Is There Any Way To Remove IDENTITY Property On Table?
Aug 1, 2007
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.

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, I want to know how to remove identify property from a column without recreating the whole table...
When I do it in Enterprise Manager, it actually drop and recreate the table
in background. I just like to know if there is other way without recreating the tables. Thanks!

Im working through the MS example of "removeDuplicates". I cant seem to figure out how to add custom property for input column.
I added the helper method:
private static void AddIsKeyCustomPropertyToInput(IDTSInput90 input, object value)
{
IDTSCustomProperty90 isKey = input.CustomPropertyCollection.New();
isKey.Name = "IsKey";
isKey.Value = value;
}
I call it from:
public override void ProvideComponentProperties()
{
//...
AddIsKeyCustomPropertyToInput(input, false);
//...
}
public override void ReinitializeMetaData()
{
IDTSInput90 input = ComponentMetaData.InputCollection[0];
if (input.CustomPropertyCollection.Count == 0)
{
AddIsKeyCustomPropertyToInput(input, false);
}
// ...
}
However when I deployed it and added the component to SSIS package - I cant see the Custom Column "IsKey" in the input column properties window.
What am I missing - please help

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

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

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.

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,
I have been trying to figure out how to use ALTER TABLE/ COLUMN to modify a column from an IDENTITY column to one which is not an IDENTITY column.
I would like to do this so that I could add another column (using ALTER) and set it as the IDENTITY column.
Any thoughts?
Your help is much appreciated,

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,

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 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)?

I want to store data warehouse source tables and files in an Archive schema and then delete / drop them after a specified period of time.
Is there a table property that I can set (can't find one) or some other mechanism so that I can easily identify these tables with a script.
If there is no such property or feature within the database engine I will define a metadata table and record it there, but a property or similar that I can set at archive time would be very handy.

Hi,
I am developing a report that should be localized dynamically. The report will have both arabic and western users. Therefore I need to use the direction property of some single text boxes, which works fine. But when setting the direction property to RTL for a table it has no affect!
You would assume that the whole tables content should be "reversed" and also the text in the table went from right to left. But no.
When viewing the report in IE and right clicked and click "View Source" you can see that the table do not have a direction style set, even though I set the property on the table in design mode.
I am going crazy about this issue! Could this be a MS bug?
I really need some help here...
PS. I have tried numerous of combinations of the different International properties to get the direction property to work - with no luck.

I need a SSIS Package that compares the two tables and removes the rows in the first table with keys that do not exist in the second table. For example....
I have a table of returns based on returnID. In another table I have returnErrors that are based on returnID as well. I want a package that will uses my returns table as a source and compares that dataset to the dataset of the returnError and remove or spilt the data so that my remaining dataset only has returns that have returnErrors. I can do this in T-SQL, but I am looking for a SSIS solution that uses the conditional split transformation or some other transformation(s) combinations.

I am putting together an invoice for my company. I have a text box describing each section of the invoice, followed by a table to list out the charges. I am using multiple tables based on what type of charge the client is receiving.
I would like to hide each section if there are no items purchased of that type. I can do this with the table using the expression "=CountRows() < 1", but I do not know how to refer to that table (call it Tablix1 for the sake of discussion) for the text box. I've tried using a ReportItems function as my basis, without success.

Hi
Can we have truncate table with in a transaction using SSIS package.
here is the scenario.
OledbDestinationConnection 's "retainsameconnection" property has been set to true.
I have added a Execute SQL Query task to "begin transaction".
second Execute SQL Query task to truncate a table. say table "A" . truncate table a(table does not exists in the database).
third to rollback a transactions if the second task fails.
Now when I am running my package, I am getting an error saying
The Rollback transaction has no corresponding "Begin transaction".
However if , I truncate a correct table , which exists in database, then all steps gets executed successfully.
And the truncaion also got rollbacked.Same goes with "Commit transaction" in the third steps(if a replace Rollback with Commit).
I don't understand this strange behavior.
Any clue is highly appreciated.
My real problem is I want to rollback a transaction, if Truncate table step fails.
