Restarting The Identity Column On Table Variable

Jun 2, 2006

In a cursor, I declare a table variable like so:

DECLARE @TempTable TABLE(RowID INT IDENTITY, valueID int)

I then insert into that table from another table.  The purpose is to get a list that looks like this after the insert:

RowID     valueID
1               34897
2               34522
3               94822

etc....

However, the next time through my loop (cursor) I want to restart my RowID identity property, because the next batch of valueID's should then again have a RowID starting from 1.

I tried

delete from @TempTable 
 DBCC CHECKIDENT(@TempTable , RESEED, 0)

but I get 'Must declare the variable @TempTable table' error.

Is there a way to destroy and recreate that @TempTable  variable?

SQL 2012 :: Seed Value Of Identity Columns Jumps / Gaps By 1000 After Restarting It?

Jan 9, 2015

We just switched from Sql server 2008R2 to Sql server 2012.I am facing one problem with identity Columns "When ever i restarts my sql server,the seed value for each identity column is increased by 1000 (For int identity column it is 1000 and for big int it is 10000).

"For Example if seed value of any table was 3 then after restarting sql server will be 1003 if i again restart sql server it will be 2003 and so on."

After searching on google i found that it is a new feature (don't know what is use of it) in sql server 2012 and having only two solution if you want old identity concept

1. Use sequence object -

a) I am using same database in sql server 2008 and 2012 both so can't use sequence in 2008.

b) if i go with sequence then need not change save procedure for each table,which is bulky task for us.

2. Use Trace Flag 272 (-T272)

I can go with this solution because there is need not do any changes in my application.Some one suggested me that add -T272 in startup parameter,after this sql server identity column will work normal as previous version.I did the same but it is not working.

I don't want to do any changes in my database structure.

how to use this -T272 or why it is not working.

I don't want to use this new identity feature how to suppress it. Why -T272 is not working.

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]

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,

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),

Identity Column In Temp Table

Jun 19, 2005

Hi,

I am trying to create a temp table with an identity column.  Here is the code that I am using...

SELECT UserId, IDENTITY(int, 1, 1) AS colId
INTO #User
FROM MyUserTable
WHERE UserId = 1

I am getting an error though.

Server: Msg 8108, Level 16, State 1, Line 9
Cannot add identity column, using the SELECT INTO statement, to table
'#User', which already has column 'UserId' that inherits the identity
property.

Is there any way to work around this? 

Thanks for your help.

INSERT Into Table With IDENTITY Column

Jul 31, 2001

I'm sure this is a common problem but I can't find any relevant info on this site

I have a table that I would like to insert values into. I want to take the values from a secondary table using a select statement.

e.g. a simplified version...


TABLE1
(
Id INTEGER IDENTITY,
UserName VARCHAR(50),
Description VARCHAR(50)
)

TABLE 2
(
UserName VARCHAR(50),
Description VARCHAR(50)
)

Runing the insert statement

INSERT Table1 (UserName, Description)
SELECT *
FROM TABLE2

results in the error
erver: Msg 515, Level 16, State 2, Line 2
Cannot insert the value NULL into column 'Id', table 'CDS_Live.dbo.Table1'; column does not allow nulls. INSERT fails.
The statement has been terminated.

I was under the impression that an identity column would be automatically inserted by SQL server. Now I know I could write a piece of anonymous Transact SQL which declares a cursor by selecting all rows from table 2 and inserting rows into table 1 on a row by row basis, but is there any way I could do the Insert with a single INSERT statement?

thanks

Importing Data In Table With Identity Column

Nov 13, 2000

Whenever I import (or even append from another table) data to a table that has an Identity column, I get an error: Cannot insert NULL values in Identity column.

Isn't the Idenity column supposed to incement automatically without me having to provide a value? Using INSERT provides an Identity value automatically, using import however doesn't.

How can I overcome this problem? (I now delete and recreate the Identity column - really BAD practice!)
Thank you.

Bulk Copying Into A Table W/identity Column

Jul 13, 1999

I'm having difficulty bulk-copying a data file, using a format file, into a SQLServer 6.5 table with an identity column.
The data file is tab-delimited, and does not include the identity column (I want it to be automatically generated).

When I execute the following:

bcp DB1.dbo.WORK_TABLE in WorkTable.txt -Usa -P -fWorkTable.fmt -SSERVERX'

I receive this message:

I've had no problems loading a similar table without the identity column.

Can't Insert Rows In Table With Identity Column

Dec 5, 2007

Hello, I have a problem. I am trying to pull data out of one system and bring it into a SQL Server database for faster retrieval. The original table does not have an identity column and has a composite primary key. The table I am inserting the data into matches the original table exactly except I have an Identity column that I need for the removal of duplicates. The task gets to the final commit and then fails telling me that it can't insert a NULL into an identity field. Why is it trying to insert a NULL, the field should be auto-populating. I did add the Identity field to the table after the SSIS package was already built, but I did go into the destination and fix the column mappings. For the Identity column I just selected the "skip" option or whatever it was. Why are the identities not being auto-inserted and why is SSIS throwing this error?

Can anyone help???

Thanks!

Not Able To Create An Identity Column For An Existing Database Table

Feb 1, 2008

I am working with a table in SQL server. I have a column that I want to designateas an identity column. I am not able to do this, because the field for "Identity Specification" is not editiable.
What I did was I went to sql server, right clicked and selected "Modify".The column properties dialog box/edit grid is then displayed with attributesthat I can modify.
There are two major nodes in this dialog box. One is named "General" and the otheris named "Table Designer". I expand the "Table Designer" node and then go to the node labeled "Identity Specification" It is here where I would like to edit thevalues.
The values that are listed for edit are listed below. BUT, the problem is thatI can place my cursor in those fields, but I am not able to change/edit them.Can anyone tell me what the problem is here? and how I can fix it?

Identity Column On Table And Ignore Duplicate On Index

Mar 27, 2007

Hello,

I have a table with an Identity Column set up. I also have an index on the table that is set to Ignore Duplicate. Identity starts at 1 and is incremented by 1.



So first 5 rows inserted get identity

1

2

3

4

5



If I insert rows that get ignored because of the index with Ignore Duplicate, it is ignored correctly. But, the next row to get inserted will have an identity value of 7.



So, even though the insert was ignored because of the index with Ignore Duplicate, the Identity column was incremented behind the scenes.



Is there any way to avoid this?



Thanks,

John
