Access :: Data Type Mismatch While Inserting Into A Number Field In An Access Database Using A Parameterized Query?
Jun 9, 2010
I have a data type mismatch while inserting into a number field in an access database using a parameterized query.I think this should be pretty simple but I am still learning a lot.
[Code]....
I have some commented out as I am working one field at a time. The working fields are textboxes and the non working ones are dropdown lists. But I think it may be the field that the list is drawing from? Not sure.
I am getting this' Data type mismatch error' when i click on a submit button after tag selection. It was working before but now it is not working. It say there is an error on line 105.[Code]....
I have used the repeater function in an aspx page to create a discussion/fourm style page where user can posts comments, but when I try and write a comment I get this error; Data type mismatch in criteria expression. The user gets to the discussion page from a link in a gridview so that it displays all the posts on the specific film, and the correct posts come up, its just when a user wants to post something themsevles I get the error.This is the code in the discussion.aspx.vb page
I have one question here.I created a registration form using asp.net and c#.

in that table I have an id field which is a text field in access database consists of guid starting with letter P
when I inserting the data from aspx form...the guid is not inserting into the table.
one of my datarecord in that table with the id field is like this.(.P11111111-1BBB-4444-A9D1-111111111111)
need to insert anoother record in that table that field must be generate with the ID starting with P..its an guid.. the creating guid in the aspx.cs page..??
I am using C# windows based GUI and MS-Access as my database. Unfortunately, I cannot insert a record with a numeric value, this means that one of my field is a number data type. Below is my code;
so I have a web programming assignment for university where I'm building a website that uses an Access database but I have hit a brick wall with something.I'm using parameterized queries to query my database. For one of my queries, I want to be able to take a bunch of parameters that are optional, and if they aren't needed I'll pass in a value of null and I'd like the part of the where clause relevant to them to evaluate to true. This is straightforward in most databases, from my understanding you could do something like to make param1 an optional parameter.
WHERE ((@param1 = ARandomColumnName) OR (@param1 = null))
However this can't be done using Access, as all parameters in a query are represented by a ?. Every ? is assumed to refer to a different parameter, so if you want to use a parameter more than one (like the above code I wrote does) then you'd have to pass it twice. This seems hacky to meSo what do I do? I have spent *hours* googling and banging my head on the desk. I'll cry if I missed something really obvious
I have problem while I'm inserting some values to access database ,my query contains From as fieldname this is the query: Insert into Bank (TrancheDBID,TxnType,CACN,MatchCACN,PlanAssignDate,AssignDate,ActiveDate,From,To) values (809,'Assigned','','0156-02-01','15/05/2001 12:00:00 AM','30/11/2009 12:00:00 AM','7/10/2001 12:00:00 AM','HIL','KAH')
I have tried to put [From] but it doesnt work in vb.net, however it does directly on access
This is a query to an old FoxPro database on a server (Same Network). This work in the execution, but just passing the date values as aaaa/mm/dd.On my page when a pass two DateTime Parameters from two TextBox it throw "Unable to recognize the string as a valid DateTime Value"I'm using Ajax Calendar exterder on the textbox to be more specific.Here, (My Country) the format i'm using es dd/mm/aaaaAnd when i select the datepicker it comes in this format, and then a get the DateTime error type.I can get the rows in the query builder just passing the date like "2010/01/15" and "2010/01/30" for example.Hay can i force the texbox to get this format aaaa/mm/dd?
During an adaption of a book based example application, to use an access database instead of sql server - I have come up with the final issue: It will not insert into the database! I suspect it might be to do with the OrderID, I do have it set to autonumber,but I am not too sure. This is the class that does the inserts, by adding customer information to customer table, order information to order table and ordeitems information to the orderitems table. When submitting this information on the webpage, there is the custom error that an error has occurred in your order due to this code page code behind
I want to Check Gr #(PK) of student wheter exist in table or not id exist show Msg in Label after lost focus from text box .. I tried AutoNumber in Access but it showing error while insertion Note : im using form View control for insertion...
I have a SQL database. I am getting a datatable from SQL. In SQL Query the table is having null values in the output. But when it is coming to the front end, the null values are replaced by empty values.
So in the front end in the datatable i am having empty values in some cells. I am trying to insert this datatable into access. For this i am using following code...
OleAdpData.InsertCommand.Connection = OleConn; // OleConn is the OleDbConnection OleAdpData.InsertCommand.Connection.Open(); OleAdpData.Update(dtData); // dtData is the datatable OleAdpData.InsertCommand.Connection.Close();
It is inserting the datatable to access database. But it is inserting the empty spaces as present in the datatable. I want to insert NULL into the cells in access datatable where the cells are empty. Where should i add my logic for this.
em all new in C# and .NET.I am following this tutorial: [URL]And i am at step 3: Adding Parameterized Methods to the Data Access Layer - i have No problems in getting out all information from my database.But when i try to get a specific item by CategoryID i get a Error.This is what i type in my Query in the table adapter:
SELECT ProductID, ProductName, SupplierID, CategoryID, QuantityPerUnit, UnitPrice, UnitsInStock, UnitsOnOrder, ReorderLevel, Discontinued FROM Products WHERE CategoryID = @CategoryID
Here is the error i get when i click finish:The wizard detected the following problems when configuring TableAdapter Query "FillByCategoryID":
Details: Generated SELECT statement. Error in WHERE clause near '@'. Unable to parse query text.
Is there anything missing in IIS 6.0 that prevents me from (Insert into table) using MS-Access?
Explain: The application works fine under Visual Studio 2008 IDE the insert into table works fine with no error, Also I tested with hosting provider and works fine with no problem. but now I have published the same exact app in a dedicated server windows 2003 with IIS 6.0 .NET framework 2.0 with latest service pack I gave IIS_WPG write/modify access to the folder where MS-Access database is located and database but at the time of insert an error pop-up. I need to install in the Server or settings in the IIS to recognize my MS-Access db is it some office runtime that I am missing. (BTW I am using OLEDB connection string in my C# )
Using System.Data.OleDb;
I can retrieve data off of it with no problem but when I try to insert is when it fails I thought the problem was Access Rights but I do not think is the case.
I have a form wilh couple of Drop downs and text boxes and a Data Grid View which displays data from Access Table. When I hit add button on the form, I can see the data being added to the Grid View. But when I close the form and open the Access Database File (.mdb), the respective table is empty. The Access Table is not being updated. Second time if I open the form, the Grid View is also empty.I am pasting my code here.

