How To Retrieve The Value Of Last Saved Identity Column ?
Oct 13, 2007
Hello Everyone,
I'm using Nhibernate and SQL Server 2005.
I have two tables something like this :
Table : Account
AccountID
UserName
Password
Table : Address
AddressID
AccountID
Line1
Line2
State
My NHibernate mapping file looks like this :
For Table Account
<id name="ID" type="long" column="AccountID" access="property">
<generator class="identity"/>
</id>
My Problem is it does entry in the Account table perfectly, but when it comes to do entry in Address Table it says AccountID can't be null, I'm wondering shouldn't it pick it up from the Account table as I'm passing in that object.
For the Workaround I was thinking maybe I can get the identity of the last entry saved and somehow save it to the other table myself.
I have a table with an Identity column. Is there a way to get the automatically generated primary key after I insert something to the table? If so, what is the syntax?
Using Visual Studio 2005 Prof and SQL Server everywhere.
How do get the identity column value after insert record.
With SQL Server 2005, its quite easy to get by creating and insert statement on the tabledapter ( Insert statement followed by a select statement where identitycolumn = scope_identity())
We're using ASPUpload as a tool to upload files to our server and savethe details to SQLServer. However, I have an application where I needto return the pkID of the just saved file. I'm assuming that I coulduse the @@Identity command but cannot get this to function.Has anyone used this command with ASPUpload with an success, or anyother methods that could be used?Thanks.
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 a "newbie" and have been struggling with this for days! I have users enter their residence information and insert which generates houseid. I want to use/display that houseid on next page/step.

Ok I've been researching this for a day now and I'm not coming up with much. I want to store the auto-incrementing ID of the last inserted record in a session variable, so that I may put it in a foreign key column in another table, if the user wishes to fill out a form on another page. I think my stored procedure is correct. But don't know what code to add to my aspx page. Any help will be greatly appreciated.
Here is my VB ScriptProtected Sub submitButton_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim personalContactDataSource As New SqlDataSource()personalContactDataSource.ConnectionString = ConfigurationManager.ConnectionStrings("DataConnectionString1").ToString()
Best way to retrieve the identity key of the record just inserted?This question is for discussion purposes; the business process that spurred the question is currently working.Using SQL Server 2008 R2, a record is inserted from a stored procedure. Let's say the sp has something like this:
Code: BEGIN BEGIN TRANSACTION INSERT INTO tblTools ([Desc],CreateDate,Model,CreatedBy,Notes)
[code]....
In Access, when you add a new record to the recordset, the identity field comes "pre-populated" making it east to get the actual, correct identity value assigned to the record you are inserting. In SQL Server, I know options include:
Code: IDENT_CURRENT('tblX') SCOPE_IDENTITY @@IDENTITY among other methods.
Each has pros and cons, such as user privileges (IDENT_CURRENT requires the user to have Select privileges on the table, and catches records created by other things, such as users and triggers), and the other two give you the last key inserted and don't allow specifying the object (which is a problem if the insert added records to multiple tables, or you have multiple inserts).
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'.
Is there a clever way of reteiving the identity of an INSERT query in SQLServer?
The example below is a the first insert (into the "parent" table with an identity column) of a heirarchical multi-table update.
sqlCommand.CommandText = "INSERT INTO Orders VALUES ( Date, Customer ) ; SELECT @@IDENTITY AS ID" ; sqlCommand.ExecuteNonQuery() ;
The ExecuteNonQuery() method returns the number of rows inserted but I need the ID for the INSERT into the "child" table.
My options based on my current understanding appear to be: a) use command parameters and set ID as an output param b) use a stored procedure, use command parameters and set ID as an output param c) issue the SELECT @@IDENTITY as a subsequent seperate command using ExecuteScalar()
Is there a more elegant way to get the ID using SQLServer's "batch" query mechanism and ADO.NET v1.1? Thanks,
I am working in an environment where i inherited bad design. I have a column in a table. This col contains huge HTML files. We are mostly reading these files and very little updates.
