Question

我需要在更改DataGridView DataGridView_Manage_Calculations之后更新我的Access数据库，然后点击Button Button_Update。

这是我到目前为止的代码：

Dim dtManage As New DataTable
Dim ManageAdapter As OleDbDataAdapter
Dim Bsource As New BindingSource

Public Sub Show_Panel_Manage_Calculations()
    Panel_Manage_Calculations.Show()

    ManageAdapter = New OleDbDataAdapter("Select Calculation, [Interval], Formula From " & tblName & "", con)
    dtManage.Clear()
    ManageAdapter.Fill(dtManage)
    Bsource.DataSource = dtManage
    DataGridView_Manage_Calculations.DataSource = Bsource

End Sub

Private Sub Button_Update_Click(sender As Object, e As EventArgs) Handles Button_Update.Click
    Dim ObjComander As New OleDbCommandBuilder(ManageAdapter)
    ManageAdapter.Update(dtManage)
End Sub

我收到此错误：Syntax error in INSERT INTO statement.

我做错了什么？

其他信息

Public Sub createTable_Criteria()
    Dim cmd As New OleDb.OleDbCommand("CREATE TABLE " & tblName & "(" & "Calculation Text(10) NOT NULL," & "[Interval] Text NOT NULL," & "Formula Text," & "Tier_Juncture_1 Integer," & "Tier_Juncture_2 Integer," & "Tier_Juncture_3 Integer," & "Weight Integer, CONSTRAINT pk_Calculation PRIMARY KEY (Calculation, [Interval]));", con)
    cmd.ExecuteNonQuery()
End Sub

Answer 1

查看有关错误消息的信息，您的SELECT查询似乎不会在select语句中返回表的主键。在这种情况下，OleDbCommandBuilder不会构建所需的INSERT命令。

您有两种选择：

返回所选表格的主键
为适配器

我不知道你的表的结构（给定dinamically构造的select）但最好的方法是在select语句中返回主键

从DataGridView更改更新Access数据库
