I am working with a table in SQL server. I have a column that I want to designateas an identity column. I am not able to do this, because the field for "Identity Specification" is not editiable. What I did was I went to sql server, right clicked and selected "Modify".The column properties dialog box/edit grid is then displayed with attributesthat I can modify. There are two major nodes in this dialog box. One is named "General" and the otheris named "Table Designer". I expand the "Table Designer" node and then go to the node labeled "Identity Specification" It is here where I would like to edit thevalues. The values that are listed for edit are listed below. BUT, the problem is thatI can place my cursor in those fields, but I am not able to change/edit them.Can anyone tell me what the problem is here? and how I can fix it? +Identity Specification (Is Identity) Identity Increment Identity Seed
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 am trying to design a Component which can be configured by a UI. After Configuration from the Design pane the Data should be passed to the back-end of the Component.
I'm using transactions with my SqlConnection ( sqlConnection.BeginTransaction() ).
I do an Insert into my User table, and then subsequently use the generated identity ( via @@identity ) to make an insert into another table. The foreign key relationship is dependant on the generated identity. For some reason with transactions, I can't retrieve the insert identity (it always returns as 1). However, I need the inserts to be under a transaction so that one cannot succeed while the other fails. Does anyone know a way around this problem?
So heres a simplefied explanation of what I'm trying to do:
Begin Transaction Insert into User Table Retrieve Inserted Identity (userID) via @@Identity Insert into UserContact table, using userID as the foreign key. Commit Transaction.
Because of the transaction, userID is 1, therefore an insert cannot be made into the UserContact table because of the foreign key constraint. I need this to be a transaction in case one or the other fails. Any ideas??
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'.
Hi.here is my code with my problem described in the syntax.I am using asp.net 1.1 and VB.NETThanks in advance for your help.I am still a beginner and I know that your time is precious. I would really appreciate it if you could "fill" my example function with the right code that returns the new ID of the newly inserted row.

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
When the CLR function executes "CREATE ASSEMBLY" the following error is thrown.
"Could not impersonate the client during assembly file operation."
The CLR function is invoked from Service Broker internal activation stored procedure.
"SELECT user_name()" returns dbo just before CREATE ASSEMBLY execution.
SqlContext.WindowsIdentity.Name is "NT AUTHORITYSYSTEM" as the Data Engine runs with the LocalSystem account.
How do I create a the necessary security context for "CREATE ASSEMBLY" to succeed ?
Service Broker Queue activation with EXECUTE AS = "SELF", "OWNER", domain account or dbo, all result in the above error. The Service Broker assembly having the internal activation stored procedure is registered "unsafe".
I try to create a Sproc which will use a cursor to retrieve a few rows from a table. But the cursor part has given me problem. Here it is:
StudentInfo StudentID StudentName DeptID 101 John 10 102 Alex 10 103 Beth 20 ClassInfo ClassID DeptID 901 10 902 10 225 20 I want to create a Sproc which will retreive the student's classes in DeptID 10
Following is the Sproc and cursor:
use master go Create PROCEDURE [dbo].[getEnclishClasses] @StudentID int AS Declare @printInsertStatement nvarchar(100) ECLARE NewRowID int
Declare classCursor CURSOR FOR SELECT ClassID, DeptID FROM [myTest].dbo.ClassInfo WHERE DeptID=(SELECT DeptID FROM [myTest].dbo.StudentInfo WHERE StudentID=@StudentID)
DECLARE @ClassID INT DECLARE @DeptID INT
OPEN classCursor FETCH NEXT FROM classCURSOR INTO @ClassID, @DeptID WHILE (@@FETCH_STATUs=0) BEGIN PRINT 'SET @newID = Scope_Identity()' SET @printInsertStatement= (Select 'INSERT INTO [myTest].dbo.ClassInfo (ClassID, DeptID) Values(' +CONVERT(NVARCHAR (10), @ClassID) + ',' +CONVERT(NVARCHAR (2), @DeptID)+')' FROM [myTest].dbo.StudentInfo WHERE DeptID=(SELECT DeptID FROM [myTest].dbo.StudentInfo WHERE StudentID=@StudentID))
PRINT @printInsertStatement END CLOSE classCursor DEALLOCATE classCursor EXEC getEnclishClasses 101
Here is what I try to get (text with actual data from the table): SET @newRowID = Scope_Identity() INSERT INTO [myTest].dbo.ClassInfo VALUES(901, 10) SET @newRowID = Scope_Identity() INSERT INTO [myTest].dbo.ClassInfo VALUES(902, 10)
Here is what I had got (returning multiple lines, more than number of records I have): Msg 512, Level 16, State 1, Procedure getEnclishClasses, Line 19 Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
Thanks in advance for your help! Or is it a better way (not using a cursor). Each table has over 5,000 records.
I am having problem with 'TOP @pageSize'. It doesn't work, but if I replace it by 'TOP 5' or 'TOP 6' etc., then the stored procedure runs without errors. Can someone please tell me how I could use @pageSize here so that it dynamically determines the 'n' of 'TOP n' ?
ALTER PROCEDURE dbo.spGetNextPageRecords
( @pageSize int, @previousMaxId int
)
AS /* SET NOCOUNT ON */ SELECT Top @pageSize ProductId, ProductName FROM Products WHERE (ProductID > @previousMaxId) order by ProductId RETURN
it seems like i am able to create it. But when i try to access that temporary table, i get an error "Invalid object". this is happening only when i try to create local temporary table. Global temporary table works fine inside the dynamic SQL.
