Adding Column To A Table Before An Existing Column
Mar 30, 2004I 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.
SQL Tools :: Adding Column To A Table Causes Copying Data Into Temp Table
Sep 23, 2015If 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.
Adding Column To Table
Dec 18, 2001I 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?

Feb 24, 2003Can 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?

Adding And Populating A Column To Existing Table
Dec 5, 2005Sorry 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?
Adding Column With Primary Key In Existing Table
Jan 21, 2014I want to add new primary key into existing table which already has a primary key. But,I do not want to remove the old primary key, since there are many records and the old primary key also have relationship with other table
When I am using this query:
alter table hem154
add indexNO uniqueidentifier default newid()
alter table hem154
add CONSTRAINT pk_hem154_indexNo PRIMARY KEY (PK_indexNO)
go
Note:
Hem154 ~ Table name
indexNo ~ Column Name
I get this runtime error:

Table 'hem154' already has a primary key defined on it.
Msg 1750, Level 16, State 0, Line 1
Could not create constraint. See previous errors.
Adding A Column To VLDB 200GB Table
May 1, 2007The 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.
Adding A Not Null Column To Replicated Table
Apr 23, 2007Hi,
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

Adding Dataset Column Values To My Table At The End

I am mapping an entity from SQL 2005 to another entity in another system on SQL 2000. Since the destination system has its own ID generator, I want to keep the generated ID for each row of my table in a column of my table in SQL 2005. The new column is in the dataset now , but I don't know how to update my table to have that column values (The OleDbDestination just insert new items.)

Problem Adding NOT NULL Column To Replicated Table
Jan 15, 2003I'm new to replication and am trying to determine the best approach to add a column (NOT NULL with no DEFAULT) to a replicated table. The only success I have had is if I do the following:
Delete entire Subscription
Delete entire Publication
Add column to table
Create new Publication
Create new Subscription
Run SnapShot
The problem with this approach is that each step affects the entire database and not just the modified table. I think it is inefficient to redo replication for a simple object change. What am I missing? Is there a way to only replicate the changes made to the one table without having to run a SnapShot for the entire publication?
Keep in mind the column must be defined as NOT NULL and cannot have a Default.
Thanks, Dave

SQL 2012 :: Adding Column To A Table Over Linked Server
Apr 22, 2015I have a situation that I need to add a field to a table over linked server. The specifications of this is dynamic and it is being done in TQL / Stored procedures and this can not change. My code is generating the statement just fine and if I copy paste it to a new SSMS window and execute it WORKS.. The problem is I need to dynamically generate the statement (I am doing that just fine, I THINK). THEN I need to execute the statement IN THE SPROC, this part is not working.
Here is the code:
SET @AlterSQL = @DestinationServerName + '.[' + @DestinationDBName +'].' + @DestinationSchemaName + '.sp_executesql N'' ALTER TABLE '
+ @DestinationTableName + ' ADD ' + @TempColumn + ' int' + CHAR(39)
The above Creates this when I expose it via a PRINT statement:
addb15.[FSParallel].dbo.sp_executesql N' ALTER TABLE Node ADD ImportIdentity int'
After I create the statement I use:
EXEC @AlterSQL
And this returns the following error:
Msg 2812, Level 16, State 62, Procedure ETLDynamicImport, Line 244
Could not find stored procedure 'FSParallel.dbo.sp_executesql N' ALTER TABLE Node ADD ImportIdentity int''.

