Inserting Data Into A Row With An Identity Specification
May 5, 2008
I am trying to build a Windows application using: Windows XP Pro ; VS Pro 2005, C# and SQL2005.
I have a database table as follows:
eg
1) myGameRecency which contains columns : GameId (identity specification column/primary key/not null), Date (not null), [1], [2], [3], [4]
Using the myGameRecencyAllBalls table ---
I wish to insert a date into a new row but have not been able to determine how to with the identity specification on the GameId column.
Can anyone please assist?
Thank you.

sqlCmd.CommandText = "DECLARE @date datetime SET @date = '" + Date +
"DECLARE @lastRowGameId int " +
"DECLARE lastrow_gameidcursor CURSOR SCROLL FOR " +
"(SELECT GameId FROM " + DBGameName.ToString() + "RecencyAllBalls) " +
"OPEN lastrow_cursor " +
"FETCH LAST FROM lastrow_gameidcursor INTO @lastRowGameId " +
"' INSERT INTO " + DBGameName.ToString() + "RecencyAllBalls.Date VALUES (@date) WHERE GameId = @lastrow_gameidcursor + 1";
Hi, I am having a bit of hassle with trying to enter details to multiple tables in SQL Server 2005. I have four tables, an Attendance Table (AttendanceID(PK Identity specific), MembershipNo, Date) Resistance Table (ResistId(PK Identity specific), Weight , Reps, Sets) Aerobics Tables(AerobicsID(PK Identity specific), MachineID, Intensity, Time) and a linking table for all of them.... ExerciseMaster(AttendanceID,ResistanceID,AerobicsI D)
My problem is that I can insert data to each specific table by itself using seperate insert statements.....eg....
//insert an attendance record to the attendance table string userID;
userID = Session["User"].ToString();
SqlDataSource pgpDataSource = new SqlDataSource(); pgpDataSource.ConnectionString = ConfigurationManager.ConnectionStrings["ConnectionStringLogin"].ToString();
finally { pgpDataSource = null; } //same code as above for the resistance table
However, i am facing the problem where this does not populate the link table(ExerciseMaster) with any information as i am unable to write the relevant IDs into the table that have been auto generated by SQL Server for each of the subTables. I have read several forums where they recommend using something called @@IDENTITY but i have no idea how or where to use this in order to fill my exercise table... Any help would be so much appreciated.... Also, hopefully what i have said all makes sense and someone will be able to help me...oh and one more thing...this is an ASP.NET page coding in C# Cheers Scotty
Using Management Studio, when I import data from one identical database to another, any identity specifications get dropped from the destination database.
(From columns which have them on the source database and which had them on the destination database.)
Hi, How do I determine what the next "id" will be in a collumn where the Identity Specification is turned on with Identity Increment? I have two tables, the one contains product information and the other is a photo album. When I create a new product, then I automatically create an associated photo album. It all works fine, but I have found some problems after using this setup for a while to manage products. For example, say I have created 10 products (id's 1 to 10) , and then I decide to remove the last 5 products from the list. The next time I add a new product, it will be product number 6, but the id will be 11 (seeing that the id's will always be unique). How do I determine what the next Identity value will be seeing that the actual last id might not be the last one that was allocated? RegardsJan
I am not very clear about the use of 'identity specification properties'. There does not seem to be a great use of identity increments and seeds, it seems something that saves manual work, but to a very little extent Anyone willing to shed some light?
what happens when a column marked as Identity Specification reaches the limit? for example, I have some code tables using tinyints as keys, the actual number of entries will be 20 or so but there is some volatility, so eventually the 255 limit will be reached, what happens then?
the same thing applies to ints or bigints used as keys, eventually the database must run out of numbers
I am using SQL Server 2005 Mobile Edition & Merge Replication
in this I want to insert a record into table, in that table I have taken UserID coloumn as auto incrementing Identity type.
In a book I read that, If you are using an Identity column, you must find the next available number and reseed before an insert can be successful. You will also have to set up ranged identity columns on the published database to prevent errors when the new data is merged.
Now I want to ask here that, how should I ressed that value before inserting?????
any help in a form of CODe will be appriciated.....
