This has always puzzled me, so I really just wanted to know if it's possible through T-SQL.
TableA has 3 columns:
ColumnA
ColumnB
ColumnD
Is there anyway through T-SQL to add a new ColumnC *between* ColumnB and ColumnD.
ALTER TABLE TableA
ADD ColumnC [varchar](1)
Thanks.
Hi guys,
If I have a temporary table called #CTE
With the columns
[Account]
[Name]
[RowID Table Level]
[RowID Data Level]
and I need to change the column type for the columns:
[RowID Table Level]
[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 also tried:
ALTER TABLE #CTE
MODIFY
[RowID Table Level] INT IDENTITY(1,1),
[RowID Data Level] INT;

Hi I’m trying to alter a table and delete a column I get the following error. The object 'DF__Morningst__LastU__19EB91BA' is dependent on column 'LastUpdated'.
ALTER TABLE DROP COLUMN LastUpdated failed because one or more objects access this column. I tried deleting the concerned constraint.

i have a table
table1
column1 int not null
column2 char not nul
column3 char
i want to script a change for table1 to alter column1 to be the table identity column. not primary.
I have created a table as below mentioned. Then I want to alter the ID column as identity(1,1) without dropping the table as well as losing the data.
create table dbo.IdentityTest
(
id int not null,
descript varchar(255) null,
T_date datetime not null

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!
I have the table table_x:
col1 INT PRIMARY KEY
col2 VARCHAR
I want to add col3 between col1 and col2. In MySQL it's done with the following query:
ALTER TABLE table_x ADD col3 VARCHAR( 10 ) NOT NULL AFTER col1 ;
In sql server all i can do is to add the column to the end of table. Is there a way to insert a new column in the middle or to move a column to left/right?
I would like to alter a table column from char(10) to char(5). I issue the command as :
Alter table mytable alter column mycolumn char(5)
It returns :

String or binary data would be truncated.
How can I perform this task?

In MS SQL Server, I have the following tables with some data in it.create table table1 (column1 varchar(32),column2 int not null,column10 varchar(255),.....primary key (column1, column2),);create table table2 (column1 varchar(32),column2 int not null,column20 varchar(255) not null,....foreign key (column1, column2) references table1(column1, column2));Now, I need to change the all column types from varchar to nvarchar tosupport internationalized character set.I am able to do so, for columns column10 in table1 and column20 oftable2 without any problems by using command:"alter table table1 alter column column10 nvarchar(255);"But, when I try the similar thing for column1 of table1/table2, amgetting one error message saying like: "ALTER TABLE ALTER COLUMN failedbecause one or more objects access this column". I guess, this iscoming because of foreign key relationship between the tables.NOTE: While defining the table2, for foreign key I have not specifiedanything like "on update cascase" ...etc.How can I resolve this issue? Any suggestions/solutions are reallyhelpful to me. Thanks in advance.

I am modifying a table and some of the columns are changing. The following syntax is resulting in errors. What am I doing wrong?
ALTER TABLE [EDB].[SQL_test]
ALTER COLUMN EDBR_Nb EDBR_Nm varchar(10)
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?
I want to alter my all tables to change the name of all columns.
Â
I need this because all column names were created with space and I want to remove the space for future work .
For example – In Table Customer there is a column name [Cust_Id ] and I want to change it with [Cust_Id]
When you use "Alter Table add Column", it adds the column to the end of the list of fields.
How do you insert the new column to position number 2 for instance given that you may have more than 2 columns?
Create table T1 ( a varchar(20), b varchar(20), c varchar(20))
Alter table add column x varchar(20)
so that the resulting table is
T1 a varchar(20), x varchar(20), b varchar(20), c varchar(20)
Can this be done programmatically?
I inherited a system which has an index on a set of columns which allow more than 900 bytes of data in it. We know one of the fields can be shortened to shrink the potential key size below 900 bytes.
The problem is the table is about 120m rows, and the index currently on that column is seeked (sought?) on about 2.5m times a day.
At its simplest, I want to drop the existing index, alter the column to shrink the varchar size, and then rebuild the index on the newly shortened column.
On a smaller, less used table, I might just do this in outside of business hours and call it a day, but I'm concerned that this will take a long time and block a lot of operations.
1) IIRC, shrinking a column, unlike widening it, is much more expensive, even if there are no values which would actually end up trunacted. Is this right?
2) I did a few tests on some other smaller (2+ m) row tables and was still able to select data out of the table. I don't think this covered all the read scenarios, but are there known scenarios which would simply not work during an index build?
3) I haven't yet tried DML operations to the table while it's doing either the column update or an index build. what scenarios would or would not be blocked?
Working on partitioning a few large tables. One of the tables included a text column and the €œTEXTIMAGE_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 €œlob_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
I ran this query against the pubs database and it runs successfully
ALTER TABLE publishers ALTER COLUMN state CHAR(25)
I change the table & field names for my db as follows:
ALTER TABLE customquery ALTER COLUMN toclause CHAR(25)
and run against my database and I get the following error - Incorrect syntax near 'COLUMN'.
My column name is correct - I don't know why it would run fine against pubs, but not my db. I do not have quoted identifiers turned on. I have tried using [] around my column name [toclause], but that didn't change anything. Any help would be appreciated.
Thanks.
I have a table with a column defined thus: LOCNumber Varchar(100) in atable called Bookdata.If I execute ALTER TABLE BookData ALTER COLUMN LOCNumber varchar(100)on the table, does any work get done on the table and column?Or does SqlServer know that the column is already varchar(100) andnothingneeds to be done?If it does do some work, how do you tell it not to run this as it isalready a varchar(100) column. Right now my program just blindly doesthis ALTER TABLEstatement regardless of any conditions. Is this a potential problem?Thanks for any help.

Well here's one of those excruciatingly simple obstacles:
In SQL Server 2005 (Mgmt Studio): according to BOL, the syntax to set a default value for an existing column is:
ALTER TABLE MyCustomers ALTER COLUMN CompanyName SET DEFAULT 'A. Datum Corporation'
However, when I Check:
alter table CommissionPayment alter column Amount Set Default 0
I get the error message:
"Incorrect syntax near the keyword 'Set'."
No other combinations of this syntax work.
Help! What am I missing?
Hi smart people!
I would like to know how to alter a column to have a default value. For instance I have a column AreaCode Char(3) in a table. I have data in the table and now I want to add a default value of '123' to the AreaCode column.
I tried the following but did not work.
Alter Table Phone
Alter Column AreaCode Char(3) Default '123'
Can we even do it using SQL?