SQL Server 2008 :: Adding Column To Existing Replicated Table
Feb 9, 2015I have a scenario where I need to add a blank column to a table that is a publisher. This table contains over 100 million records. What is the best way to add the column? In the past where I had to make an update, it breaks replication because the update would take forever as jobs are continuously updating the table so replication can't catch up.
If I alter a table and add a column, would this column automatically get picked up in replication?
Adding An Auto-increment Column To Existing Table With A Particular Order
Oct 19, 2005Hello all,I'm using SS2K on W2k.I'v got a table say, humm, "Orders" with two fields in the PK:OrderDate and CustomerID. I would like to add an "ID" column whichwould be auto-increment (and would be the new PK). But, I would reallylike to have orders with the oldest OrderDate having the smallest IDnumber and, for a same OrderDate, I'd to have the smallest CustomerIDfirst. So my question is:How could I add an auto-increment column to a table and make it createits values in a particular order (sort by OrderDate then CustomerIDhere)?In the real situation, the table I want to modify has around 500krecords and the PK has 5 fields and I want to sort on three of them.Thanks for you helpYannick

View 3 Replies View RelatedPC SQL Server Table (with A Column Classified Unique) Synchronizes (using Merge) With 2 PPCs SQL Mobile Adding The Same Record
Aug 29, 2006Hi, I have a doubt about the behaviour of SQL Server 2005 in the situation I'm going to describe you.
Suppose that you have a SQL Server 2005 database on your PC, and suppose that this database has a table with a column classified as "unique" (so it's impossible for this table to contain 2 records having the same value in this column).
Suppose that you publish this database and you create 2 SQL Server Mobile 2005 subscriptions on 2 Pocket PCs.
Suppose now that the first PPC (using an embedded program) creates a record with a certain value for the column (and adds it to the table), and the second PPC makes the same thing (it inserts a record with the same column value of the first PPC).
At this point, you connect the 2 PPCs to your PC (one by one, of course), to synchronize (using merge replication) the databases...
WHAT HAPPENS??? Does an error raise?
Must you give a publication setting in which you say that, if this situation occurs, PC SQL Server holds the last (or the first, as you decide) record acquired? Is it possible?
Thank you very much
Indexing A Table With 80 Million Records
Mar 26, 2004i have a directory database with approx. 80 million records. i am feeding the database with bulk_insert. Indexing one of the fields took about 8 hrs. After indexing when i run queries with the indexed field the response time is under 1 sec. However if i run select queries with like on non-indexed fields it takes more than 2 mins. So i decided to index 4 other fields in the database and it looks like the indexing process is going to run for 2 days.
i am a novice in SQL database design and i am not sure if this is the best way to index the table. i am just using create index. Any suggestions / advice welcome.
Should I Split This 175 Million Record Table?
Jul 20, 2005Hello,We maintain a 175 million record database table for our customer.This is an extract of some data collected for them by a third partyvendor, who sends us regular updates to that data (monthly).The original data for the table came in the form of a single, largetext file, which we imported.This table contains name and address information on potentialcustomers.It is a maintenance nightmare for us, as prior to this the largesttable we maintained was about 10 million records, with lesscomplicated updates required.Here is the problem:* In order to do the searching we need to do on the table it has 8 ofits 20 columns indexed.* It takes hours and hours to do anything to the table.* I'd like to cut down as much as possible the time required to updatethe file.We receive monthly one file containing 10 million records that arenew, and can just be appended to the table (no problem, simple importinto SQL Server).We also receive monthly one file containing 10 million records thatare updates of information in the table. This is the tricky one. Theonly way to uniquely pair up a record in the update file with a recordin the full database table is by a combination of individual_id, zip,and zip_plus4.There can be multiple records in the database for any givenindividual, because that individual could have a history that includesmultiple addresses.How would you recommend handling this update? So far I have mostlytried a number of execution plans involving deleting out the recordsin the table that match those in the text file, so I can then importthe text file, but the best of those plans takes well over 6 hours torun.My latest thought: Would it help in any way to partition the tableinto a number of smaller tables, with a view used to reference them?We have no performance issues querying the table, but I need somethoughts on how to better maintain it.One more thing, we do have 2 copies of the table on the server at alltimes so that one can be actively used in production while we runupdates on the other one, so I can certainly try out some suggestionsover the next week.Regards,Warren WrightDallas

Will a SQL server database table with A half a million records in it be possible? We have tried to normalize the database to cut down on the size of the table but it all comes out to about a half a million records per table.
Any help is deeply appreciated.
