  • Tables will now be exposed for empty indices. The exposed tables for empty indices will have the _id and _score columns.
06/23/20238574ElasticsearchAdded
  • Added the ExposeDotIndices connection property. Can be used to control whether dot indices (indices whose name starts with '.') are exposed in table and view listings. Default is 'false', which corresponds to keeping longstanding behavior of not exposing dot indices in table and view listings.
06/20/20238571GeneralAdded

When using the Relational mode of the Datamodel connection property, UseFullyQualifiedNestedTableName controls whether or not the relational tables modeled for nested documents are named with a full representation of their path in the parent, indexed document.
12/14/20228383GeneralChanged
  • Added the Default column to the sys_procedureparameters table.
12/09/20228378ElasticsearchRemoved

  • Added the IsPath column to the sys_procedureparameters table.
06/17/20228203ElasticsearchAdded

  • 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.
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.
