How can I alter a table turning ON or OFF an IDENTITY field ?
for example:
if I had my DB with Client_ID as an I IDENTITY field and for some reason it has
changed to just INT (with no IDENTITY) - how can I tell it to be IDENTITY field again ?

Does anyone knows an article on database planning ?
(I wanna know when should I use the IDENTITY field)
Hi people,I?m trying to alter a integer field to a decimal(12,4) field in MSACCESS 2K.Example:table : item_nota_fiscal_forn_setor_publicofield : qtd_mercadoria integer NOT NULLALTER TABLE item_nota_fiscal_forn_setor_publicoALTER COLUMN qtd_mercadoria decimal(12,4) NOT NULLBut, It doesn't work.

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:
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2093921&SiteID=1
Thanks in advance,
Aldo.
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;
While I have learned a lot from this thread I am still basically confused about the issues involved.
.I wanted to INSERT a record in a parent table, get the Identity back and use it in a child table. Seems simple.
To my knowledge, mine would be the only process running that would update these tables. I was told that there is no guarantee, because the OLEDB provider could write the second destination row before the first, that the proper parent-child relationship would be generated as expected. It was recommended that I create my own variable in memory to hold the Identity value and use that in my SSIS package.
1. A simple example SSIS .dts example illustrating the approach of using a variable for identity would be helpful.
2. Suppose I actually had two processes updating these tables, running at the same time. Then it seems the "variable" method will also have its problems. Is there a final solution other than locking the tables involved prior to updating them or doing something crazy like using a GUID for the primary key!
3. We have done the type of parent-child inserts I originally described from t-sql for years without any apparent problems. (Maybe we were just lucky.) Is the entire issue simply a t-sql one or does SSIS add a layer of complexity beyond t-sql that needs to be addressed?

I am having problem when performing the alter table switch. Both tables are identical and have pk.
ALTER TABLE SWITCH statement failed. There is no identical index in source table 'LocalDeltanet.dbo.testresults' for the index 'PKIDX_testSummary' in target table 'LocalDeltanet.dbo.testresults_part' .
CONSTRAINT [PKIDX_testSummary] PRIMARY KEY CLUSTERED
( [testresult_id] ASC )
WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON)
ON TResultsScheme (testresult_id) ) ON TResultsScheme (testresult_id)
I have performed the function on other tables successfully, but this is the first that has an identity column involved. Is there anything special that needs to be done?
[testresult_id] [int] IDENTITY(1,1) NOT NULL,
I want to insert a new record into a table with an Identity field and return the new Identify field value back to the data stream (for later insertion as a foreign key in another table).
What is the most direct way to do this in SSIS?
TIA,

P.S. Or should I pass the identity value back in a variable and not make it part of the data stream?

I have 2 tables - tblOrders and tblOrderDetails. Every time an order is placed, 2 INSERT statements are executed. The first one enters the general order and customer information in the tblOrders table:INSERT INTO tblOrders (custname, custdetails, orderdate) VALUES (@custname, @custdetails, @orderdate)The primary key in this table is OrderID which is an Identity column. This is the foreign key in the tblOrderDetails table.I'm trying to get the Identity value from the first INSERT statement to use in the second INSERT statement:INSERT INTO tblOrderDetails (orderid, productid, productcost) VALUES (@orderid, @productid, @productcost) How do i obtain this value and how would I supply it to the second INSERT statement?
View 3 Replies View RelatedHi, I have the lovely task of overhauling some of our SQL-based systems. I've found many tables that don't have unique identifying numbers that really should have them. I've searched around and people keep mentioning the Identity field as being similar to Autonumber in Access. The only examples I could find involved setting up a new table... but I need to add (and populate) an identity column to an existing database table. Does anyone know the command for this?
Example... my table is called PACountyTown. It currently has 3 columns: County, Town, and Area. I wish to call the identity-ish field RecordID.
Thanks in advance!
Hello everyone,
I have a table X that has two columns (names have been changed to protect the guilty and innocent alike):
ID which is an identity column, and
Data which is a varchar.
I am trying to DTS data from a text file into this table. I want the identity column ID to auto-populate and each row of information from the file to be stored in the Data field.
I am creating the DTS package using the wizard in Enterprise Mgr. No matter what I try, I keep getting the following error:
Cannot insert the value NULL into column 'ID', table 'X'; column does not allow nulls. INSERT fails.
Any advice on what I need to do to get this working? It seems like such a simple thing and I'm getting very frustrated. :eek:
Thanks in advance.

Dear All,Suppose in the program a record is added to a table whoseprimary key is a identity field. If I really want to get the lastestvalue for that field after the insertion, is it the best way to useIDENT_CURRENT() to obtain this value?Thanks for your kind attentionYours faithfully,Benny

i am altering an int column to identity:

I am not able to create identity on a existing column using ALTER statement.
Can anybody help on this issue ?
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.

Does anybody knows how to set identity to column using ALTER Script.
Thanks in advance.

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,

Hi,
I have been trying to figure out how to use ALTER TABLE/ COLUMN to modify a column from an IDENTITY column to one which is not an IDENTITY column.
I would like to do this so that I could add another column (using ALTER) and set it as the IDENTITY column.
Any thoughts?
Your help is much appreciated,
-Scott
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.
I am in a scenario where my tables are refreshed every morning by a batch update. I have built a few views off of one table. To increase speed I would like to take all the rows from one of the view s and insert them into their own table. I know this can be done with some T-SQL but I'm a noob to it and don't know how to specifically do it.Any detailed help would be greatly appreciated. -Nate

I have list (in an input file) where each row is about 20K in size (so it can't be stored in a sql table). I want to convert the list into a table as shown below:
before:
---------------
pk1, c1, d1, c2, d2, c3, d3,......
pk2 c1,d1,c2,d2,c3,d3.....
where "pk" denotes a primary key and in a given row (c1,c2.c3,...) are all distinct. ("c" are columns names, "d" is the associated data)
after: (desired conversion)
---------------
pk1,c1,d1
pk1,c2,d2
pk1,c3,d3
...
pk2,c1,d1
pk2,c2,d2
pk2,c3,d3
....
I was planning to have SSIS pull in the "before" data, run a custom C# program in SSIS against it to massage the data to vertical (3-column format), then export the massaged data to a new text file. The new text file would later be imported into a sql table using SSIS.
