  • Added support to automatically resolve the fully qualified name of the schemas and views based on the specified schema and view name in the query.
  • Added the CrossAccountId connection property used to retrieve metadata from a different AWS Glue account.
  • Added support for the STRING_SPLIT table-valued function in the CROSS APPLY clause.
  • Added the KeySeq column to the sys_foreignkeys table.
  • Added the new sys_primarykeys system table.
  • 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.

  • Added support for federated queries. The provider now supports queries ( joins, unions etc ) on cross catalogs and schemas.
06/25/20217846Amazon AthenaAdded

  • Updated how display sizes are determined for varchar primary key and foreign key columns so they will match the reported length of the column.
  • Separated the ADO.NET Provider assembly and Entity Framework Core 5 Nuget packages.
  • Single precision floating point numbers are now reported as with the Data Type Name as "real". Double precision floating point numbers now have their Data Type Name reported as "float". This change does not impact the actual data types of these columns - only the reported data type name.
