Hi all, I'm new to SQL and have been trying to update a record in a table, something I imagine would be quite simple. The record holds a INT value and I wish to test the value to see if it is greater than 70, if it is....reset the value to 1
I have tried various methods, aiming at using a stored procedure that will run once a day at midnight.
The process of adding a column with DEFAULT (0) to a table that has 15million records takes a despicable amount of time (too much time) and the transaction log of the database grew to an unacceptable size. I would like to accomplish the same task using this procedure:
·Add the column to the table with null value. ·Loop through the table (500000 records at a time) and SET the value in the newly added column to 0. ·Issue a commit statement after each batch ·Issue a checkpoint statement after each batch. ·Alter the table and SET the column to NOT Null DEFAULT (0)
Here is my Sample script
ALTER TABLE EMPLOYEE ADD EZEVALUE NUMERIC (9,6) NULL Go
Loop UPDATE EMPLOYEE SET EZEVALUE = 0 Commit Tan CHECKPOINT END (Repeat the loop until the rows in EMPLOYEE have the value 0)
Go
ALTER TABLE EMPLOYEE ALTER COLUMN EZEVALUE NUMERIC (9,6) NOT NULL DEFAULT (0)
My problem is with the loop section of this script. How do I structure the loop section of this script to loop through the employee table and update the EZEVALUE column 500000 rows at a time, issue a Commit Tran and a CHECKPOINT statement until the whole table has been updated. Does anyone out there know how to accomplish this task? Any information would be greatly appreciated.
We're running a Sage CRM install with a SQL Server 2000 database at the back end. We're using the Sage web services API for updating data and a JDBC connection to retrieve data as it's so much quicker.
If I retrieve a record using the JDBC connection and then try and update the same record through the web services, the query times out as if the record is locked for updates. Has anyone experienced anything similar or know what I'm doing wrong? If I just use DriverManager.getConnection() to establish the connection instead of the datasource, and then continue with the same code I don't get these record locking problems. Please find more details below.
Thanks, Sarah
The JDBC provider for the datasource is a WebSphere embedded ConnectJDBC for SQL Server DataSource, using an implementation type of 'connection pool datasource'. We are using a container managed J2C authentication alias for logging on.
This is running on a Websphere Application Server v6.1.
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.
Hello I need an alarm or raise an event from SQL Server after updating to get it in .net. I use SQL Server 2005 Express Edition and vb.net2 for my programming language. Suppose that in a windows form I have a grid and I'm working with this page another client is working with this same page .He is editing the information of a record of a grid and save it in database so I want to give an alarm or an event that raise from SQL Server (for example in a trigger) , what can I do? Thanks.
Hi, I have a problem, it is that when I try to update a record in my SQL server database, it is not updated and I recieve no error messages. This is the code behind the update button. The stored procedure is "sqlupdate".
Code Snippet
Dim ListingID As String = Request.QueryString("id").ToString Dim con As New SqlConnection(ListingConnection) Dim cmd As New SqlCommand("sqlupdate", con) cmd.CommandType = CommandType.StoredProcedure Dim id As SqlParameter = cmd.Parameters.Add("@id", SqlDbType.UniqueIdentifier) id.Direction = ParameterDirection.Input id.Value = ListingID
Dim PlaceName As SqlParameter = cmd.Parameters.Add("@PlaceName", SqlDbType.VarChar) PlaceName.Direction = ParameterDirection.Input PlaceName.Value = PlaceNameTB.Text

I'm using VB.Net 2008 with SQL Compact 3.5. After trying forever, I finally got my app to open a retrieve a record from a table. Now, when I try to update the record, I get an error on the ExecuteNonQuery statement. The error says I am "attempting to read or write protected memory". The code works perfectly with an Access database.
