Dropping The Identity Property
Dec 19, 2001
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,
Seoras

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
ORDER BY pk.table_name, c.column_name

Hi,
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.
Thank you!

Hi,
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).
Thanks a bunch
Moshe

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?

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
</code>
returns a syntax error.
Thank you,

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,
Praveena

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?

Hi all,
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.

I am having problems exporting data into a flat file using specific code page. My application has a variable "User::CodePage" that stores code page value (936, 950, 1252, etc) based on the data source. This variable is assigned to the CodePage property of desitnation file connection using Property expression.
But, when I execute the package, the CodePage property of the Destination file connection defaults to the initial value that was set for "User:CodePage" variable in design mode. I checked the value within the variable during runtime and it changes correctly for each data source. But, the property of the destinatin file connection doesn't change and results in an error.
[Flat File Destination [473]] Error: Data conversion failed. The data conversion for column "Column01" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".
[DTS.Pipeline] Error: The ProcessInput method on component "Flat File Destination" (473) failed with error code 0xC02020A0. The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running.
If I manually update the variable with correct code page and re-run the ETL, everything works fine. Just that it doesn't work during run-time mode.
Can someone please help me resolve this.
Thanks much.

Hi,
I developed a simple custom control flow component which has several read/write properties and one readonly property (lets call it ROP) whichs Get method simple returns the value of a private variable (VAR as string). In the Execute method the VAR has a value assigened. When I put the value of ROP or VAR into MsgBox I can see the correct value. However when I execute the component I can not see the value of the ROP in the property window. I see the property but its value is empty string. For example when I put a breakpoint to postexecute or check the property before click OK in a MsgBox I would expect that the property value would be updated in SSIS as well. Is there a way how to display correct values of custom tasks properties in property window?
Thanks for any hints.

Untill recently I had a smooth running SSIS package,but suddenly it throws error syaing
"OnError,,,,,,,The result of the expression
"@[User:trTextFileImpDirectory] +"SomeTextStringHere"+ @[User:trANTTextFileName] +(DT_STR,30,1252) @[User:taging_Date_Key]+ "SomeTextStringHere"
" on property "ConnectionString" cannot be written to the property. The expression was evaluated, but cannot be set on the property."
I have child SSIS package running under a parent package (through execute package task)
I have few flat file connection managers in child package for text file import , in which I am building text file path dynamically at run time by assigning an expression in connection string property of connection manager.
The Expression is as follows
"@[User:trTextFileImpDirectory] +"SomeTextStringHere."+ @[User:trANTTextFileName] +(DT_STR,30,1252) @[User:taging_Date_Key]+ +"SomeTextStringHere"
Where @[User:trTextFileImpDirectory] is a variable which contains path of directory containg text
files.Value in this variable is assigned at runtime from parent package's variable,which in turns fetch
value from a configuration file on local server.
With my current configuration this path has been configured to some other server's directory over network ( I.e my package picks text files from some other servers folder over network)
While
"Some string here"+ @[User:trANTTextFileName]" part of file name string.
(DT_STR,30,1252) @[User:taging_Date_Key] Contain the date of processing ,value in this variable is also picked up at run time from parent package variable.
1) So can someone give me some insight into possible reason of failures.
2) Is it possible that problem arises if directory (from which I m picking text files) is assigned password or is there exist some problem in accessing forlders over network ?
3) Or there can be some problem in package configuration at design time( I.e where I m assigning value in variable from parent package vriables)?

Hello,
I have a group I'll call G4.
The header table row for G4 contains 3 textboxes containing the sums of the contents within G4. The header table row for G4 is visible while it's contents, including the G4 footer table row, is kept invisible until the report user drills down into the group.
When the report user drills down into G4 the footer table row becomes visible and the sums of the contents of the group are displayed for a second time.
At this point I want the sums in the header to be set to invisible when the sums in the footer are made visible by the drilldown.
When I try to reference the hidden property of textbox66 in the G4 footer in order to set the hidden property of header textbox57 in the G4 header I get to this point...
=IIF(reportitems!textbox66.
When it fails to give me an option of choosing the .Hidden property and instead only gives me a .Value.
If I complete the IIF statement manually so that it spells out .....
=IIF(ReportItems!Textbox66.Hidden = False, True, False)
...the report chokes on it.
So my question is, how do I reference the hidden property of one or more textboxes in a group to use as condition checks to set the hidden property of another textbox in that same group?
Thank you for any help you can provide. We are only now beginning to implement reporting services and I have not yet had the chance to research this in greater detail for lack of time.

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?
TIA,
Barkingdog

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?

Is there a way we can prevent a object owner from dropping his tables. Example:
There is a user called 'tom' who is given create table permissions, 'tom' creates the table completes his dev and then the table is moved into production where 'tom' is still the owner. However, in production, 'tom' does not have the create table privs. Because 'tom' is the owner of the table, he is still able to drop the table in production. This is what I am trying to avoid. I would like to retain 'tom' as the owner and want to take away his create/drop privs.
