In This Topic
    InsertCommand Property (SQLiteDataAdapter)
    In This Topic
    Gets or sets a SQLite statement to insert new records into the data source.
    Syntax
    'Declaration
     
    Public Shadows Property InsertCommand As SQLiteCommand
    public new SQLiteCommand InsertCommand {get; set;}

    Property Value

    A SQLiteCommand used during an update operation to insert records in the data source that correspond to new rows in the System.Data.DataSet.
    Remarks
    During an update operation, if InsertCommand is not set and primary key information is present in the System.Data.DataSet, you can use the SQLiteCommandBuilder class to automatically generate InsertCommand, and additional commands needed to reconcile the System.Data.DataSet to the data source. To do this, set the SelectCommand property of the SQLiteDataAdapter. For more information see "Automatically Generated Commands" in the Microsoft .NET Framework SDK documentation.

    Note: If execution of this command returns rows, these rows may be added to the System.Data.DataSet depending upon how you set the Devart.Common.DbCommandBase.UpdatedRowSource property of the SQLiteCommand object.

    Example
    The following example demonstrates how to retrieve and manipulate data using SQLiteDataAdapter.
    public void UseDataAdapter(SQLiteConnection sqConnection)
    {
      SQLiteDataAdapter myAdapter = new SQLiteDataAdapter("SELECT DeptNo, DName FROM Dept", sqConnection);
      myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey;
      DataSet myDataSet = new DataSet();
      myAdapter.Fill(myDataSet,"Departments");
      object[] rowVals = new object[2];
      rowVals[0] = 40;
      rowVals[1] = "Operations";
      myDataSet.Tables["Departments"].Rows.Add(rowVals);
      myAdapter.InsertCommand = new SQLiteCommand("INSERT INTO Dept (DeptNo, DName) " +
        "VALUES (:DeptNo, :DName)", sqConnection);
            myAdapter.InsertCommand.Parameters.Add("DeptNo", SQLiteType.Int32, 0, "DeptNo");
      myAdapter.InsertCommand.Parameters.Add("DName", SQLiteType.Text, 15, "DName");
      myAdapter.Update(myDataSet,"Departments"); 
      //Get all data from all tables within the dataset
      foreach(DataTable myTable in myDataSet.Tables)
      {
        foreach(DataRow myRow in myTable.Rows)
        {
          foreach (DataColumn myColumn in myTable.Columns)
          {
            Console.Write(myRow[myColumn]+"\t");
          }
          Console.WriteLine();
        }
        Console.WriteLine();
      }
    }
    Public Sub UseDataAdapter(ByVal sqConnection As SQLiteConnection)
      Dim myAdapter As SQLiteDataAdapter = New SQLiteDataAdapter("SELECT DeptNo, DName FROM Dept", sqConnection)
      myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey
      Dim myDataSet As DataSet = New DataSet
      myAdapter.Fill(myDataSet, "Departments")
      Dim rowVals(1) As Object
      rowVals(0) = "40"
      rowVals(1) = "Operations"
      myDataSet.Tables("Departments").Rows.Add(rowVals)
      myAdapter.InsertCommand = New SQLiteCommand("INSERT INTO Dept (DeptNo, DName) " & _
          "VALUES (:DeptNo, :DName)", sqConnection)
      myAdapter.InsertCommand.Parameters.Add("DeptNo", SQLiteType.Int32, 0, "DeptNo")
      myAdapter.InsertCommand.Parameters.Add("DName", SQLiteType.Text, 15, "DName")
      myAdapter.Update(myDataSet, "Departments")
      Dim myTable As DataTable
      Dim myRow As DataRow
      Dim myColumn As DataColumn
      ' Get all data from all tables within the dataset
      For Each myTable In myDataSet.Tables
        For Each myRow In myTable.Rows
          For Each myColumn In myTable.Columns
            Console.Write(myRow(myColumn) & Chr(9))
          Next myColumn
          Console.WriteLine()
        Next myRow
        Console.WriteLine()
      Next myTable
    End Sub
