Update And Delete Stmt.
May 11, 2007
Hi,
I have two tables:
1. RubricReport
2. RubricReportDetail
How can I code this step in my stored procedure:
If @ReportID is NULL, insert a row into RubricReport table, and set @ReportID=@@IDENTITY; otherwise, update table RubricReport for columns LastUpdate and LastUpdateBy, and delete table RubricReportDetail where ReportID=@ReportID.
Table RubricReport has columns ReportID, County,Dsitrict, DataYears, LastUpdate and LastUpdateBy
Table RubricReportDetail has columns ReportID, IndicatorID, LocalPerf
Kindly help me.
Thanks in advance

We have a MS SQL Server 6.5 database table with 643,000 records.
There are several indexes including some clustered indexes.
We do a statement: update wo set udf3 = '1234567890123456' where woid = '123'
this returns immediately.
Then we try the same statement where the string is 1 character longer and it
takes 45 minutes to return. There is no indication of what the server is doing
during this time.
There is no index on UDF3 and WOID is the primary key.
Any suggestions what is happening? What can we do to correct it?
DBCC CheckTable finds no errors.
name rows reserved data index_size unused

I have a relatively simple update statement that runs fine from Query Analyzer and Enterprise Manager (two rows updated in less than 1 sec) but times out when I run it from a VBScript file.
Any ideas?

Hi all,I am doing the change from having worked in Oracle for a long time toMS SQL server and am frustrated with a couple of simple SQL stmt's. Orat least they have always been easy.The SQL is pretty straightforward. I am updating a field with a Maxeffective dated row criteria. (PepopleSoft app)update PS_JOB as A set BAS_GROUP_ID = ' 'where EMPL_STATUS in ('D', 'L', 'R', 'S', 'T')and EFFDT = (select max(EFFDT) from PS_JOB where EMPLID = A.EMPLID)This stmt is not working. I am getting an error on the keyword 'as'. Ihave tried:update PS_JOB A set...update PS_JOB from PS_JOB A set...Same result, error on 'A' or error on 'from'.I also tried to add the table alias to the sub query, whichtechnically worked, but with wrong data result.So my question comes down to: How do I use a table alias in an updatestatement in MS SQL server?I worked around this by creating a temp table. But that does notfulfill my curiosity, nor is it an ideal solution.Thanks a lot,-OK

If we want to maintain the data in relationships.
There are two ways to do it.
1. Auto (Like Cascading Update And Delete)
2. Manually (Like In Stored Procedures)
I read an intresting article
http://imar.spaanjaars.com/QuickDocId.aspx?quickdoc=419
In this article Imar has choosen the second way (Manually).
And when I talk to Imar.
He said, "Cascading deletes would have worked equally well in this situation. However, I personally don't like them too much. I am much rather in control, enabling me to delete what I want and when I want it. I could, for example, keep certain data for "time travelling scenarios" (e.g. the state things were in some time ago) or I might want to keep it for other purposes."
Can any one help me to choose the better one.
Waiting for helpful replies.

Hi All,
I have this project I'm working on it's Product Content Management System rewrite. I got to the point of updating the Product By Sku and not sure if I should use UPDATE statement or I should DELETE sections assosiated with the ProductContentID and then re-insert them again? I'm not sure which is more afficient?
I can really do both and it's really not that complicated, the only problem I see with DELETE then INSERT is the ProductContentSectionId in the Sections table is going to grow very fast and I'm a bit concerned about it.
We use SQL Server 2000 and we have about 4 bound tables where we keep the data. The one I'm talking about is the sections table where we keep the actual types of product content like a BoxShot, Description, Key Features and so on...
Thank you in advance!

I have two buttons on my page, one which will update content the other which will delete content from my slq database.
I get this error "CS1501: No overload for method 'updateBlockContent' takes '2' arguments" when I click on my update button.
I get this error "CS1501: No overload for method 'deleteBlockContent' takes '2' arguments" when I click on my delete button.
This is my method for updating - UPDATE [CMS] SET [BlockName] = @BlockName, [BlockContent] = @BlockContent WHERE (([BlockID] = @Original_BlockID))
This is my C# code behind the update button:protected void btnUpdateBlock_Click(object sender, EventArgs e)
{CMSTableAdapter ta = new CMSTableAdapter();
try
{
ta.updateBlockContent(txtBlockName.Text, txtBlockContent.Text);lblFeedback.Text = "Block Updated.";txtBlockName.Text = txtBlockContent.Text = "";
}
catch (Exception ex) { lblFeedback.Text = ex.ToString(); }
finally
{lblFeedback.Visible = true;
ta.Dispose();
}
}
This is my method for deleting - DELETE FROM [CMS] WHERE (([BlockID] = @Original_BlockID))
This is my C# code behind the delete button:protected void btnDeleteBlock_Click(object sender, EventArgs e)
{CMSTableAdapter ta = new CMSTableAdapter();
try
{
ta.deleteBlockContent(txtBlockName.Text, txtBlockContent.Text);lblFeedback.Text = "Block Deleted.";txtBlockName.Text = txtBlockContent.Text = "";
}
catch (Exception ex) { lblFeedback.Text = ex.ToString(); }
finally
{lblFeedback.Visible = true;
ta.Dispose();
}
}
Can somebody please explain why this is happening and how to remedy this problem.
Thanks,
Chris.

