I have a code to update an access database from one of my dataset tables, but i want to insert columns manually
currently i am using this code to update my db
Dim cb As OleDb.OleDbCommandBuilder = New OleDb.OleDbCommandBuilder(dtadpt)
AccessConn.Open()
dtadpt.Update(DataSet, "recordsforupdate")
AccessConn.Close()
this code automatically inserts all the columns of dataset table to the access database table.
what i want is to inset the values for eg. in col4 of my dataset table into col5 of my access table, for that i want to manually use "inset into" statement to update the db table, but i am having problem with the syntax for using dataset..can anyone help please
Hi,Ive got a class in my code which contains data from several tables. A user profile has a single record in a user_profile tables, for each of these records there is several records in a another table, which itself has several records in a tags table.So far the save method on the class saves the record to the user profile table, then loops through the next two tables info to insert each record. I want to decrease the number of trips to the database and am wondering if anyone can advise on the best way to do this.I am considering using a dataset to retrieve and store the records, instead of a datareader Im using currently. Then when Im done altering the data in the dataset (all three tables) I can commit all the changes in one database transaction?? I have been avoiding datasets due to the fact datareaders are apparently faster.My other option is to try make three calls to the database, one per table, updating my stored procedures to accept arrays of data using XML?? Can anyone tell me what is the best option for me?Thanks,C
I am having the oddest problem. I can update the data in the dataset, but when I use the update command, or try to do a update manually it will not save the values back to the database.
tbl_strt_tmesTableAdapter.Update(lesson_plannerDataSet.tbl_strt_tmes);//this should save the values
}
catch (Exception e)
{
MessageBox.Show(e.Message);
}
}
the table adapter update, should send the values to the database, but for some reason, it is not. i can see the existing values from the database, along with my new values that i added in my loop, but those values are not being sent to the database when I invoke the update command on the data adapter.
Any help will be greatly appreciated. I am making this program for my wife who is a school teacher.
Hi, I have an application where I'm filling a dataset with values from a table. This table has no primary key. Then I iterate through each row of the dataset and I compute the value of one of the columns and then update that value in the dataset row. The problem I'm having is that when the database gets updated by the SqlDataAdapter.Update() method, the same value shows up under that column for all rows. I think my Update Command is not correct since I'm not specifying a where clause and hence it is using just the value lastly computed in the dataset to update the entire database. But I do not know how to specify a where clause for an update statement when I'm actually updating every row in the dataset. Basically I do not have an update parameter since all rows are meant to be updated. Any suggestions? SqlCommand snUpdate = conn.CreateCommand(); snUpdate.CommandType = CommandType.Text; snUpdate.CommandText = "Update TestTable set shipdate = @shipdate"; snUpdate.Parameters.Add("@shipdate", SqlDbType.Char, 10, "shipdate"); string jdate =""; for (int i = 0; i < ds.Tables[0].Rows.Count - 1; i++) { jdate = ds.Tables[0].Rows[i]["shipdate"].ToString(); ds.Tables[0].Rows[i]["shipdate"] = convertToNormalDate(jdate); } da.Update(ds, "Table1"); conn.Close();
Hi all,I am using a Strongly Typed DataSet (ASP.NET 2.0) to insert new data into a SQL Server 2000 database, types of some fields in db are nvarchar. All thing work fine except I can not insert unicode data(Vietnamese language) into db.I can't find where to put prefix N. Please help me!!!
Hi all, I'm trying to update various rows in my DB with a new value once an action occurs. I am using the following code which does not throw any exceptions, but also does not change the values. Can someone steer me in the right direction? public static void ChangeRefCode() { SqlConnection dbConn = new SqlConnection(ConnectDB.getConnectString()); SqlDataAdapter dataAdapt = new SqlDataAdapter("Select * from Posting",dbConn);
I am using ASP.NET 2.0 WebForms and I was trying to use a DataSet to add rows programatically without adding the actual records to the MS SQL Server Databases. Is this possible or should I be doing this another way? DataSet myDS = new DataSet();DataTable myTable = new DataTable("table1");myTable.Columns.Add("col1", typeof(string));myDS.Tables.Add(myTable);myTable.Rows.Add("MyValue"); Thanks.

I have a dataset that was created via a source + lookups + derived columns.
I wish to take this dataset and treat is as a table within a sql statement so that I can update a permanent table with the a specific value within the temp dataset.
