May i know what is going wrong to my Update statement.
I am creating a form that is able to update data in SQL server after selecting an MS Access file (.mdb). I am having an issue where the data has a single quote ('). I found out that the solution was to use Replace() - to replace the single quote with two single quotes - Replace(string, "'", "''").Now, for some reason, I am getting an error "Conversion from type DBNull to type String is not valid." Here is the code.
cmd = New SqlCommand("Update Child Set " & _
"TopLevelProject = '" & row("TopLevelProject") & "' ," & _

Syntax error (missing operator) in query expression '''system time'''.this is the error that appears
this is my code:
Dim sqlCmd As String
Dim x As Date
x = Format(Now(), "General Date")
[code].....
the fields in the tables are all text fields.is there any way to fix this error? perhaps it is in my query but i really cant find a solution.is there an alternative to get what i want my program to do?it is basically entering an ID number and finding the record with the same idnumber and putting the system time on the timein field for that record.

I get a "Syntax error in INSERT INTO statement" on the da.update line. The bulk of the code is copied from a working section of the program, I have just added the "newrow" stuff. I am pretty confident I have the names of all the fields correct.
I have a form with comboboxes, if the user doesnt select a value in the box I want a null to be sent to the database. The insert works fine, i look at the record in the db and see the null. The update doesnt work. gives me a n "Update statement conflicted with foreign key constaint....."
Public Sub Update()
TableAdapterCreate().Update(ID1, ID2, CType(cbox1.SelectedValue, Integer), CType(cbox2.SelectedValue, Integer), CType(cbox3.SelectedValue, Integer), CType(cbox4.SelectedValue, Integer),
[CODE]...
As I step through the selected value of the cbox 5 is shown as nothing (which it should be because the user didnt select a value for this combobox). I assume this needs to be a null instead of nothing to get written to the database. the combox boxes need to match a primary key in another table so sending a 0 would also result in the forieign key error since the related table does not have a 0 ID field.
I have a datagrid with data and I want to update a database with the data on the datagrid.

Dim RowCount As Integer = DataGridView1.Rows.Count - 1
Dim ColumnCount As Integer = DataGridView1.Columns.Count - 1
Dim RowIndex, ColumnIndex As Integer

View 1 RepliesI currently have a problem attepting to update a record within my database. I have a webpage that displays in text boxes a users details, these details are taken from the session upon login. The aim is to update the details when the user overwrites the current text in the text boxes.I have a function that runs when the user clicks the 'Save Details' button and it appears to work, as i have tested for number of rows affected and it outputs 1. However,when checking the database, the record has not been updated and I am unsure as to why.I've have checked the SQL statement that is being processed by displaying it as a label and it looks as so:
UPDATE [users]
SET [email] = @email,
[firstname] = @firstname,
[code].....
I'm trying to update a specific record based off of a users selection. Regarding Entity Framework syntax, I'm not very familiar. Is it possible to achieve this SQL statement in Entity FrameWork?
View 3 RepliesI'm trying to refresh the datagrid after using the SQL UPDATE statement. The data changes physically in the database but the datagrid is not affected. The data is changed only after i restart the program.
How can i get the datagrid to refresh or update? I have tried using, among other code, the refresh() method, but it does not work.
