  • Added support for document() function.
12/14/20228383GeneralChanged
  • Added the Default column to the sys_procedureparameters table.
09/30/20228308GeneralChanged
  • Added the IsPath column to the sys_procedureparameters table.
09/22/20228300Amazon DynamoDBAdded
  • Added the FileStream output for the CreateSchema stored procedure. An instance of an output stream where file data is written to. Only used if FileName is not set.
08/19/20228266Amazon DynamoDBAdded
  • Added the FileData output for the CreateSchema stored procedure. It pushes the generated schema encoded in Base64 only if the FileName input is not set.
08/17/20228264GeneralChanged
  • We now support handling the keyword "COLLATE" as standard function name as well.
06/11/20228197jdbcChanged
  • The method GetJDBCMinorVersion() and GetJDBCMajorVersion() return 4.2 as the supported JDBC major / minor version.
04/28/20228153jdbcChanged
  • Removed support for JRE 1.6. JRE 1.8 and above is now required.
03/16/20228110Amazon DynamoDBAdded
  • Added support for Instance Metadata Service Version 2 (IMDSv2) when authenticating from an Amazon EC2 instance.
03/02/20228096Amazon DynamoDBAdded
  • Added support for the AutoDetectIndex connection property.

Changed
  • In DynamoDB, secondary indexes can be used to more quickly select data from a given table. By default, we now attempt to automatically detect an index to use based on the query criteria. To turn off index detecting logic, simply set the AutoDetectIndex connection property to false. Alternatively, you may use the SecondaryIndexName pseudo column to specify which index to use (if any).
03/01/20228095Amazon DynamoDBAdded
  • Add support for the AwsCognitoBasic and AwsCognitoSrp authentication methods.
02/25/20228091jdbcChanged
  • The method DatabaseMetaData.getTypeInfo() now returns all the data types the driver supports. Previously it was returning only a portion of the data types. The returns types include: tinyint, smallint, int, bigint, float, double, numeric, decimal, bit, date, datetime, time, varchar, binary, uuid.
02/24/20228090jdbcChanged
  • Correct the return value of method DatabaseMetaData.supportsOuterJoins(), it used to return the wrong value.
10/27/20217970jdbcChanged
  • Support for JDK 17
09/12/20217925jdbcRemoved
  • Removed IS_READONLY, IS_KEY, NUMERIC_PRECISION, DECIMAL_DIGITS from DatabaseMetadata.GetColumns() as they are not part of the JDBC Specification. This information is still available via other metadata calls.
09/08/20217923Amazon DynamoDBAdded
  • Added support for PartiQL statements. Driver now utilizes the ExecuteStatement API operation to execute PartiQL statements, which offers better support for executing filters on the query server side.
  • Added support for BULK UPDATE operations.

Changed
  • The DynamoDB JSON document parser is re-written to fully support all the levels of structure nesting and indexing or un-nesting at all levels.
  • Data type auto discovery mechanism to properly detect datetime fields.
  • Fixed vertical flattening on primitive arrays.
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 vs te predicate. Ie: 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. Ie: WHERE col > L_LAST_MONTH(). This will continue to resolve to the same values that previously were calculated in the criteria. Note that the "L_" prefix will only work in the predicate - it not available for the projection.
07/08/20217859GeneralAdded
  • Added the TCP Logging Module for the logging information happening on the TCP wire protocol. The transport bytes that are incoming and ongoing will be logged at verbosity=5.
05/17/20217807Amazon DynamoDBAdded
  • Added support for Single Sign On (SSO) connection with PingFederate as the Identity Provider (IdP).
04/23/20217785GeneralAdded
  • 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

Changed
  • Reduced the length to 255 for varchar primary key and foreign key columns.
  • Updated implicit and metadata caching to improve performance and support for multiple connections. Old metadata caches are not compatible - you would need to generate new metadata caches if you are currently using CacheMetadata.
  • Updated index naming convention to avoid duplicates
  • Updated and standardized Getting Started connection help.
  • Added the Advanced Features section to the help of all drivers.
  • Categorized connection property listings in the help for all editions.
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
