Devart.Data.SQLite Namespace > SQLiteDataAdapter Class : SelectCommand Property

Gets or sets a SQLite statement used to select records in the data source.


Visual Basic (Declaration) 
Public Shadows Property SelectCommand As SQLiteCommand
public new SQLiteCommand SelectCommand {get; set;}

Property Value

A SQLiteCommand that is used during a fill operation to select records from the data source for placement in the System.Data.DataSet.


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

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

This property supports the InterForm technology.


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

public void CreateDataAdapter(SQLiteConnection sqConnection)
  SQLiteDataAdapter myAdapter = new SQLiteDataAdapter();
  myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey;
  DataSet myDataSet = new DataSet();
  myAdapter.SelectCommand = new SQLiteCommand("SELECT DeptNo, DName FROM Dept", sqConnection);
  //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)
C#Visual BasicCopy Code
Public Sub CreateDataAdapter(ByVal sqConnection As SQLiteConnection)
  Dim myAdapter As SQLiteDataAdapter = New SQLiteDataAdapter
  myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey
  Dim myDataSet As DataSet = New DataSet
  myAdapter.SelectCommand = New SQLiteCommand("SELECT DeptNo, DName FROM Dept", sqConnection)
  myAdapter.Fill(myDataSet, "Dept")
  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
