02/24/20228090jdbcChanged

  • Support for JDK 17
09/12/20217925jdbcRemoved
  • Removed IS_READONLY, IS_KEY, NUMERIC_PRECISION, DECIMAL_DIGITS 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.
08/07/20217889GeneralChanged
  • Added the KeySeq column to the sys_foreignkeys table.
08/06/20217888GeneralChanged
  • Added the new sys_primarykeys system table.
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 vs te predicate. Ie: 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. Ie: WHERE col > L_LAST_MONTH(). This will continue to resolve to the same values that previously were calculated in the criteria. Note that the "L_" prefix will only work in the predicate - it not available for the projection.
07/08/20217859GeneralAdded
  • Added the TCP Logging Module for the logging information happening on the TCP wire protocol. The transport bytes that are incoming and ongoing will be logged at verbosity=5.
05/28/20217818Amazon RedshiftAdded
  • Added support for returning native Redshift datatypes in metadata. 'SupportNativeDataType=True' can be added via the Other connection property to enable this functionality.
04/23/20217785GeneralAdded
  • 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

Changed
  • Reduced the length to 255 for varchar primary key and foreign key columns.
  • Updated implicit and metadata caching to improve performance and support for multiple connections. Old metadata caches are not compatible - you would need to generate new metadata caches if you are currently using CacheMetadata.
  • Updated index naming convention to avoid duplicates
  • Updated and standardized Getting Started connection help.
  • Added the Advanced Features section to the help of all drivers.
  • Categorized connection property listings in the help for all editions.
