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.
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...
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
In a t-sql 2012 sql update script listed below, it only works for a few records since the value of TST.dbo.LockCombination.seq only contains the value of 1 in most cases. Basically for every join listed below, there should be 5 records where each record has a distinct seq value of 1, 2, 3, 4, and 5. Thus my goal is to determine how to add the missing rows to the TST.dbo.LockCombination where there are no rows for seq values of between 2 to 5. I would like to know how to insert the missing rows and then do the following update statement. Thus can you show me the sql on how to add the rows for at least one of the missing sequence numbers?
UPDATE LKC SET LKC.combo = lockCombo2 FROM [LockerPopulation] A JOIN TST.dbo.School SCH ON A.schoolnumber = SCH.type JOIN TST.dbo.Locker LKR ON SCH.schoolID = LKR.schoolID AND A.lockerNumber = LKR.number
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).
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.
I also have a RESOURCES table of phrases (for translation purposes) similar to this:
res_id res_lang res_phrase AccessDenied en Access Denied
For some rows in the resources table I do not have all language codes present so am missing some translations for a given res_id.My question is what query can I use to determine the RESOURCE.RES_IDs for which I do not have a translation for.
For example I might have a de, en, cz translation for a phrase but not a pl phrase and I need to identofy those rows in order that I can obtain translations for the missing RESOURCE rows.
We are facing the following issue, several machines/users that are executing very often a command similar to :
INSERT INTO TableName (FieldOne,FieldTwo) VALUES ('ValueOne','ValueTwo'); SELECT SCOPE_IDENTITY() AS Table_ID;
Where TableName has a primary key defined as identity(1,1).and that Table_ID is being used as reference in others tables
These queries are executed using different dababase users and among several diffrent apps..The Problem is that we are detecting lost block of "Table_ID's" as the other tables shows the InsertedID as a reference, but the TableName table lacks of this ID record. In other words, the INSERT seems to work, the SCOPE_Identity returns an InsertedID, and the other tables are populated using this number. However, when we query the TableName table the mentioned record does not exist. We are profiling the server and we're sure that there are no DELETE statement on the TableName table. This seems to be happening when the are either deadlocks or blocked processes. Whenever the deadlocks and locks disappear/solved, everything works as expected.why the Scope_Identity returns the Inserted ID if the INSERT action had failed.
Greetings,If I use a "select into" to clone a table, all attributes are createdcorrectly, however, if I use the same statement across a linked server,my identity column loses its IDENTITY specification.Is this a known issue or basic functionality of using "select into"with linked servers?Kurt
In SQL Studio, I can go to the restore window and the click "verify backup media". This would check the restore plan listed in this window and check if some of the file are missed.Is there any way to reach this with TQSL? I know there is a "restore verify" command, but this will only verify one backup/file and not the complete restore path. I'm looking for a TSQL solution which is able to control that all necessary backup files are still present on the file System and not moved or deleted (e.g through cleanup task).
I 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.
I re-created a publication that was having problems and it gives this error when I start the snapshot agent from SQL Server Management Studio: I am stuck on how to resolve - any ideas?
"The publisher's identity range allocation entry could not be found in MSmerge_identity_range table. Transaction count after EXECUTE indicates that a commit or ROLLBACK TRANSACTION statement is missing. Previous Count = 1, current count = 2."
select * from MSmerge_identity_range returns 19 entries but I don't know how to fix.
I have tried deleting and re-creating but always get this error.
My other publications and subscriptions are working fine and I was able to create a new test publication that worked but can not get this one to work that worked fine up until today.
Why does M$ Query Analyzer display all numbers as positive, no matterwhether they are truly positive or negative ?I am having to cast each column to varchar to find out if there areany negative numbers being hidden from me :(I tried checking Tools/Options/Connections/Use Regional Settings bothon and off, stopping and restarting M$ Query Analyer in betwixt, butno improvement.Am I missing some other option somewhere ?
I have a table with a column ID of ContentID. The ID in that column is all NULLs. I need a way to change those nulls to a number. It does not matter what type of number it is as long as they are different. Can someone point me somewhere with a piece of T-SQL that I could use to do that. There are over 24000 rows so cursor change will not be very efficient.
I have an 'ID' column. I'm up to about ID number 40000, but not all are in use, so ID 4354 might not be in any row. I want a list of all numbers which aren't in use. I want to write something like this:
select [numbers from 0 to 40000] where <number> not in (select distinct id from mytable)
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 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,
barkingdog
P.S. Or should I pass the identity value back in a variable and not make it part of the data stream?
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
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. varun
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
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'.

I have a sales report that includes dollar amount, tonnage, and profit margin among other things. They are currently sorted by tonnage sold from highest to lowest. I'd like to be able to place a number in a column counting 1 up for tonnage ranking. I'd also like to get a number ranking for sales amount ranking along with profit margin ranking. The most tonnage sold might not have been the biggest sale nor had the highest profit margin.
Does this sound like something that can be done within SSRS?
I should ad I'm runing MDX queries against a cube so I can't use T-SQL for ranking.