In sql this is what I am trying to do:
SELECT COUNT(*) AS Count_of_Employees, DEPT FROM Employees GROUP BY DEPT
UPDATE Departments SET Number_of_Employees = Count_of_Employees WHERE Dept = dept.
i created a query to insert a row in DataSet in Visual Studio 2005. i gave the method name to the query i created. as i understood it returns '1' if successful or '0' if not.
I want to use SSIS in order to synchronize data. The OLEDB and ADO.NET Destination Adapter just inserts the rows read from the source. Since I have PK Constraint on destination, the tranform fails. How can I ask to update the records in destination DB?
I have a table adapter for one of my SQL2005 tables, and in two different fields I accept a date time. Now 99% of the times, new rows to this table will be filled out using DateTIme.Now(), as a Time Stamp is what I'm going for.
Here is the line of code in question...cops_current_data_adapter.Insert(ProductOrder, Convert.ToInt16(Session["StationId"].ToString()), PartNumber, DateTime.Now, DateTime.Now, Convert.ToInt16(qty), 0); The second DateTime.Now is the one that can be null, and it's throwing a formatting error everytime I try and drop it in there. It's a FormatException, and there's not much more to the example except unhelpful tips like be careful when conveting a string to a dateTime, which I'm not doing. Needless to say for the code to compile, and then throw a Format error at runtime is a bit frustraiting. Any suggestions would be most appreciated
Ok I think I will need to use a temp table for this and there is no code to share as of yet. Here is the intent.
I need to insert data into two tables (a header and detail table) the Header Table will give me lets say an order number and this order number needs to be placed on the corresponding detail lines in the detail table.
Now if I were inserting a single invoice with one or more detail lines EASY, just set @@Identity to a variable and do a second insert statement.
What is happening is I will be importing a ton of Invoice headers and inserting those into the header table. The details are already in the database across various tables and and I will do that insert based on a select with some joins. As stated I need to get the invoice number from IDENTITY of the header table for each DETAIL insert.
I am assuming the only way to do this is with a loop... Insert one header, get identity; Insert the detail table and include the IDENTITY variable, and repeat.
I have the following stored procedure that inserts records and updates the new record. The parameter @rpt_id has a value of -1 when entering the procedure. It needs to be updated with the new record if (identity) once the record is inserted, bu sometimes the update does not happen. The new records ends up with -1 in the rpt_id column.
I have included the stored procedure. I will appreciate any ideas?
I have 18 odd subscribers at the moment, my publisher and disttribution is on the same machine with push subscriptions.
The questions I have
nr 1. While trying to initialize new subscribers I get loads of deadlocks even after I stop dist cleanup agent. This *I think* cause some other unexpected problems.
nr2. The queue reader would fail saing it cannot find the "insert" proc on the publisher, although it exists. I have changed anything on the publication so I'm not sure how this happens or why.
nr3. I replicate a varbinary(max) column and on the odd occasion get the "Length of LOB data" errors which I then set with sp_configure. The catch here is that the length never exceeds a "len()" of 4000, thus the reported LOB and my calculation doesn't tie up.
I have my first small SQl Server 2005 database developed on my localserver and I have also its equivalent as an online database.I wish to update the local database (using and asp.net interface) andthen to upload the data (at least the amended data, but given thesmall size all data should be no trouble) to the online database.I think replication is the straight answer but I have no experience ofthis and I am wondering what else I might use which might be lesscomplicated. One solution is DTS (using SQL 2000 terms) but i am notsure if I can set this up (1) to overwrite existing tables and (2) notto seemingly remove identity attributes from fields set as identities.I know there are other possibilities but I would be glad of advice asto the likely best method for a small database updated perhaps onceweekly or at less frequent intervals,Best wishes, John Morgan
How do I insert data that I have collected in a local database onto a table on my online ie hosted database which is on a different server?
At the moment I am just uploading all the data to the hosted DB but this is wasting bandwith as only a small percentage of data is actually selected and used.
I thought that if i used a local DB and then update the table on my hosted DB this would be much more efficient, but I am not sure how to write the SQL code to do this!
I got thrown into a new project that is going to require me to update an SQL server database tables from an Access table on the backend of an Oracle database on another server. At the end of each day the Access dabase will be updated from the Oracle database.
What I need to do, is when the Access database is updated I need to have the table in the SQL database automaticaly updated. When a new record is added to the Access table I need the new record added to the SQL table. When a record is deleted in the Access table I need to keep that record in the SQL table and set a field to a value (such as 0). And when a record is updated in Access, have it updated in SQL.
