  • The ROUND function previously did not accept negative precision values. That feature has now been restored.
04/25/20248881Apache CouchDBChanged

03/26/20248851Apache CouchDBChanged
  • Fixed the incorrect scanning of dynamic columns and their data types when FlexibleSchema is enabled and when TypeDetectionScheme is set to "RowScan" (both are default configurations).
03/15/20248840GeneralAdded
  • Created a new SQL function called STRING_COMPARE that provides java's String.compare() ability to SQL queries. Returns a number representative of the compared value of two strings

10/27/20238700JDBCChanged
  • Added support for Connection.abort() method.
08/04/20238616Apache CouchDBAdded

04/28/20228153JDBCChanged
  • Removed support for JRE 1.6. JRE 1.8 and above is now required.
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
  • Corrected the return value of method DatabaseMetaData.supportsOuterJoins(), which used to return an incorrect value.
12/22/20218026Apache CouchDBAdded
  • Added support for listing Views and retrieving data from them. This is controlled by the ListViews property which by default is set to false. Set this property to true for Apache CouchDB views to show up when listing tables.
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.
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 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.
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.
04/16/20217776GeneralChanged
  • Updated implicit and metadata caching to improve performance and support for multiple connections. Old metadata caches are not compatible - you need to generate new metadata caches if you are currently using CacheMetadata.
