속성 값

OdbcCommand

채우기 작업을 수행하는 동안 OdbcCommand에 배치하기 위해 데이터 소스에서 레코드를 선택하는 데 사용되는 DataSet입니다.

예제

다음 예제에서는 를 만들고 OdbcDataAdapter 및 InsertCommand 속성을 설정합니다SelectCommand. 개체를 이미 만들었다고 OdbcConnection 가정합니다.

public static OdbcDataAdapter CreateDataAdapter(
    OdbcConnection connection)
{
    string selectCommand =
        "SELECT CustomerID, CompanyName FROM Customers";

    OdbcDataAdapter adapter = new OdbcDataAdapter(
        selectCommand, connection);
    adapter.MissingSchemaAction = MissingSchemaAction.AddWithKey;

    // Create the Insert, Update and Delete commands.
    adapter.InsertCommand = new OdbcCommand(
        "INSERT INTO Customers (CustomerID, CompanyName) " +
        "VALUES (?, ?)");

    adapter.UpdateCommand = new OdbcCommand(
        "UPDATE Customers SET CustomerID = ?, CompanyName = ? " +
        "WHERE CustomerID = ?");

    adapter.DeleteCommand = new OdbcCommand(
        "DELETE FROM Customers WHERE CustomerID = ?");

    // Create the parameters.
    adapter.InsertCommand.Parameters.Add("@CustomerID",
        OdbcType.Char, 5, "CustomerID");
    adapter.InsertCommand.Parameters.Add("@CompanyName",
        OdbcType.VarChar, 40, "CompanyName");

    adapter.UpdateCommand.Parameters.Add("@CustomerID",
        OdbcType.Char, 5, "CustomerID");
    adapter.UpdateCommand.Parameters.Add("@CompanyName",
        OdbcType.VarChar, 40, "CompanyName");
    adapter.UpdateCommand.Parameters.Add("@oldCustomerID",
        OdbcType.Char, 5, "CustomerID").SourceVersion =
        DataRowVersion.Original;

    adapter.DeleteCommand.Parameters.Add("@CustomerID",
        OdbcType.Char, 5, "CustomerID").SourceVersion =
        DataRowVersion.Original;

    return adapter;
}

Public Function CreateDataAdapter( _

    Dim adapter As OdbcDataAdapter = _

    adapter.MissingSchemaAction = MissingSchemaAction.AddWithKey

    ' Create the Insert, Update and Delete commands.

        "@CustomerID", OdbcType.Char, 5, "CustomerID")
    adapter.InsertCommand.Parameters.Add( _
        "@CompanyName", OdbcType.VarChar, 40, "CompanyName")

    adapter.UpdateCommand.Parameters.Add( _
        "@CustomerID", OdbcType.Char, 5, "CustomerID")
    adapter.UpdateCommand.Parameters.Add( _
        "@CompanyName", OdbcType.VarChar, 40, "CompanyName")
    adapter.UpdateCommand.Parameters.Add( _
        "@oldCustomerID", OdbcType.Char, 5, "CustomerID").SourceVersion = _
        DataRowVersion.Original

    adapter.DeleteCommand.Parameters.Add( _
        "@CustomerID", OdbcType.Char, 5, "CustomerID").SourceVersion = _
        DataRowVersion.Original

    Return adapter

설명

SelectCommand 가 이전에 만든 OdbcCommand에 할당되면 가 OdbcCommand 복제되지 않습니다. 대신 은 SelectCommand 이전에 만든 OdbcCommand 개체에 대한 참조를 유지 관리합니다.

행을 반환하지 않으면 SelectCommand 에 테이블이 추가 DataSet되지 않으며 예외가 발생하지 않습니다.