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.
I have a package that loads data from a flat file, performs some transformations and then inserts the final data into a DB destination. The keys for the different DB records are generated in Script components in the Data Flow Tasks.
My question is concerning the Key Generation and I'll try to explain it on a simple example.
Package Structure:
The Control Flow contains two Data Flow tasks. Each of the Data Flow Tasks contains a Script Component responsible for generating the keys of the records to be loaded during this data flow.
The code of the Script component is the following:
' Field Definitions ' Private seed1 As Integer Private seed2 As Integer
' Constructor ' Public Sub New(ByVal dbSeed1 As Integer, ByVal dbSeed2 As Integer) ..... End Sub
' Generates the keys according to the seeds retrieved from the DB ' Public Function getNextKey() As Int64 ... ... Return generatedKey End Function
End Class
Public Class ScriptMain Inherits UserComponent
Private generator As New KeyGenerator(7, 5)
Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)
.... Row.NewKey = generator.getNextKey()
End Sub End Class
Questions: As you can see the KeyGenerator class code gets duplicated in each Script Component, which is definitely a bad practise. What I wish to do is to create the KeyGenerator class and deploy it as a library "somewhere". Then, in each Script Component, I should only import the KeyGenerator class.
1. Is that possible?
2. If yes, how can I do this?
3. If not, what is a best practise you would recommend which allows me to avoid this code duplication of the KeyGenerator class?
I need to find a way to query a value stored inside a table column. I have a piece of sample script that looks like this:
select convert(xml,[VALUE]).value('(/ROOT/app/@S_YEAR)[1]','numeric(4,0)') as S_Year from myTble where [KEY] = 'StringA'
The myTble has 2 columns, Key, Value, and the Value is of data type text. The data stored in there is a large xml node or doc. The table has only three rows for StringA, StringB, and StringC.
I feel bad that I cannot post the xml here because it contains a lot of sensitive data. It will be very hard for me to replace those sensitive data without breaking the syntax integrity.I used to know XPath, but couldn't make out above Select.
Hello, i need to create temporary table inside SP. i having one string variable @strQuery which contain dynamic query inside SP. i am executing that trhough execute sp_executesql @strQuery once query build.
now instead of select query , i want to creat hash table. so i wrote :
set @strQuery = "Select * into #tmp_tbl from table_name..." when i tried to execute it through
execute sp_executesql @strQuery , its giving error 'Invalid object name '#tmp_tbl' If i removed Hash then it works fine. even for double Hash also its work fine. but i want hash table only as i want that table local to that user.
Even direct execution of select statement without @strQuery works fine. but i want to execute @strQuery through execute sp_executesql @strQuery only as query is dynamic .
please guide me how to do this? its very urgent for me. thanks in advance.
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

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
Hi allIam using an SSIS package to import existing data from Oracle tables to SQl 2005 tables. I need to remove the identity from the sql table, import the data, then set the identity again to the sql table. Im doing that to maintain same ids as where in the Oracle tables. Is there a way that i can do that in an sql command.Any ideas?
I cannot manage to fetch the new timestamp value inside a TSQL Transaction. I have tried to Select "@LastChanged" before committing the transaction and after committing the transaction. A TimestampCheck variable is used to get the timestamp value of the Custom Business Object. It is checked against the row updating to see if they match. If they do, the Update begins as a Transaction. I send @LastChanged (timestamp) and an InputOutput param, But I also have the same problem sending in a dedicated timestamp param ("@NewLastChanged"): 1 select @TimestampCheck = LastChanged from ADD_Address where AddressId=@AddressId 2 3 if @TimestampCheck is null 4 begin 5 RAISERROR ('AddressId does not exist in ADD_Address: E002', 16, 1) -- AddressId does not exist. 6 return -1 7 end 8 else if @TimestampCheck <> @LastChanged 9 begin 10 RAISERROR ('Timestamps do not match up, the record has been changed: E003', 16, 1) 11 return -1 12 end 13 14 15 Begin Tran Address 16 17 Update ADD_Address 18 set StreetNumber= @StreetNumber, AddressLine1=@AddressLine1, StreetTypeId=@StreetTypeId, AddressLine2=@AddressLine2, AddressLine3=@AddressLine3, CityId=@CityId, StateProvidenceId=@StateProvidenceId, ZipCode=@ZipCode, CreateId=@CreateId, CreateDate=@CreateDate 19 where AddressId= @AddressId 20 21 select @error_code = @@ERROR, @AddressId= scope_identity() 22 23 if @error_code = 0 24 begin 25 commit tran Address 26 27 select @LastChanged = LastChanged 28 from ADD_Address 29 where AddressId = @AddressId 30 31 if @LastChanged is null 32 begin 33 RAISERROR ('LastChanged has returned null in ADD_Address: E004', 16, 1) 34 return -1 35 end 36 if @LastChanged = @TimestampCheck 37 begin 38 RAISERROR ('LastChanged original value has not changed in ADD_Address: E005', 16, 1) 39 return -1 40 end 41 return 0I do not have this problem if I do not use a TSQL Transaction. Is there a way to capture the new timestamp inside a Transaction, or have I missed something?Thank you,jspurlin
