.net - UPDATE Command With NULL?
Apr 27, 2011I am trying to update a column in my database with the date selected from a control on my ASP.NET web page. I need to ensure that the code is correct because nothing is updating in the column.
Code:
Command = New SqlCommand("UPDATE Parking SET ParkingStartDate = @StartDate1 WHERE Parking_ID = @radio)", myConn)
Command.Parameters.Add("@StartDate1", SqlDbType.Date).Value = StartDate.SelectedDate
Command.Parameters.Add("@radio", SqlDbType.VarChar).Value = radio
Command.ExecuteNonQuery()
myConn.Close()
if the column is already NULL, is it correct to use the update statement?

Update A Database Row With The Update Command?
Feb 11, 2010is there a way to update a database row with the update command by first defining all parameters and then all values just like you can in the insert command? "insert into table1 (parameter1,parameter2,....) values (value1, value2,....)"something like "set table1 (parameter1, parameter2) values (value1,value 2,...) where ...."?because I only know the syntax to define each parameters value "set table parameter1=value, parameter2=value2... where"

SQL Command String - Update Password Within Database
Nov 17, 2011I have a problem with the code below as a SQL command string. Note: Using .Net Framework 4.0 in Visual Studio 10 Professional. Database is a Microsoft Access file. The idea is that this SQL command string will update a password within my database. Also note that I have tried the string below with and without the ";" at the end and it does not work either way. The problem is most likely extremely obvious, but I can't seem to find it. I have commented below the code what each part of the String is.
"UPDATE Users SET Password='" & tbx1.Text & "' WHERE Username = '" & sUsername & "';"
' Users is my Table name within the Database.
' Password is the field that I want to edit within the Users table.
' tbx1.Text is where the password is stored within a text box.
' Username is the field which I would like to compare with sUsername which is a variable within the code.
Solution was square brackets, Command string now looks like this:
"UPDATE Users SET [Password]='" & tbx1.Text & "' WHERE [Username]= '" & sUsername & "'"

Update Access DB With Passed In Values?
Mar 11, 2010I am currently working on a project that requires an update within an Access Database. There are photo folders, and the user defines the path name via a dialog box. That path name is stored to a string value, and through OleDBReader, the actual name of the photo (from another column in the database) is stored to another string value. Anyway, I have tried a number of methods to update, and nothing is working, here is my code from the OleDBReader on, and the procedure designed to do the update. (note that TargetID represents the primary key of the access DB.. this is why I pass that value in because I can use the Rows.Find(PK) method.. When I use a simpler updating method, I get an error saying I do not have a valid update command). OK Here is the code:
Dim photoSQL As String = "SELECT * FROM PotentialTarget"
Dim oleDbCommand As OleDbCommand = New OleDbCommand(photoSQL, tableConn)
Dim oleDbDataReader As OleDbDataReader = oleDbCommand.ExecuteReader()
