006

I used the MS Access 2000 Upsize wizard to create a Client/serverapplication. After the wizard ran, the original table names had becomethe linked tables and then there were duplicates of the the tablesnamed xxx_local.I realized later that I needed to add some fields to a table andcouldn't do that in Access (couldn't edit the linked tables). So I usedthe Query Analyzer and created a script to add the fields to my table.It looked fine in Query Analyzer, but back in Access the fields wereadded to xxx_local and not xxx, the linked table. My forms and reportsare built on xxx, not xxx_local.How do I do this correctly?Jane

Alter Table- ID

Jan 28, 2008

I 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.

The statement has been terminated.

Alter Table

Mar 18, 2008

hi,

i have table having just two columns. One of columns is defines as nchar(5).

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
Lubos

SQL Alter Table Statement With Bit's

Oct 13, 2000

Hi List,

I am trying to add a column with Alter Table, like this:

ALTER TABLE myTable ADD
newColumn bit DEFAULT 0 NOT NULL

This works fine with SQL-server 7, but I get this error in 6.5:

'ALTER TABLE only allows columns to be added which can contain nulls. Column 'newColumn' cannot be added to table 'myTable' because it does not allow nulls.'

I also found this in the help files:

'Columns added to a table must be defined as NULL. When a column is added, the initial value for the column will be set to NULL. This restriction forces the ALTER TABLE statement to fail if the bit or timestamp datatypes are used.'

My question, is there any other way to do this on 6.5 ?
