  • 2 つの列挙値、"Default" および"Text" を持つ新しいプロパティ"BindingType" が追加されました。Default では、Date、Time、Timestamp 型にepoch(nano)エンコーディングを使用します。Text は、Date、Time、Timestamp 型に対して、セッションパラメータに応じた文字列フォーマットを使用します。これにより、Timestamp 型のバッチ処理(upload API)と非バッチ処理(binding API)の間で整合性のある動作が実現します。

07/23/20217874GeneralChanged
  • Updated the Literal Function Names for relative date/datetime functions. Previously, relative date/datetime functions resolved to a different value when used in the projection as opposed to the predicate. For example: SELECT LAST_MONTH() AS lm, Col FROM Table WHERE Col > LAST_MONTH(). Formerly, the two LAST_MONTH() methods would resolve to different datetimes. Now, they will match.
  • As a replacement for the previous behavior, the relative date/datetime functions in the criteria may have an 'L' appended to them. For example: WHERE col > L_LAST_MONTH(). This will continue to resolve to the same values that were previously calculated in the criteria. Note that the "L_" prefix will only work in the predicate - it not available for the projection.

  • Updated the protocol version to 3.13.5, synced with the latest official JDBC driver.

04/23/20217783GeneralChanged
