How Do I Update New Record Before It Is Committed?
Jun 9, 2008
I have a queue in service broker, which gets messages with a stored procedure which is invoked from VS application. The messages are properly stored in queue. I want to receive these messages one after the other and put it into a table. I am fetching the messages in a while loop which breaks when messages are over.
The first record is inserted properly. In the next iteration of the loop I want to append the next message data in that same record. This will continue for approximately 10 minutes after which a new record will be created. When I attempt to append the data in first record that record is not being read even though I have used isolation level read uncommitted.
What is it that I am missing to achieve the desired results?
I am inserting updating few tables from snapshot and reading same bunch of tables from reporting using readcommitted . It is showing some deadlocks i think it is write in this situation as " x" is not compitable with "s" ,"is".
I am trying to create package something like that..
1- New Customer table as OleDB source component 2- Lookup component - checks customer id with Dimension_Customer table 3- And if same customer exist : I have to update couple fields on Dimension_Customer table 4- if it does not exist then I have insert those records to Dimension_Customer table
I am able to move error output from lookup to Dimension_Customer table using oledb destination but How can I update the existing ones? I have tried to use oledb command but somehow it didnt work my sql was like this : update Dimension_Customer set per_X='Y', per_Y= &Opt(it should come from lookup)
I want to retrieve the last update time of database. Whenever any update or delete or insert happend to my database i want to store and retrieve that time.
I know one way is that i have to make a table that will store the datetime field and system trigger / trigger that can update this field record whenever any update insert or deletion occur in database.
But i don't know exactly how to do the coding for this?
I have a package loading up rows of employees from an excel file. An employee may be in the file multiple times. The package does a lookup and if not found it inserts the employee. When the employee is found it does an update.
So in my file employee A gets added on the first occurrence in the file. On the second occurrence, the lookup does not find the employee and tries to insert a second time and I get a unique constraint. How do I make the first insert Commit so that it is seen by the lookup on the second occurrence.
Hello, I am developing an application with a SQLExpress database. The database contains a very simple table, and I have added a Dataset object to the solution, and generated a plain Adapter object in the Dataset (using the standard VS wizard capabilities) to operate on one of the tables in de database. Just plain SELECT, INSERT operations, etc. Strange thing is, the data changes caused by the adapter's generated Insert command (which will call the INSERT statement on the database) are only visible while the application runs (or so it seems). For example: - I start off with the table containing 2 records, and start debugging- perform a COUNT within the code: 2 records- call the Insert function once from code- perform a COUNT within the code: 3 records- stop debugging- inspect the table: the 3rd record doesn't exist, just the 2 recordsSo, it seems that the changes don't get committed, although I am not sure it is a transaction/commit problem. I haven't been able to figure out what I can do to fix this. I have used adapters before on a SQL database, no problems there. Any comments appreciated. Cheers, JP
Consider this example please. BEGIN TRAN insert into OrderDetail (fields) VALUES (values) insert into Orders (fields) VALUES (values) COMMIT TRAN
If there is a trigger on Orders that takes some fields from OrderDetail and puts them into some other table.
When the trigger fires, can it find the details if the COMMIT has not occurred yet.
I'm wondering If I should use isolation level READ UNCOMMITTED. After all, If the whole transaction rolls back, my trigger activity will be rolled back as well. Comments?
I got problem in production server at client place(No backup copy & not replicated,it's a SQL SERVER 2000 Enterprise server),by mistake client updated the data without using where condition then updated lakhs of rows (in SQL server autocommited),Now I need to recover this data from LOG file(.ldf).I tried with LOG EXPLORER(Third party tool) Trail version recovered from default database(Northwind,Pubs).But client not willing purchase this S/W for simple cause,How can we recover the data from LOG file.
1.Can we write the Program in C# to read the SQL Server Log and show the past transactions? 2.Is There any Stored procedures exist in SQL Server to read the day transactions in log file and take the backup? 3. How to read Transactions Log file in SQL Server 2000?
It's very Urgent,I am not expert in SQL Server 2000.
I have a question on locking pattern of read committed with snapshot isolation level that when two transaction update two different records then why do they block to each other even if they have previous committed value (old version of record).
I executed the below batch from a query window in SSMS
--Session 1: use adventureworks create table marbles (id int primary key, color char(5)) insert marbles values(1, 'Black') insert marbles values(2, 'White') alter database adventureworks set read_committed_snapshot on set transaction isolation level read committed begin tran update marbles set color = 'Black' where color = 'White'
--commit tran
Before committing the first transaction I executed below query from second query window in SSMS
--Session 2: use adventureworks set transaction isolation level read committed begin tran update marbles set color = 'White' where color = 'Black' commit tran
Here the first session blocks to second session. These same transactions execute simultaneuosly in snapshot isolation level. So my question is why this blocking is required in read committed with snapshot isolation level?
I have several databases set to read committed snapshot isolation level. Tempdb is configured according to best practices, but I don't see it's used much.
The application uses EF6, and it calls the stored procedures in the following way
Hi everybody,I am using SQL Server 2005. I have a table which currently has only 1 record. I am unable to update any field for this particular record and SQL server is timing out and giving an error message saying No row was updated.

