删除数据库中的记录 (VB.NET)

Question

我正在尝试删除在文本框中输入的人的记录。这是我的代码，我不知道下一步该怎么做，因为我的代码不起作用。

    AcademicAssessmentConnection = New OleDbConnection("provider=microsoft.ace.oledb.12.0;data source=" & Application.StartupPath & "\AdvisorAssessmentTool.accdb")

    AcademicAssessmentConnection.Open()

    AcademicAssessmentCommand = New OleDbCommand()
    AcademicAssessmentCommand.Connection = AcademicAssessmentConnection
    AcademicAssessmentCommand.CommandText = "DELETE (*) from Students where StudentID = @lookup"
    AcademicAssessmentCommand.ExecuteNonQuery()
    MsgBox("Successfully Deleted")
    AcademicAssessmentConnection.Close()

Answer 1

您需要向包含@lookup 值的Command 对象添加一个参数。

AcademicAssessmentCommand.Parameters.AddWithValue("@lookup", lookup);