Hello, i currently have a gridview component displaying data from a SQLSERVER2005 database. I have created an 'edit' hyperlink on each record so that when pressed, the primary key of a record is sent in the querystring to another page when pressed. example http://localhost/Prog/EditAppointment.aspx?AppointmentId=1 In the edit page, i have dragged and dropped a sqldatasource that contains the select and update statements. i would now like to use textboxes and dropdowns to display the data for the particular record selected (in this case appointmentid=1). however i dont want to use a formview or automated component, just to drag and drop the textboxes myself. how do i bind the textboxes in the HTML code to the data from the select statement? My current select parameters look as follows. <SelectParameters> <asp:QueryStringParameter Name="AppointmentId" QueryStringField="AppointmentId" Type="Int32" /> <asp:ControlParameter ControlID="Textbox1" Name="PatientNo" PropertyName="Text" Type="String" /> </SelectParameters> Perhaps there is an error in my select parameters or does the problem lay elsewhere? Any help would be appreicated. Thanks, James.
Hi People, hope someone can help me out here with a little problem. Basically i've go a asp.net page which has a listbox on. This list box is populated from a SQL database table with the datetime of the a selected field. Thus in the list box you get a list of strings looking like this "24/09/07 12:58" Also on the page is a submit button, and some other editing textboxes. The main issue here is the when the submit button is used i get the currently selected listbox timedate string and then pass this along with other items to update a record in the database based on the datetime in the listbox control.
Below is how i get the string from the listbox control Dim except_time As DateTime except_time = DropDownList1.SelectedValue The expect_time is then passed to store procedure along with some other vars, which looks like this -- =============================================-- Author: Lee Trueman-- Create date: 1st Sept 2007-- =============================================CREATE PROCEDURE [dbo].[spExcept_UpdateData] -- Add the parameters for the stored procedure here @validated bit, @update_time datetime, @except_time datetimeASBEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON -- Insert statements for procedure here UPDATE exceptions SET validated = @validated, update_time = @update_time WHERE (except_time = @except_time)END So validated and update_time should be updated when except_time is equal to @except_time
My problem is that the database never updates. If i debug the asp.net page the watch var shows the datetime in US format (I.e "09/24/07 12:58"), if this is true then this would explain why when it is passed to the stored proc nothing gets updated, as there would not be a date match. can anyone see any silly mistakes i'm doing here ????
I am trying to write a stored procedure that updates a value in a table based on the sort order. For example, my table has a field "OfferAmount". When this field is updated, I need to resort the records and update the "CurrRank" field with values 1 through whatever. As per my question marks below, I am not sure how to do this.
Update CurrRank = ??? from tblAppKitOffers where appkitid = 3 AND (OfferStatusCode = 'O' OR OfferStatusCODE = 'D') ORDER BY tblAppKitOffers.OfferAmount Desc
Hi, I need help with updating a record. When I run the following code underneath the update button, the record does not update and I get no error message. Anyone have any ideas?
Code Snippet

I created a package in SSIS to export data from mutiple SQL server tables to a single flat file. Once the export is completed i need to update 2 tables ( a batch table and a history table) In the batch table I need to insert a record with batch # (system generated),batch date, status( success/failed), record count( no of records in the flat file), batch filename). In the history table, i need to insert a record for each of the rows in the flat file with the foll info. batch number,datetime,status(success/failed)
My question is how do I get the batch status,record count, batchfilename for batch table update and how do i get to update the history table.
BTW, i am executing this package as a SQL Server Agent job. I am new to Integration Services and feel lost. Any help ?
I am currently using VC++/Cli 2005. In a project, I'm using a DataGridView control to show records from a SQL Express 2005 table. Instead of updating a specific item directly within DataGridView control, I would like to open a new form and allow user to update selected record/item within that form. The reason to update this way is conditionned by the fact that I have 3 levels of detail as following:
Level 0 Level 1 Level 2
1:N 1:N Furniture --> Component --> Component
You all understand that update form of Level1 will/must include, as Level0 do, another DataGridView control to display/detail all related items issued from next level. This explains why I can't allow user to update Level 1 directly from DataGridView control.