First of all, I'm new to the forums, and I'm still getting started with VBEE and SQL.
I'm building a simple Windows Application that has a SQL Database with three tables, related to each other. In all of them I need to set one column as a simple index for the rows (1, 2, 3... etc), to work as a PK and relate to the other tables' FKs.
I've set the property Identity Specification of the column to Yes, and added some rows of data for testing. If you just keep adding rows, the PK columns work fine, but if you start deleting rows, the numbering gets fragmented, and the relations between the tables lose integrity.
I've tried the MSDN Online Help topics, but they just tell you this:
If an identity column exists for a table with frequent deletions, gaps can occur between identity values. If you want to avoid such gaps, do not use the identity property.
So, my questions are: is there another way around this problem? How to number rows automatically and re-number them when a row is deleted, and keep the table relations working? It has anything to do with constraints?
Sorry if my question was already answered, I really couldn't find anything like my problem searching the forums. Thanks in advance.
subject says it all -- is it possible to automatically expand the identity specification node in table properties for the Management Studio or VS2005 diagram mode? when creating a DB, it seems ridiculous that for EVERY table I have to add an extra click to get to just one more clickable item that ought to be exposed by default.
If I right click on a primary key in SQL Server management studion, I can set the identity specification for a primary keyId so that it is indexible. I do this by setting the properties for "Is Identity", "Identity Increment", and "Identity Seed". This is wonderful, but I have been asked to perform this using a script instead of the SQL server GUI/Sql Server management studio. Is this possible? Does anyone know how to do this? If so, can you show me how? Ralph
Someone asked me the other day about creating a table with one column that is an identity field and doing an insert so they can capture the SCOPE_IDENTITY() to use across seferal tables. I've never done anything like it and it seemed trivial at the time, but I'm not seeing how to make an insert work. So, for example, we have a table defines as: DECLARE @Bar TABLE (ID INT IDENTITY(1, 1) NOT NULL) Now, how do you write a simple insert statement that will add a row to the table?
Basicaly, this is an acedemic exercise, but I can't seem to make it work unless I add another column to the table. Any ideas? Maybe I'm not caffinated enough..? :)
I have an odd issue with a stored procedure using output parameters and a database text field.
I am using custom VB6 COM+ objects in the middle tier and SQL Server 2000 on the back end. The stored procedure has an int as it's first parameter; it is an output parameter which gets set to @@IDENTITY after the data is written to the tables. The last parameter is a text.
The COM+ object executes the proc; ADO 2.7 incorrectly identifies the text parameter as an adVarChar, so I explicitely convert it to an adLongVarChar when I detect that the incoming data is > 8000 characters.
The proc writes the data correctly to the database in all cases. However, when the data is > 8000 characters, SQL doesn't appear to correctly set the output variable. No errors are generated, I simply don't get any value written to the variable. I've searched through MS's documentation, but can't seem to find anything on this issue.
I need to insert values from a text-file to a table with a primary key as identity. In the text file I have no idea of the primary key values and i get "foreign key constraint violation" when trying to import null values into the column.
How can I solve the problem? With ordinary insert-statement there is no problem since the table generates identity- key values automatically. Is there a possibility to generate identity values with DTS-import?
I have a table with the following schema: CREATE TABLE [itis].[wrk_taxon_authors] ( [wb_taxon_author_id] [int] NOT NULL , [taxon_author_id] [int] IDENTITY (1, 1) NOT NULL , [taxon_author] [varchar] (100) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL , [kingdom_id] [smallint] NOT NULL ) ON [PRIMARY] GO
I am trying to insert the following data (as you can see fields are seperated with the | ):
19||Flores-Villela and Sánchez-H., 2003|5| 20||Wiegmann, 1828|5| 16|17482|Gray, 1838|5| 17|9823|(Wiegmann, 1828)|5| I get the following error:Server: Msg 4869, Level 16, State 1, Line 1 Bulk Insert failed. Unexpected NULL value in data file row 1, column 2. Destination column (taxon_author_id) is defined NOT NULL. Server: Msg 4869, Level 16, State 1, Line 1 Bulk Insert failed. Unexpected NULL value in data file row 2, column 2. Destination column (taxon_author_id) is defined NOT NULL.
