I am having trouble getting an Update call to actually update records. The select statement is a stored procedure which is uses inner joins to link to property tables. The update, insert, and delete commands were generated by Visual Studio and only affect the primary table. So, to provide a simple example, I have a customer table with UID, Name, and LanguageID and a seperate table with LanguageID and LanguageDescription. The stored procedure can be used to populate a datagrid with all results (this works). The stored procedure also populates an edit page with one UID (this works). After the edit is completed, I attempt to update the dataset, which only has one row at this time, which shows that it has been modified. The Update modifies 0 rows and raises no exceptions. Is this because the update, insert, and delete statements do not match up one-to-one with the dataset? If so, what are my choices?
Hi, I am populating a datagrid with data from one sql table, I add additional columns and then wish to write it back out to another table. I have written the following code to acheive this, however it keeps throwing the follwing exception - "Update requites a valid UpdateComman when passed a DataRow collection with modified rows" I've looked and I can see what the problem is, can anybody help please? Private Sub FillData() 'SQL connection Me.sqlconnection = New System.Data.SqlClient.SqlConnection Me.sqlconnection.ConnectionString = ConfigurationSettings.AppSettings("CuroConnection")
Dim sql As String If Request("action") = "gen" Then sql = "select item from tblPickList where GroupName = 'xxx'AND Category = '" & Category2 & "' ORDER BY item ASC" ElseIf Request("action") = "fav" Then sql = "select identifiertext as item from tblfavourites where HRID = " & Session("hrid") & " and type = 3 ORDER BY identifiertext ASC" ElseIf Request("action") = "spec" Then sql = "select item from tblPickList where GroupName = '" & GroupID & "' AND Category = '" & Category2 & "' ORDER BY item ASC" End If
ds = New DataSet da = New SqlClient.SqlDataAdapter(sql, sqlconnection)
Try sqlconnection.Open() da.Fill(ds, "tblPickListTemp") sqlconnection.Close() Catch ex As Exception sqlconnection.Close() End Try
ds.Tables(0).Columns.Add("HRID") ds.Tables(0).Columns.Add("Flag") 'may possibly add a favourites column here at a later date to ensure no duplication
Dim dr As DataRow For Each dr In ds.Tables("tblPickListTemp").Rows dr("HRID") = Session("hrid") dr("Flag") = 0 Next
DgrdFavourites.DataSource = ds DgrdFavourites.DataBind() End Sub
Public Sub CreateTempRecords()

