Remarks

The SQLiteDataAdapter serves as a bridge between a System.Data.DataSet and a data source for retrieving and saving data. The SQLiteDataAdapter 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.

SQLiteDataAdapter is used in conjunction with SQLiteConnection and SQLiteCommand to increase performance when connecting to SQLite.

The SQLiteDataAdapter also includes the SQLiteDataAdapter.SelectCommand, SQLiteDataAdapter.InsertCommand, SQLiteDataAdapter.DeleteCommand, SQLiteDataAdapter.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.

Example

The following example demonstrates how to retrieve and manipulate data using SQLiteDataAdapter.
C#csharpCopy Code
public void UseDataAdapter(SQLiteConnection sqConnection)
{
  SQLiteDataAdapter myAdapter = new SQLiteDataAdapter("SELECT DeptNo, DName FROM Dept", sqConnection);
  myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey;
  DataSet myDataSet = new DataSet();
  myAdapter.Fill(myDataSet,"Departments");
  object[] rowVals = new object[2];
  rowVals[0] = 40;
  rowVals[1] = "Operations";
  myDataSet.Tables["Departments"].Rows.Add(rowVals);
  myAdapter.InsertCommand = new SQLiteCommand("INSERT INTO Dept (DeptNo, DName) " +
    "VALUES (:DeptNo, :DName)", sqConnection);
  myAdapter.InsertCommand.Parameters.Add("DeptNo", SQLiteType.Int32, 0, "DeptNo");
  myAdapter.InsertCommand.Parameters.Add("DName", SQLiteType.Text, 15, "DName");
  myAdapter.Update(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();
  }
}