Since I have defined column 2 as an identity column, I don't understand why SQL Query analyzer is upset when I do not have a value in that field. To me, I would think it would auto-insert an integer (starting at seed 1 and incrementing by 1), but it doesn't. Could someone tell me what I'm doing wrong?
I have a database that has a tble with a field that autoincrements as a primary key. meanig that the field type is BigInteger and it is set up as my Identity Column. Now when I insert a new record that field gets updated automaticly. How can I get this value in the same operation as my insert? meaning, in 1 sub, I insert a new record but then need to retieve the Identity Value. All in the same procedure. Waht is the way to achive this please? Marc
We are in the conversion process of making the database ints.This is a change from a guid PK to an integer based PK that uses an int Identity. The program still uses the guid, and we are trying to map that guid to the databases int.We insert using TVPs passed from code. Since the identity is being set upon insert I have three things to accomplish:
1) Insert all the data into the dbo table 2) Update the parent Id in the table 3) Pass the SetsId guid, Sets_Id int, ParentSets_Id int back to the program
This is a high transaction table that will have a lot of records (millions).
--Sample table creation. There is a FK between Sets_Id to ParentSets_Id, Clustered PK on the Sets_Id IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[JSets]') AND type in (N'U')) BEGIN CREATE TABLE [dbo].[JSets]( [SetsID] [uniqueidentifier] NOT NULL, [Sets_Id] bigint Identity (1,1) NOT NULL,
I am having troubles trying to copy some rows from a table on my local computer to a table on a remote SQL Server 2005 that is being hosted by one of thos web hosting companies. The problem is that the table has an identity column. I first tried using the the following command:
SET IDENTITY_INSERT [remoteservername].Library2005.dbo.tblLanguages ON
but that results in the error:
Msg 8103, Level 16, State 1, Line 1 Table 'remoteservername.Library2005.dbo.tblLanguages' does not exist or cannot be opened for SET operation.
I read in another topic, that I should change this into the following:
That command executes without error, but the problem is that I cannot perform the actual insert, because it is not within the execute statement. In other words, the following doesn't work:
EXECUTE [remoteservername].Library2005.dbo.sp_executesql N'SET IDENTITY_INSERT dbo.tblLanguages ON' INSERT INTO [remoteservername].Library2005.dbo.tblLanguages (colLangID, colEnglish, colGerman, colSpanish) SELECT colLangID, colEnglish, colGerman, colSpanish FROM tblLanguages
This results in the error:
Msg 7344, Level 16, State 1, Line 2 OLE DB provider 'SQLOLEDB' could not INSERT INTO table '[remoteservername].[Library2005].[dbo].[tblLanguages]' because of column 'colLangID'. The user did not have permission to write to the column.
The remote server is linked correctly on my end via the sp_addlinkedserver and sp_addlinkedsrvlogin. Is there any way to force the remote server to turn IDENTITY_INSERT ON permanently and then let me execute as many INSERTS as I want and then turn it back OFF?
Is it possible to insert the identity cloumn in a table via SSIS. I've an ID (Identity) column is a table and I am importing data in the table using Excel sheet. I want to insert the value of ID column as Identity(1,1).
Hi, All:Please help. I use sql server as back end and Access 2003 as front end(everything is DAO).A table on SQL server has an identity column as the key.We have trouble on adding records to this table using the following SQL.strSQL = "INSERT INTO myTableOnSQLServer (A, B, C, D, E) SELECT A, B, C, D,E FROM myTableonAccessLocal"db.execute strSQLThe schema of the table "myTableOnSQLServer" and the schema of the table"myTableonAccessLocal" are all the same except that the "myTableOnSQLServer"has an identity column (ID). The key of the "myTableOnSQLServer" is "ID" andthe table "myTableonAccessLocal" does not have a key.When we try to run the query, it gives errors indicating the key is violatedor missing.Should I figure out the autonumber for it first and then add to the SQLserver table?Many thanks,HS
I am writing an Instead of Insert trigger. I would like to fire an error when inserting into an 'Identity' column. Since UPDATE([ColumnName]) always returns TRUE for insert statements, is there an easy/fast way around this? I don't want to use:Â
IF(EXISTS(SELECT [i].[AS_ID] FROM [inserted] [i] WHERE [i].[AS_ID] IS NULL)) here is my pseudo-code... CREATE VIEW [org].[Assets] WITH SCHEMABINDING
[Code] .....
