    ExcludeFiles="TXT,CreatedDate<='2020-11-26T07:39:34-05:00'" 
    ExcludeFiles="TXT,ModifiedDate<=DATETIMEFROMPARTS(2020, 11, 26, 7, 40, 50, 000)"

  • 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.
06/24/20217845CSVAdded
  • 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.
06/10/20217831CSVAdded
  • Added support for TypeDetectionScheme=ColumnCount. This enables the user to specify via the ColumnCount connection property exactly how many columns to report (all as varchar), bypassing any normal procedure of attempting to introspect the data to dynamically determine columns.
06/08/20217829CSVAdded
  • Added support for the AzureServicePrinciple authentication scheme, which will support both using an OAuthClientSecret, or alternatively using a JWT cert.
06/05/20217826CSVAdded

04/23/20217783GeneralChanged

04/23/20217783CSVDeprecated
  • 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.
