  • Updated connection dialogs to use advanced configuration information provided by drivers. This makes use of the same information as the new dialogs in other editions (like ODBC) to display only the most relevant connection properties.
  • Legacy connectors have been simplified to look more like Tableau JDBC dialogs. Legacy connectors target older Tableau versions which do not support rich connection dialogs like the modern connectors do. Most connectors cannot fit within these limitations.
05/13/20228168ServiceNowAdded
  • The new OAuthPassowrd authentication method has been added, which will replace the GrantType Password functionality. OAuthPassword requires OAuthClientId, OAuthClientSecret, Username, and Password.

Deprecated
  • OAuthGrantType has been deprecated. Use AuthScheme instead.

Changed
  • Column sizes reported by the ServiceNow Metadata API for the columns of type STRING are not taken into consideration anymore because the endpoint is unreliable.
12/11/20218015ServiceNowAdded
  • Added support to expose the ServiceNow database views as views when the the IncludeDatabaseViews connection property is set to true.
11/10/20217984ServiceNowAdded
  • Added support for Single Sign On (SSO) connection with PingFederate as the Identity Provider (IdP).
10/13/20217956ServiceNowAdded
  • Added the GetColumnsMetadata connection property, which controls when and how the driver should get the columns metadata. When setting it to 'OnUse', the driver will execute the table specific metadata calls the first time the table is referenced, provided the metadata for the table in question aren't already cached.
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.
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.
04/16/20217776TableauChanged
  • Improved the connection dialog configuration experience.
04/15/20217775ServiceNowDeprecated
  • Deprecated Instance connection property.

Replacement
  • The URL connection property replaces the Instance connection property. The user should now set the base URL of the ServiceNow instance site, instead of the instance Id. For example: https://MyInstance12345.service-now.com.
04/13/20217773ServiceNowChanged
  • The OneLogin method we used previously has been deprecated by OneLogin. We have updated our design to use the latest version of the OneLogin API, which now requires a seperate OAuthClientId and OAuthClientSecret associated with your OneLogin app to be passed in through SSOProperties. The APIKey that was formerly passed in through SSOProperties for OneLogin is removed.
  • OneLogin also no longer uses SSOLoginURL. Instead, Subdomain and AppId should be specified inside the SSOProperties.
03/24/20217753ServiceNowDeprecated
  • Deprecated SSOUser, SSOPassword, SSOProvider, OktaAppEmbedLink and OKTAApiToken connection properties.

Replacements
  • User and Password replaces SSOUser and SSOPassword.
  • Authscheme replaces SSOProvider.
  • SSOLoginURL replaces OktaAppEmbedLink as it is more generic and applicable to other SSO providers.
  • ApiToken replaces OKTAApiToken as it is more generic and applicable to other SSO providers.
