Updated: November 2007

Gets or sets a Transact-SQL statement or stored procedure to insert new records into the data source.

Namespace: System.Data.SqlClient
Assembly: System.Data (in System.Data.dll)

Syntax

Visual Basic (Declaration)

Public Property InsertCommand As SqlCommand

Visual Basic (Usage)

Dim instance As SqlDataAdapter
Dim value As SqlCommand

value = instance.InsertCommand

instance.InsertCommand = value

public SqlCommand InsertCommand { get; set; }

Visual C++

public:
property SqlCommand^ InsertCommand {
    SqlCommand^ get ();
    void set (SqlCommand^ value);
}

/** @property */
public SqlCommand get_InsertCommand()
/** @property */
public  void set_InsertCommand(SqlCommand value)

JScript

public function get InsertCommand () : SqlCommand
public function set InsertCommand (value : SqlCommand)

Property Value

Type: System.Data.SqlClient..::.SqlCommand

A SqlCommand used during Update to insert records into the database that correspond to new rows in the DataSet.

Remarks

During Update, if this property is not set and primary key information is present in the DataSet, the InsertCommand can be generated automatically if you set the SelectCommand property and use the SqlCommandBuilder. Then, any additional commands that you do not set are generated by the SqlCommandBuilder. This generation logic requires key column information to be present in the DataSet. For more information, see Generating Commands with CommandBuilders (ADO.NET).

When InsertCommand is assigned to a previously created SqlCommand, the SqlCommand is not cloned. The InsertCommand maintains a reference to the previously created SqlCommand object.

If execution of this command returns rows, these rows can be added to the DataSet depending on how you set the UpdatedRowSource property of the SqlCommand object.

For every column that you propagate to the data source on Update, a parameter should be added to InsertCommand, UpdateCommand, or DeleteCommand. The SourceColumn property of the parameter should be set to the name of the column. This indicates that the value of the parameter is not set manually, but is taken from the particular column in the currently processed row.

Examples

The following example creates a SqlDataAdapter and sets the SelectCommand, InsertCommand, UpdateCommand, and DeleteCommand properties. It assumes you have already created a SqlConnection object.

Visual Basic

Public Function CreateCustomerAdapter( _
  ByVal connection As SqlConnection) As SqlDataAdapter

    Dim adapter As SqlDataAdapter = New SqlDataAdapter()

    ' Create the SelectCommand.
    Dim command As SqlCommand = New SqlCommand( _
        "SELECT * FROM Customers " & _
        "WHERE Country = @Country AND City = @City", connection)

    ' Add the parameters for the SelectCommand.
    command.Parameters.Add("@Country", SqlDbType.NVarChar, 15)
    command.Parameters.Add("@City", SqlDbType.NVarChar, 15)

    adapter.SelectCommand = command

    ' Create the InsertCommand.
    command = New SqlCommand( _
        "INSERT INTO Customers (CustomerID, CompanyName) " & _
        "VALUES (@CustomerID, @CompanyName)", connection)

    ' Add the parameters for the InsertCommand.
    command.Parameters.Add("@CustomerID", SqlDbType.NChar, 5, "CustomerID")
    command.Parameters.Add("@CompanyName", SqlDbType.NVarChar, 40, "CompanyName")

    adapter.InsertCommand = command

    ' Create the UpdateCommand.
    command = New SqlCommand( _
        "UPDATE Customers SET CustomerID = @CustomerID, CompanyName = @CompanyName " & _
        "WHERE CustomerID = @oldCustomerID", connection)

    ' Add the parameters for the UpdateCommand.
    command.Parameters.Add("@CustomerID", SqlDbType.NChar, 5, "CustomerID")
    command.Parameters.Add("@CompanyName", SqlDbType.NVarChar, 40, "CompanyName")
    Dim parameter As SqlParameter = command.Parameters.Add( _
        "@oldCustomerID", SqlDbType.NChar, 5, "CustomerID")
    parameter.SourceVersion = DataRowVersion.Original

    adapter.UpdateCommand = command

    ' Create the DeleteCommand.
    command = New SqlCommand( _
        "DELETE FROM Customers WHERE CustomerID = @CustomerID", connection)

    ' Add the parameters for the DeleteCommand.
    command.Parameters.Add( _
        "@CustomerID", SqlDbType.NChar, 5, "CustomerID")
    parameter.SourceVersion = DataRowVersion.Original

    adapter.DeleteCommand = command

    Return adapter
End Function

public static SqlDataAdapter CreateCustomerAdapter(
    SqlConnection connection)
{
    SqlDataAdapter adapter = new SqlDataAdapter();

    // Create the SelectCommand.
    SqlCommand command = new SqlCommand("SELECT * FROM Customers " +
        "WHERE Country = @Country AND City = @City", connection);

    // Add the parameters for the SelectCommand.
    command.Parameters.Add("@Country", SqlDbType.NVarChar, 15);
    command.Parameters.Add("@City", SqlDbType.NVarChar, 15);

    adapter.SelectCommand = command;

    // Create the InsertCommand.
    command = new SqlCommand(
        "INSERT INTO Customers (CustomerID, CompanyName) " +
        "VALUES (@CustomerID, @CompanyName)", connection);

    // Add the parameters for the InsertCommand.
    command.Parameters.Add("@CustomerID", SqlDbType.NChar, 5, "CustomerID");
    command.Parameters.Add("@CompanyName", SqlDbType.NVarChar, 40, "CompanyName");

    adapter.InsertCommand = command;

    // Create the UpdateCommand.
    command = new SqlCommand(
        "UPDATE Customers SET CustomerID = @CustomerID, CompanyName = @CompanyName " +
        "WHERE CustomerID = @oldCustomerID", connection);

    // Add the parameters for the UpdateCommand.
    command.Parameters.Add("@CustomerID", SqlDbType.NChar, 5, "CustomerID");
    command.Parameters.Add("@CompanyName", SqlDbType.NVarChar, 40, "CompanyName");
    SqlParameter parameter = command.Parameters.Add(
        "@oldCustomerID", SqlDbType.NChar, 5, "CustomerID");
    parameter.SourceVersion = DataRowVersion.Original;

    adapter.UpdateCommand = command;

    // Create the DeleteCommand.
    command = new SqlCommand(
        "DELETE FROM Customers WHERE CustomerID = @CustomerID", connection);

    // Add the parameters for the DeleteCommand.
    parameter = command.Parameters.Add(
        "@CustomerID", SqlDbType.NChar, 5, "CustomerID");
    parameter.SourceVersion = DataRowVersion.Original;

    adapter.DeleteCommand = command;

    return adapter;
}
