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)
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;

The system in this part of the application is intended to be highly configurable and column names on the table being operated upon can change.

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. But the next time I get the same error with a different constraint name. I want to find out if I can dynamically check the constraint name and delete it and then drop the column. Can anyone help.IF EXISTS(SELECT 1FROM sysobjects,syscolumnsWHERE sysobjects.id = syscolumns.idAND sysobjects.name = TablenameAND syscolumns.name = column name)BEGIN EXECUTE ('ALTER TABLE tablename DROP CONSTRAINT DF__SecurityM__DsegL__08C105B8')EXECUTE ('ALTER TABLE tablenameDrop column columnname)ENDGO
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.
View 2 Replies View RelatedHello 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 have two tables:
dtr
dataid........Subtype
data
docid....mimetype
I need to change the value of column mimetype in table data, but only for these entries which have the value 144 in column "Subtype" in table dtr.
Here is my sql:
with cte as (
select
DataID,
SubType,
MimeType
from dtr A1, data A2
where A1.dataid=A2.Docid And A1.Subtype='144'
AND
A2.mimetype='application/news-message-id'
)
update cte set MimeType = 'application/x-outlook-msg'
I've tested it and it works. Do you see any problems with this SQL?
As updates are risky I'll do a database backup. Is it possible to get all changed entries so that I can track my update, because I don't have a report about the changes? Maybe that everythin is transferred to an output file?
Hi,
I have a SP which returns a select query on a temp table so I get to choose column names
when I create the #table.
Can I determine column names myself based on the results of another query (in the SP)
before, or (preferably) after I create the #table and populate it.
My query is used to bind to a datagrid so I could use....
dataGrid.Columns[index].HeaderText and set it to a particular output parameter, but I want
to keep the code in the SQL.
Cheers
Hi All,
I am using SQL Server 2000 Enterprise Edition fully patched. Database is in Simple Recovery mode.
I need to change a column's data type from "int(4)" to "smallint(2)". I know for sure that there will be no data (precision) lost, because I know the possible values that this column could have.
My problem is that the table I am dealing with has 600,000,000 records in it. I dropped all indexes before I tried to alter the table. But still it is taking forever and filling up my 280GB disk with transaction log file.
I know that in Oracle, if I want I can turn off logging and do these kind of modifications relatively faster.
I was wondering if there is a way of disabling logging before running this alter command.
What is the best practice to handle a situation of this sort?
I appreciate your help.
Thanks in advance,
Sinan Topuz