sqlcommand.Parameters.Add("@Item", "Item") sqlcommand.Parameters.Add("@HRID", "HRID") sqlcommand.Parameters.Add("@Flag", "Flag") da.InsertCommand = sqlcommand da.Update(ds.Tables(0)) End Sub
this does not work, it does work however if i replace the Me.textboxhello.Text with a value in quotation marks or with another text box not linked to that feild in the table... it does not work with the relevant text box!!!!!!!!
Hy, again! I am at the begining of an application. I have some modules that insert, delete and update only one row at one table. My question is should I use dataadapter.Update() or ExecuteNonQuery(). I prefer ExecuteNonQuery because I want to build a class : DataLayer to implement my own InsertProcedure(), UpdateProcedure(),DeleteProcedure(). I want speed in my application, so which is the best: dataadapter.Update() OR ExecuteNonQuery(). Thank you!
I'm using DataAdapter.Update() to update data in a table. My question is; how do I create a trigger that works after the update has completely finished?
For example if my update adds 50 new rows to a table the trigger I've currently got fires after each new row that is added ie 50 times in total. Is it possible to get it to trigger after the last (ie 50th) row is added???
I am trying to insert data into 2 different tables. I am using dataadapter and dataset.
Protected Sub SubmitButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles SubmitButton.Click Call ConnectionString()
Dim insertSQL As New SqlCommand() insertSQL.Connection = sqlConn insertSQL.CommandText = "SELECT location.CountryName, location.CityName, location.BuildingName, location.FloorID, rooms.name, rooms.FloorID AS Expr1 FROM location INNER JOIN floors ON location.FloorID = floors.id INNER JOIN rooms ON floors.id = rooms.FloorID"
Dim ds As New DataSet() Dim da As New SqlDataAdapter()
da.SelectCommand = insertSQL Dim scb As New SqlCommandBuilder(da)
Try da.Fill(ds) Dim ndr = ds.Tables("location").NewRow Dim ndr2 = ds.Tables("rooms").NewRow
My DataAdapter.Update() Method is running this query against my database and all the parameters and the formatting looks correct to me. I was wondering if anyone could identify obvious errors.... Thanks!
Is it possible to do an update on multiple records. I have fields CusOrderID and CusCreditAmt in table CusOrder; and fields CusOrderID and CreditAmt in table CusCredits. I would like to update the value in the CusCreditAmt field in CusOrder to equal the CreditAmt field in CusCredits where CusOrderID is the same in both tables.
I tried doing this in a stored procedure based on a View with an inner join between the 2 tables as follows:
Update View1 Set CusCreditAmt = CreditAmt
I received an error that the subquery returned more than one value. Is there anyway to do something like this and make it work?
I am trying to update a small subset of records of a given table (TRValue) using the records contained in ParcelTemp. The difficult part is getting the summation from a child file, TRGreen, for those same parcels contained in ParcelTemp. Instead of updating just a few records, all the records in TRValue are being updated, with the wrong values of course!
Basically, Update records in TRValue that are equal to:
Year = P.Year Code = 'LG01' Parcel = P.Parcel
with the summation of child records where the child records needed are:
Year = P.Year Parcel = P.Parcel
Code: UPDATE TRValue SET Acres = SumAcres, CurrentMarket = SumMarket, CurrentTaxable = SumTaxable, CurrentTaxAmt = ((SumTaxable * D.CertifiedRate) + 0.50) FROM ParcelTemp P
I have triggers in place on a table that do various checks on data input. It is clear that because of these triggers I cannot do updates on multiple records in this table. When I do, I receive an error that "subquery returned more than one value." Is there anyway to work around this by temporarily turning off triggers or something else?
I have a table that is increasing quite largely each day. By now, I have average 300 million of records over 2.5 years. Before we received our new interface, the data we received was aggregated and thus not that big.The problem is that the table is so huge that I cannot use the Slowly Changing Component. I was thinking about making a temp table where I load the incremental data before I load it into the final data mart table.Based on this temporary table I use a script to compare the temp data with the already existing data in the data mart. However, this requires a compare of each records (300 mil records).
Hi i am getting a weekly transaction file which has two columns trans code and trans date to indicate whether the record is changed, added or modified . and the monthly master file contains blank in these two fields.
How do i update the row coming from the transaction file in the tables which contain the rows from the master file .
to better explain the example is Master File
ID Name AGE Salary Transcode TransDate 2 dev 27 2777
Transaction File indicating change
ID Name AGE Salary Transcode TransDate 2 dev 27 24444 C 08072007
the ouput should be
2 dev 27 24444 C 08072007
replacing the existing row in the table(updating the whole row)
i have 50 columns in my table and based on the two fields i should replace the rows exisiting in table and if ID doesnot match exist just add them as a new row.
what transformation should i use .... to replace all the columns which have matching ID in table to the current record from trans file and if there doesnt exist matching id just add them as new row.
I have few tables. I want to identify the RECORDS for a table which has been created/modified for a particular date and time. I don't want to write a trigger to capture the event for add/update.
Is there any system table which track for date and time using stored procedure each individual records which has been last updated or newly created records??
Note : The application already created without lastModified date and each table... so, we don't want to modify the application or db.
I'm not a T-SQL expert so I'm calling on the pros. I want to design a stored procedure that updates only fields in a given record for which a non-null parameter is specified. Example: Create dbo.MySproc @CustomerID int, @CustomerFirstName varchar(50)=NULL, @CustomerLastName(50)=NULL AS UPDATE Customers SET CustomerFirstName= @CustomerFirstName , //update only if non-null CustomerLastName= @CustomerLastName //update only if non-null WHERE CustomerID = @CustomerID RETURN So say when calling sproc if @CustomerFirstName is specified but @CustomerLastName is not, the field CustomerFirstName would be updated but field CustomerLastName would retain original data. Thanx in advance!
I need a little help here..I want to transfer ONLY new records AND update any modified recordsfrom Oracle into SQL Server using DTS. How should I go about it?a) how do I use global variable to get max date.Where and what DTS task should I use to complete the job? Data DrivenQuery? Transform data task? How ? can u give me samples. Perhaps youcan email me the Demo Package as well.b) so far, what I did was,- I have datemodified field in my Oracle table so that I can comparewith datelastrun of my DTS package to get new records- records in Oracle having datemodified >Max(datelastrun), and transferto SQL Server table.Now, I am stuck as to where should I proceed - how can I transfer theserecords?Hope u can give me some lights. Thank you in advance.
Hi, What is the difference b/w sqldatareader and sqldataadapter? For what purpose are they used in a database connection & how do they differ from each other? Pls explain me in detail.Regards Vijay.
I have a project that consists of a SQL db with an Access front end as the user interface. Here is the structure of the table on which this question is based:
Code Block
create table #IncomeAndExpenseData ( recordID nvarchar(5)NOT NULL, itemID int NOT NULL, itemvalue decimal(18, 2) NULL, monthitemvalue decimal(18, 2) NULL ) The itemvalue field is where the user enters his/her numbers via Access. There is an IncomeAndExpenseCodes table as well which holds item information, including the itemID and entry unit of measure. Some itemIDs have an entry unit of measure of $/mo, while others are entered in terms of $/yr, others in %/yr.
For itemvalues of itemIDs with entry units of measure that are not $/mo a stored procedure performs calculations which converts them into numbers that has a unit of measure of $/mo and updates IncomeAndExpenseData putting these numbers in the monthitemvalue field. This stored procedure is written to only calculate values for monthitemvalue fields which are null in order to avoid recalculating every single row in the table.
If the user edits the itemvalue field there is a trigger on IncomeAndExpenseData which sets the monthitemvalue to null so the stored procedure recalculates the monthitemvalue for the changed rows. However, it appears this trigger is also setting monthitemvalue to null after the stored procedure updates the IncomeAndExpenseData table with the recalculated monthitemvalues, thus wiping out the answers.
How do I write a trigger that sets the monthitemvalue to null only when the user edits the itemvalue field, not when the stored procedure puts the recalculated monthitemvalue into the IncomeAndExpenseData table?
Why DataAdapter does NOT load relations from DB ?the relations are made using SQL SERVER MANAGEMENTbut when a fill a datatable using dataadapter the relations are not loaded .why ? what is the solution to this problem ?
Hi i'm a new to ASP.NET and for some reason when i click the Next button in the code below, the pageIndex does not change.

