Hi..
Code:
Update Table
Set Field=Field+1
Where Customer='pette.n'
after running this query how can I get identity number (ID)
after inserting a record, the command below gives the last identity
SELECT IDENT_CURRENT('Table')
is there a function like this for updating records
P.S. the only thing I can use in query is Customer value
Please excuse my ignorance. I've researched this and it appears I am asking to do something that is ridiculous, so please let me know what is wrong with my design (or my brain). I'd like to update an ID number in a table. It is an identity column. In my solution I'm adding a lot of new entries into my table and deleting old ones. Call me anal, but It's driving me nuts that my ID numbers are growing so large so quickly and that I have so many unused ID's. If you were to look over my data ID's they would be something like 1,3,45,78,88,89,103,140,219. What I'm trying to do is renumber my data so that my data currently at say ID# 1067 can be moved to the unused ID#2, etc. So I either need a way to update an Identity column...or I need a way find the lowest unused number among a list of ID's. So is there anyway to achieve what I am trying to do? I see this guy had my same OCD issue (without a solution) :-(

I am having problems updating my zip code table that contains zip, city, state, long, lat, ect..
I have the latest CSV file, I tried to use the import wizard in SQL Server 2000 Enterprise Manager.
I set the ID field as <ignore> and specified the appropriate columns for the rest of the data matching from CSV to already designed and working zip code table. Also I checked the box that said "Delete Rows in Destination Table" as well as "Enable Identity Insert" was checked
I ran the wizard, and now I have empty table and it will not insert any records because the error said that the identity column can not accept NULL.
What do I do? I am not updating the identify column so Is it telling me it can't insert NULL into ID?
Any suggestions...
Thanks,

I have met the interview question, I provide answer like the following from my experience. I don't know it is correct or need to supplement. Thank you for help.
Question: How to identity existing data for updating in SSIS?
Answer:
If you have the same key columns such as primary key or business key, you just use them to identify existing records from data source to destination.
If you use different key columns between data source and destination, you can create permanent link table which will store business key for data source and destination, and you can compare records from linking table when you update data.
I am very new to SQL Server 2005. I have created a package to load data from a flat delimited file to a database table. The initial load has worked. However, in the future, I will have flat files used to update the table. Some of the records will need to be inserted and some will need to update existing rows. I am trying to do this from SSIS. However, I am very lost as to how to do this.
Any suggestions?
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 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 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.

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
* I can't change anything on T
* The PK is NOT an Identity
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, I'm new to ASP.Net quite new to C# (My first attempt at a database website) and am trying to get a button to add "1" to "int" value called "Comments" a each time its pressed basically counting each time a comment is added. I also only wnat it to affect the row where "ModID" in my database is equal to the query string "ModID" I'm using on the page. I cannot find any tutorials so this is my best guess so far. This is probably a Noobie type stupid question but I'm stuck. This is the code I have so far for my Button_Click event: protected void Button_Click(object sender, EventArgs e){ SqlDataSource CommentCountDataSource = new SqlDataSource(); CommentCountDataSource.ConnectionString = ConfigurationManager.ConnectionStrings["Main_Site_DatabaseConnectionString1"].ToString(); CommentCountDataSource.UpdateCommandType = SqlDataSourceCommandType.Text; CommentCountDataSource.SelectCommand = "SELECT (ModID, DateTimeLastComment, Comments) FROM Mods"; CommentCountDataSource.UpdateCommand = "UPDATE Mods SET (DateTimeLastComment=@DateTimeLastComment, Comments=@Comments) WHERE ModID=@ModID"; //How do i get the Where to use the query string info? CommentCountDataSource.UpdateParameters.Add("DateTimeLastComment", DateTime.Now.ToString()); CommentCountDataSource.UpdateParameters.Add("Comments", "10"); //"10" is just a value to test I'll change this to add "1" once I figure how. CommentCountDataSource.Update();} Sorry if I'm using the wrong lingo but as I say I'm new. If my code is a mile off then please can you send me in the right direction of some code that works.Thanks in advance if anyone can help me. Cheers,Alan

I am a DBA who is moving in the direction of minor database design. I have gone through the steps to get my tables normalized, and I am ready to get them set up so they will update from table to table. How do I set this up? I know SQL does not cascade like Access, so how is this done? From what I have read (Robert Vieira's book) I should use triggers? Any help would be appreciated. Dallas

I have a database and when a form (C#) is loaded a copy of the table is made in a DataTable object. The form has a list box showing just the one column of info from the local DataTable.
On the form it is possible to change a record, delete a record and add a record. These are all done in the local table.
The question, how do i send these changes back to the database. Currently it deletes the lot and copies all the local table values in. How do only do the affected row, UPDATE, INSERT etc
Hey
I have an ASP application that uses a stored procedure and ADO.net to update a sql server data file. The problem is I know the code is working, I don't have any errors with the ADO, no exceptions are caught. I can use the same basic code to insert a record using a different procedure. It is the update procedure that does not carry through.
So, I know I have a connection, the procedure works using the query builder directly so the procedure works, but when I run the code, I get no errors and no update to the datafile. I am not even sure how to trouble shoot this since I don't have an error to look up.
C# Code:-------------
private void UpdateIssue()
{
DateTime date = new DateTime();
date = Convert.ToDateTime(this.txtDate.Text);
//edit record in HelpDeskIssuesTbl here.
SqlConnection con = new SqlConnection("Data Source...");
SqlCommand comUpdateTicket = new SqlCommand("sp_UpdateHelpDeskIssues", con);
comUpdateTicket.CommandType = CommandType.StoredProcedure;
comUpdateTicket.Parameters.Add("@IssueID", this.GridView1.SelectedIndex.ToString());
comUpdateTicket.Parameters.Add("@EmpID", this.ddlEmployee.SelectedValue.ToString());
comUpdateTicket.Parameters.Add("@Date", date.ToShortDateString());
comUpdateTicket.Parameters.Add("@StatusID", this.ddlStatus.SelectedValue.ToString());
try
{
con.Open();
comUpdateTicket.ExecuteNonQuery();
}
catch (Exception ex)
{
this.lblMessage.Text = "Data save error: " + ex.Message.ToString();
this.pnlMessage.Visible = true;

Hi gurus,
My feeling with the SCD component is not that very solid. I have the feeling that the behavior of the insert/update strategy is not always correct an working.
I will describe two problems that i encounter.
1. My destination table contains records with the value ''. Cause i don't want '' ( 2 single quotes) in our DWH i update the view that is the source with a case statement that changes the '' to NULL. But when i run the packages the '' values are not update with the NULL values. When i delete the destination table and run the package, the records are inserted with the NULL value as expected. Anyone who has experienced this problem?
2. When i create a new table and run the package so the destination table gets filled with records the SCD will insert alle records (for example 100). When i start the run directly after the first run, all records are updated instead of doing nothing what it should do cause all records exists.
Anyone who can give me some feedback?
with regards, Arthur
Hi
I come from a Unix backgound and used Informix ISQL quite frequently.
I have a row that contains a compund field 'cust_and_date' and contains a value of C0003 32656
I want to write an update statement that will amend the C0003 to C00009 but leaves the 32656 as is.
I tried the following:-
update scheme.slitemm set substring(cust_and_date,1,8) = 'C00009'
This returned a syntax error

Hi,I am currently updating a column in my database table with the value typed into a text box. But it is updating with the new value, rather than taking away the value typed in from the present value of the column. 1. How would i subtract the value typed in away from the current column value?2. I guess I need to check the column value is above 0 before updating, then rebind the control to show new values after the update has happened, incase two people are using it at once. How would this be achived?