hi,
I have a dataadaptor which i use to fill a dataset. I can do this no problems. But if I delete a row from the dataset and update the adaptor again, nothing gets changed in my source database. Does anyone know why this is?
here's my code for my dataadaptor:
SqlConnection conn = new SqlConnection(connectionString);
SqlDataAdapter adapter = new SqlDataAdapter();
adapter.SelectCommand = new SqlCommand("select * from tblExtRef", conn);
adapter.SelectCommand.Connection = conn;
SqlParameter parm;
SqlCommand cmd;
cmd = new SqlCommand("DELETE FROM tblextref WHERE extrefid = @extrefid",conn);
parm = cmd.Parameters.Add("@extrefid", SqlDbType.Int , 40, "extrefid");
parm.SourceColumn = "ExtRefid";
//parm.SourceVersion = DataRowVersion.Original;
//parm.Direction = ParameterDirection.InputOutput;
//SourceVersion = DataRowVersion.Original;
adapter.DeleteCommand = cmd;

I am trying to update a SQL database with data from a Wang system. The Wang data is dumped to a txt file. I then import it into an update table in SQL via Access. Some of the data is new and some of the data is updated records. At this point I have been trying to create a script to update and add data to a table via the query tool in SQL Then delete data from the update table.
I was able to get the UPDATE and DELETE to work but I have not figured out how to insert new records at the same time? Can I use an IF statement? I will apreciate any help or sample code, Thanks.
UPDATE MemberList
Set Name = NameUpd, Address1 = Address1Upd, Address2 = Address2Upd, City = CityUpd, State = StateUpd, ZipCode = ZipCodeUpd, MemberStatus = MemberstatusUpd
FROM MemberList, MemberListUpd
WHERE MemberList.MemberNumber = MemberListUpd.MemberNumberUpd
INSERT ?
DELETE MemberListUpd

I know how to do this in MySQL; but I was hoping there was a way to do it in MS SQL.
I want to be able to limit the number of rows an UPDATE or DELETE will effect regardless of the WHERE clause. I want to do this as a stop gap in the event that there is a logical error in the WHERE clause that would make it effect more rows than is humanly intended.
If I write a complex query that I know should drill down to only affecting one row, I just want to lock it in before I run it on database and take the risk of damaging some data.
In MySQL you would just do something like this:
Code:
DELETE FROM table_name WHERE ... LIMIT 1;
The only thing close to LIMIT I could come up with for MS SQL was TOP but it seems to only work for SELECT.
Any ideas would be greatly appreciated.
I ask this because if you screw up; manually saving 1, 2 or even 5 rows is a lot easier than having to rescue a whole table of data (even if it on a development server).

Im trying to keep a mirror image of some data Im getting from Quickbooks.
As the records are inserted into the database I need to check if a record exists and either update or insert a new one.
it seems easier just to delete using the tnxid and reinsert vs updating
my question is if I go
begin
INSERT INTO QBInvoicesQue(100s of feilds)
end
begin
delete from QBInvoices where txnid = @TxnID
end
and there is not matching txnid to delete from will it cause any problems? before going to the insert statement?
begin
INSERT INTO QBInvoices(100s of feilds)
end

Hi all!Are there any other way than using rights or Triggers to prevent aDELETE or an UPDATE on a specific column.The "problem" with rights is that they dont apply to all DB-usersThe "problem" with triggers is that they generate lots of extraSQL-codeI would like a solution something like below. If there are anyprimitives like this or other more neat solutions I would be glad toknowCREATE TABLE some_table NO DELETE/* ^^^^^^^^^*/(some_column SOME_TYPE NO UPDATE/* ^^^^^^^^^*/)For clarity, here is a trigger that currently solves the problemCREATE TRIGGER check_updateable_columns ON some_tableFOR UPDATEASIF UPDATE(some_column)RAISERROR(...)GOorCREATE TRIGGER delete_not_allowed ON some_tableINSTEAD OF DELETEASRAISERROR(...)GO

I vaguely recall reading an article that I can no longer find that an update statement is executed as a combination of a Delete and an Insert by SQL server. Does anyone know if this a still a true statement in SQL Server 2005?

