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.

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.
07/08/20217859GeneralAdded
  • 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.
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
