  • Support for parsing datetime formats using ".S" and ",S" for milliseconds and nanoseconds.
09/12/20259386GeneralAdded
  • Added the IsInsertable, IsUpdateable, and IsDeleteable columns to the sys_tables table.
09/10/20259384GeneralChanged
  • All columns in statically defined Views are now reported as read-only.
09/03/20259377GeneralChanged
  • Corrected the behavior when IN criteria with NULL values are used in the projection part. It now returns NULL instead of 0. For example, "NULL IN (1,2)" returns "NULL".
09/01/20259375GeneralAdded
  • Added support for using the CAST function with infinity values. This function can cast "inf" and "-inf" to DOUBLE, FLOAT, or REAL.
08/21/20259364GeneralChanged
  • Report behavior change:
    • Fixed inconsistent string value comparisons in non-table queries.
    • For example, "SELECT 'A' = 'a'" previously returned false, but it now returns true.
08/13/20259356GeneralChanged
  • Changed the maximum number of pages held in memory from 15 to 5 for the page providers to decrease heap usage.
07/18/20259330RESTRemoved
  • Removed the OAuthGrantType property. The grant type is now set implicitly through the 'AuthScheme' property. For example, you can use the 'OAuthPassword' AuthScheme instead of AuthScheme=OAuth with OAuthGrantType=Password.
06/25/20259307GeneralRemoved
  • Removed the "ADLS Gen 1" value from the ConnectionType property.
06/20/20259302GeneralAdded
  • Created the following functions:
    • TEXT_ENCODE: encodes a string into a different charset (UTF8 → UTF7 and returns a binary array as the result).
    • TEXT_DECODE: takes a binary array and decodes it back into a string when provided the charset.
    • BASE64_ENCODE: takes a binary array and encodes it as a base64 string (varchar).
    • BASE64_DECODE: takes a base 64-encoded string and decodes it into a binary array.
06/18/20259300GeneralChanged
  • The internal code for exception handling has been refactored. Exception messages returned during certain error conditions may now have different wording or formatting.
06/17/20259299RESTRemoved
  • Removed the DataSource connection property. Use the URI connection property instead.
06/09/20259291RESTRemoved
  • Removed the ProjectId property for the Google Cloud Storage ConnectionType.
05/27/20259278GeneralRemoved
  • Removed the "Proprietary" enum option from ProxyAuthscheme.
05/15/20259266RESTAdded
  • Added support for reading .7z (7-Zip) archive files.
04/07/20259228RESTAdded
  • Added support for the IAMSecretKey AuthScheme for cloud storage connections that use access and secret key credentials. This naming better reflects the underlying authentication method and aligns with terminology used by cloud storage providers.

Deprecated
  • Deprecated the HMAC AuthScheme. While it remains supported for backward compatibility, it is no longer recommended due to naming ambiguity.
02/15/20259177GeneralAdded
  • Added support for converting unsigned integer types to the nearest signed data type that has enough precision to hold the unsigned value.This is done for JDBC only because it does not have support for unsigned data types.
11/27/20249097GeneralAdded
  • Added ThreadId to LogModule output. Logfile lines now include the Thread ID associated with the action being performed.
08/23/20249001RESTAdded
  • Added OAuthPKCE as an authentication option when ConnectionType is set to Google Cloud Storage and Google Drive.
  • Added OAuthClient as an authentication option when ConnectionType is set to Box.

  • Added support for the following AWS regions: HYDERABAD, MELBOURNE, CALGARY, SPAIN, ISOLATEDUSEAST, ISOLATEDUSEASTB, and ISOLATEDUSWEST.
07/04/20248951RESTRemoved
  • The ConnectionType property is now computed based on the specified URI.
06/18/20248935GeneralAdded
  • Added support for the "TELAVIV" region (Israel) in the AWSRegion connection property.
05/09/20248895GeneralChanged

  • The ROUND function doesn't accept the negative precision values anymore.