HelloI have a Trigger on a table. Here is the code ALTER TRIGGER [dbo].[OnOrderDelete]
ON [dbo].[orders]
AFTER DELETE,UPDATE
AS
BEGIN
SET NOCOUNT ON;
DECLARE @ids int;
SELECT @ids =( SELECT id from DELETED);
DELETE FROM files WHERE OrderId = @ids;
ENDActually the UPDATE event handler is not wanted here, but why when I leave him I have a following behaviour:When orders table is updated, the "SELECT @ids =( SELECT id from DELETED);
DELETE FROM files WHERE OrderId = @ids;" part is executed, and the program recognizes DELETED as UPDATED! (Like " SELECT @ids =( SELECT id from UPDATED) ") Is this right? And how can I part UPDATED and DELETED ?ThanksArtashes

Hi, I have a database which saves data about bus links. I want to provide a information to passenger about price of their journay. The price depends on three factors: starting busstop, ending busstop and type of ticket (full, part - for students and old people, ...).
So I created a table with three foreign key constraints (two for busstops and one for type).
When the busstop is deleted or type of ticket I want all data connected with it to be deleted automatically. I wanted to use cascade deleting.
But I receive a following exception: Introducing FOREIGN KEY constraint 'FK_TicketPrices_BusStops1' on table 'TicketPrices' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints.
How can I achieve my task? Why should it cause cycles or multiple cascade paths?

for now, doing a small school project, i find doing SPs for Insert useful, like checking for existing data and not inserting, that might not be the best method, i had advice from here i can use unique constraints instead, then what about update and delete? SPs also? the pros make SPs for everything? currently use dynamically generated SQL from SqlDataSources. for Update / delete. some delete are SPs too...

I have recently started an ASP.Net application and am having some issues updating, inserting and deleting rows. When I started working with it, I was getting errors because it could not find any update command. Eventually, I figured out how to automatically generate the commands, by configuring my SQLDataSource control and clicking the "advanced" button. Right now though, I have generated the commands, but I still can not insert, update or delete rows. When I attempt to update anything, I recieve an error that says "The data types text and nvarchar are incompatible in the equal to operator." Nowhere in my table do I have any rows that use the datatype "nvarchar", only "text" and "int". I tried switching all of my text columns to "nvarchar(500)", which did not help. I am led to believe that the auto generated SQL procedures are trying to do something behind the scenes that is making my database act up, because even when I delete rows, I get the same exception, so the datatypes cannot be messed up there, because all that the datasource is doing is deleting rows, therefore there is no need to worry about data types. I only get the error when I check the "Use optimistic concurrency" box. When I do not use optimistic concurrency, I can delete, insert, and update rows... but nothing happens. There are no errors, but nothing is deleted, updated or inserted either. Upon postback, nothing has changed. I may upload a copy of the exact exception page, if someone thinks that it may help. Here is the update command that was generated: UPDATE [Record Information] SET [Speed] = @Speed, [Recording Company] = @Recording_Company, [Year] = @Year, [Artist] = @Artist, [Side 1 Track Title] = @Side_1_Track_Title, [Side 1 Track Duration] = @Side_1_Track_Duration, [Side 2 Track Title] = @Side_2_Track_Title, [Side 2 Track Duration] = @Side_2_Track_Duration, [Sleeve Description] = @Sleeve_Description WHERE [Record Database ID] = @original_Record_Database_ID
Apparently no stored procedures exist for any of these operations, and I am unsure why. The "Record Database ID" is my identity column, and is the only field that is (and is supposed to be) uneditable.

Hi,I just upgraded my ASP.NET 2.0 BETA 2 environment to the final release of ASP.NET 2.0 VWD.Once the update was finished, I could open my website without any problems..... Now, I noticed that in the final release, some modifications have been included in the Membership Stored Procedure and other stored procedures. So I created a new database (SQL Express) and added my data again.After re-creating my SQLDataSources, I tryed to enable the Editing and Deleting option in VWD and once I run my web application, it seems when selecting editing and then update, it doesn't work anymore....This is my code :

I've got four pages with in the first page a insert, in the second a select, in the thirth a update and in the fourth a delete statement. First the values of a textbox will be inserted in the database, then the values will be shown in labels and than it is possible to edit or delete the values inserted. Every inserted item belonging to each other has one ID. The follwing values has a second ID etc.
How can I make that possible?? I think that I should pass the ID's between the pages so I'm sure that I edit or delete the values that I want. So insert value 1 in page 1, show with select value 1 in page 2, edit or delete value 1 in page 3 and 4.
Maybe I didn't explain it good enough for you, please tell me then!!
Thanks!!

Well, I really messed up. Instead of changing the name of a current company record in a table I changed ALL the company names in the table. Me.CustomerDataSource.SelectCommand = "UPDATE tbl_customers SET company = '" & companyTextBox.Text & "'"
So, I need to insert a WHERE clause to fix this. My problem is that I've been searching everywhere for this simple command structure and cannot find anything that specifically addresses a simple way to reference the current record.
I tried...Me.CustomerDataSource.SelectCommand = "UPDATE tbl_customers SET company = '" & companyTextBox.Text & "' WHERE recno = @recno"
But I get the error:
Exception Details: System.Data.SqlClient.SqlException: Must declare the scalar variable "@recno".
Can anyone provide this simple query clause?

I have a table where I want to prevent user from deleting or setting a flag on a field to "y" with a database trigger (sql 2000). I understand the trigger for just one (stopping the delete, or stopping the field being changed to "y"). Should I have 2 seperate triggers or would there be a way to handle both.
