[RESOLVED] ExecuteNonQuery not executing

Hi

I'm trying to execute a SQL command, but I just can't find out why this is not working. This is how I defined the "execute" function in my class named "clsSQL":

Code:

---

    ''#...
    Private m_sConnectionString As String = String.Empty
    ''#...
    Friend WithEvents m_objConnection As SqlConnection
    Friend WithEvents m_objCommand As SqlCommand
    ''#...

        Public Function OpenConnection() As Boolean
            Try
                m_objConnection = New SqlConnection(m_sConnectionString)
                m_objConnection.Open()
                Select Case m_objConnection.State
                    Case Data.ConnectionState.Open : Return True
                    Case Else : Return False
                End Select
            Catch ex As Exception
                RaiseEvent OnError("OpenConnection", ex)
            End Try
        End Function


        Public Function Execute(ByVal sQuery As String) As Boolean
                Try
        #If DEBUG_MODE Then
                    Debug.WriteLine(sQuery)
        #End If
                    m_objCommand = New SqlCommand(sQuery, m_objConnection)
                    m_objCommand.ExecuteNonQuery()
                    m_objCommand = Nothing
                    Return True
                Catch ex As Exception
                    RaiseEvent OnError("Execute", ex)
                End Try
            End Function
''#..
''#...

This is how I'm calling it:

Code:

---

        Using oSQL As New clsSQL(My.Settings.projectConnectionString)
            If oSQL.OpenConnection Then
                strSQL = "INSERT INTO ficheiros (nome_ficheiro, caminho_ficheiro, checksum) values ('nomefich', 'nomepath', '000')"
                oSQL.Execute(strSQL)
            Else
              MsgBox("fail")
            End If
        End Using

---

The code raises no error, it is just not saving the data in the database. The error is not in the SQL command, I've manually tested it ;)

For instance, I can execute perfectly the next function without any kind of problems:

Code:

---

    Public Function ToDataGrid(ByVal oDataGrid As DataGridView, _
                              ByVal sQuery As String, _
                      Optional ByVal sTable As String = "") As Boolean
        Try
#If DEBUG_MODE Then
            Debug.WriteLine(sQuery)
#End If
            Dim objDataSet As New DataSet
            objDataSet = ToDataSet(sQuery, sTable)
            oDataGrid.DataSource = objDataSet.Tables(0)
            objDataSet.Dispose()
            objDataSet = Nothing
            Return True
        Catch ex As Exception
            RaiseEvent OnError("ToDataGrid", ex)
        End Try
    End Function

---

And this is how I'm calling it:

Code:

---

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    Using oSQL As New clsSQL(My.Settings.projectConnectionString)
        If oSQL.OpenConnection Then
            oSQL.ToDataGrid(Me.DataGridView, "select * from table")
        End If
    End Using
End Sub

---

Probably, I just need another pair of eyes, 'cause I can't see what am I doing wrong :|
Could this be related to the database and not to my code?

Thanks

I would suggest to create a function which will return object and gets the sql to be executed and the type of data to be return back. And you could cast it back after calling the function

And how do you know this?

Hi

I'm very sorry, but I didn't understand what you mean with your suggestion.
(I'm not English native-speaker)
:confused:
can you be more explicit in your suggestion, if possible?

I've "debugged/stepped into" all my code lines and no error was raised.

This is the part I want to know more about:
"it is just not saving the data in the database"

HOW do you know it is NOT saving the data?

ohh, I'm sorry.:p
I've opened the table and I saw that the table is empty (0 rows) and I performed a "select count(..." and it is returning "0", on the Database explorer.

thanks

ok... In my signature there is a link titled "I swear I saved my data, where'd it run off to?" ... click it... read the thread, and see if it applies to you in this case. If it does, the answer is provided in there. If it does not apply to this case, then let us know.

Also - it might help to post the connection string you are using.

I will read it.

many thanks

You were right. I was saving my data, just was looking in the wrong place. :p

It's a common problem. 9 times out of 10, if there are no errors... you're simply checking the data in the wrong place. It's gotten most of us at some point.
