View 5 RepliesI know that TRUNCATE TABLE can be used to reset the identity counter, but it can't be used on a table referenced by a foreign key. Anybody knows how to do that? Thanks.

I have a table with Identity column starting from value 1 and autoincrementing 1 for every new value. I inserted (5) rows and then deleted these rows. But, when i insert a new row, it was taking the last identity value(5)and inserting the rows with next identity value i.e., 6 for this column. I dont want that. Everytime, I delete and insert rows in to this table.I wanted the rows to start with 1 for this column.
Any help on this is highly appreciated.
Thanks!

Changing the seed and increment values on the identity column
- CREATE TABLE MyCustomers (CustID INTEGER IDENTITY (100,1) PRIMARY KEY, CompanyName NvarChar (50))
- INSERT INTO MyCustomers (CompanyName) VALUES ('A. Datum Corporation')
- ALTER TABLE MyCustomers ALTER COLUMN CustId IDENTITY (200, 2)
When i excute the Alter command, following error comes:"Incorrect syntax near the keyword 'IDENTITY'."I've picked the example from SQL SERVER 2005 books online.Please let me know if we can change the seed value on the identity column from a sql command.

I am in the middle of taking course 2073B €“ Programming a Microsoft SQL Server 2000 Database. I noticed that in Module9: Implementing User-Defined Functions exercise 2, page 25; step 2 is not returning the correct answer.
Select employeeid,name,title,mgremployeeid from dbo.fn_findreports(2)
It returns manager id for both 2 and 5 and I think it should just return the results only for manager id 2. The query results for step 1 is correct but not for step 2.
Somewhere in the code I think it should compare the inemployeeid with the previous inemployeeid, and then add a counter. If the two inemployeeid are not the same then reset the counter. Then maybe add an if statement or a case statement. Can you help with the logic? Thanks!
Here is the code of the function in the book:
/*
** fn_FindReports.sql
**
** This multi-statement table-valued user-defined
** function takes an EmplyeeID number as its parameter
** and provides information about all employees who
** report to that person.
*/
USE ClassNorthwind
GO
/*
** As a multi-statement table-valued user-defined
** function it starts with the function name,
** input parameter definition and defines the output
** table.
*/
CREATE FUNCTION fn_FindReports (@InEmployeeID char(5))
RETURNS @reports TABLE
(EmployeeID char(5) PRIMARY KEY,
Name nvarchar(40) NOT NULL,
Title nvarchar(30),
MgrEmployeeID int,
processed tinyint default 0)

WHILE @RowsAdded > 0
BEGIN
-- Mark all employee records whose direct reports are going to be
-- found in this iteration
UPDATE @reports
SET processed = 1
WHERE processed = 0
-- Insert employees who report to employees marked 1
INSERT @reports
SELECT e.EmployeeID, Name = FirstName + ' ' + LastName , e.Title, e.ReportsTo, 0
FROM employees e, @reports r
WHERE e.ReportsTo = r.EmployeeID
AND r.processed = 1
SET @RowsAdded = @@rowcount
-- Mark all employee records whose direct reports have been
-- found in this iteration
UPDATE @reports
SET processed = 2

I have a table where I delete all the records, then reload. can I reset the identity to (1,1) Is there a SQL command for that?
-smcirish
In my application , DB has a large table. I write a small program to clear the table whenever the size of table is over 50 MB. At that time , I want to reset identity as 1. How can I do that?
Currently , my program delete old table and generate a new one with the same schema when the table is too large.But this is kind of ugly.
Can a column of Identity type reset after it reaches its maximum value?

I want to delete all the table rows, restore de seed, and restore a
backup made on a XML (using SET IDENTITY_INSERT Table ON)
I cant drop the table due to acount restricctions.

Obviously to delete all records from DB table is simple, however, I would like to make my whole Live DB pretty much empty. I've copied all my data from my test DB over to my live DB (didn't mean to but I did). I would like to remove all the data and the identity values, resetting them back at their original values. Is there a simple way or do I have to do it the hard way. That being going in and removing Identity, saving and then placing identity back on the DB Table.

