I have a table with a identity column in sql server 7 database. Now i need to update this identity column. Directly i couldn't able to update this column since it is an identity column. So, i like to drop this identity nature first and then update it is easy to update it. For this purpose, I need a Transact-sql script. Please Let me know if you have any thoughts on this. Thanks.

The statement:

returns a syntax error.
Thank you,

Is there any way to remove the IDENTITY property of a column? I originally used it, but it caused so many headaches with ADO.NET that I've decided to just increment the darn things manually. So I want to turn it into just a normal integer column.
If there's no direct way, can someone suggest a quick way to create a new column, copy all the old values into the new column, change the primary key to the new column, and drop the old column?
Thanks.
Hi,
I am having problem in bulk update of a sql server table haning identity column from a datatable( has no identity column) using sqlbulkcopy. I tried several approaches, but it does not show any error nor is the table getting updated. But the identity value seems to getting increased every time.
thanks.

I have to drop foreign key constraint from one table. How can I do that? Is it possible?

Is it possible to add a foreign key constraint on the table once it has a data?
Hi,
Any body please give me any reference to the C# code, how to drop a database on SQL SERVER CE.
thanx and regards

Pros-------* Can optimize the hell out of the database because it does not have toaccomodate different OSes* Code is probably cleaner - not littered with 80 million #ifdefs* No need to write the code to deal with various filesystem conventionsCons--------* Most cheap webhosts are unix-based (I think). You can use Oracle as aprofessional and still do your personal home hacking on oracleregardless of whether personal hosting is done on windows or unix. Notso with MS SQL.

i export tables from Local to Online Server But some tables have a column with Identity=True
But after export tables that Property is not True How I can change it True With Query Analyzer????????/
As a general rule most of the .net code I see with the transaction manager is something like
create transaction scope
do db stuff
commit or roleback in the catch block if a deadlock occurs
my question is does it make sense to retry the db operation if a deadock happens with some sort of spinwait before giving up?
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 table of three column first column is an ID column. However at creation of the table i have not set this column to auto increment. Then i have copied 50 rows in another table to this table then set the ID column values to zero.
Now I have changed the ID column to auto increment seed=1 increment=1 but the problem is i couldn't figure out how to update this ID column with zero value set to each row with this auto increment values so the ID column would have values from 1-50. Is there a away to do this?
Ok,I just need to know how to get the last record inserted by the highestIDENTITY number. Even if the computer was rebooted and it was twoweeks ago. (Does not have to do with the session).Any help is appreciated.Thanks,Trint

I'm in a middle of a project where replication established between Oracle 8i and SQL server 2005. Now we need to drop one column from on of the tables replicated from Oracle side. My question : Is there anyway I can do this in Oracle and automatically reflected on SQL server? If not what is the proper steps to do it. Realy appreciate your fast response.

I have two tables having one row identifier column each of int datatype. Both these columns are part of the respective primary keys. Now as a part of my process, i'm inserting one small part of data from one table to another table. This was working fine but suddenly started getting error like
Violation of PRIMARY KEY constraint 'PK_TargetTable'. Cannot insert duplicate key in object 'DW.TargetTable'. The duplicate key value is (58544748).First I checked with DBCC CHECKIDENT with NORESEED and found that there is difference in the current identity value and current column value. I fixed it by running DBCC CHECKIDENT. But to my surprise again got the same issue. interesting thing is that the error comes after inserting 65466 records.
Is there a way to reseed the Identity column in SQL Server Compact Edition? The following command does not appear to work DBCC CHECKIDENT (Table_Name, RESEED, 0) and I cannot seem to TRUNCATE the table either. Not sure if table truncation is even supported.
I apologize in advance if this is something obvious I've missed ... fresh eyes/brain and all that.
If I have a table that is using a particular partition scheme/function, is there a quick and easy way to determine which column of that table is being used for partitioning? We're examining a number of legacy structures and we're hoping to reduce the time it's going to take us to get the report management wants.
Thanks.
Hi, All:Please help. I use sql server as back end and Access 2003 as front end(everything is DAO).A table on SQL server has an identity column as the key.We have trouble on adding records to this table using the following SQL.strSQL = "INSERT INTO myTableOnSQLServer (A, B, C, D, E) SELECT A, B, C, D,E FROM myTableonAccessLocal"db.execute strSQLThe schema of the table "myTableOnSQLServer" and the schema of the table"myTableonAccessLocal" are all the same except that the "myTableOnSQLServer"has an identity column (ID). The key of the "myTableOnSQLServer" is "ID" andthe table "myTableonAccessLocal" does not have a key.When we try to run the query, it gives errors indicating the key is violatedor missing.Should I figure out the autonumber for it first and then add to the SQLserver table?Many thanks,HS

