Description
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。

02/25/20228091JDBCChanged
  • The method DatabaseMetaData.getTypeInfo() now returns all of the data types that the driver supports. Previously, it was returning only a portion of the data types. The types include: tinyint, smallint, int, bigint, float, double, numeric, decimal, bit, date, datetime, time, varchar, binary, uuid.
02/24/20228090JDBCChanged

10/27/20217970JDBCChanged
  • Added support for JDK 17
09/12/20217925JDBCRemoved
  • Removed the IS_READONLY, IS_KEY, NUMERIC_PRECISION, and DECIMAL_DIGITS columns from DatabaseMetadata.GetColumns(), as they are not part of the JDBC Specification. This information is still available via other metadata calls.
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
  • Updated index naming convention to avoid duplicates.

03/19/20217748SnowflakeAdded
  • Added support for Google Cloud Platform for Snowflake.

Deprecated
  • Deprecated SSOIdp and SSOIdpDomain. SSOIdp is taken from the AuthScheme now. SSOIdpDomain is replaced with the Domain, which may be passed in via the SSOProperties.
