更新查詢正在跳過if語句vb.net

Question

我現在不是爲什麼該方法在if語句中被跳過任何人都可以幫我解決這個問題嗎？

這裏的更新SQL查詢

Public Sub Edituser() 
    conn() 
    dbconn.Open() 
    sql = "UPDATE player SET First Name=@1 Last Name=@2, Gender=@3, Date of Birth=@4, Civil Status=@5, Nationality=@6, Address=@7, Status=@8 WHERE ID = " + TextBox8.Text + "" 
    Try 
     dbcomm = New MySqlCommand(sql, dbconn) 
     dbcomm.Parameters.Add(New MySqlParameter("@1", TextBox1.Text)) 
     dbcomm.Parameters.Add(New MySqlParameter("@2", TextBox2.Text)) 
     dbcomm.Parameters.Add(New MySqlParameter("@3", TextBox9.Text)) 
     dbcomm.Parameters.Add(New MySqlParameter("@4", TextBox3.Text)) 
     dbcomm.Parameters.Add(New MySqlParameter("@5", TextBox4.Text)) 
     dbcomm.Parameters.Add(New MySqlParameter("@6", TextBox5.Text)) 
     dbcomm.Parameters.Add(New MySqlParameter("@7", TextBox6.Text)) 
     dbcomm.Parameters.Add(New MySqlParameter("@8", TextBox7.Text)) 
     dbread = dbcomm.ExecuteReader() 
     dbread.Close() 
     MsgBox("Successfully updated!") 
    Catch ex As Exception 
    Finally 
     dbconn.Close() 
    End Try 
End Sub 

和這裏的if語句

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click 
    If TextBox1.Text = "" Or TextBox2.Text = "" Or TextBox3.Text = "" Or TextBox4.Text = "" Or TextBox5.Text = "" Or TextBox6.Text = "" Or TextBox7.Text = "" Or TextBox9.Text = "" Then 
     MsgBox("Please complete all the fields") 
    Else 
     Dim result As Integer = MessageBox.Show("Are you sure you want to Edit the information?", "Update", MessageBoxButtons.OKCancel, MessageBoxIcon.Question) 
     If result = DialogResult.OK Then 


      Edituser() 

      MsgBox(" Player information Updated!") 
      Me.Close() 
      Player.Show() 
     End If 

    End If 
End Sub 

在此先感謝。

Answer 1

你UPDATE語句語法錯誤的，因爲它缺少,和列名正確引用如下面指出

sql = "UPDATE player SET `First Name`=@1, `Last Name`=@2, Gender=@3, `Date of Birth`=@4, 

Answer 2

sub被稱爲edituser，你在調用editplayer？

好的。你正在將空的catch塊中的錯誤壓扁。最有可能的是你正在碰到一個sql錯誤傳遞日期參數作爲一個字符串。

您需要刪除try catch以查看錯誤消息，或將其輸出到console/msgbox。

@Rahul說的也是正確的。可能是兩者的結合。
