  • Removed the Resources table. Users can no longer run a 'SELECT * FROM Resources' query. Instead, they can specify the 'FileSystem' connection property in the connection string by adding a value for 'fileSystemName'. This creates a new table called '(fileSystemName0_resources)' that contains the same metadata as the 'Resources' table did.

  • The ROUND function previously did not accept negative precision values. That feature has now been restored.

  • The UploadFile stored procedure now accepts a folder as a parameter for the Path and FilePath arguments. All the files inside that folder are uploaded to the destination path in parallel. This is not recursive, so the files in the sub folders will not be uploaded.

  • 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.
06/07/20217828ADO.NETAdded
  • Added support for the DbCommand.CommandTimeout property.
06/05/20217826Azure Data Lake StorageAdded

  • Removed support for SSRS 2008.
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.
04/16/20217776ADO.NETChanged
  • 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.
  • Separate EFCore 3.0, 3.1 and EFCore 5 dlls are now shipped with the driver. The 2.0 and 2.1 EFCore dlls are removed.
04/16/20217776GeneralChanged

Changed
  • Updated index naming convention to avoid duplicates.
