Hi,
When I set the dateformat to unixepoch the maximum date I can get back from a
query is 2038-01-19. This appears to be a problem in the wrapper as SQLite
itself is using 64bit integers for dates.
You can reproduce the problem like this:
[Test]
public void ShouldDoSparseTimeSeriesTransform2()
{
ExecuteNonQuery("CREATE TABLE Test_RAW (Date DATETIME, Id INT, Value INT,
PRIMARY KEY (Date, Id))");
ExecuteNonQuery("INSERT INTO Test_RAW VALUES(strftime('%s', '2038-01-20'),
1, 1)");
var result = ExecuteQuery("SELECT * FROM Test_RAW");
// Set breakpoint here and inspect the result.
Assert.AreEqual(1, result.Rows.Count);
}
private void ExecuteNonQuery(string command)
{
using (var cmd = new SQLiteCommand(command, m_connection))
{
cmd.ExecuteNonQuery();
}
}
private DataTable ExecuteQuery(string query)
{
using (var cmd = new SQLiteCommand(query, m_connection))
{
using (var da = new SQLiteDataAdapter(cmd))
{
var dataTable = new DataTable();
da.Fill(dataTable);
return dataTable;
}
}
}
private SQLiteConnection m_connection;
internal static SQLiteConnection GetNewInMemoryConnection()
{
var builder = new SQLiteConnectionStringBuilder
{
DataSource = ":memory:",
DateTimeFormat = SQLiteDateFormats.UnixEpoch
};
return new SQLiteConnection(builder.ConnectionString);
}
[SetUp]
public void SetUp()
{
m_connection = GetNewInMemoryConnection();
m_connection.Open();
}
[TearDown]
public void TearDown()
{
m_connection.Close();
m_connection.Dispose();
}