I am changing this whole architecture and going to using Azure Blob storage. I am stuck right now. I need to extract these html strings and save them into separate files in year/month/day/filename.html format. I have another column in the table which has create date saved in it.
I am planning to import all these files into BLOB storage and save link in the table.
1) How can i extract these strings from the table and save them in the year/month/day/filename.html directory/sub-directory format
This is a pretty simple question, but I'm going nuts trying to find the answer. After creating an SSI package, I told it to save to the SQL server... Now where do I go to pull that package up again and make changes and/or execute the package?
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'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

Hi, all.. I want to know the query to retrieve Column information that we can see from table Design view of Enterprise manager, such as Column name, Pk or not, FK table, Data Type, Null or not, Description(Specially Descrition).
I have search for and see how to put the columns for the last, first mi together (Name_Last + ', ' + Name_First + ' ' + Name_MI) as Name But how can I test the value of the Name_Type field to determine how the Name column looks if Name_Type = 1 then Name = (Name_Last + ', ' + Name_First + ' ' + Name_MI) else Name = Name_Last
The Name_Type represents Individual versus an Entity 0,ABC Pipeline,, 1,Williams, John,A
I am trying to retrieve all rows with the largest value in a particular column. The largest value could return many rows for a particular users. Here is what I have thus far.
SELECT DISTINCT ID, NAME, FOP, ACCT, CTNUM, ENDDATE, DEBIT, CREDIT, TRANSACTION_DATE, EXPORTED, CALENDAR_YEAR, FISCAL_YEAR, PAYROLL_IDENTIFIER, PAYROLL_NUMBER, [EARN-SEQNO], EVENT_SEQUENCE_NUMBER FROM (SELECT *, ROW_NUMBER() OVER (PARTITION BY ID, ACCT, PAYROLL_NUMBER,EVENT_SEQUENCE_NUMBER ORDER BY EVENT_SEQUENCE_NUMBER DESC) AS RN FROM PAYROLLYEAREND ) s WHERE RN = 1 AND ID = '16443' AND PAYROLL_NUMBER ='7'
In the above example, the EVENT_SEQUENCE_NUMBER is populated with values from 0 to 12. Could vary per user and PAYROLL_NUMBER. The query above returns 48 rows. However, all I want are the rows where EVENT_SEQUENCE_NUMBER is equal to the highest, which is in the above example is 12. The result would be 29 rows. The where clause is not part of overall query. Just isolating on one ID.
What would be the most efficient method of constructing a sql statement to retrieve certain record into (this gets tricky) rows of a table with 3 columns date.desc.
Is there any way to retrieve partial contents of a database column? For example, say a column holds 5,000 characters, but I only wish to retrieve the first 50. Thanks
I want to just retrieve the numbers left of the space in this address column what can I use? The Address column is Varchar.
Address: 6501 Red Hook Place #201 32 Orchard St 1 Hardy Rd ste 210 379 E Center St. 170 Bridge St 399 Interpace Pkwy 1800 Valley Rd 2210 Harding Hwy 41 Maple Ct
Expected Results:
Address 6501 32 1 379 170 399 1800 2210 41
I tried using this:
Left([ADDRESS], Charindex(' ',[ADDRESS] - 1)) as 'Address'
But i received an error:
Conversion failed when converting the nvarchar value '6501 Red Hook Place #201' to data type int.
We have a SSIS project where we load lot of image files using an OLE DB Source component and put it across the database as varbinary into OLEDB Destination component.
Things were fine until now where am getting an error like this. alongside the log also reads like,
There is not enough space on the disk. Long data was retrieved and can't be added to the data flow task buffer.
Is this method of loading the files using an OleDb Souce not the efficient one ? If not is there a way I can get this done. Comments are highly appreciated!!