Needless to say this is a bit out of my area and not sure how to accomplish this.
i have sql 2005 installed on my personal machine, but our server has sql 2000 on it. the structure of my database was made on the server, but i'm not sure how to update the server copy from my local copy. when i try to export my data from my local machine to the server (or import from my local machine to the server), i get pre-execute errors.
roughly every other week, i'll need to be able to update the server version from my local version, so i'm trying to find the most efficient method. what is the best way to update a 2000 database from a 2005 database? it doesn't matter if i append or overwrite, but i do use identity fields. the error i get when trying to use the import/export wizard is:
- Pre-execute (Error)

I have a report with multiple datasets, the first of which pulls in data based on user entered parameters (sales date range and property use codes). Dataset1 pulls property id's and other sales data from a table (2014_COST) based on the user's parameters. I have set up another table (AUDITS) that I would like to use in dataset6. This table has 3 columns (Property ID's, Sales Price and Sales Date). I would like for dataset6 to pull the Property ID's that are NOT contained in the results from dataset1. In other words, I'd like the results of dataset6 to show me the property id's that are contained in the AUDITS table but which are not being pulled into dataset1. Both tables are in the same database.
I have a small number of rows in a dataset, Table 1. There is a CLOB on a large dataset, Table 2. They join on a PK. I would like to retrieve this CLOB and add it to the data flow for Table1. In short I want to emulate the following:
Table 1: Small table without CLOB, 10 rows. Table 2: Large table with CLOB, 10,000,000 rows
select CLOB from table2 where pk = (select pk from table1)
I want this to return the CLOBs for the small number of rows in Table 1. The PK is indexed obviously so it should be a fast look up.
Table 1 and Table 2 live on different Oracle databases. How do I perform this operation efficiently in SSIS? It seems the Lookup and Merge Join wont do this.

I found out the data I need for my SQL Report is already defined in a dynamic dataset on another web service. Is there a way to use web services to call another web service to get the dataset I need to generate a report? Examples would help if you have any, thanks for looking
I'm new at this so I apologize in advance for my ignorance.
I'm creating a website that collects dates in a calendar control (from Peter Blum). When the page containing the control loads it populates the calendar with dates from the database (that have previously been selected by the user). The user then can delete existing dates and/or add new dates.
I create a dataset when the page loads and use it to populate the calendar. When the user finishes adding and deleting dates in the calendar control I delete the original dates from the dataset and then write the new dates to the dataset. I then give execute the data adapter update command to load the contents of the dataset back into the database. This command involves using parameterized queries. For example the Insert command is:
Dim cmdInsert As SqlCommand = New SqlCommand("INSERT INTO Requests VALUES(@fkPlayerIDNumber, @RequestDate, @PostDate, @fkGroupID)", conn)
Appreciate your efforts in answering queries of so many newbees!I hope to find answering my query..I have created a logon screen to which i have also given the option of changing the password ... Now below is the code for updating the new password given by the user ....Imports System.Data.SqlClient Dim con As New SqlConnection("server=sys2;initial catalog=kris;integrated security=SSPI") Dim cmd As New SqlCommand("select * from u_login", con) Dim dr As SqlDataReader Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load End Sub Private Sub btnUpdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click con.Open() dr = cmd.ExecuteReader While dr.Read() If dr(0) = txtEmail.Text And dr(1) = txtoldpwd.Text Then Dim NewPwdStr As String = txtnewpwd.Text Dim OldPwdStr As String = txtoldpwd.Text Dim sqlstr As String = "Update U_Login set pwd = ('" & NewPwdStr & "') Where pwd = '" & OldPwdStr & "'" Dim cmd1 As New SqlCommand("sqlstr", con) cmd1.ExecuteNonQuery() Response.Write(" Password Changed ... Please login again") End If End While dr.Close() con.Close() End Sub The above code although doesnt throw any error however it shows a blank screen and doesnt even update the new password. Can you plz help me understand what could possibly be wrong in my code n why is that am getting the blank screen. Your help will be highly appreciated!Thanks,Brandy

At present I am working on a school project. the project was installed few months back. database is MSsql server. Because of some new things i had to change few tables, add few columns and add few tables also. Now My problem is that the school is already having the data which they don't want to be disturbed . So I want My structure and their data.
I'm having a difficult time calling UPDATE when my 'WHERE" clause calls ID,which is numeric and the primary key. I found that I can do a SELECT justfine with "WHERE ID"..