-- How does this statement need to be written to throw the error? --UPDATE([AS_ID]) always returns TRUE
IF(UPDATE([AS_ID])) RAISERROR('INSERT into the anchor identity column ''AS_ID'' is not allowed.', 16, 1) WITH NOWAIT;
-- Is there a faster/better method than this? IF(EXISTS(SELECT [i].[AS_ID] FROM [inserted] [i] WHERE [i].[AS_ID] IS NOT NULL)) RAISERROR('INSERT into the anchor identity column ''AS_ID'' is not allowed.', 16, 1) WITH NOWAIT;
-- Do Stuff END;
-- Should error for inserting into [AS_ID] field (which is an identity field) INSERT INTO [org].[Assets]([AS_ID], [Tag], [Name]) VALUES(1, 'f451', 'Paper burns'), (2, 'k505.928', 'Paper burns in Chemistry');
-- No error should occur INSERT INTO [org].[Assets]([Tag], [Name]) VALUES('f451', 'Paper burns'), ('k505.928', 'Paper burns in Chemistry');
Why would I get these errors: " SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80040E21. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E21 Description: "Invalid character value for cast specification".

I read related posts but could not figure out the error?

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 insert data into two different tables. I will insert into Table 2 based on an id I get from the Select Statement from Table1. Insert Table1(Title,Description,Link,Whatever)Values(@title,@description,@link,@Whatever)Select WhateverID from Table1 Where Description = @DescriptionInsert into Table2(CategoryID,WhateverID)Values(@CategoryID,@WhateverID) This statement is not working. What should I do? Should I use a stored procedure?? I am writing in C#. Can someone please help!!
I want to write a query where I can see all races and age range as column.
TblRace
ID, RaceName
TblAgeRange
ID,AgeRange.
There is no connection between this two table. I need to display result like below.
Race 17-20 21-30 31-40
A
B
I
W
How do i get this kind of empty data set so that I can fill it out in front end or any better solution. The age range will be displayed as many row as they have. It's not static. Above is just an example.
I have data for online catalogue in SQL 7.0. The web grogrammer asked me to add a unique key for reference. I used int datatype with identity seed of 1 and increment of 1. This works fine BUT when I try to import new data I get an error because the csv file has no column and therefore no value for the unique field which will not allow null by definition.
How can I maintain a unique field to act as primary key in my data when I want to add (and delete) data that doesn't have this field.
I tried adding the uniqueidentifier field but this gives error message.
The only work round is to delete the unigue field altogether and then add the new data and afterwards create a new unique field. At 600000 + lines of data, this is time and memory consuming
I have some website work lined up and it involves some simple modifications to a MS SQL 2000 server. What I'll need to do is add some new data fields and insert some data.
I have some experience with databases - MS Access and MySQL, but I have never used or seen MS SQL 2000. My question is, is this a relatively simple thing to do for someone who hasn't used it before? I can do these things quite simply in Access or MySQL, so is MS SQL 2000 going to be any different?
Also, does anyone know of any free tutorials online that would help me out?
Hello friends.... I am looking for 2 things(using c#.net or vb.net and sql svr 2000) 1.convert data from sql server 2000 database (say customers table from northwinds database) to a text file(separated by commas or just plain space) 2.Insert the data from text file back to database. Can someone pls give me the detailed code to achieve this....really need this on urgent basis.......Thank You.
Hi,I m using Microsoft Visual Studio 2005 and SQL server 2000. I have 2 textboxes and a button, what i wanna do is, when i hit the button, the values in textboxes should be inserted into DB. Would you please help me? Thanks in advance.
Hi friends,I have one text box on my form.i need to insert the data from tat text box to DB without clicking on any button.Now i have written the code under text changed event of that text box.So it is inserting whenever i click on that form.Besides this i need to insert data when i close tat window.But it is not inserting when i close tat window.Plse help me.Thanks in advance With RegardsLijo Rajan
