How do i Find all Columns that have Identity Property in a database. That is i will like to know all columns in a database that are identity columns.
I am using SQL Server 2005. Thanks
Is there a query I can write against an INFORMATION_SCHEMA or against the system tables to determine if a column is an identity column?
View 8 Replies View RelatedHello friends,
I am using sql server 2005. In some tables to create the column Autoincrement I had set the 'Idetity Specification' property to 'Yes'. I want to know that how can we do it through sql scripts i.e. by writing query.
Please let me know

Hi,
I have a VB script that I am using to run various DTS procedures. One of these involves using DataPumpTransformCopy to copy data from one table to another. The destination table has an Identity field that I would like to disable for the duration of the Transform.
I have tried opening a Command Object and running the "SET IDENTITY_INSERT" function beofre and after the Transform but although it doesn't produce any errors it doesn't seem to actually do anything...
I figure I need to try using the ALTER TABLE to disable the IDENTITY but I can't find an example of how to do this anywhere.. can anyone help me out here?
Many Thanks,

How can i remove identity property of a particular table with sql command.
Thanks.
I assume that the identity property is stored within a given database, so there should be no need to run dbcc checkident after restoring from a backup. Is this a correct assumption?

But after export tables that Property is not True How I can change it True With Query Analyzer????????/
Is there a way to remove the Identity property of a column in SQL Server 2000?
The statement:
<code>
ALTER TABLE <table name> ALTER COLUMN <column name> DROP IDENTITY

Hi,
Please let me know if it is possible to replicate a table with identity property defined in it. Both the publisher and subscriber tables have identity property defined. Which option should be used while setting up transactional replication to allow the identity values at the publisher pushed to the subscriber, which also has identity property defined? Not for replication option with the identity property also fails. Whichever option I choose I get the error, 'An explicit value for the identity column in table 'jobs_id_nfr' can only be specified when a column list is used and IDENTITY_INSERT is ON.' This works only if the identity property is not defined at the subscriber. But, I need to have the identity property defined at the subscriber also because the subscriber should be an exact copy of production.
Thanks in advance,

Has anybody ever tried to do this. I can't figure it out. All I want to do is take an existing table that already has values in the column that I want to change and add the identity property to yes and set the identity seed and increment to a specific number. I know you can do it in the CREATE TABLE statement but is there a way to use the ALTER TABLE command?

Have anyone faced the timeout issue when setting a IDENTITY property of a column to NO.
Is there any way to resolve it ?
Note : The table on which I'm doing the operation is having approx 50 million records.
Thanks,
Hariarul.
I get the below error :
'TrnBillDetail' table
- Unable to modify table.
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

Is there any way to remove IDENTITY property on particular table? I tried removing IDENTITY property using Manangement studio, but this operation behind the scene use migration concept that is by creating tmp table and then populating with data; droping the orginal and renaming the tmp back to original.
Second, i want some kind of generic solution using certain system table like aya.sysobjects, sys.identitycolumn etc such a way that i should be able to remove the idenity property from all of the table accross a database.

Hi,
I am planning to use transacational replication (instead of merge replication) on my SQL server 2000. My application is already live and is being used by real users.
How can I ensure that replicated data on different server would have exact same values of identity columns and date columns (where every I set default date to getdate())?
It is very important for me to have a mirror image of data (without using clustering servers).
Any help would be appreciated.
Thanks,

Hi All,
I developed a report with some values in textboxes. I want the output not to wrap around to the next line but to be truncated if it is more that the size of the textbox. Is there any setting that i can do b/c values are going to the second line when their size is more like printing name and last name will cause last name to go to the second line ?
Thank you in advance.
Hi,
Is there an easy way (a sql script) to drop the "MS_Description" of all tables and all columns in my database?

Just to confirm, do identity columns and XML columns work OK with database mirroring ? That is, all data types are supported with mirroring, and identities aren't an issue ?
Transactional replication with identity columns was a right pain in the **** in SQL 2000. I'm assuming that mirroring doesn't have these issues, but want to be sure.
This ain't working
SELECT T.TABLE_NAME,C.COLUMN_NAME
FROM INFORMATION_SCHEMA.TABLES T
JOIN INFORMATION_SCHEMA.COLUMNS C
ON T.TABLE_NAME = C.TABLE_NAME
WHERE OBJECTPROPERTY(OBJECT_ID(T.TABLE_NAME),
'TableHasIdentity') = 0
AND T.TABLE_TYPE = 'BASE TABLE'
AND OBJECTPROPERTY(OBJECT_ID(C.COLUMN_NAME),'IsPrimary Key') = 1
ORDER BY T.TABLE_NAME,C.COLUMN_NAME
This is giving me bogus results...
SELECT * FROM INFORMATION_SCHEMA.COLUMNS
WHERE OBJECTPROPERTY(OBJECT_ID(COLUMN_NAME),'IsPrimaryKe y') = 1
I have PK's all over the place. What gives? Too many cocktails with lunch?
How do i find all the tables that have an Identity Column as a primary key in a database. Thanks.
View 8 Replies View RelatedCan anyone describe how SQLServer calculates identity
columns? Does it use some internal counter when generating the next identity,
or something a little more mundane such as gets the highest existing identity
value at the point of the insertion and increments it by the IDENT_INCR value
of the identity column?I’m not worrying about reliability or gaps in values, but i
am wondering if it would be less efficient for me to manually manage the
identity/primary key in the form of a counter in another table used to generate
the new identity, or simply let the DB do it for me. I dont mind if there are
gaps in the sequence etc. so would it be less efficient for me to calculate the
field than SQLServer itself? Basically, is the overhead to the DB of me doing
it greater than the overhead of the app doing it...Thanks
First off I am NOT a DBA.
I have a question about IDENTITY columns. I am working for a client that has an entire employee database that uses IDENTITY columns without any Primary keys defined. I have never seen this done. Is it ok or should I recommend that it be changed to use Primary keys?
The DBA that built the database is no longer with the company and the client has no DBA. Where can I get some information on how to use IDENTITY columns? I did not get much from the help file.
TIA
Nate
Where do I find the seed and increment values of the identity column in database.
If possile can u suggest query for that Pl.
Thanx in advance

