  • Changed the default method for submitting client_credentials grants with OAuth. Before client_credentials would submit OAuthClientId and OAuthClientSecret using the HTTP Authorization header. Now the OAuthPasswordGrantType controls this setting and it defaults to OAuthPasswordGrantType=Post. The previous behavior is still available by setting OAuthPasswordGrantType=Basic.
02/25/20228091jdbcChanged
  • The method DatabaseMetaData.getTypeInfo() now returns all of the data types that the driver supports. Previously, it was returning only a portion of the data types. The types include: tinyint, smallint, int, bigint, float, double, numeric, decimal, bit, date, datetime, time, varchar, binary, uuid.
02/24/20228090jdbcChanged

  • Added support for excluding files based on the ExcludeFiles connection property.
  • Added support for datetime filters in IncludeFiles and ExcludeFiles connection properties. We currently support CreatedDate and ModifiedDate. Ex:
    ExcludeFiles="TXT,CreatedDate<='2020-11-26T07:39:34-05:00'" 
    ExcludeFiles="TXT,ModifiedDate<=DATETIMEFROMPARTS(2020, 11, 26, 7, 40, 50, 000)"
    ExcludeFiles="ModifiedDate>=DATETIMEFROMPARTS(2020, 11, 26, 7, 40, 49, 000),ModifiedDate<=CURRENT_TIMESTAMP()" 
  • Only the following storage sources will have support for filtering by CreatedDate:
    • Box (box://)
    • GCloudStorage (gs://)
    • GoogleDriveStorageSource (gdrive://)
    • OneDrive (onedrive://)
    • SharePoint (sp://)
    • SharePointREST (sprest://)
09/12/20217925jdbcRemoved
  • Removed the IS_READONLY, IS_KEY, NUMERIC_PRECISION, and DECIMAL_DIGITS columns from DatabaseMetadata.GetColumns(), as they are not part of the JDBC Specification. This information is still available via other metadata calls.
09/02/20217915GeneralAdded
  • Added support for the STRING_SPLIT table-valued function in the CROSS APPLY clause.
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.
06/24/20217845ParquetAdded
  • Added support for the GOOGLEJSONBLOB JWT certificate type. This works like the existing GOOGLEJSON certificate type except that the certificate is provided as JSON text instead of as a file path.
06/08/20217829ParquetAdded
  • Added support for the AzureServicePrinciple authentication scheme, which will support both using an OAuthClientSecret, or alternatively using a JWT cert.
06/05/20217826ParquetAdded
  • Added support to authenticate submitting JWT certs instead of the OAuthClientSecret for the AzureAD authentication scheme.
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.
04/23/20217783ParquetDeprecated
  • SSODomain will not be used anymore for OKTA, OneLogin and ADFS. Instead, Domain should be specified.
  • The AzureAccount connection property is deprecated. Instead, AzureStorageAccount should be used.
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

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.
01/14/20217684ParquetAdded
  • Added Insert / Update support.
12/23/20207662ParquetChanged
