  • Added support for Apache HDFS (webhdfs://) as a storage source.
03/09/20228103JSONChanged
  • 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.

    <api:call op="utiladoSleep?timeout=x" />
    where x is the delay in seconds.
10/07/20217950JSONAdded
  • 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://)
09/02/20217915GeneralAdded
  • 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.
06/24/20217845JSONAdded
  • 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.
06/08/20217829JSONAdded
  • Added support for the AzureServicePrinciple authentication scheme, which will support both using an OAuthClientSecret, or alternatively using a JWT cert.
06/05/20217826JSONAdded
  • Added support to authenticate submitting JWT certs instead of the OAuthClientSecret for the AzureAD authentication scheme.
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.
04/23/20217783JSONDeprecated
  • 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.
04/16/20217776GeneralAdded
  • 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.
04/15/20217775GeneralChanged
  • Kerberos authentication is updated to use TCP by default, but will fall back to UDP if a TCP connection cannot be established.
03/26/20217755JSONChanged
  • Updated the way default table names are computed so that the file name is taken into account. The driver will now try to use the file name for the table name instead of using the term "JSONData" every time.
  • The provider will now consistently use the following values when naming the table that uses the root JSONPath. In order:
    • The value of the roottablename input attribute, if given.
    • The value of the TableName connection property, if given.
    • The filename of either the MetadataDiscoveryURI, or the first URI if that is not provided. The filename does not include the extension. If there is no URI, or the filename is empty (e.g. "/home/user/.json"), or the URI is for HTTP/HTTPS then the URI is ignored.
    • The value "JSONData".
  • This naming process applies even in JSONRows mode, where before the name of the table was always "JSONData" with no way for the user to override it.
  • Vertically flattened tables now use the table name instead of always using the prefix "json".
  • None of the above changes apply when the connection is made in backwards compatibility mode.
12/21/20207660JSONAdded
  • Added support for reporting special types for aggregates. If the user opts in via SupportNativeDataType and are using JDBC, then the driver will report JSONArray as the type name for array aggregates and JSONObject for object aggregates (if FlattenObjects is disabled)
