everything works fine. The column PURPOSE does exist and I am able to INSERT information into the PURPOSE column.
An unhandled exception of type 'System.InvalidOperationException' occurred in system.windows.forms.dllerror in line: dbAdp.Update(dbDset) in btnSave_Click, (elseif editflag = true) blockdescription: Update unable to find TableMapping['Table'] or DataTable 'Table'I was also wondering if I could simply use the ExecuteNonQuery for the delete statement, but since I've placed my data in a datarow, I'm not sure if i can actually use it. Any thoughts on this? Btw, this is my first time using a datarow, and I've recently been studying how to use ADO.net.
dr = dbDset.Tables(0).Rows(CurIndex)
dr.Delete()
dbAdp.Update(dbDset.Tables("addresses"))

Im trying to add columns to my database through VB.NET. I have a MS Access database (MDB format). It has a table in it called "TestTable" and that table has only one field in it "FirstField". It has no data in it yet. I want to add columns to it first and then fill data.

if a call to For Each starts by calling the Enumerator's MoveNext, then Current, then MoveNext, then Current, and so on until MoveNext returns a False then it exits, am i right to say that the Reset is never called?initially i thought that Reset would be called when MoveNext returns False, i tried this (a msgbox would come if it was ever called but i got no msgbox at all)
[code]...
if that's the case, what exactly is the use of the reset in an ienumerator, and is it ok to leave it empty, as such
Attempting to run an SQL statement to UPDATE a column in a table with new data. The column being updated is defined as varchar(40) and the new data is 41 bytes (varchar(41)). I get a generic 'data will be truncated' error message, but no detail on which column caused the problem. I've attached a sample VB program to illustrate the issue. In this scenario, Company is defined as varchar(40).
My question: Can I get a more detailed error message? i.e. can I get an error message that tells me the row and column that the truncation occurs in? Often times, I may be updating hundreds or thousands of rows and only one value in one column from the source file is too large for a database cell. As a related question, does each OLEDB provider create its own error messages. i.e. will the MS SQL Server OLEDB provider potentially give different text in the error message than say the MS Jet OLEDB provider?

Below code is supposed to update a table in oracle with rows imported. But it seems to update all columns in the table with only the first column which is imported from the CSV file. I figure its the "ReadFields" property which needs to manipulated/changed.

I have a gridview loaded with data from my database and a gridview swapping function which after exchanging data between rows with a column call "Priority", I want to save these changes back to my database. Only the "Priority" column value will be change, how do I update only that Column of my dataset table to my SQL database?

As the title says, when I attempt to update a row in a table in a database, I recieve an InvalidCastException. I am unsure why, since the variables I am using should be, and indeed, when I check them at runtime, are filled with the correct data.
I am trying to update using the method wherein the row that is being updated is identified with all the variables already stored. Interestingly, Intellisense is telling me that EntryID, the primary key, is only necessary in it's original form, and that the variables that I am attempting to update have question marks after their type.
I am looking for the best way to edit and update the value of a database column that is defined as data type TEXT. You can't use a replace command in SQL and if I read in the value, update the data and update the record, the changes are not applied.
View 3 RepliesI want to Update Column of a Table where ColumnName will be DropDown.SelectedValue.Example: A set of RECORDS will be displayed from a Customer Table where CUstNo ='1234' and City= 'Chicago' and Grade ='B' Once displayed I want to Update the grade to 'A' of all those customers from the above criteria. In My case I have like 100 Columns, so in where Clause Column Names will be selected from a DaropDown.In My Query, Update Customer SET ColumnName= 'some value' where ColumnName ='ActualValue'So how can I pass the ColumnName which is Dropdown Selected Value. I believe I can't give as Update Customer SET DropDown.SelectedValue = 'some value' where DropDown.SelectedValue ='ActualValue'

I have the following code in a VB .NET application. I am trying to update columns in an Oracle table with data with SQL data. When I run the application, I get (ORA-00933: SQL command not properly ended) for the 'or_cmd_3.ExecuteNonQuery()' line.
If I strip out the code and run it in TOAD or SQL Developer, replacing the temp varialve with some bogus data it updates fine. What am I missing?

I am using oracle database and i already created a connection and retrieved data from my oracle DB to Datagridview using oledb commands,now my major challenge which has gotten me sick is to update any changes made in the datagridview to the oracle database. I tried using sqlcommandbuilder but failed. This code is what i used to retrieved the data from oracle and place it into the datagridview.
These are my declarations i made at the beginning of the form:
Private myDA As OleDbDataAdapter
Private myDataSet As DataSet
These are the codes inside the search button to load the retrieved data from oracle into the datagridview
Public con As OleDbConnection = New OleDbConnection("Provider=MSDAORA.1;User ID=SYSTEM; Password=simon; database=project")

I'm new at vb.net programming so be gentle. I have the flowing code

DataGridVew1.DataSource = BSourceItems

I want to add from vb.net a file into a clob column in oracle 9.6.1 (8 mb). When i add the file within a transaction then it goes much longer (10x longer) then when i add it whitout transaction. Why i have to wait so long with transaction object?
Here i have prepared an example code. the first code is without transaction and the second code with transaction. The first code is much faster then the second.
I have the problem only when i want to add the file in a clob column. When i want to add it in a blob column, then i don't have any problem.[code]...
I want to create Table in Oracle database from my asp.net application by using ado.net
View 1 RepliesSo hopefully this is a quick fix but for the life of me I can't figure out how to get my results from a OracleDataReader record set.Just trying to get all the users for a specific TNS into an array. I was able to do this easily before with ADODB, but thought I would try using ODP.net.Here is what I have so far and it definitely gets all the USERs for a given TNS. its when I get to the READ() part where the syntax is ??
View 1 RepliesRelatively new to VB.NET coding. Am creating a pretty simple console application that needs to insert over 50,000 records into an Oracle table (OleDB connection). I tried 3 different methods so far: Individual INSERT, insert using a dataset, & using INSERT ALL (commit every 25 records due to # of columns). It seemed like most articles/posts I read recommended the dataset approach, but the INSERT ALL code was definitely the fastest by far.

I have the following simple Sub to write a dataset back to an Oracle database
[code..]
Checking the logs today I noticed that for some executions I got an ORA-0001 (constraint violation) error. It seems that one of the fields in the oracle table being updated is marked as unique and my dataset contains one or more records that have the same value in that field.
How is this error handled? Does it just not add the violating records? Does it hit the invalid record and quit? Does it rollback?
I need to code the following:
1.Connect to an Oracle database.
2.Execute a query.

I have a VB.Net application that populates an Oracle 11g global temporary table. I can see data in the temporary table by loading it into a grid and everything looks correct.However, when I call an Oracle stored procedure from VB.Net that would manipulate the data in this temporary table, the stored procedure reports that my temporary table is empty.I understood that data in an Oracle global temporary table should be visible to all sessions.

View 3 RepliesI am trying to export an excel file directory into an Oracle table as opposed to looping through the range and executing a lot of insert statements. I would think that there are better ways to accomplish this in .NET but I can't seem to find any other answer besides convert excel to csv & load it using Sql Loader or External Table. Does anyone know a cleaner & more efficient way that looping through the ranges creating & executing insert statements?