I am unable to update any field only for the 1 record in the table using my application, query window sql statement as well as directly changing the in the database.Can anybody please help me.thanks in advance,Murthy here

Hi I am new to visual studio and I am attempting to edit records held in mysql, the code below runs and throws no errors "strAdd" is underlined and says that it is used before it has been given a value! But If I debug.print(strAdd) I get the expected string returned. What do I need to do to get the updated records saved?
' code
Dim cn As ADODB.Connection Dim rs As ADODB.Recordset Dim StrAdd as string
cn = New ADODB.Connection cn.ConnectionString = "Provider=SQLNCLI;" _ & "Server=(local);" _ & "Database=customerlink;" _ & "Integrated Security=SSPI;" _ & "DataTypeCompatibility=80;" _ & "MARS Connection=True;" Dim mySQL As String
mySQL = "SELECT *" & _ " FROM tblvsol" & _ " Where RevStatus = " & 0 & _ " And GeoCodeStatus = " & 1
cn.Open()

How do I tell an update query to do the update only to one row in the table, and if there s more than one row in the where clause, then not to do the update.
Something like this:
update top 1 set myCol='value' where searchCol='criteria'
I receive Error: 3967, Severity: 17, State: 1. Insufficient space in tempdb to hold row versions. We have 8 data files for temp db of 10210 GB size and given 10240 GB as max size.
As MS suggest to calculate the temp db file size and growth rate we need to monitor the perform counters Free Space in Tempdb (KB) and Version Store Size (KB) in the Transactions object.
basic formula: [Size of Version Store] = 2 * [Version store data generated per minute] * [Longest running time (minutes) of your transaction
My report disk utilizations says tempdb is full ? I thonk I need a shrink for the file .
Still I am confused in calculating the size , My perform counter gives me data as such
Free Space in tempdb (KB)              279938496 Version Generation rate (KB/s)          53681040 Version Cleanup rate (KB/s)      53422320 Version Store Size (KB)     258720 Version Store unit count      22 Version Store unit creation                     774 Version Store unit truncation        752
After I watch a video for how to create MS SQL Replication, I configure distribution and create the publication. The problem comes from subscription. If I create a "PUSH" subscription, it works fine. However, when I create a "PULL" subscription, I got the following error. Where I should look for solution for this error.
I was stuck when update database using SqlDataAdapter. I have several textboxes in my webform1. When wepform1 is loaded, they will display user's information. The user can only input content in two textboxes. When user clicks the update button, I hope to update this record in SQL Server 2000 database. However, the program didn't work. There was no error message reported but when I stepped into the code, I found out that dataadapter's update method didn't succeed. I got 0 rows affected. Can I get some advice from someone ?
Here is the code:
string StrUpdateCmd = "Update Table1 Set Hphone = @Hphone, Cphone = @Cphone, Team = @Team Where emailname =@emailname ";
SqlDataAdapter UpdateDa = new SqlDataAdapter("Select * from Table1",SqlConnection1); UpdateDa.UpdateCommand = new SqlCommand(StrUpdateCmd, SqlConnection1);
//Update database int ret =UpdateDa.Update(dataset2,"Table1"); if( ret == 1 ) { ShowMessage("Update succeed!"); } else { ShowMessage("There is an error in updating "); }
Can anyone help with an effective way in retriving the id of the new record before input of any data into a form. We have a form where a few of the controls recordsource requires the new record id before they will display correctly. I have tried various ways to trigger the form afterupdate event in the hope that the id will be returned but get the error message "The data will be added to the database but the data won't be displayed in the form because it doesn't satisfy the criteria in the underlying recordsource"
here is my trigger that i have right now the only problem is that it deletes the records before copying everything into the db i dont what do delete everything i just whant to catch the updated record and then update the other tables same record in the other db how would i do this:
right now i have this
CREATE TRIGGER test ON [dbo].[TEST123] AFTER INSERT, UPDATE, DELETE AS IF @@ROWCOUNT = 0 RETURN
IF (COLUMNS_UPDATED() & 2 = 2) DELETE FROM pubs..TEST123 WHERE test3 = '300' INSERT INTO pubs..TEST123 SELECT * FROM TEST123 WHERE test3 = '300' UPDATE pubs..TEST123 SET test1 = 'X' WHERE test1 IS NULL AND test3 = '300' UPDATE pubs..TEST123 SET test2 = 'X' WHERE test2 IS NULL AND test3 = '300' UPDATE pubs..TEST123 SET test3 = 'X'

