Adding Identity Column To BIG Table
Jul 20, 2005
I've got a table with 36+ million rows. I've been asked to modify the
table and add in an identity column. The code I used caused SQL to
lock up and it maxed out the log files. :)
The code I used is:
Begin Transaction
Alter Table ODS_DAILY_SALES_POS
ADD ODS_DAILY_SALES_POS_ID BigInt NOT NULL IDENTITY (1,1)
Commit
Is there a way to break up the code? Maybe only do a few million
records at a time? Or is there a way to do this without locking
anything up?
Thanks,
Jennifer

I removed all constraints in order to load a bunch of data into a table, now I'm wondering if I can add an identity column to this table which does contain data or if I have to create a new table with the identity column and insert the data into that.
thx

Hi,
I am having problem in bulk update of a sql server table haning identity column from a datatable( has no identity column) using sqlbulkcopy. I tried several approaches, but it does not show any error nor is the table getting updated. But the identity value seems to getting increased every time.
thanks.

Hi,In my stored procedure I'm doing a SELECT onINFORMATION_SCHEMA.TABLE_CONSTRAINTS. However there is no unique id onthis table, so I was wondering if it was possible to add it dynamicallyin my SELECT, so that I would assign a unique id to each recordreturned by my SELECT?Thanks for your support.

I need to add a column that has the datatype of integer with a seed and identity increment to a table that already exists and has data in it - and can't all NULLs. I have heard that this not possible if the table already exists.
I have downloaded the demo's of SQL Programmer and a couple of Embarcadero programs to see if that would help, but have had no succes to date.
Thanks for any help,
Alan

After SQL server service restart, a column which is set to auto increment jumped 1000. To fix the issue, I had to add T272 trace flag to SQL startup parameters. However, I did not see the column being reseeded after the service restart, it is still showing the 1000 jump. Am I doing something wrong?
Below the log showing the flag being added to the error log:

I have a table of raw data where each column can be null. The thought was to create an identity key (1,1) and set as primary for each row. (name/ address / zip/country/joindate/spending) with surrogate key: "pkid".However other queries will not use this primary key. So for instance they may count the # of folks at a zip, select all names, addresses etc. The queries may order by join date, or select all the people that joined on a specific date.No other code would logically use the primary key (surrogate primary id key), therefore would it still have any performance benefits? at this time the table would have no clustured or nonclustured indexes or keys. I'm curious if there are millions of records.

I simply need the ability using SQL to add columns in an existing table before (or after) columns that already exist.
The MS SQL implementation of ALTER TABLE doesn't seem to provide the before or after placement criteria I require. How is this done in MS SQL using SQL or is there a stored procedure I can use?
Thanks.

If on the source I have a new column, the script generated by SqlPackage.exe recreates the table on the background with moving the data into a temp storage. If the table is big, such approach can cause issues.
Example of the script is below: in the source project I added columns [MyColumn_LINE_1] and [MyColumn_LINE_5].
Is there any way I can make it generating an alter statement instead?
BEGIN TRANSACTION;
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
SET XACT_ABORT ON;
CREATE TABLE [dbo].[tmp_ms_xx_MyTable] (
[MyColumn_TYPE_CODE] CHAR (3) NOT NULL,
[Code] ....
The same script is generated regardless the table having data or not, having a clustered or nonclustered PK.

Hi guys,
If I have a temporary table called #CTE
With the columns
[Account]

[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:

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 a table size 2078mb, number of row +530,900. Is it normal for sql to lock users out of the db when I add a column to the end of the table? I'm running SQL 7.0. The table has 4 col regular indexes. No primary keys. It locked the user out for about 10 min. I thought with SQL 7.0 this problem went away?

Can I add a column to a database table without dropping and recreating the table?
The problem is that everytime a user creates an action that requires a new table - at the moment I drop the table and recreate the table with the new column.
This requires lots of resources as I have to populate the table again.
Is there a design way I can go around this?

Hi,
I am trying to create a temp table with an identity column. Here is the code that I am using...
SELECT UserId, IDENTITY(int, 1, 1) AS colId
INTO #User
FROM MyUserTable
WHERE UserId = 1
I am getting an error though.
Server: Msg 8108, Level 16, State 1, Line 9
Cannot add identity column, using the SELECT INTO statement, to table
'#User', which already has column 'UserId' that inherits the identity
property.
Is there any way to work around this?

Having an identity column in target table, how do I use SQL 7 DTS ?
In Import wizard, I chose 'ignore' in source, checked Enable Indenity Insert - DTS failed with a msg like - a column cannot have NULL...
In DTS package, had Fast load and Enable Indenity checked - no luck !
What would be the standard procs for this since this sounds like a very common
senario.
Appreciate your help very much !

