I am using vb.net 2003 and accessing an Access 2002 database via oleDb and Jet 4.0.I am filling a set of text boxes with data from the database. The Connection, DataAdapter and DataSet are all set using the Wizard. The text boxes fill correctly with the first row of data. I then wished to filter the data so I went into the code and added a WHERE clause as follows:WHERE [Boat Name]=" & xid & "xid is the variable name given to the selected boat name. When I run the program I get the following error message:

how to convert this to VB.NET?
What I have right now is this:
Dim users = From users In tempTable _
Distinct Select users.Item("s_userid")

But I pretty sure I shouldn't have to do that. I should be able to get the count in/from that first linq query.
I am trying to AVERAGE 6 different fields on a DataTable, but without grouping. Just the AVERAGE. I have found a couple of examples in C#, but can't find any examples for how to do this in VB.Here is what I have so far:
Dim query = From dtRow In dtIn.AsEnumerable _
Where dtRow.Field(Of String)("FOLLOWUP") = "Alert" _
Select New With { _
.Brand_Functional_Avg = XXX.Average(Function(f) f("Brand_Functional")), _
.Brand_Personal_Avg = XXX.Average(Function(f) f("Brand_Personal")) _
}
What should I use for XXX? I tried all of the options that I could think of and nothing is compiling.
Trust me, if I could write this in C#, I would, but the project requires VB.

Of the 51 Standard Query Operators (of which only 42 are actually query operators), only 24 are directly supported by Visual Basic 9 and just 11 by C# 3: Query Expression Syntax for Standard Query Operators.In many cases, query syntax is arguably more readable than the equivalent method syntax, especially when transparent identifiers are involved. However, that readability breaks down if you have to combine queries and method calls.So the question: What query operators, current or hypothetical, would you like to have your language of choice support in query expression syntax?

View 3 RepliesThis is not a homework of mine and i had never tried ms access database with vb so i just gave it a shot. so this is my first time and i am just trying not asking anyone to complete my homework. I have been searching for this a lot on internet but couldn't find a solution to this so i decided to ask this question here.
i have this sql code. what i want to do is that create a basic login form where users puts it's username in the UsernameTextbox and Password in the PasswordTextbox. If the the information match then a message box appears saying that the user is valid and if the information does not exist, a mesage box appears saying the users is not valid. now everytime i execute(run) the code, i come up with this error: Syntax error (missing operator) in query expression ''UserName' = 'Admin' 'PassWord' = 'testing123''.
The field names(UserName, PassWord) are also correct they are same as in the database. the information put in the username and password textbox are correct and they match the information on the database. But i dont know why this error comes up.

i use a database in access and I use a query for adaptor and dataset.
The query is next:
Select * from table1, table2 where table1.idsomething=table2.id and table2.name= 'Name1' AND datebirth>=#07.25.1988# AND datebirth<=#07.31.1988# order by datebirth asc
The error is: Syntax error in date in query expression
In the database the format date is dd-mm-yy.Why I have this problem? What is wrong at the query?
I am having a problem with this code. I have used this code before on other apps and it works, but I don't have a clue as to what is going on here.
This is the whole event. I get a runtime error msg thats says "Syntax error(Missing Operator) in query expression"
I think this is Legacy SQL coding but I don't know how to make it better.

I know that LINQ queries are deferred and only executed when the query is enumerated, but I'm having trouble figuring out exactly when that happens.Certainly in a For Each loop, the query would be enumerated.What's the rule of thumb to follow? I don't want to accidentally enumerate over my query twice if it's a huge result.
For example, does System.Linq.Enumerable.First enumerate over the whole query? I ask for performance reasons. I want to pass a LINQ result set to an ASP.NET MVC view, and I also want to pass the First element separately. Enumerating over the results twice would be painful.It would be great to turn on some kind of flag that alerts me each time a LINQ query is enumerated. That way I could catch scenarios when I accidentally enumerate twice.
I have 7 company Divisions that sit in an access database.I then use this list to populate two comboboxes in my windows form.However I get a syntax error in my SQL Query if the Division name is more than one word.For example in my access database I have two columns one is a status column and the other is a division column. If for example the Division is called 'Corporate' the status column is called 'Status Corporate' and the division column is called 'Corporate'.The SQL query works fine in this scenario.However if I have a Division that is more than one word, lets say 'Operations Division' I get an error in my SQL Query that says -
