InsertCommand Property (SqlDataAdapter)

In This Topic

Gets or sets a SQL Server statement to insert new records into the data source.

Syntax

Visual Basic
C#

'Declaration
 
Public Shadows Property InsertCommand As SqlCommand

public new SqlCommand InsertCommand {get; set;}

Property Value

A SqlCommand 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 SqlCommandBuilder 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 SqlDataAdapter. 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 SqlCommand object.

Example

The following example demonstrates how to retrieve and manipulate data using SqlDataAdapter.

csharp

public void UseDataAdapter(SqlConnection myConnection)
{
  SqlDataAdapter myAdapter = new SqlDataAdapter("SELECT DeptNo, DName FROM Test.Dept", myConnection);
  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 SqlCommand("INSERT INTO Test.Dept (DeptNo, DName) " +
    "VALUES (:DeptNo, :DName)", myConnection);
        myAdapter.InsertCommand.Parameters.Add("DeptNo", SqlType.Int, 0, "DeptNo");
  myAdapter.InsertCommand.Parameters.Add("DName", SqlType.VarChar, 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();
  }
}

Visual Basic

Public Sub UseDataAdapter(ByVal myConnection As SqlConnection)
  Dim myAdapter As SqlDataAdapter = New SqlDataAdapter("SELECT DeptNo, DName FROM Test.Dept", myConnection)
  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 SqlCommand("INSERT INTO Test.Dept (DeptNo, DName) " & _
      "VALUES (:DeptNo, :DName)", myConnection)
  myAdapter.InsertCommand.Parameters.Add("DeptNo", SqlType.Int, 0, "DeptNo")
  myAdapter.InsertCommand.Parameters.Add("DName", SqlType.VarChar, 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
