I'm creating a VB program that does some DB manipulations.
I need a programmatic to drop the Identity property (not the column data) so that the field will be just an Integer with the old data...
It seems like the only way is the EM way (creating a temp table with no identity on the column, copying the data into it, deleting the old table, and re-naming the temp...)
I'm looking for a more inovative way, or possibly a way to automate the process (so I'll be able to do this for all tables in a database in a modular way).
How do i drop/remove the identity property for an existing column in all Tables where the Identity column is a primary key. The Script below was used to find all the tables that have an Identity Column as a primary key in a database. Now i want to remove the identity property from the Identity Columns that have a primary key in the database.
select pk.table_name, c.column_name,
from information_schema.table_constraints pk
INNER JOIN information_schema.key_column_usage c ON c.TABLE_NAME = pk.TABLE_NAME
and c.constraint_name = pk.constraint_name
where constraint_type = 'PRIMARY KEY'
and COLUMNPROPERTY(object_id(pk.table_name), column_name, 'IsIdentity') = 1
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?
Is there a way to drop a column identity using TSQL?
Also, does this code look correct?
declare @max1 int declare @max2 int select @max1 = max(acid) from cms_2a alter table cms_3a add cwid int identity(@max1, 1) <------ Error select @max2 = max(cwid) from cms_3a alter table cms_4a add cwtid int identity(@max2, 1) <------ Error
I do not have identities on tables cms_3a and cms_4a, but I do have an identity on cms_2a.
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
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 table with multiple column and has millions of rows in it(say about 50 millions ) and its in production. What is the best way of dropping the a column from the table without impacting the systems performance. Remeber this table will be used some application to get some data out of it.
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 am trying to drop the "allow nulls" characteristics on an existing table column. I know that there are not Nulls currently in this column, nor will there ever be. How do I get rid of that "allow nulls" checkmark on an existing table structure? Thanks, Craig.
I have a query that produces unique rows. However, some of the unique rows have the column called testname that has the same test listed more than once. All I want to do is drop the older testname and keep the testdate column.
Select Distinct TestID, TestDate, TestName
From third.test
I want to keep testdate in the query....guessing I need to put in to a temp table then drop the oldest one somehow by doing a subquery using Select Max....
Hello,A while back I dropped a text column from a SQL Server 7 databaseroughly 3GB in size. I expected the size of the database to decreaseby around 1GB, but no change occurred. After searching usenet, Idiscovered that SQL Server 7 has no way of reclaiming that space, butthat there is some command that can be run in SQL Server 2000 thatwill reclaim it.I have since migrated this database to SQL Server 2000, and am nowtrying to figure out what that command is, but cannot locate anyusenet posts about it... also tried searching books online, but can'tfind anything that way either.Does anyone know what I should run?Thanks,Tom
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
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.
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;
Hello; My Memebership table has Guid column as Primary key. But I would like to add Auto numbering Identity column to this table. Is this idea OK or it will bring some problems? Thank you in advance for your help
Hi(SQL Server 2000)I have an existing table (t) with a column that is NOT an identity column(t.ID), but it has manually inserted "row numbers". I want to make thiscolumn become an identity column. This column is a key field to othertables, so I want to keep the row numbers that are allready inserted.From the Query Analyzer, how do I do this?Thanks in advance!Regards,Gunnar VøyenliEDB-konsulent asNORWAY

Having an identity column in target table, how do I use SQL 7 DTS ?
In Import wizard, I chose 'ignore' in source, checked Enable Indenity Insert - DTS failed with a msg like - a column cannot have NULL...
In DTS package, had Fast load and Enable Indenity checked - no luck !
Unchecked Enable identity, do luck.
What would be the standard procs for this since this sounds like a very common senario. What I am expecting is to insert from source and SQL would take care identity column automatically. Appreciate your help very much !
I want to know how to reset the identiy column when i delete a row from the existing table.
Example:
I have a table a with id (identity incr value 1) and name
I have 10 records inserted into it.,which would be from 1...thru...10 i delete a record say 5 then i have 1,2,3,4,6,7,8,9,10, now i want them to be rearranged to systamatic order like 1,2,3,4,5,6,7,8,9 how can i do this.
I have a table that has a field that will not accept null values. I was trying to create a new table with a new field that would accept null values. I would then drop the original table and rename the new table. The problem is my key field has the Identity column (Autonumber) turned on. This allows the recordID to be automatically generated. Is there anyway to bypass the Identity Column feature and still keep it there future records? I already tried the "with Nocheck Clause" but does not work.
How does one bcp data INTO a MS SQL Server table that includes an IDENTITY column from a text file that does NOT include a value for the IDENTITY column? Surely, this must be a common process?
Kudos to y'all! On most of my tables, I'm using a column of data type numeric and properties set as Identity with no replication. Now I know that it can handle only a length of 9 and obviously not nullable. Now by length of 9, does it mean in bytes or literal digits. If it is, then that would mean that it would reach only up to 999,999,999. What happens then if it reaches that digit?
How do you insert into a table that has an identity column aset of rows with predefined values for the identity column. I have tried to Set Identity_insert off and then insert but it didnt work. any ideas?
