Hello,
I have an ID column which is an Identity column, and it counts from 1 upwards.
If I have 10 records, I have ID's number 1 to 10.
If I then add another record, it will give the ID number 11.
Imagine I then delete ID number 9
Is it possible to get the next record I create to take number 9 instead of 12 ?
I guess this is a fairly common topic but couldn't find the right words to find anything in a search.
What I'm getting at, is there any tsql functions or combination of commands for the following.
You have identity columns in your tables, if you set the a seed and autoincrement, I enter in rows 1 -10 and then I delete 4, 6, 7, 8.
My next new record uses 11. Is there any logic that allows you to check and reuse 4, 6, 7 & 8 described above? Not looking for something that consists of having to create an extra ID table for each table and handle configuring what the next available number is everytime an Insert or delete is called.
Thanks.
After moving our database between servers, one table had a hiccup in it's
identity column. The number jumped from 761 to 1886863475 on the next
insert. This is a production server and I didn't catch it until yesterday.
So I have several days worth of numbers in a central table. I can't clean
them out, but I wondered if I could do the following:
DBCC CHECKIDENT ('table_name', RESEED, 800)
I tested it on our development server and it doesn't seem to cause any
problems. I know that when we get to 1.8 billion on the identity column
again we'll get an error, but I'm willing to risk it.
A few questions. 1) Am I insane for trying this? 2) Has anyone else ran into
a similar problem and what did you do to fix it? 3) If I do this, is there
anything in particular to watch out for? 4) What caused the jump in the
first place?
My other option is to change the datatype from int to decimal(19) or
something along those lines. This will upset our programmers and I'll have
to change all my foreign keys (not a big deal, just a pain).
Any input at all here would be appreciated.
Thanks,
Grant
I have a table in which there is a column of type identity(1,1),in the same table i have bulk data, and i have deleted a row from my table, so now i want to reuse that same Id again, how to do that.
View 3 Replies View RelatedI have a report with a column which contains either a string such as "N/A" or a number such as 12. A user exports the report to Excel. In Excel the numbers are formatted as text.
I already tried to set the value as CDbl which returns error for the cells containing a string.
The requirement is to export the column to Excel with the numbers formatted as numbers and the strings such as "N/A' in the same column as string.
Any suggestions?
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.

Hi All
I am using SQL 2000 on win 2003 server and I have been using the query analyzer and a stored procedure to add records to a particular table.
For some reason the ID column which is an identity column and is seeded to increment by 1, skips numbers every once in a while. I haven't used any deletes and there have been no errors when loading the info.
Has this happened to anyone else? Where do I start looking for possible causes
Thanks

I have inherited a system which uses Identity numbers for primary key fields, but also displays them for the user to see. The user has noticed missing numbers in the sequence, sometimes just a few numbers and sometimes as many as 1000 numbers missing.
As far as I can tell the few numbers missing could possibly be explained by users deleting records or the number being generated on a save, but the save then failing. But I can't explain the huge jump of 1000.
I can find no reference to the RESEED in the code...
Is there a way to check for missing identity numbers in a Primary Key column? I have some databases that are not fully normalized and want to check on tables that might have had some records deleted. Thank you.
when i alter non identity column to identity column using this Query alter table testid alter column test int identity(1,1) then i got this error message Msg 156, Level 15, State 1, Line 3 Incorrect syntax near the keyword 'identity'.
View 2 Replies View RelatedI 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
View 2 Replies View RelatedI'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
I'm trying to find a decent way of multiplying a set of numbers in a column without using a cursor in T-SQL.
There is no 'Product' aggregate function that I'm aware of in SQL 7 or 2000. The workaround I'm currently using is this :
SELECT EXP(SUM(LOG(ColumnName))) FROM tblName
This works fine, except when negative numbers are introduced. The LOG function does not allow negative numbers and therefore returns a domain error and the negative number is eliminated from the aggregate.
I could use a cursor to do the multiplication, however, this is proving too slow for the bulk calculations involved.
If anyone has any ideas or suggestions, then that would be much appreciated.
thanks....Tom

HI all;
I have a simple question to ask; I need to create a column with the data from my DOB column (which has the smalldatetime type attached to it). I know how to do that but I am not too sure how to convert the data from that column int normal character for example when I copy it into my newly created column and change the type to varchar I get this jan 16 1979 from this date 1979/01/16. But I actually want the data to look like this 19790116, so in effect I just want to take out the slashes.
Any help would be highly appreciated, thanks all.

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;
I'm trying to create a column of numbers that increment by one.
I'm not able to use a #temptable in the application I'm using so I cannot use IDENTITY(int,1,1).
I want to add an Id column to this query:
Select distinct sd.name,ic.TABLE_SCHEMA,ic.TABLE_NAME from sys.databases sd

How can I accomplish this without creating a temp table? I would just alter the table and insert the numbers but there are 2000 rows.

Hello,
One more question about this Custom Calendar table I'm creating. I have a column called "IsWorkdays" which indicates if the day represented by a row is a workday or not. For our purposes, I also need to create a row that accumulates those numbers by month. So, if it is the 3rd workday of the month, this column would have a 3. This is beyond my current T-SQL ability. Does anyone know how to do this?
Thanks a lot,

I'm grappling with this issue which I thought was basic VB programming; I'm trying to insert a random number (between 100 and 999) into a SQL table column (=Status_ID).
