I am using Visual Basic to control a Windows Access database. I have succeeded in adding a record to the database, it works fine. But now I am struggling to update the database!I get the "Data type mismatch in criteria expression" error on the 'ERROR' line. On the line before, "7" is just another column name in the database.Here is my code for a certain button

I'm trying to update ms access data using vb.net and here's my code:
updateuserclass.vb
Public Class UpdateUser
Dim bankai As New Updater
[Code]...
What might be wrong in here?I set it all to string, is the primary key usernum not a string.
This is the code
Imports System.Data, System.Data.OleDb
Public Class Form1
Public CON As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source =" & Application.StartupPath & "\bible.mdb")
[Code] .....
I got that Error for
data2.Fill(ds1, "Bible")
Data type mismatch in criteria expression
the combobox1 value is numbers
I tried this code
Dim sql1 As String = "select distinct ChapterNum from Bible where BookNum ='" & Trim(ComboBox1.Text) & "'"
And this code
Dim sql1 As String = "select distinct ChapterNum from Bible where BookNum ='" & Val(ComboBox1.Text) & "'"
And it still got the same error.
I have looked at this for hours and can't seem to figure out what is causing the datatype mismatch. I am trying to insert from asp.net to a access database

I have an error "ERROR [22018] [Microsoft][ODBC Microsoft Access Driver] Data type mismatch in criteria expression". I am using VBdotNet2005 and MS Access as its database, and I can't really get the hang of this error.
View 8 RepliesI am using parameters in my code to update records in an access database.
One of the fields I am using in my sql Query Update statement is the ID field and it is causing this error -
Data type mismatch in criteria expression.
I have isolated the error and it occurs with the ID field in the Update query.
The DataType for the ID Field in Access is AutoNumber, Field Size is Long Integer and New Values is Increment.
In my code I have declared the Data Type as Integer.
Is there an obvious mistake in my code?

Probably a simple problem but I'm failing to see how or why it's happening.

The error is coming up when i'm filling the dataset, i've already figured that it works when the WHERE is removed.
So i'm assuming the mismatch must be from (VirtualLearningExercises.Level = '" & UserLevel). UserLevel is defined as a integer in vb and VirtualLearningExercises.Level is data type number on access.
I've had this problem many, many times. And it's always turned out to be a small typo or "" around an integer, but I just cannot find what's wrong with my SQL Statement this time! SELECT Card_ID FROM Payment WHERE Customer_ID = 12 AND Card_Number = 1231231231231231 The table and fields are named correctly (the table is actually a query).The only thing I can think of is the card number being too large, however it works fine in my INSERT INTO statement!All of the fields are formatted as their respective data types, ie. Integers are set to integer, not string.

I run a query on Access and although it warns me about null fields, it can still run the query and add the rows.However, when I run through JET in VB.NET, it says "Data type mismatch in criteria expression".Is there a way for JET to behave like Access (ie. still run the query and add the rows)?