I am starting a new project in ASP.NET (With silverlight) - I would like to get expert opinion about how to design the data access.I can use DataAccess Layer with SQL helper, but the challenge is every new field that I add needs to be added in the sql helper.I am trying to see if there is a way to design the system, so that it appears in the front end when a new field is added. I don't want to have in the ASPX files (binding in controls) I want to have ability to change items in code. Essentially I am trying to see the best option to have a database application.

Can a query output made in MS ACCESS be accessed as a database in Visual Studio 2008?
I have a Parent and Child Table in MS Access with a one-to-many relationship. I created a query in Access that would produce a result table and I want the contents of this Query to be displayed in a Data Grid in Visual Studio 2008.
i am new to asp.net programming i am trying to connect asp.net web application with ms access 2007 database. i have taken with two text boxes and when i enter some data in it and press submit button the data must load in access db i created with same fields.
my code is :
[code]....
Syntax error in string in query expression what is the correct way of inserting data into access db and what is the Syntax error in string in query expression.
when i first made the DB i used access 2010 which uses the 2007 file type which supports attachments, however asp.net doesnt support the 2007 format. and the 2003 file type doesnt support attachments, i assume i use the OLE object data type but i have no idea how i get my aspx page "new.aspx" to upload an attachment. plus i want to restrict the file type to *.jpg
So I have created a log-in screen that allows you to create a user at the same time. I wanted to make sure that if there was already a UserID registered that if a user tried to register with the same ID that an error message would show rather than my whole website crashing.
This is my code:
[Code]....
The code to place the data into the database works fine by itself but when I put it into this if statement the data no longer goes into the database.
If this the correct way to do this for making sure that a user cannot create a profile with a user id that is already present or is there a simpler way? I have tried to do it with a customvalidator but that did not work at all.
i have a problem executing an insert query. whenever i try to insert i have an exeption telling me it cant execute because a record needed in another table; where i select a value form that other table according a listbox, and then insert it into this table. here is a sample of my code:
OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=|DataDirectory|emp2.mdb");
int a = 0; conn.Open(); string sqlcmd = "select id from nationality where descreption = '" + DropDownList1.Text + "'"; OleDbCommand readNatCmd = new OleDbCommand(sqlcmd, conn); OleDbDataReader readerNat = readNatCmd.ExecuteReader(); while (readerNat.Read()) { a = readerNat.GetInt32(0); } readerNat.Close(); conn.Close(); string saveEmpcmd = @"insert into employee " + "(nationality) " + "values (@nationality)"; OleDbCommand objCmd = new OleDbCommand(saveEmpcmd, conn); objCmd.Parameters.AddWithValue("@nationality", a); conn.Open(); objCmd.ExecuteNonQuery(); conn.Close();
now, the form executes with no errors, but it catches an exeption caused by the ExecuteNonQuery funtion; here it is in details:
System.Data.OleDb.OleDbException: You cannot add or change a record because a related record is required in table 'nationality'. at System.Data.OleDb.OleDbCommand.ExecuteCommandTextErrorHandling(OleDbHResult hr) at System.Data.OleDb.OleDbCommand.ExecuteCommandTextForSingleResult(tagDBPARAMS dbParams, Object& executeResult) at System.Data.OleDb.OleDbCommand.ExecuteCommandText(Object& executeResult) at System.Data.OleDb.OleDbCommand.ExecuteCommand(CommandBehavior behavior, Object& executeResult) at System.Data.OleDb.OleDbCommand.ExecuteReaderInternal(CommandBehavior behavior, String method) at System.Data.OleDb.OleDbCommand.ExecuteNonQuery() at Default2.Button1_Click(Object sender, EventArgs e) in c:Documents and SettingsAdministratorMy DocumentsVisual Studio 2005WebSitesempDefault2.aspx.cs:line 305
when i remove the relation between the tables, the exeption isnt catched anymore, but the value stored in the employee table is 0 how can i solve this?