Reset the Identity IncrementHello:I have a table with a bigint type column (field) that has an identity seedof 1 and an identity increment of 1. The column is the primary key for thetable.After I backup and clean out the database (delete all of the data in the DB)I need to have the column with the identiy seed/increment value reset to 1automatically. (start counting at 1 again). How does one do that, becauseas it is now, the DB keeps increasing the value of the column from where itleft off, regardless of the fact that I deleted all of the data in thetable.The DB is MS SQL Server 2000.Thanks and appreciate any help.Ryan Kennedy
View 2 Replies View RelatedI have a test database that is being moved to the production server. Currently in one of the tables I have an identity seed for each record.

I have a remote DB I am wokring with at present. The DBA has provided me with a non owner LOGIN so I can't copy tables from the live to the staged DB as objects I can only copy tables and data.
The PKEY and IDENTITY COLUMNS get reset to just regular columns on each table. I can restore the PKEY constraint and have come across the DBCC CHECKIDENT to get the new ident value. I just can't figure out how to set a column to be an identity. The ALTER TABLE command isn't having any of it.
I am obviously missing the right bit on Books online
any suggestions?
many thanks

I have a demo database in SqlCE that I am getting ready to deploy. I deleted a bunch of test records and now want to reset the identity columns. The compact method runs fine, but the identity columns are not being reset? So when I add a new record, the returned identity value is over 1,000 even though the highest value is only 50.
Any help is greatly appreciated!

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.

I posted a thread in the Getting Started forum about how to make a counter for maximum tickets : http://forums.asp.net/t/1215258.aspx
but maybe this is a more appropriate forum for this subject.
In a school project, we are making a website for a fictional concert/festival (using Visual Studio 2005, C#). On that site users can register and order tickets.
We have access to an SQL-database, by the way, where we can create tables etc.
We want the maximum amount of tickets to be 10000 per day. The festival is supposed to last from friday to sunday.
What would be the best way to do this programatically? The counter should maybe be in an own database table?

View 6 Replies View RelatedI have a table ComponentPeriod. In it we have the combination of a component (e.g. A,B,C ) and a period (2014 Q1, 2014 Q2, 2014 January etc)I want the periods to be in descending order (2015 Q4, 2015 Dec, 2015 Nov, 2015 Oct, 2015 Q3 ... etc) and so I need to create a sequential number series to allow this to happen (as we can only order in the client tools by a single column - and so I guess the technique I'm looking for is used a lot to produce these types of "order by" columns)
I have done this in the past using
Period_Sequence =
calculate
(countrows(Period)
,filter
(Period
, Period[Start_Date] <= earlier(Period[Start_Date])
&& Period[Duration_String] = earlier(Period[Duration_String])
)
)
Which was fine when I was referring to a table where Periods where distinct directly but now I have denormalised this for ComponentPeriod so I need something a little more sophisticated Whats the best way to get a sequence with perhaps some partitions in across a subset of distinct columns (I guess from SUMMARIZE or similar)
E.g. I want
Period_Name, Type, Sequence
2015 Q4, Quarter, 1
2015 Dec, Month, 2
2015 Nov, Month, 3
2015 Oct, Month, 4
2015 Q3, Quarter, 5
2015 Sep, Month, 6
etc
even though there may be multiple records in ComponentPeriod that have the period 2015 Q4, but I want them all to have the value Sequence value of 1? I've got as far as:
Period_Sequence Desc =
calculate
(countrows(summarize(ComponentPeriod, ComponentPeriod[Period_End_Date]))
,filter
( ComponentPeriod
, ComponentPeriod[Period_End_Date] >= earlier(ComponentPeriod[Period_End_Date])
)
)
But this doesn't distinguish between the different types. I need an equivalent of the t-sql -
row_number() over (order by Period_End_Date desc, case when 'P3M' then 1 when 'P1M' then 2 end asc
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 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
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?
