TSQL - Using ALTER TABLE - ALTER COLUMN To Modify Column Type / Set Identity Column

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,
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;

Alter An Identity Column

Feb 5, 2003

I'm attempting to remove the IDENTITY property from a column using the ALTER command but can't seem to find the right syntax. I've tried every conceivable combination I can think of. I can add the property to a column that doesn't have it.

It's easy to do in Enterprise Mgr., but I want to script the change.

I really don't want to drop the table and rebuild if I don't have to.

Alter Column To Add IDENTITY

May 8, 2008

Hello All,
There is a table A in SQL. One of the column of A was IDENTITY before and was getting referenced in other table B.

During migration to SQL 2005, I removed the IDENTITY constraint and imported all the data from 2000 to 2005. Now I have to deploy the IDENTITY back to the column. I am getting an error while executing the code:

ALTER TABLE TableA
ALTER COLUMN ColumnA
ADD CONSTRAINT IDENTITY(445,1)


Can anyone tell me where I am going wrong? Or if there is any other way to do it. There are 50+ tables I need to do the same.

Thanks,
-S

Alter Column Drop Identity

Apr 18, 2008

Is there any way to remove the IDENTITY property of a column? I originally used it, but it caused so many headaches with ADO.NET that I've decided to just increment the darn things manually. So I want to turn it into just a normal integer column.

If there's no direct way, can someone suggest a quick way to create a new column, copy all the old values into the new column, change the primary key to the new column, and drop the old column?

Thanks.

Help With ALTER TABLE SWITCH (IDENTITY COLUMNS)

Feb 13, 2008

I am having problem when performing the alter table switch. Both tables are identical and have pk.

ALTER TABLE SWITCH statement failed. There is no identical index in source table 'LocalDeltanet.dbo.testresults' for the index 'PKIDX_testSummary' in target table 'LocalDeltanet.dbo.testresults_part' .

I have performed the function on other tables successfully, but this is the first that has an identity column involved. Is there anything special that needs to be done?

Alter Column Results In Incorrect Syntax Near 'column'

Oct 29, 2001

I ran this query against the pubs database and it runs successfully

ALTER TABLE publishers ALTER COLUMN state CHAR(25)

I change the table & field names for my db as follows:
ALTER TABLE customquery ALTER COLUMN toclause CHAR(25)

and run against my database and I get the following error - Incorrect syntax near 'COLUMN'.

My column name is correct - I don't know why it would run fine against pubs, but not my db. I do not have quoted identifiers turned on. I have tried using [] around my column name [toclause], but that didn't change anything. Any help would be appreciated.
Thanks.

I have a table with a column defined thus: LOCNumber Varchar(100) in atable called Bookdata.If I execute ALTER TABLE BookData ALTER COLUMN LOCNumber varchar(100)on the table, does any work get done on the table and column?Or does SqlServer know that the column is already varchar(100) andnothingneeds to be done?If it does do some work, how do you tell it not to run this as it isalready a varchar(100) column. Right now my program just blindly doesthis ALTER TABLEstatement regardless of any conditions. Is this a potential problem?Thanks for any help.

How To Use Identity On Non-identity Column (with Concurrence)

Aug 1, 2014

I'm working with a third-party database (SQL Server 2005) and the problem here is the following:

- There are a bunch of ETL processes that needs to insert rows on a table (let's call this table T) and at the same time, an ERP (owner of T) is up and running (reading, updating and inserting on T).

- The PK of T is an Integer.

Today all ETL processes uses (select max(ID) + 1 from T) to insert new rows, so just picture the scenario. It is a mess! Everyday they get duplicate key error when 2 or more concurrent processes are trying to insert a row (with the max) at the same time.

Considering that I can't change the PK, what is the best approach to solve this problem?

To sum up:

* I need to have processes in parallel inserting on T

* I can't change anything on T

* The PK is NOT an Identity

Alter Table Add Column - How Do You Add A Column After Say The Second Column

Jul 11, 2007



When you use "Alter Table add Column", it adds the column to the end of the list of fields.



How do you insert the new column to position number 2 for instance given that you may have more than 2 columns?



Create table T1 ( a varchar(20), b varchar(20), c varchar(20))



Alter table add column x varchar(20)

so that the resulting table is

T1 a varchar(20), x varchar(20), b varchar(20), c varchar(20)



Can this be done programmatically?

How To Refer A Column When The Referencing Column Is An Identity Column

Oct 16, 2006

Hi all,

The requirement is to have a table say 'child_table', with an Identity column to refer another column from a table say 'Parent_table'..

i cannot implement this constraint, it throws the error when i execute the below Alter query,

ALTER TABLE child_table ADD CONSTRAINT fk_1_ct FOREIGN KEY (child_id)
REFERENCES parent_table (parent_id) ON DELETE CASCADE

the error thrown is :
Failed to execute alter table query: 'ALTER TABLE child_table ADD CONSTRAINT

CASCADE '. Message: java.sql.SQLException: Cascading foreign key 'fk_1_ct' cannot be
created where the referencing column 'child_table.child_id' is an identity column.

In SQL Server 2005 (Mgmt Studio): according to BOL, the syntax to set a default value for an existing column is:

ALTER TABLE MyCustomers ALTER COLUMN CompanyName SET DEFAULT 'A. Datum Corporation'

However, when I Check:

alter table CommissionPayment alter column Amount Set Default 0

I get the error message:

"Incorrect syntax near the keyword 'Set'."

No other combinations of this syntax work.