I want to Update one of the duplicate row as I don't have any unique id column. So can anybody update one of the the duplicate record without using any id or altering any column.
Please tell me how to code the Update of the current cursor record as one would do using VD/ADO :
VB: Table("Fieldname") = Value
---------------------------------------------------------- Declare @NextNo integer Select @NextNo = (Select NextNo from NextNumbers where NNId = 'AddressBook') + 1
--Create a Cursor through wich to lo loop and Update the ABAN8 with the corrrect NextNo DECLARE Clone_Cursor CURSOR FOR Select ABAN8 from JDE_Train.trndta.F0101_Clone Open Clone_Cursor Fetch Next from Clone_Cursor WHILE @@FETCH_STATUS = 0 BEGIN Select @NextNo = @NextNo + 1 Clone_Cursor("ABAN8") = @NextNo Update Clone_Cursor FETCH NEXT FROM Clone_Cursor END
Using trigger want to update a field being inserted from another record in the same table.
the record being inserted I want to pull the bkjrcode from another record where the account = 1040 that also has the same ord# and inv# as the record being inserted.
Here is what I've tried with no luck.
create trigger [updategbkmut] on [dbo].[gbkmut] after insert as
update g1 set g1.bkjrcode = g2.bkjrcode from gbkmut g1 inner join inserted i on i.ord_no = g1.ord_no and i.inv_no = g1.inv_no inner join gbkmut g2 on i.ord_no = g2.ord_no and i.inv_no = g2.inv_no where i.freefield3 = 'Rebate' and g1.account = '1040'
We are developing a database in SQL and we are trialing some of our typical analysis undertaken on out dataset.
I have a problem with a update function. ID direction Holiday Lat Long Speed obstime - Datestamp LicenseID - varchar(7) status - int (0 or 1) O-Unoccipied, 1-occupied Pickup - Boolean Dropoff - Boolean
I am trying to update the 'Pickup' or 'Dropoff' when the status changes from 0 to 1 or from 1 to 0 if the difference in the datestamp is less than 2 minutes. Pickup is when the status goes from 0 to 1 Drop off is when the status goes from 1 to 0
I have a form that depending on the outcome, will either add, update or delete a record.
1) If there IS NO record of "this" and "that" and Request("x") <> "" it will add a new record.
2) If there IS a record for "this" and "that" and Request("x") <> "" it will update column 1,2,3 or 4.
3) If there is a record for "this" and "that" and Request("x") = "" it will delete the record.
My problem is if there is a value in request("1") it works fine, but if there is no value in ("1") and there is a value in 2, 3, or 4 it will delete the record.
If request("1") <> "" OR request("2") <> "" OR request("3") <> "" OR request("4") <> "" Then
sSQL = "SELECT * FROM some_column WHERE this = '" & request("this) & "' and that = '" & request("that) & "'" oRS.Open sSQL,oConn,adOpenKeySet,adLockOptimistic If oRS.EOF Then oRS.Addnew oRS.Fields("this") = request("this") ors.Fields("that") = request("that") Else ors.Movefirst End If oRS.fields("1") = request("1") oRS.fields("2") = request("2") oRS.fields("3") = request("3") oRS.fields("4") = request("4") oRS.Update oRS.Close
Else
sSQL = "Delete from some_table Where this = '" & '" & request("this) & "' & "' AND that = '" & '" & request("that) & "' & "'" objCmd.ActiveConnection = oConn objCmd.CommandType = adCmdText objCmd.CommandText = sSQL objCmd.Execute
Hello All,I have 2 tables in a MS SQL DB. Table1 and Table2.LogTable2.Log was a copy of Table1 + an extra column for date_deleted. Ihave 2 Triggers on Table1, Insert and delete.

So if acertain field (not primary key) is updated for a record it is alsoupdated in Table2.log This way Table2.log will always have exactly thesame fields per record as Table1.I'm not sure how to reference the modified records only and updatejust the modified fields...something like...?----------------------------CREATE TRIGGER [tr_updateT_Log] ON [dbo].Table1FOR UPDATEASUpdate Table2.LogSET description = , office =-------------------------------------------------Any help would be greatly appreciatedThanksY
