SQL Server 2008 :: Adding Column To Existing Replicated Table
Feb 9, 2015
I 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?

After i run the sql which adds some columns on one particular table.I am getting this Warning
Warning: The table 'usac499_499A' has been created but its maximum row size (9033) exceeds the maximum number of bytes per row (8060). INSERT or UPDATE of a row in this table will fail if the resulting row length exceeds 8060 bytes.

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

I'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

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?

I 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:
Msg 1779, Level 16, State 0, Line 1
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.

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

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.

Hello 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

I have a date column (not datetime) in SQL Server and the dates are in the format yyyy-mm-dd
I need to replace the date values with zero's so it looks like 0000-00-00
I can currently get the current date in to the column like this:
UPDATE TestTable_1
set datecolumn = CONVERT(varchar(10), GETDATE(), 10)
But instead of GETDATE() I need to enter the zero's like this: 0000-00-00
How can I do this?

I am getting inconsistent results when BULK INSERTING data from a tab-delimited text file. As part of my testing, I run the same code on the same file again and again, and I get different results every time! I get this on SQL 2005 and SQL 2012 R2.
We have an application that imports data from a spreadsheet. The sheet contains section headers with account numbers and detail rows with transactions by date:
AAAA.1234 /* (account number)*/
1/1/2015 $150 First Transaction
1/3/2015 $24.233 Second Transaction
BBBB.5678
1/1/2015 $350 Third Transaction
1/3/2015 $24.233 Fourth Transaction
My Import program saves this spreadsheet at tab-delimited text, then I use BULK INSERT to bring the data into a generic table full of varchar(255) fields. There are about 90,000 rows in each day's data; after the BULK INSERT about half of them are removed for various reasons.
Next I add a RowID column to the table with the IDENTITY (1,1) property. This gives my raw data unique row numbers.
I then run a routine that converts and copies those records into another holding table that's a copy of the final destination table. That routine parses though the data, assigning the account number in the section header to each detail row. It ends up looking like this:
AAAA.1234 1/1/2015 $150 First Purchase
AAAA.1234 1/3/2015 $24.233 Second Purchase
BBBB.5678 1/1/2015 $350 Third Purchase
BBBB.5678 1/3/2015 $24.233 Fourth Purchase
My technique: I use a cursor to get the starting RowID for each Account Number: I then use the upper and lower RowIDs to do an INSERT into the final table. The query looks like this:
SELECT RowID, SUBSTRING(RowHeader, 6,4) + '.UBC1' AS AccountNumber
FROM GenericTable
WHERE RowHeader LIKE '____.____%'
Results look like this:
But every time I run the routine, I get different numbers!
Needless to say, my results are not accurate. I get inconsistent results EVERY TIME. Here is my code, with table, field and account names changed for business confidentiality.
TRUNCATE TABLE GenericImportTable;
ALTER TABLE GenericImportTable DROP COLUMN RowID;
BULK INSERT GenericImportTable FROM 'SERVERGeneralAppnameDataFile.2015.05.04.tab.txt'
WITH (FIELDTERMINATOR = ' ', ROWTERMINATOR = '', FIRSTROW = 6)
ALTER TABLE GenericImportTable ADD RowID int IDENTITY(1,1) NOT NULL
SELECT RowID, SUBSTRING(RowHeader, 6,4) + '.UBC1' AS AccountNumber
FROM GenericImportTable
WHERE RowHeader LIKE '____.____%'

I have some huge tables (think 200+GB for a single table) which are excellent candidates for sparse columns. The tables have many columns which are defined with decimal datatypes (13,2) with a large percentage of them (over 50% in most cases- some as much as 99%) being 0.00. Since this is very expensive in terms of storage my idea is to set all the 0.00 values equal to NULL then set them as sparse. Across 100 or so identical databases, I have 5 such tables, with 20-40 columns in each table.
1.) three steps for each column in each table in each db.
Step 1: update table to allow for nulls
Step 2: update tabe set column=null where column =0.00
Step 3 update table set sparse columns
2.)
Step 1: Create entirely new table with sparse column definitions
Step 2: copy entire table, transforming 0.00 to null for affected columns via SSIS
Step 3: drop original table, rename new table to original name

I cannot figure out how to add a default constraint to an existing column. The syntax I'm using is :
ALTER TABLE table_name WITH NOCHECK
ADD CONSTRAINT column_name DEFAULT (0)
This gives me a syntax error.
The column was originally added with a default constraint of 1 to a 2.6 million row table.
I dropped the existing constraint and need to add the new default constraint of 0 for that column.
Anyone have any ideas? Thanks in advance.

I need to recover some data in a table but i'm not 100% sure the right way to do this safely.
I'll need to query the two tables to compare the before and after but how do i go about restoring/attaching the backup database to SQL without causing conflicts?
If I restore, I assume this would just overwrite which is obviously the worst thing that can happen. if i attach the backup, how does this affect the current live DB? how do i make sure that it's not getting accessed and mistaken for the live DB?
The SQL server is 2008 R2 running as a VM.

Is there a good way to add columns to a table type?
I built several procs which make use of table-valued-parameters, and they work pretty nicely, until I need them to accept additional columns. Then I have to drop all the procs that use them, alter the types, and rebuild all the procedures, which is a huge pain in the rear.
Is there any good way (built in, or custom) to alter the def of a table type that's used as a parameter to multiple stored procedures?

We are using push subscription using transactional replication. Is there a recommended value for retention period on distributionDb? We are using default value of 72 hrs and recently we saw an issue where data was not replicated with an error that subscription was inactive. When I searched, I fid that it is related to the retention period setting on distribution DB.

I want to add a computed field to an existing SQL table:
where Field1 is >0 and field2 is not null
set newfield = 'Y'
else set newfield = 'N'
I want to keep this existing table because I'm using it as the basis for an Access Report that is nearly complete.
BTW this table is the result of a DTS package that is comprised of several SQL executables so I need to be able to repeat this as part of a larger process.
Thanks!

Dear Friends,
what is best and quicker way to add 500 columns to existing table having 145 columns already.
Is there any way to avoid manual work of adding columns one by one in design mode or using script.
I have a TXT file (comma delimited) that contains all those columns names as a first row,but I am not sure if i can use DTS package to create table design having such sourcre TXT file.
Any advice?
Thanks,

I have a strange problem. I have a computed column in a replicated table, the Formula is as follows:
(isnull(hashbytes('SHA2_256',CONVERT([varchar](256),[AccrualReference],(0))),(0))) the column is also Persisted.
This gets around a case sensitivity issue and is used as the Primary Key column, which works well.The problem is that this table is then replicated to another server. On the subscriber the value of this computed field is being returned as 0x00000000 for every row, so this must be the ISNULL function doing its job. But why? The AccrualReference is the true PrimaryKey and is never NULL.
If I remove the computed specification and set the field up as varbinary(64) the value then gets replicated. This then means maintaining a different table schema for in excess of 500 tables.
