I have problem in my application when updating 3 items otherwise it is as good as work. The problem is when updating the username to the access database an error showing that "Datatype mismatch" when updating the date and time field an error occurs and tells that the "Unknown field type". This is my code where bold faced lines have errors:
Dim objCmd As OleDb.OleDbCommand = New OleDb.OleDbCommand()
objCmd.Connection = con.con
'Make a command to insert data
I'v designed a ms access database table with one field having Datetime datatype. I can Insert data into it from vb.net front end by trns_dt DateTime.Now.DateBut when I fetch records from the tableand assign the dataset datasource as da, it shows datatype mismatch error.
I'm trying something which should be very simple, I have an access database with a column of dates and I want to select a specific date.
Dim StartDate As Date StartDate = txtStartDate.Text Dim DBconnection As OleDb.OleDbConnection Dim strSQL As String = "SELECT * FROM ClientData WHERE Dateofarrival = '" & StartDate & "' "
I keep getting the error "Data type mismatch in criteria expression". The data type in access is set as a short date.
I'm using Visual C# 2008, when i tried to merge my Excel DataTable with my Oracle DataTable for an Update.It prompt out a column that has a Data Type mismatch dispite my column is empty.How can i solve as simple as possible as i have many tables to work with and every table's column might give me a mismatch.
I have a question. When I try to use this piece of code in my program which will add a supplier to the database, I encounter data type mismatch error. As far as I know, the status of the supplier creates the error.How would I store the values of the radio buttons named radActive and radInactive in the database? Should I use Boolean or a String? I am using Microsoft Access as my database and the field of Status is set to Yes/No.
im trying to use this select statement on a OLEDB database and im am getting a data type mismatch.[code]its not just this particular select statement. its any where the where clause is dependant. in the past i have got round this by passing in a parameter but its not my prefered method and id really rather not pass in two dates as parameters.i have looked in to this and found some thing that said that in oledb select commands you need to CONVERT the dates however when i trid that i got an error thar says somthing like CONVERT is not a recognised function.
I am having trouble removing a row from a table of an access database. I'm trying to remove a row based on a date/time that has already passed. Here is the code I have. When I try to run it I get an error.[code]...
data type mismatch criteria error .. please help im getting this error .. and i don't know where's the error ..
Private Sub frmUpdateChapter_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load con.ConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source = D:dbCAI.mdb" con.Open()
Probably a simple problem but I'm failing to see how or why it's happening.
The error message I'm getting is Data type mismatch in criteria expression.
My coding is below:[code...]
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)?
I am getting this error when create new record. Data type mismatch in criteria expression.

i'm connecting to an excel spreadsheet to read some values.basically this module is going to determine if the date is a business day. This is achieved by comparing the date selected against a registered list (that is in the excel spreadsheet) that are holidays etc.
now I seem to be getting the data type mismatch error.. not too sure why at this stage..
So that error doesn't really make since. I mean I know what the error means but my query looks good and is what I expected.Is there any way to see the final outcome from SQLInsert. Parameters.AddWithValue..Before it gets to "SQLInsert.ExecuteNonQuery()" ??

It works fine when I try it on my computer, which I've used to write the app. But it gets the "Data type mismatch in criteria expression" error when I try to save data on the computer where the app is installed and will be used on.I don't get it. Is it because of the operating system?