I've searched in MSDN and even bought a few books on subject but unfortunately I found nothing on how to do it this way. All articles on DataGridView control were only showing how to update record directly from control.
My approach, I think, would be to transmit to my level1 updating form, as a single parameter, the selected DataRow object (or a brand new one if currently adding) issued from DataGridView and let user update it's content. When User finally leaves level0 update form, then I presume that DataGridView corresponding table would be automatically updated according to DataGridView's content.
What would be the proper way to do it? I would certainly appreciate to hear you view on this.
Also, what can I do if I want to refresh DataGridView's content when coming back from update form. Is it done automatically? I would certainly be sure that it reflects the reality, not only when I update it myself but also especially when other users could concurrently update same records?
HI all, I have a windows application which runs a process,
I am updating database column "Status" with Processing when the application is running, and on completion I update it with Staus="Completed" or in case I close the application I update db with Status="Interupted" .
I have problem that in case while proces is running, power supply or system turns off, the db Status="Processing", but in actual it is interupted. How will i update?
Inside a single transaction I'm inserting/updating multiple records into multiple tables, in this order: table 1 record 1 table 2 record 1 table 3 record 1 table 1 record 2 table 2 record 1 table 1 record 3 table 2 record 3 table 3 record 3
Now I'm getting an unspecified error on a certain table:
Indicates a data modification, such as an insert, an update, or a deletion. Ensures that multiple updates cannot be made to the same resource at the same time. (I assume that multiple updates within the SAME transaction can be made, only multiple updates from different transaction cannot be made, right?) I cannot find any reference to this error message and don't know what the numbers mean. Maybe it relates to data that can be found in the sys.lock_information table like explained here, http://technet.microsoft.com/en-us/library/ms172932.aspx, but I'm not sure.
Furthermore, the sys.lock_information table is empty. I haven't been able to reproduce the problem myself. I only received an error log and the database to investigate it.
So, does anybody have an idea what this error message means and what I can do to troubleshoot this?
Hi I have a table with a user column and other columns. User column id the primary key.
I want to create a copy of the record where the user="user1" and insert that copy in the same table in a new created record. But I want the new record to have a value of "user2" in the user column instead of "user1" since it's a primary key
Is that possible to restrict inserting the record if record already exist in the table.
Scenario: query should be
We are inserting a bulk information of data, it should not insert the row if it already exist in the table. excluding that it should insert the other rows.
Hi All,I have a table in SQL Server 2000 that contains several million memberids. Some of these member ids are duplicated in the table, and eachrecord is tagged with a 1 or a 2 in [recsrc] to indicate where theycame from.I want to remove all member ids records from the table that have arecsrc of 1 where the same member id also exists in the table with arecsrc of 2.So, if the member id has a recsrc of 1, and no other record exists inthe table with the same member id and a recsrc of 2, I want it leftuntouched.So, in a theortetical dataset of member id and recsrc:0001, 10002, 20001, 20003, 10004, 2I am looking to only delete the first record, because it has a recsrcof 1 and there is another record in the table with the same member idand a recsrc of 2.I'd very much appreciate it if someone could help me achieve this!Much warmth,Murray
I'm inserting from TempAccrual to VacationAccrual . It works nicely, however if I run this script again it will insert the same values again in VacationAccrual. How do I block that? IF there is a small change in one of the column in TempAccrual then allow insert. Here is my query
INSERT INTO vacationaccrual (empno, accrued_vacation, accrued_sick_effective_date, accrued_sick, import_date)
From last 1 week or so, i have been facing very strange problem with my sql server 2005s database which is configured and set on the hosting web server. Right now for managing my sql server 2005 database, i am using an web based Control Panel developed by my hosting company.
