Error As No Value Given For One Or More Required Parameters.[code]...
View 2 RepliesI wanted to know how I can solve my error.I used the "Add New Datasources" wizard to create a conection to my acces database with visual basic.net 2010. I then added two more after I created the datasources and I dragged the table navigator from the dataset from the datasouces window and I ran the system and It was bringing the information and was working great. However I then decided to add a few more columns to my table, and that is where the problem began the next time I tried to run the system it gives the error "no value given for one or more parameters"If you think it you can achieve it

This was working fine yesterday, today all I did was change the database and its location as well as update all the dataset objects, and now its not working. The only thing I am thinking is that I didn't copy the database to the program directory, but I tried to copy it into there manually and I am still getting an error.

Dim username As String = TextBox1.Text

what is the error.

I am trying to returns records based on the last name of a customer in an access db. When I run the query in Access it works fine, the name in the examples returns 3 records with that last name.

The bold/underlined text is where the error is coming up.What am i doing wrong? I've got a feeling it is something really stupid as i modelled the code on an example project that a teacher gave me, so it's practically the same code except for the field names etc.

I have a connection to a MS SQL database, which I understand is capable of handling multiple SQL statements in one Execution, ie
Code:
Using cmdExe As New System.Data.SqlClient.SqlCommand
sSQL = "Delete * from mytable where UniqueID=123;Insert into mytable (UniqueID, Field) values (123, 'something')"
cmdExe.CommandText = strSingleSQLLine
cmdExe.ExecuteNonQuery()
End Using
will delete from "mytable" and insert a new record all at once. This is great, but I want to expand upon that to use parameters because using string concatenation in my SQL queries is a bad idea. Now my question is this. If I add a parameter which is used in multiple SQL statements, do I have to add the parameter VALUE twice to the command object? ie, will the following code work?
Code:
Using cmdExe As New System.Data.SqlClient.SqlCommand
sSQL = "Delete * from mytable where UniqueID=@uniqueID;Insert into mytable (UniqueID, Field) values (@uniqueID, 'something')"
cmdExe.Parameters.AddWithValue("@uniqueID", 123)
[code]....
There are two questions here actually...can I add the parameters before setting the command text, and do I have to add the same parameter over and over again?
I am pretty sure this is a basic syntax error, I am new at this and basically figuring things out by trial and error... I am trying to insert data from textboxes into an Access database, where the primary key fields in tableCourse are prefix and course_number.
