  • Made our DateTime to String conversion uniform across our drivers. Previously we returned exactly the string value returned from MongoDB when requesting a DateTime column as a String. Instead, we will now convert the value to a DateTime object before returning a string to ensure pairity with our other tools.
  • In order to control the response format when retrieving a DateTime column as a String, set the DateTimeStringFormat connection property. For example: DateTimeStringFormat=yyyy-MM-ddTHH:mm:ss.fffZ.

  • Added support for the STRING_SPLIT table-valued function in the CROSS APPLY clause.
08/25/20217907MongoDBAdded
  • Added support for better path collision detection for MongoDB server version 4.4 and higher. The change is related to this issue: https://docs.mongodb.com/manual/release-notes/4.4-compatibility/#path-collision-restrictions
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.
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.

  • Added support for nested array vertical flattening on DataModel=Relational.
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.
04/15/20217775GeneralChanged
  • Kerberos authentication is updated to use TCP by default, but will fall back to UDP if a TCP connection cannot be established.
04/06/20217766MongoDBDeprecated
