10/12/20228320TableauAdded

  • Enable OP_MSG protocol against MongoDB server higher or equal than 5.1.0.
08/18/20228265MongoDBAdded
  • Updated driver to support communication over OP_MSG protocol.
08/12/20228259TableauChanged
  • Updated connection dialogs to use advanced configuration information provided by drivers. This makes use of the same information as the new dialogs in other editions (like ODBC) to display only the most relevant connection properties.
  • Legacy connectors have been simplified to look more like Tableau JDBC dialogs. Legacy connectors target older Tableau versions which do not support rich connection dialogs like the modern connectors do. Most connectors cannot fit within these limitations.
03/15/20228109MongoDBAdded
  • Added support for SQL such as "INSERT INTO foo_table(foo_c) VALUES(())" to insert empty BSON array values for the "foo_c" column.
  • Added support for when the connection property WriteSchema is set to RawValue, new columns may be specified and created in the course of the update statement.
02/07/20228073MongoDBChanged
  • 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.
12/22/20218026MongoDBAdded
  • Added the WriteConcern connection property.
12/15/20218019MongoDBChanged
  • We will now validate if a table exists during the CREATE TABLE statement.
12/14/20218018MongoDBAdded
  • Added support for nested array inserts in a vertically flattened array.
11/11/20217985MongoDBAdded
  • Added support for Mongo X-509 authentication.
09/23/20217936MongoDBAdded
  • Added support for TLS encrypted communication over SSH tunnel.
09/16/20217929MongoDBAdded
  • Added the attribute "other:tabletype" when rsd schema files are generated from the CreateSchema stored procedure. This attribute indicates if the table schema should map to a collection or view on the MongoDB server.
09/02/20217915GeneralAdded
  • 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.
05/18/20217808MongoDBAdded
  • 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.
04/16/20217776TableauChanged
  • Improved the connection dialog configuration experience.
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
  • The AuthMechanism connection property id deprecated. Use the AuthScheme connection property instead.
11/18/20207627MongoDBAdded
  • Added support for SSH.
08/28/20207545MongoDBChanged
  • Returned all available databases on listing schema.
06/05/20207461MongoDBAdded