Problem i am facing is that, whenever i try to modify (i.e. add new columns) tables in the database, it gives me error saying that,
"There is already an object named 'PK_xxx_Temp' in the database. Could not create constraint. See previous errors. Source: .Net SqlClient Data Provider".
where xxx is the table name.
I have done quite a bit research on the problem and have also searched on the net for solution but still the problem persist.
Hi All, I have a Problem while updating one table data from another table's data using sql server 2000. I have 2 tables named TableA(PID,SID,MinForms) , TableB(PID,SID,MinForms) I need to update TableA with TableB's data using a single query that i have including in a stored procedure.
Im trying to create an update statement which references two tables (join) and has a CASE clause attached. Not sure where im going wrong...
Using T-sql!!!
update import set import.gone = from import inner join stat ON stat.id = import.id CASE WHEN stat.A = import.field2 THEN import.gone = sec.A WHEN stat.B = import.field2 THEN import.gone = sec.B WHEN stat.C = import.field2 THEN import.gone = sec.C WHEN stat.D = import.field2 THEN import.gone = sec.D WHEN stat.E = import.field2 THEN import.gone = sec.E WHEN stat.F = import.field2 THEN import.gone = sec.F ELSE import.gone = null END
I am trying to update a table in one database with data from a temporary table which i created in the tempdb.
I want to update field1 in the table with the tempfield1 from the #temp_table
The code looks something like this:
Use master UPDATE [dbname].dbo.table SET [dbname].dbo.table.field1 = [tempdb].dbo.#temp_table.tempfield1 WHERE ( [dbname].dbo.table.field2= [tempdb].dbo.#temp_table.tempfield2 AND [dbname].dbo.table.field3= [tempdb].dbo.#temp_table.tempfield3 AND [dbname].dbo.table.field4= [tempdb].dbo.#temp_table.tempfield4)
I get the following error: Msg 4104, Level 16, State 1, Line 2 The multi-part identifier "tempdb.dbo.#temp_table.tempfield2" could not be bound. Msg 4104, Level 16, State 1, Line 2 The multi-part identifier "tempdb.dbo.#temp_table.tempfield3" could not be bound. Msg 4104, Level 16, State 1, Line 2 The multi-part identifier "tempdb.dbo.#temp_table.tempfield4" could not be bound.
Hi... I was hoping if someone could share me some thoughts with the issue that I am having at the moment.
Problem: When I run the package in my local machine and update local SS DB/table - new records writes OK in the table. BUT when I changed my destination meaning write record into another physical SS DB/table there is no INSERT data occurs. AND SO when I move/copy over that same package into another server (e.g. server that do not write record earlier) and run it locally IT WORKS fine too.
What I am trying to do is very simple - Add new records in a SS table using SSIS . I only care for new rows and not even changed rows. Here is my logic - 1. Create Ole DB source to RemoteSERVER - using SELECT stmt 2. I have LoopUp component that will look for NEW records - Directs all rows that don't find match and redirect rows (error output). 3. Since I don't care for any rows that is matched in my lookup - I do nothing or I trash the rows 4. I send the error rows (NEW rows) into OleDB destination
RESULTS when I run the package locally and destination table is also local - WORKS FINE; But when I run the package locally and destination table is in another Sserver (remote) - now rows is written.
The package is run thru BIDS manually so there is no sucurity restrictions attached to it.
I am not sure what I am missing. And I do not see error in my package either. It is not failing.
In SQL Server 2000, I have a parent table with a cascade update to a child table. I want to add a record to the child table whenever I add a table to the parent table. Thanks
I would like to find out how to capture record count for a table in oracle using SSIS and then writing that value in a SQL Server table.
I understand that I can use a variable to accomplish this task. Well first issue I run into is that what import statement do I need to use in the design script section of Script Task. I see that in many examples following statement is used for SQL Server databases:
Imports System.Data.SqlClient
Which Import statement I need to use to for Oracle database. I am using a OLE DB Connection.
