    OracleDataAdapter Class
    In This Topic
    Represents a set of data commands and a data source connection that are used to fill the System.Data.DataSet and update an Oracle data.
    The OracleDataAdapter serves as a bridge between a System.Data.DataSet and a data source for retrieving and saving data. The OracleDataAdapter provides this bridge by using System.Data.Common.DbDataAdapter.Fill to load data from the data source into the System.Data.DataSet, and using System.Data.DataSet.Update() to send changes made in the System.Data.DataSet back to the data source.

    OracleDataAdapter is used in conjunction with OracleConnection and OracleCommand to increase performance when connecting to Oracle.

    The OracleDataAdapter also includes the SelectCommand, InsertCommand, DeleteCommand, UpdateCommand, and TableMappings properties to facilitate loading and updating of data.

    Note: This class is not available in .NET Standard 1.3 compatible assembly. It is available only in the assembly for full .NET Framework and .NET Standard 2.0 compatible assembly.

    The following example demonstrates how to retrieve and manipulate data using OracleDataAdapter.
    public void UseDataAdapter(OracleConnection myConnection)
      OracleDataAdapter myAdapter = new OracleDataAdapter("SELECT DeptNo, DName FROM Test.Dept", myConnection);
      myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey;
      DataSet myDataSet = new DataSet();
      object[] rowVals = new object[2];
      rowVals[0] = 40;
      rowVals[1] = "Operations";
      myAdapter.InsertCommand = new OracleCommand("INSERT INTO Test.Dept (DeptNo, DName) " +
        "VALUES (:DeptNo, :DName)", myConnection);
      myAdapter.InsertCommand.Parameters.Add("DeptNo", OracleDbType.Integer, 0, "DeptNo");
      myAdapter.InsertCommand.Parameters.Add("DName", OracleDbType.VarChar, 15, "DName");
      //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)
    Public Sub UseDataAdapter(ByVal myConnection As OracleConnection)
      Dim myAdapter As OracleDataAdapter = New OracleDataAdapter("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"
      myAdapter.InsertCommand = New OracleCommand("INSERT INTO Test.Dept (DeptNo, DName) " & _
          "VALUES (:DeptNo, :DName)", myConnection)
      myAdapter.InsertCommand.Parameters.Add("DeptNo", OracleDbType.Integer, 0, "DeptNo")
      myAdapter.InsertCommand.Parameters.Add("DName", OracleDbType.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
        Next myRow
      Next myTable
    End Sub