I have done some reading on the dataadapter class, but do not have a good handle on how to work with dataadapter after it has been filled by a dataset. For instance, should I use an if statement such as this to update the value in the dataadapter? if (dsSunbelt.Tables[0].Columns[39].Equals("")) { DataRow drUpdate = dsSunbelt.Tables[0].Columns[39].Equals(DateTime.Now); } I am sure it is not hard to see what I am doing, and I hope that I am missing something small, but how do I isolate a dataadapter value to update in the corresponding database?
I'm reading XML data into a DataTable that is populated into a datagrid. From here I need to update database and wanted to know how to Fill a DATA ADAPTER with a DATA TABLE? I'm familiar with updating using a SQL command, but in this case, i have the dataTable already created from XML. Please help. Thanks,

Good day, I just like to ask if anybody has experienced getting empty rows from SQL data adapter? I'm using SQL Server 2005. Problem is when the sql is run on Query Analyzer it retrieves a number of rows but when used in my application it returns 0 or empty rows. I thought the connection is not the problem since I got my columns right. Below is my code snippet. Thanks! const string COMMAND_TEXT = @"select distinct somefield as matchcode, count(somefield) " + "as recordcount from filteredaccount where StateCode = 0 group by somefield having count(somefield) > 1"; SqlDataAdapter adapter = new SqlDataAdapter(COMMAND_TEXT, connection); DataTable dt = new DataTable(sometablename); adapter.Fill(dt);
For some reason I've had trouble with this today... can anyone provide me with a generic code snippet that programatically allows me to select data from a database limited by a parameter and then fills a datatable?

I am reading multiple databases into a single dataset, putting each read into a new datatable in the set. Ultimately, I want to merge the multiple tables (they are all from different DB tables in different locations using the same schema). I am also combining this with data from an Oracle database which is in yet another table in the same dataset.
Here is my question:
I will not be propagating any changes to this data back to its original source, but I will be populating it out to Active Directory. (Don't worry; I'm not asking any AD questions here.) But I do want to run SELECT, DELETE, and UPDATE queries against the data in the dataset in memory without writing it out to a separate file. Based on that type of usage, would I be better to use a DataReader or a DataAdapter to do the read from the original database? If I use a DataReader, can I still update the data in memory? In either case, what's the correct methodology to update data in a dataset in memory?

I would like to update Table 1 with the data from Table 2. Here is my problem..Lets say that I have two records in Table 2 that have the same policyNumber but two different NewEmpNames, it only takes the first. In other words, a single policynumber can be moved to a New EmpName and then again later on to another NewEmpName adn even again if need be
I am trying to update a field within one table with the values from another table. With the criteria that another field in each table are equal. What is the correct way to do this. My syntax is all wrong.
I have table1 which has many unique ID numbers and table2 that has many records for each ID. some of the ID numbers in table1 have changed and I have created a translation table (table3) that links the old and new ID numbers.
What I need to do is some sort of update sql statement that updates all the records in table2 changing all the oldID numbers to the new ones using the translation table.
Table1 and table2 are not linked...can anyone help me with the sql statement
example
Table 1 IDNUM NAME 12345 Joe 12346 Mary 12347 David
