Question

我正在使用.net开发Epicor的自定义。我正在尝试更新一个表，但是，我不知道为什么它不起作用。在关闭应用程序后，字段保持包含相同的值。有什么我想念的吗？提前谢谢！

Dim adapterLaborDtlSearch As LaborDtlSearchAdapter = New LaborDtlSearchAdapter(HHWorkQueueForm)
adapterLaborDtlSearch.BOConnect()
LaborDtlDV = CType(oTrans.EpiDataViews("LaborDtl"), EpiDataView)
Dim laborHedSeq As Integer = LaborDtlDV.dataView(LaborDtlDV.Row)("laborHedSeq")
Dim laborDtlSeq As Integer = LaborDtlDV.dataView(LaborDtlDV.Row)("laborDtlSeq")
Dim laborDtlSchDataSet As Data.DataSet = adapterLaborDtlSearch.GetData(laborHedSeq, laborDtlSeq)
laborDtlSchDataSet.Tables("LaborDtl").Rows(0).BeginEdit
laborDtlSchDataSet.Tables("LaborDtl").Rows(0).Item("LaborQty") = nedShiftQty.value
laborDtlSchDataSet.Tables("LaborDtl").Rows(0).EndEdit
laborDtlSchDataSet.Tables("LaborDtl").AcceptChanges
adapterLaborDtlSearch.Update()

这是更新方法的堆栈跟踪。

在AcceptChanges来电后将通话移至adapterLaborDtlSearch.Update()。

调用AcceptChanges时，任何仍处于编辑模式的DataRow对象都会成功结束其编辑。 DataRowState也会更改：所有已添加和已修改的行变为未更改，并删除已删除的行。

在尝试使用DbDataAdapter.Update方法更新DataSet后，通常会在DataTable上调用AcceptChanges方法。

更新不会更改表上的字段值
