我是新的VB.net,SQL和甚至phpmyadmin貴。我想刪除保存在我的phpmyadmin記錄,但執行的SqlCommand的的ExecuteNonQuery()時,我得到了一個錯誤如何刪除phpmyadmin中的數據庫記錄?
這是在VB.NET中使用我的代碼:
Public Sub RetrieveInfos(ByRef SQLStatement As String)
Dim cmd As MySqlCommand = New MySqlCommand
With cmd
.CommandText = SQLStatement
.CommandType = CommandType.Text
.Connection = SQLConnection
.ExecuteNonQuery()
End With
'--read the records in database in phpmyadmin gui---
Dim myReader As MySqlDataReader = cmd.ExecuteReader
If myReader.Read Then
lblName.Text = myReader.GetString(0)
lblAge.Text = myReader.GetString(1)
End If
myReader.Close()
SQLConnection.Close()
MsgBox("Records Successfully Retrieved")
SQLConnection.Dispose()
End Sub
Private Sub btnRefresh_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRefresh.Click
Dim SQLStatement As String = "DELETE FROM patient WHERE 1"
RetrieveInfos(SQLStatement)
End Sub
任何幫助,將不勝感激。謝謝!
phpmyadmin是一個用於使用MySQL數據庫而不是數據庫服務器的GUI工具。 – 2012-07-26 17:12:00
'我想...但是我得到了錯誤'錯誤是什麼? – Ghost 2012-07-26 17:12:29
你確定錯誤來自'executivetenonquery'而不是'executereader'嗎? – Ghost 2012-07-26 17:15:56
