Type		Description
09/23/20249032SnowflakeAdded
  • 外部OAuth がサポートされ、AuthScheme 接続プロパティにOAuthClient 認証オプションが追加され、OAuthAuthenticator 接続プロパティにOther オプションが追加されました。
07/03/20248950SnowflakeAdded
  • 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。
05/17/20248903SnowflakeAdded
  • 新たに"S3Domain" 接続プロパティが追加され、ユーザーがSnowflake ステージのS3ドメインを手動で設定できるようになりました。これは、リージョン固有のドメインを設定する必要がある場合に便利です。

03/18/20238477SnowflakeAdded
  • Added a new Authscheme "ExternalBrowser" to use the OneLogin SSO identity provider. And the connection property "user" is necessary for this AuthScheme.
10/12/20228320TableauAdded
  • Added support for additional localizations in the Windows and Mac packages. Both setups now support all the languages that Tableau supports as of their 2022.2 release.
08/12/20228259TableauChanged
  • Updated connection dialogs to use advanced configuration information provided by drivers. This makes use of the same information as the new dialogs in other editions (like ODBC) to display only the most relevant connection properties.
  • Legacy connectors have been simplified to look more like Tableau JDBC dialogs. Legacy connectors target older Tableau versions which do not support rich connection dialogs like the modern connectors do. Most connectors cannot fit within these limitations.
06/29/20228215SnowflakeChanged
  • Switched to using the LOCAL TEMPORARY table to support the MERGE statement. This saves costs against the Snowflake server.
03/31/20228125SnowflakeAdded
  • Added support for using the GET and PUT commands in the SQL statement. This can be used to upload/download files for Azure/S3/GCP.
12/19/20218023SnowflakeAdded
  • Added support for TVF (table-valued function).
09/02/20217915GeneralAdded
  • Added support for the STRING_SPLIT table-valued function in the CROSS APPLY clause.
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.
07/14/20217865SnowflakeChanged
  • Updated the protocol version to 3.13.5, synced with the latest official JDBC driver.
07/12/20217863SnowflakeAdded
  • Added support for prepared queries via the new connection property, AllowPreparedStatement. Set this property to true to support prepared queries.
04/25/20217785GeneralAdded
  • Added support for handling client side formulas during insert / update. For example: UPDATE Table SET Col1 = CONCAT(Col1, " - ", Col2) WHERE Col2 LIKE 'A%'
04/23/20217783GeneralChanged
  • Updated how display sizes are determined for varchar primary key and foreign key columns so they will match the reported length of the column.
04/16/20217776GeneralAdded
  • Non-conditional updates between two columns is now available to all drivers. For example: UPDATE Table SET Col1=Col2
04/16/20217776GeneralChanged
  • Reduced the length to 255 for varchar primary key and foreign key columns.

Changed
