Close Method (SQLiteDataReader)
The following example creates a
SQLiteConnection, a
SQLiteCommand, and a
SQLiteDataReader. The example reads through the data, writing it out to the console. Finally, the example closes the
SQLiteDataReader, then the
SQLiteConnection.
public void ReadMyData(string myConnString)
{
string mySelectQuery = "SELECT DeptNo, DName FROM Dept";
SQLiteConnection sqConnection = new SQLiteConnection(myConnString);
SQLiteCommand sqCommand = new SQLiteCommand(mySelectQuery,sqConnection);
sqConnection.Open();
SQLiteDataReader sqReader;
sqReader = sqCommand.ExecuteReader();
// Always call Read before accessing data.
while (sqReader.Read()) {
Console.WriteLine(sqReader.GetInt32(0) + ", " + sqReader.GetString(1));
}
// always call Close when done reading.
sqReader.Close();
// Close the connection when done with it.
sqConnection.Close();
}
Public Sub ReadMyData(myConnString As String)
Dim mySelectQuery As String = "SELECT DeptNo, DName FROM Dept"
Dim sqConnection As New SQLiteConnection(myConnString)
Dim sqCommand As New SQLiteCommand(mySelectQuery, sqConnection)
sqConnection.Open()
Dim sqReader As SQLiteDataReader
sqReader = sqCommand.ExecuteReader()
' Always call Read before accessing data.
While sqReader.Read()
Console.WriteLine(sqReader.GetInt32(0).ToString() + ", " _
+ sqReader.GetString(1))
End While
' always call Close when done reading.
sqReader.Close()
' Close the connection when done with it.
sqConnection.Close()
End Sub
