SQL Alter Table Statement With Bit's

Oct 13, 2000

Hi List,

I am trying to add a column with Alter Table, like this:

ALTER TABLE myTable ADD
newColumn bit DEFAULT 0 NOT NULL

This works fine with SQL-server 7, but I get this error in 6.5:

'ALTER TABLE only allows columns to be added which can contain nulls. Column 'newColumn' cannot be added to table 'myTable' because it does not allow nulls.'

I also found this in the help files:

'Columns added to a table must be defined as NULL. When a column is added, the initial value for the column will be set to NULL. This restriction forces the ALTER TABLE statement to fail if the bit or timestamp datatypes are used.'

My question, is there any other way to do this on 6.5 ?

Estimate Log Space For Alter Table Statement

Jan 31, 2007

My client's website database is hosted by a third party. I need to alter one of the column definitions for the largest table in the database. Unfortunately, the transaction log fills up if I try to alter the table. I've done all the usual stuff like truncating the log, etc., but the simple fact is that the operation requires more log space than we have available. Therefore, we need to purchase additional disk space for the database.
What I'm looking for is a way to roughly estimate how much log space will be required to alter this table so that we purchase enough but not too much additional space. The table has an identity primary key and 4 other single column indexes: one int, one datetime and two varchar(30) columns.
Any suggestions? Thanks in advance.

Check For Column Existance Before Alter Table Statement

Feb 14, 2000

Hello all,

I am trying to add columns to several tables in a singular database. I want to check to see if the column exists in a given table first before executing the alter table command so that I can skip that command if the column already exists, and avoid aborting my script prematurely. I can't seem to find a way to check for the column's existance. Any suggestions?

May 28, 2002

Hello.

I'm trying to create a batch sql script which first alters some existing tables via the ALTER TABLE command, I then want to alter some existing stored procedures via the ALTER PROCEDURE command within the same batch. I have found that I can encompas the alter table scripts within a conditional IF EXISTS (Begin/End) but not the alter procesdure scripts. I have looked in reference material and have found nothing to suggest this type of operation is not possible. Is this possible? Is this a know bug fixed by a service pack?

I am using the sa account. Any ideas on how to fix this??

Can't Rollback Alter Database Statement DDL Trigger

Feb 26, 2008

Recently I created a DDL Server-scope trigger using the following:

create trigger stop_alter_database on all server
for ALTER_DATABASE
as
rollback;
print 'database change stopped by stop_alter_database';
go

Then I ran the following script:

alter database [test] modify file (name=test', maxsize=2028mb);

The result was:

Msg 3609, Level 16, State 2, Line 1

The transaction ended in the trigger. The batch has been aborted.

database change stopped by stop_alter_database

The problem is that when I checked the max size of the data file it had changed. So, the statement was never rolled back. Is there something I'm missing because I can't find any documentation or articles that state the inability to rollback alter database statements. Whats going on?

DB Engine :: Does ALTER COLUMN Statement Converts Data?

Oct 8, 2015

I've some huge table (over 100GB each), these table contain column of NTEXT, IMAGE. Application team needs to change these data types to VARBINARY(MAX), I've tested the modification in our lab and I noticed that the operation has been almost immediate so, I think that DB Engnine has not converted the existing data in the column but it has simply changed the definition of the column.

Or maybe NTEXT and IMAGE can be transparently converted into VARBINARY(MAX)?

Anyway, I want to be sure that the modified table is "coherent" I don't want that at a given point SQL Server tells me that some data is not readable.

How To Alter Column Length Of The Master Table Along With The Slave Table?

Aug 13, 2006

In SQL Server 2005,here are two tables, created by the following SQL Statements:

CREATE TABLE student(
ID CHAR(6) PRIMARY KEY,
NAME VARCHAR(10),
AGE INT
);

CREATE TABLE score(
ID CHAR(6) PRIMARY KEY,
SCORE INT,
FOREIGN KEY(ID) REFERENCES student(ID)
);

For the length of Column ID is not enough, So I want to alter its length.The alter statement is:

ALTER TABLE student ALTER COLUMN ID CHAR(20)

For the table student is referenced by table score, the alter statement can not alter the column of the table student, and the SQL Server DBMS give the errors.

But, I can manually alter the length of the column ID in SQL SERVER Management Studio. How to alter column length of the master table(student) along with the slave table(score)?

Thanks!

ALTER TABLE SWITCH PARTITION On A Replicated Table

Apr 10, 2007

A customer wants to implement table partitioning on a replicated table.

They want to hold 13 months of data in the table and roll off the earliest/oldest month to an identical archive table. The table has a date field and partitioning by month makes sense all around.

So SWITCH PARTITION is the obvious solution to this, except for the fact that the table is replicated (transactional w/no subscriber updates).

What are his architectural or practical solutions to using table partitioning and replication?

thx
