I query on the data bank with Ado, put everything in a Dataset, changes the data and then lets it write in the table. How can it be that is written in all lines except the first one? I do not find any error. Someone can help me? Here the code:

I'm wondering if its possible to change the query that grabs the data from the dataset at runtime, in order to produce a report based on different criteria.My project doesnt use dataset, and I've had to make one purely for the reports I'm currently using the mySQL .net connector calling everything via code, as well as the query I want to make at the time.Also, I don't want the report to be embedded in the application but be a seperate file as the report may change frequently (the layout of it)I've tried setting the build action as none, but I just get an error in the intermediate window.
View 1 RepliesI have tried everything I can to get beyond this error which shows below as <<<<< error here. It is trying to fill a dataset from a data adapter. If I change the SELECT statement to just SELECT * FROM xTable I get the correct number of records in each table. But anytime I try with a more complex statement I get the error message shown below which indicates System.Data.Common.DbDataAdapter.Fill(DataSet dataSet. I've completely erased all data and entered a new set of test data so I know there is no problem with relationships. Each table has primary key which is foreign key in other table. IS there something wrong with the Imports section: Imports System

How do you query a Dataset with SQL queries? I'm using VB with Visual Studio 2005. I've got a large library of SQL queries I'd like to run in-memory on a Dataset.All the examples in the documentation show how to "query a dataset with code," but none show how to run a simple SQL query against a dataset. I've seen other threads that say you can do so, but no code examples. Can anyone provide sample code to show how you would run a simple SQL "Select..." query (using the same syntax you would use to query a database) on an in-memory dataset?

View 6 RepliesThe SQL string won't return data from Access. I've tested this exact SQL String in Access and it works fine.First of all, Am I getting a SQL query from Access in the proper manner?Second... should I be using a stored procedure for this?

View 8 RepliesI've written a bunch of queries that bring back a set of results that look like the following. I have a user level column in an employees table which I'm trying to pull the value from. Only one result (number) will ever be returned. For instance the query will be like: Select username, userlevel from employees where username = "joe" So i'd be bringing back just the level, say 7.

I have a dataset called Me.VelocipedeDBDataSet and there is a table within the dataset called Contact.How can i check the contact table and output the results of rows which have a value for an attribute called AccntRep that matches a global variable known as repNo
I had though that the solution may be something like
If Me.VelocipedeDBDataSet.Contact.Rows.Contains(repNo) Then
Panel3.Visible = True
MsgBox("Account Rep Found", MsgBoxStyle.OkOnly, "Account Rep")
End If
but it has not worked,
I added queries to my dataset via the designer. Is there a way to use variables in those queries?
View 1 Replieshow to pass a parameter to a predefined parameter in a dataset. I've found everywhere a solution if you build the sqldata adapter and the dataset in the code. Then you can pass the parameter like: da.SelectCommand.Parameters.Add("@param1", SqlDbType.Char).Value = param1_variable (as example)
But if you have builded a dataset (with table adapters), and then in the form app you want just to pass the param1 to a DataGridView1 (as example) which is using the table adapter, I did not find how to do this.
I don't have the same problem when using an untyped dataset.
OK. I have a typed dataset MyDS with a typed datatable MyTable (TableID, Title, Message).
The table gets filled with results from two tables, using a UNION ALL
Select
TableAID,
TableATitle,

Is this how typed datasets handles UNION? I didn't want to create two typed datatables and create separate SQL for each and create a relation.
I have a dataset column that I am keeping comments in. If the row has no comment in it(defualt string value is "", not NULL), I don't want it to show up on my report. How can I fill only the datarows that have text in them and not the ones that are empty. I've tried to filter the columns results by Not Nothing, but everything shows up. I'm guessing because it's actually not NULL since the string is "". How can I filter these results correctly?

This is how I update a table using DataAdapter and DataSet in VB using SQL Server[code]...
I know that the Fill method does not make sense in case of an INSERT statement, but I am new to this technology and the above statement does the job and updates the table w/o problems. My question is this: If there was an error (say a duplicate key error) how would I know this in my application? Should I be putting the above code in a try/catch block?
Also, if there is a "proper" method for running INSERT statements using a DataAdapter/DataSet combination that does not use the Fill method, please indicate that as well.
I create a dataset and configure the query builder and in the filter i key in this "?" and when I search the name by enter the full name it will show but what I want is just type "A" and it will show the whole name starting with A. I stuck in this problem what the code to do in order to type just 1 letter and show the whole name starting with first letter that I want.

I am trying to call a SELECT query (with parameters) in Access from VB.Net 2008. I am able to call queries without parameters using the code below.

However, they are all for ms access action (update, delete, etc) queries using ExecuteNonQuery which does not return a dataset.
