SelectCommand Property

Gets or sets an Oracle statement used to select records in the data source.

[Visual Basic]
Public Property SelectCommand As OracleCommand

[C#]
public OracleCommand SelectCommand {get; set;}

Return Type

A OracleCommand that is used during a fill operation to select records from the database for placement in the DataSet.

Remarks

When SelectCommand is assigned to a previously created OracleCommand, the OracleCommand is not cloned. Instead, the SelectCommand maintains a reference to the previously created OracleCommand object.

If SelectCommand does not return any rows, no tables are added to the DataSet, and no exception is raised.

This property supports the InterForm technology.

Example

The following example creates a OracleDataAdapter, sets some of its properties, retrieves data from a table, and displays it.

[C#]

public void CreateDataAdapter(OracleConnection myConnection) 
{ 
  OracleDataAdapter myAdapter = new OracleDataAdapter(); 
  myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey; 
  DataSet myDataSet = new DataSet(); 
  myAdapter.SelectCommand = new OracleCommand("SELECT DeptNo, DName FROM Test.Dept", myConnection); 
  myAdapter.Fill(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 CreateDataAdapter(ByVal myConnection As OracleConnection)
   Dim myAdapter As OracleDataAdapter = New OracleDataAdapter
   myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey
   Dim myDataSet As DataSet = New DataSet
   myAdapter.SelectCommand = New OracleCommand("SELECT DeptNo, DName FROM Test.Dept", myConnection)
   myAdapter.Fill(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