I am trying to use the identity data type ( column)
I am using examples from the book and management studio in sql server 2005.
I am using the identity property for the customer Id in customers table.I accidentatly executed the querry twice and I had two same record with different customer id numbers of 1 and 2 . I realised the problem and I had to delete the second record.
The problem is now even if I have deteted the 2nd record with customer id 2 , when I insert a new record the identity value ( customer Id) increments with a number after the value I deleted. i.e if I deleted a second row with customer id 2 ( identity 2) when I enter a new record it enters with a customer id of 3 and whenever i add a new record it increments from there.
So instead of first record have cust id 1 and second record customer id 2 etc , I get first record with cust id 1 , second record with cust id 3 , third record cust id 4 etc.
How can I get rid of this wrong values of identity values whenever I delete a record and try to add a new record?
Thanks

With SQL Server 2005, its quite easy to get by creating and insert statement on the tabledapter ( Insert statement followed by a select statement where identitycolumn = scope_identity())
How do this is sql everywhere??

I have the following 2 Query's - case when Table has no Identity Column and other with identity Column . I am planning to make it to single Query .

I am using following queries in a stored procedure.This stored procedure is executed through a dot net application.

I am extremely new to database design, and I ran into a problem that I know comes up often, however has many opinions...
Basically I have a table that is going to have 50+ columns. The natural key on this table is actually 8 columns wide, 4 of them being Varchar columns by default. (varchar(50)'s).
I have added an identity column, (1,1) to the table, however I put the clustered index on the 8 natural keys... My plan is to rebuild the clustered index once nightly when the system isn't in use (after 7 pm).
I know others would say it would be better to have the clustered key on the 1,1 column and then add indexes on the other 8 fields... However I don't quite understand why honestly...
Every single query against this table will use the 8 columns, and will NOT use the Identity column (1,1) because they are calls from other systems that do not know the Identity column....
Therefore if your database is set up for query speed, and every single query has to have a value for 8 columns to get a valid result, does it make sense to put a clustered index over the 8 columns?
If not why? Why is putting a clustered index on an identity column (that will literally never be used in a query) a better solution?
I orginally had my project ID specified as an Int and the properties set as identity specification that would automatically fill in the ID field however I have now changed it as the ID needs to be specified by the user but now when i update a project the ID isnt seen as the identity so whatever i do affects other records not just the one i select.
it is now defined as an nvarchar but i dont know how to set that as the identity so that each record can be edited seperately, can someone please help this is really urgent!!
Im using visual web developer express with sql server, please please help!
Hi all,
I had a table with two columns one identity field and second with foreign key constraint.
If my insert statement conflicted with COLUMN FOREIGN KEY constraint. My identity column getting auto incremented. But insert statement throws an error message stating that the statement has been terminated.
To be more clear,
identity_col1 col2
------------- ----
1 100
2 500
3 450
Suppose here I get an error:
Server: Msg 547, Level 16, State 1, Line 1
INSERT statement conflicted with COLUMN FOREIGN KEY constraint 'fk_ordercode_col2'. The conflict occurred in database 'pubs', table 'orders', column 'col2'.
The statement has been terminated.
I inserted next value
5 550
6 700
Instead of 4 I get value 5 in identity_col1.
Any help will be highly appreciated.
Thanks,
venkat.
I'm working with a third-party database (SQL Server 2005) and the problem here is the following:
- There are a bunch of ETL processes that needs to insert rows on a table (let's call this table T) and at the same time, an ERP (owner of T) is up and running (reading, updating and inserting on T).
- The PK of T is an Integer.
Today all ETL processes uses (select max(ID) + 1 from T) to insert new rows, so just picture the scenario. It is a mess! Everyday they get duplicate key error when 2 or more concurrent processes are trying to insert a row (with the max) at the same time.
Considering that I can't change the PK, what is the best approach to solve this problem?
To sum up:
* I need to have processes in parallel inserting on T
* I can't change anything on T
* The PK is NOT an Identity
ID A B C AVG

1 08 09 10 -

Hi all,
The requirement is to have a table say 'child_table', with an Identity column to refer another column from a table say 'Parent_table'..
i cannot implement this constraint, it throws the error when i execute the below Alter query,
ALTER TABLE child_table ADD CONSTRAINT fk_1_ct FOREIGN KEY (child_id)
REFERENCES parent_table (parent_id) ON DELETE CASCADE
the error thrown is :
Failed to execute alter table query: 'ALTER TABLE child_table ADD CONSTRAINT
fk_1_ct FOREIGN KEY (child_id) REFERENCES parent_table (parent_id) ON DELETE
CASCADE '. Message: java.sql.SQLException: Cascading foreign key 'fk_1_ct' cannot be
created where the referencing column 'child_table.child_id' is an identity column.
any workarounds for this ?
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;
