在Query String中需要帮助

Question

我必须遍历整个架构并获取具有特定列的所有表。然后从表格和列中我需要搜索特定值，然后更新该值。

以下就是我所拥有的

  Public Function MassDataFieldUpdate(ByVal Column As List(Of String), ByVal whereClause As String) As DataTable
        Dim temp As String = ""
        Dim cSQL As String = String.Format("SELECT TABLE_NAME, COLUMN_NAME FROM information_schema.columns WHERE find_in_set(COLUMN_NAME, 'idUnit') > 0")
        Return _Inst.GetTable(cSQL)
    End Function

这个函数给我一个数据表，它是：

现在我想在datatable上编写另一个查询/ LINQ并遍历到行值为24的所有列并将其更改为88.

因此，如果在表格tblContact中，则列“idUnit＆＃39;有价值24我需要将其更新为＆＃39; 88＆＃39;请指导我。

这就是我现在所拥有的：

LOGIC.VB

 Public Sub MassDataFieldUpdate()
            Dim dt As New DataTable
            Dim Column As List(Of String) = New List(Of String)
            Select Case mode
                Case SMS_Obj.Enumerations.DataUpdateMode.UnitId
                    Column.Add("idUnit")
                Case SMS_Obj.Enumerations.DataUpdateMode.Unknown
                    ' -1
                Case Else
                    ' nothing
            End Select
            dt.Merge(MassDataFieldUpdate(Column))
            'WHAT LINQ QUERY NEEDS TO BE WRITTEN HERE
            ' I need to call 'MassRowUpdate' HERE
        End Sub

DAL.vb

Public Function MassDataFieldUpdate(ByVal Column As List(Of String)) As DataTable
        Dim temp As String = ""
        Dim cSQL As String = String.Format("SELECT TABLE_NAME, COLUMN_NAME FROM information_schema.columns WHERE find_in_set(COLUMN_NAME, '{0}') > 0)", Column)
        Return _Inst.GetTable(cSQL)
    End Function

    Public Sub MassRowUpdate(ByVal table_name As String, ByVal Column As List(Of String), ByVal whereClause As String)
        Dim cSQL As String = String.Format("UPDATE {0} FROM {1} SET {2} {3}", table_name, Column, whereClause)
    End Sub