I have been using the following query to identify the IDENTITY columnsin a given table. (The query is inside an application.)select column_namefrom information_schema.columnswhere table_schema = 'user_a' andtable_name = 'tab_a' andcolumnproperty(object_id(table_name), column_name, 'IsIdentity') = 1This works. When "user_a" performs the query, everything is OK.Now, another user wanted to use the same application. So, "user_b"clicks on a button, and the exact same query as above is run. (Nosubstitutions are made; user_b is trying to see the identity column in[user_a].[tab_a]). However, the query returns null, instead of theidentity column name. User_b can read the table and select from itjust fine.Why am I getting two different results against the same query? Do Ineed to rewrite the query to go against different information schemaviews?
View 5 Replies View RelatedI'm seeing some weird behavior regarding identity columns in MSSQL 2000.In a specific client database we have this table:
ID Name SecLevDG Flags ----------- ----------------- ----------- ----------- 1029528 xxx 0 01029529 xxx 0 01049676 xxx 0 0
While upgrading this database to a later version of our product, some schema changes are necessary. For this particular table, the changes are
alter table Authority drop constraint apkAuthorityId
alter table Authority drop column SecLevDg
alter table Authority add new_id integer identity
This code has worked perfectly for years, and even in this particular database, there are no error messages. However, the result isn't quite the expected:
ID Name Flags new_id ----------- ---------------- ----------- ----------- 1029528 xxx 0 167772201029529 xxx 0 167772201049676 xxx 0 16777220
Notice that the new column did NOT get unique values 1, 2, 3, etc... In other tests I manage to get different values, but still not the expected ones. Is this a bug in MSSQL 2000?
DBCC CHECKIDENT returns:
Checking identity information: current identity value '1', current column value '1'.
DBCC CHECKDB returns no errors before running the above statement. Afterwards it returns this (only relevant messages included):

I have an app that has multiple users inserting and updating from a couple key tables using SQL Server 2005.
In my previous SQL coding life, I was able to make use of sequence.NextVal to find and lock the next available sequence value for a table. Currently I am in the SQL Server 2005 world and cannot do this. I have found all sorts of help for Ident_currentand Identity columns, but nothing on how to accomplish the same as a NextVal did. I can add one to the Ident_Curr but I think I run the risk of that value being used by another user before the current user can get his update in. Is that correct? Is there a way to accomplish what I am trying to do?
Basically what I need to do is when a user inserts a record in table "Loads" I need to insert behind the scenes to table "Comments" with the ID of the row created in the "Loads" table.
Thank you in advance,
Garth
Hello there,
I am using sql 2000 dts package to migrate a databse to SQL Server 2005, everything works except for identity columns, SQL Server reorder the columns, and this breaks the referential integrity. Is there a way to stop that? Your help is appreciated.
I use the identity = yes for my unique columns in most of my tables that need it. I am trying to decide if I should change identity = no, and instead manually update my unique number column myself by adding one when I insert new rows.
The reason I want to do this is for maintainabilty and ease of transfering data for backup to other sql servers. I always have trouble keeping the identity numbers to stay the same as they are in the original database because when they are transfered to a db that has identity = yes, the numbers get rearranged.
It will also make it easier to transfer data from original db to another sql server db and use the data right away without having to configure the destination db to disable identity and then enable it, etc.
Any pro's con's appreciated,
Dan

I have a production database with about half the tables using
IDENTITY columns for PRIMARY KEYS. This system is configured as both
a Publisher and a Distributor. We are using Transactional Replication
without updates. The SQL Server Agent runs every hour to pick up any
changes and replicate them to the Subscriber (another SQL Server
machine configured as our failover server).
Both servers are running SQL Server 7.0 (original, no service packs)
under Windows NT 4.0 (SP4).
The failover server (the replication Subscriber) will only be used if
the primary server goes down. And hopefully, only for a short time
before the primary server comes back online. During the time that the
failover is actually being used, the application will not make any
changes to the database.
The IDENTITY values that are replicated need to stay with their
original values. The replication process CANNOT assign new values to
these columns when there are inserted into the database on the
Publisher (i.e. failover server)
My question is: According to the documention, I can add 'NOT FOR
REPLICATION' to the IDENTITY columns and the values will be
preserved. But a collegue of mine says that resets the IDENTITY
sequence on the subscriber and the 2nd time a row gets inserted on
the Publisher, the values get messed up. On his system, he calls a
stored procedure for the tables with IDENTITY columns, and in the
stored procedure, he executes a 'SET IDENTITY_INSERT OFF', then
INSERTS the row, then 'SET IDENTITY_INSERT ON'. He claims that this
approach solved his issues with IDENTITY columns.
Who is right? Do I have to create a stored procedure for replication
for every table with an IDENTITY column, or can I just add 'NOT FOR
REPLICATION' and SQL Server will handle the rest?
NOTE: Upgrading to SQL Server 2000 is NOT an option right now.
Although, if a Service Pack for 7 fixes this, that might be an option.
Thanks in advance for any help you can shed on this issue.
Dave