Changed
  • The returning types of the FDMonth, FDQuarter, FDWeek, LDMonth, LDQuarter, LDWeek functions are changed from Timestamp to Date.
  • The return type of the ABS function will be consistent with the parameter value type.
11/28/20238732GeneralAdded
  • Added the HMACSHA256 formatter to allow for secrets to be decoded if it is in base64 format
09/02/20238645RESTAdded
  • Added the [sys_tables].[XPath] column, which will include a JSON-style or XML-style xpath for a table for Format=JSON or Format=XML respectively.
08/26/20238638RESTRemoved
  • Removed the default "TXT,TAB" value for IncludeFiles property. IncludeFiles now has no default value, and if no value is specified, an equivalent value is inferred dynamically based on the value of the Format property.
06/27/20238578RESTAdded
  • The OAuthJWTHeaders property has been added, allowing customers to define custom JWT headers.

  • Added the Default column to the sys_procedureparameters table.
12/09/20228378RESTAdded
  • Added the WriteToFile parameter for CreateSchema. This defaults to true and must be disabled to write the schema to FileStream or FileData.

Removed
  • Removed the FileLocation parameter from CreateSchema. The Location property must be used to set the output directory for created schemas.
10/31/20228339RESTAdded
  • Added support the RefreshOAuth operation which can be used to refresh authentication on long-running queries. It is intended for use where a single script triggers multiple network requests to APIs that use OAuth. It may be invoked with 
    <api:call op="utiladoRefreshOAuth" />
    .
10/27/20228335RESTAdded
  • Added support for using PKCE with the authorization code OAuth grant type.
10/12/20228320TableauAdded

  • Added the IsPath column to the sys_procedureparameters table.
08/30/20228277RESTAdded
  • Added support for uploading server-side encrypted objects for Amazon S3 storage source via ServerSideEncryption connection property.
08/12/20228259TableauChanged
  • 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.
03/15/20228109RESTAdded
  • Added support for using JWT with generic http:// sources. Previously it was only available for specific types of sources like gdrive://. Custom JWT is currently only supported for authorization grants, not client credentials.
03/09/20228103RESTChanged
  • 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.
03/01/20228095RESTAdded
  • Added support for CSV. This is available using Format=CSV or the csvprovideropsGet script operation. This also adds the FMT and IncludeColumnHeaders options for accepting different kinds of CSV data.
01/07/20228042RESTAdded
  • Added support the sleep operation which can be used to add delays to table operations. This is intended for use with async APIs built around polling. It may be invoked with 
    <api:call op="utiladoSleep?timeout=x" />
    where x is the delay in seconds.
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.
06/24/20217845RESTAdded
  • 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.
06/08/20217829RESTAdded
  • Added support for the AzureServicePrinciple authentication scheme, which will support both using an OAuthClientSecret, or alternatively using a JWT cert.
06/05/20217826RESTAdded
  • 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.
04/23/20217783RESTDeprecated
  • 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.
04/16/20217776TableauChanged
  • Improved the connection dialog configuration experience.
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.
03/26/20217755RESTChanged (JSON+XML)
  • Updated the way default table names are computed so that the file name is taken The provider will now consistently use the following values when naming the table that uses the root XPath. In order:
    • The value of the roottablename input attribute, if given.
    • The value of the TableName connection property, if given. This is a new property for XML and its functonality is the same as the JSON property of the same name.
    • 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/.xml"), or the URI is for HTTP/HTTPS then the URI is ignored.
    • The value "XMLData" or "JSONData", depending on the format.
  • This change does not apply when the connection is in backwards compatibility mode.
12/21/20207660RESTAdded (JSON)
  • 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)

Added (XML)
  • Add support for reporting special types for aggregates. If the user opts in via SupportNativeDataType and are using JDBC, then the driver will report XML as the type name for aggregate columns (nlike JSON there is no XMLArray / XMLObject distinction)