I'm sure this is a common problem but I can't find any relevant info on this site
I have a table that I would like to insert values into. I want to take the values from a secondary table using a select statement.
e.g. a simplified version...
TABLE1
(
Id INTEGER IDENTITY,
UserName VARCHAR(50),
Description VARCHAR(50)
)
TABLE 2
(
UserName VARCHAR(50),
Description VARCHAR(50)
)
Runing the insert statement
INSERT Table1 (UserName, Description)
SELECT *
FROM TABLE2
results in the error
erver: Msg 515, Level 16, State 2, Line 2
Cannot insert the value NULL into column 'Id', table 'CDS_Live.dbo.Table1'; column does not allow nulls. INSERT fails.
The statement has been terminated.
I was under the impression that an identity column would be automatically inserted by SQL server. Now I know I could write a piece of anonymous Transact SQL which declares a cursor by selecting all rows from table 2 and inserting rows into table 1 on a row by row basis, but is there any way I could do the Insert with a single INSERT statement?
thanks

Sorry I'm pretty new to SQL so I don't know if this is a simple question. I have a table, and I am trying to add a column to the table and populate this column using what would be called an 'IF' function in Excel.
Basically 'column A' has numbers in it. I want SQL to look at 'column A' and if the first 5 digits of the number in 'column A' are 00001, then put 'description A' into new column 'column B'. If the first 5 digits of the number in 'column A' are 00002, then put 'description B' into 'column A' etc.
Any ideas?

The column I'm adding needs to be part of the clustered PK (it will be the last of three columns) so I need to recreate all the indexes.
My DB is set for FULL recovery mode ALLOW_SNAPSHOT_ISOLATION ON. I've tried two methods so far.
Method 1:
BEGIN TRANSACTION
CREATE TABLE dbo.Tmp_copyoftablewithnewfield
(
) ON PRIMARY
IF EXISTS(SELECT * FROM dbo.originaltable)
EXEC('INSERT INTO dbo.Tmp_copyoftablewithnewfield (<original fields>)
SELECT <original fields> FROM dbo.originaltable WITH (HOLDLOCK TABLOCKX)')
GO
DROP TABLE dbo.originaltable
GO
EXECUTE sp_rename N'dbo.Tmp_copyoftablewithnewfield', N'originaltable',
'OBJECT'
GO
<recreate PK constraint>
<rebuild indexes>
COMMIT
Pro's: Lets me add the new field in the spot I'd like it (not a big deal)
Con's: Tons of wasted space and time. It took about 15 hours.
Method 2:
SET XACT_ABORT ON
GO
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE
GO
BEGIN TRANSACTION
<drop PK constraint>
<drop indexes>
ALTER TABLE [dbo].[originaltable] ADD
[newfield] [tinyint] NOT NULL CONSTRAINT [DF_originaltable_newfield] DEFAULT
((1))
<recreate PK constraint>
<rebuild indexes>
COMMIT TRANSACTION
Pro's: No making a copy of the entire table taking up 200GB more space in the db data file
Con's: My tempdb grew to accomodate the row versioning info for every row in the 200GB table. It took over 30 hours.
A lot of time and disk space is wasted with both.
Since the db is going to be unavailable to users I have some flexibility here. I was considering turning ALLOW_SNAPSHOT_ISOLATION OFF and then trying method 2 again which should stop the versioning in tempdb and then turning it back on.
I was also curious if setting the database recovery mode to SIMPLE would cut down on db log usage and then I could set it back to FULL when done.
Do these really need to be in a transaction? If there's some hardware failure or something unexpected I can just restore from backup and do the conversion again. If the presence of the transaction itself is causing more disk usage for logging or any other slowdown, I think I'd rather do without.
Given the amount of time this conversion takes, I wanted to get some
feedback other than "just try it" before doing any new tests.
Thanks.

Hi,
I'm merge replicating a SQL Server 2005 database (publisher) to SQL Compact databases (subscribers) on mobile devices. I understood that I could add a "not null" column to a replicated table on the server as long as I specified a default value, but it seems this is not possible. I ran the following script on the server database:
ALTER TABLE Activity ADD ActivityRequiresProject bit not null default(0)
which executed OK. When I went to synchronize the db on the mobile device I got the following error:
Alter table only allows columns to be added which can contain null values. The column cannot be added to the table because it does not allow null values.
The SQL statement failed to execute. If this occurred while using merge replication, this is an internal error. If this occurred while using RDA, then the SQL statement is invalid either on the PULL statement or on the SubmitSQL statement. [ SQL statement = alter table "Activity" add "ActivityRequiresProject" bit not NULL constraint "DF__Activity__Activi__4A47DDAE" default ( ( 0 ) ) ]
Does anyone know if this is a valid error? Is is possible to add a not null column with default, and if not how do I update the schema on a replicated database?
Regards,
Greg
