How do you alter a table to set a column which is currently int, to int not null?
I have already set all values to either 0 or 1.
Why can't I use:
Alter table myTable alter myCol int not null default(0)
I get a syntax error on the word default. If I remove "default(0)" then the command executes ok, but my Inserts don't work because there's no default value.
Dear folks,
please tell me the query for altering a column from not null to null
Vinod
I have a table with a TEXT column that allows nulls.
Now I need to change it, and make it NOT NULL, but I Can't
ALTER TABLE BUSINESS_UNIT_LANG
alter column VISION text not null
And I get:
Server: Msg 4928, Level 16, State 1, Line 1
Cannot alter column 'VISION' because it is 'text'.
Is it impossible to make a text column NOT NULL when it accepts NULLS ?
All rows and columns are populated, in consequence there isn't any col with null values
Any idea?
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:

Thanks in advance,

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;

I have a stored procedure that adds constraints from a variable:
ALTER procedure [dbo].[addMyConst](@txtAuto_ourlim money OUTPUT,@txtGen_ourlim money OUTPUT)ASEXECUTE('ALTER TABLE [dbo].[tbl1] ADD CONSTRAINT DF_auto_ourlim DEFAULT ' + @txtAuto_ourlim + ' FOR Auto_ourlim')EXECUTE('ALTER TABLE [dbo].[tbl1] ADD CONSTRAINT DF_Gen_ourlim DEFAULT ' + @txtGen_ourlim + ' FOR Gen_ourlim')
This works fine unless one of the variables is null or empty. Then I get the error: "Incorrect syntax near the keyword 'FOR'
Evidendly SQL Server Express sees "....DEFAULT + + FOR..." but I don't know.
I've fiddled with this a long time and haven't a clue how to fix it. Any help would be appreciated. Thanks, Steve
how can you alter a table so that you can add a default value whenever the field is NULL? for example, whenever the table is brought up in a query, NULL is replaced with UNKNOWN

I have existing table which is having Set Quoted Identifier Off and Set Ansi Null
Now I want to change those setting so Is there any alter statement for the same?
Also Let's say At my database level If those settings are off and If I convert it to ON then It is not taking effect on existing tables SP which are already build.
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

i want to script a change for table1 to alter column1 to be the table identity column. not primary.
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.

It's giving me an error while I'm trying to change column value from not null to null..
'tblid' table
- Unable to modify table.
Cannot insert the value NULL into column 'ValidID', table 'Xe01.dbo.Tmp_tblid'; column does not allow nulls. INSERT fails.
The statement has been terminated.
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?
if i have structure of table like a,b,c,d,e column then
i want to alter one more column x b/w b and c column, so that
a,b,x,c,d,e
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?
Thanks
Is there any way to alter a column's name using Transact SQL and not the GUI interface?

How can you rename a column in a table (from c# code, preferrably from a SQL script command) without deleting the column and re-creating it with a new name?
View 5 Replies View RelatedHi
I had a text type not null column which i wanted to change to a null column.Writing a simple alter statement gave me an eror cannot change text type column so i tried to rename the original column create a new column with the same name and allowing nulls on it and then copying the contents of the renamed column to the new column and finally deleting the renamed column.
EXEC sp_rename 'TableName.ColumnName', 'ColumnName_old', 'COLUMN'ALTER TABLE TableName ADD ColumnName text NULLUPDATE TableName SET ColumnName = ColumnName_oldALTER TABLE TableName DROP COLUMN ColumnName_old
However when i tried to execute these statements in query analyser on the Update statement it gave me the error that ColumnName_old does not exist.
However then I tried to execute these queries one by one I was able to do that.
Can anybody tell me whats causing the queries to not be executed all at once without giving the ColumnName_old does not exist error cause I wanted to run them on live dbs.
any help would be appreciated.

i am altering an int column to identity:
where is something wrong here?
error:
Server: Msg 156, Level 15, State 1, Line 1
Incorrect syntax near the keyword 'IDENTITY'.
statement:
ALTER TABLE Navigation Alter column [Navigation_ID] int IDENTITY(1,1)
I'm attempting to remove the IDENTITY property from a column using the ALTER command but can't seem to find the right syntax. I've tried every conceivable combination I can think of. I can add the property to a column that doesn't have it.
It's easy to do in Enterprise Mgr., but I want to script the change.
I really don't want to drop the table and rebuild if I don't have to.

I've done some research on setting the default value of a column and found the following code:
ALTER TABLE [table1] ALTER COLUMN [column1] SET DEFAULT 0
I am trying to set column1 within table1 to a default value of 0, column1 is an int data type. But it doesn't work within MS SQL SERVER 2000.
Can anyone tell me what's wrong?
Hello All,
There is a table A in SQL. One of the column of A was IDENTITY before and was getting referenced in other table B.
During migration to SQL 2005, I removed the IDENTITY constraint and imported all the data from 2000 to 2005. Now I have to deploy the IDENTITY back to the column. I am getting an error while executing the code:
ALTER TABLE TableA
ALTER COLUMN ColumnA
ADD CONSTRAINT IDENTITY(445,1)
Can anyone tell me where I am going wrong? Or if there is any other way to do it. There are 50+ tables I need to do the same.
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?
hello experts,
Any body know what is the query for modifying the identity column in a table? i mean modifying from IDENTITY column to int colum or VICE-VERSA
Thanks
