Can IDENTITY Colum Be ALTERED?

Jun 7, 2001

Hi All,

Just want to know if a column with IDENTITY can be altered. If yes, how?
I have a table with colum defined like this:

CREATE TABLE [dbo].[Test] (
[TestID] [int] IDENTITY (1, 1) NOT NULL ,
.......

Through ALTER TABLE script (I don't want to do it through Enterprise Manager) I want it to be like this:

CREATE TABLE [dbo].[Test] (
[TestID] [int] IDENTITY (1, 1) NOT FOR REPLICATION NOT NULL ,
.......

I want the constrain "NOT FOR REPLICATION" done through ALTER TABLE script. Is that possible?

Please let me know with the syntax.

Thanks
Sri

Altered Table-changed Column From Text To Varchar And Now Having Issues With Alter Switch

Feb 14, 2008

Working on partitioning a few large tables. One of the tables included a text column and the €śTEXTIMAGE_ON [PRIMARY]€? clause which would prevent the partitioning of this table. After some research we found that the data was legacy and no longer used. We updated the column on the affected rows to NULLS and altered the column to a VARCHAR(20)
When I attempted to run the ALTER TABLE SWITCH I encountered the error
Msg 4947, Level 16, State 1, Line 1
ALTER TABLE SWITCH statement failed. There is no identical index in source table 'LocalDeltanet.dbo.testresultsjoe' for the index 'PKIDX_testSummary' in target table 'LocalDeltanet.dbo.testresults_part'.
After a lot of grief and testing I determined that the message was bogus and the real issue is that the 'sys.tables' still has €ślob_data_space_id€? with a value of 1 for this table.
I created a copy of the table with the text column altered to varchar and one with just the varchar to begin with. After copying data from the original table, I tried to run the alter switch. It failed once again for the text column altered to varchar table, but it worked for the varchar from the start.

Since it appears that this value is causing my issues, is there anyway to update the table in place. I know I can BCP the data out, but that would take too long and would defeat the advantage of using the alter switch method.

BOL States:

The allow updates option is still present in the sp_configure stored procedure, although its functionality is unavailable in Microsoft SQL Server 2005 (the setting has no effect). In SQL Server 2005, direct updates to the system tables are not supported. This means we cannot update the table manually.

Thanks

SQL Security :: Domain Migration Altered SA Or Domain Admin Access To DBs

Jun 19, 2015

we recently migrated from our in-house domain to the Enterprise domain. Everything went smooth except for the fact that I can no longer accept my dBs using my SA or my domain admin account. There is only 1 account I can get into the management studio with but it has no admin privileges, so I can't make any  password changes or add accounts. I don't have a test environment so kind of hesitant to experiment with our production system.

Oct 2, 2005

i wonder what is the best approach to use !!!i have creditLimit column in Customer Table the default value will be 500 and this limit to allow users to send sms from my website ..... every month they will be allowed to send 500 sms referring to the credit limit column.... now !!if the user sent today some sms and after few days sent another 20 and after one week he sent 150  SMS as a total so that means he has only 350 SMS as credit to use this month!!!so what is the best approach to implement this solution ? shall i have another field in the table called 'CreditUsed' and that will be updated each time the user will send SMS and this value will be compared with the credit limit ORi use the formula for the column to calculate the credit left and do the maths !!!what is the best approach as you think ???thnaks for reading this question !!

Colum Name - Alias

Aug 10, 2007

We are thinking of using general purpose column names in our application schema. We want to give the option to the end user to customize the filed names to fit their business . We want to build the functionality on the generic names so that it will work for multiple customes.

Example: We may want to have 10 Strings, 10 numbers and 5 booleans pre defined and reports running off of the table. The customer can name first number as pressure, second one for length and map their data to the table. Other customer can use the first number for temperature and the second one for width.

Is there a way to do it in SQL server w/o having a lookup table for column name aliasing?

Thanks

DTS Fails Coes It Refuses To Fill The Unique Id Colum

THe unique Id column is set to identity seed. Yet when transfering 1500 records it fails to stuff them all becuase it says there is a NULL in unique id column.
"Cannot insert the value NULL into column UID column does not allow"
 Yet in the transformation screen I am setting the UID column to <ignore> meaning I do not have that value in my source and I am wanting the destination table to do it's thing and incrememnt by 1 the identity seed.
 Is this common?
THe source and destination tables are in the same databes.

ADO.NET Returns Different Colum Value When Compared To View Results In SQL 2005 Management Studio

Feb 7, 2007

I have a complex view in my sql 2005 database.
The view returns a column that could be null (as the result of a left outer join).
The coulmn that is returned is an integer.
Everything works fine if I run the view from SQL 2005 Management Studio.
My column value is always null if I use ADO.NET's SqlAdapter to return a DataTable.
Has anybody seen this behaviour before?
Any help appreciated.

Last GASP On Insert Row In Table With Identity Field, And Get New Identity Back ?

Jul 9, 2006

While I have learned a lot from this thread I am still basically confused about the issues involved.

.I wanted to INSERT a record in a parent table, get the Identity back and use it in a child table. Seems simple.

To my knowledge, mine would be the only process running that would update these tables. I was told that there is no guarantee, because the OLEDB provider could write the second destination row before the first, that the proper parent-child relationship would be generated as expected. It was recommended that I create my own variable in memory to hold the Identity value and use that in my SSIS package.

1. A simple example SSIS .dts example illustrating the approach of using a variable for identity would be helpful.

2. Suppose I actually had two processes updating these tables, running at the same time. Then it seems the "variable" method will also have its problems. Is there a final solution other than locking the tables involved prior to updating them or doing something crazy like using a GUID for the primary key!

3. We have done the type of parent-child inserts I originally described from t-sql for years without any apparent problems. (Maybe we were just lucky.) Is the entire issue simply a t-sql one or does SSIS add a layer of complexity beyond t-sql that needs to be addressed?



TIA,

Insert Row In Table With Identity Field, And Get New Identity Back

Jun 30, 2006

I want to insert a new record into a table with an Identity field and return the new Identify field value back to the data stream (for later insertion as a foreign key in another table).

What is the most direct way to do this in SSIS?



TIA,

P.S. Or should I pass the identity value back in a variable and not make it part of the data stream?

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
