New features in 12.6

Feature Details
Java 21 support The driver is now compatible with Java Development Kit (JDK) version 21.0 in addition to JDK 17.0, 11.0 and 1.8.
Allow calling of stored procedures directly through use of new connection property useFlexibleCallableStatements The driver now call store procedures directly, as opposed to wrapping the procedure around exec sp_executesql, simplifying the procedure and improving performance.
Added useDefaultJaasConfig connection string property When set to true, allows Kerberos authentication without additional external configuration.
Added useDefaultGSSCredential connection string property When set to true, allows the driver to create GSSCredential on behalf of the user, when using Native GSS-API for Kerberos authentication.
Added calcBigDecimalPrecision connection string property When set to true, allows the driver to calculate precision for BigDecimal inputs.
Added new named loggers for connection open retries and idle connection resiliency reconnects Connection open retries uses the Redirection logging category, and can be used at the FINE logging level. Idle connection resiliency reconnects uses the Resiliency logging category, and can be used at the FINE or FINER logging levels.

Changes in 12.6

Change Details
Changed how IBM JDK is checked for prevent issues with OSGi environments Changed from only checking vendor name, to checking both vendor and vm name.
Properly synchronized all calls to MSAL Prevents the driver from making extra calls and proving unnecessary dialogues.
Added additional errors that should translate to RMFAIL Added additional cases, "connection reset by peer" and "connection timed out", that should equate to RMFAIL
Changed how Timestamps are used in BulkCopy Change BulkCopy behavior from serializing and deserializing Timestamp objects, to using the objects directly, leading to a performance improvement when using a large number of Timestamps.
Changed socketTimeout to ensure it's properly less than loginTimeout Previously socketTimeout acted independetly from loginTimeout leading to potentially confusing behavior where the driver would take longer to timeout than expected. This has been fixed so socketTimeout always has an upper bound equal to loginTimeout.
Adjusted PreparedStatement cache so it's cleared before every execute The PreparedStatement cache wasn't being cleared correctly, which, in addition to its infrequency, could lead to memory issues over time. This change ensures the cache is cleaned before each execute, preventing object build-up.
Upgraded to newer Bouncycastle dependencies Upgrade from bcprov-jdk15on and bcpkix-jdk15on to bcprov-jdk18on and bcpkix-jdk18on as the former is no longer being updated.
Updated dependencies Updated dependency versions for azure-identity, azure-security-keyvault-keys, bouncycastle, h2 and msal.

Fixes in 12.6

Fix Details
Fixed a missing null check for e.getCause() Fixed an issue where, when an exception has no cause, the exception itself is passed along instead, preventing it from being lost. GitHub Issue #2299.
Fixed locks in IOBuffer to prevent deadlock issues that could arise Fixed implementation of locks in IOBuffer, specifically around disableSSL, to prevent deadlocks that could arise in certain situations. GitHub Issue #2288. GitHub Issue #2265.
Fixed an issue with Timestamps and bulk copy for batch insert Fixed timezone not being properly applied to Timestamps when inserted using batch insert with bulkcopy. GitHub Issue #2271.
Fixed missing getters and setters for useBulkCopyForBatchInsert Fixed an issue where behavior was not the same between SQLServerConnection and SQLServerConnnectionPoolProxy, when it should be, as useBulkCopyForBatchInsert was missing a getter and setter in the latter. GitHub Issue #2245.
Fixed bulkcopy metadata query to make use of cached data, if available Fixed an issue where, despite the data being cached, calls for column metadata were being called each time. GitHub Issue #2224.
Fixed a missing BigDecimal scale check for TVP values - Fixed an issue where, when writing TVP row values, input values were not properly filtered for BigDecimal scale. GitHub Issue #2222.
Fixed schemaPattern in SQLServerDatabaseMetadata to ensure its properly escaped Fixed an issue where schemaPattern was the only pattern not properly being escaped in SQLServerDatabaseMetadata. GitHub Issue #2186.
Fixed an issue where a null SQLState was returned when trying to convert a date to a long Fixed an issue where, when xopenStates is set to true, the driver does not return the expected SQL-99 state code in a particular instance. GitHub Issue #2167.
Fixed getMetaData error for queries containing TOP Fixed an issue where, when using the TOP qualifier in a query, the driver returns an error concerning ParameterMetadata. GitHub Issue #1776.
Fixed a table name parsing issue when using batch inserts Fixed an issue where insert statements with missing whitespace worked correctly in regular cases, but not when using batch inserts. GitHub Issue #1534.
Fixed an issue with ParameterMetadata and invalid indexes Fixed an issue with ParameterMetadata not properly checking, and throwing exceptions for, an invalid index 0. GitHub Issue #1490.
Fixed behavior of ActivityID in ActivityCorrelator Fixed the way ActivityID was defined and used to be more in line with the behavior of other Microsoft drivers.
Fix to ignore computed columns when using bulkcopy for batch insert Fixed BulkCopy behavior to ignore computed columns, and allow batch inserts, when previously the insert would fail and return an error citing those computed columns.
Fixed driver behavior concerning signatures when using Java Key Store and Azure Key Vault Fixed an issue where signature was not properly verfied when using Java Key Store, as well as adding a new API to sign column master key metadata (and return generated signature) for use with Java Key Store and Azure Key Vault
Fixes getObject()'s erroneous conversion of DateTimeOffset Fixed an issue when calling ResultSet.getObject() on a DATETIMEOFFSET column, with LocalDate/LocalTime/LocalDateTime as the class argument, the value in the column would be converted to the local time zone.

Fixed high thread count when using findSocketUsingThreading Fixes an issue where an uncaught exception led to interruption in sleep calls upstream, causing retries to happen too quickly. GitHub Issue #2104.
Fixed shared timer race condition Fixed a potential race condition in the SharedTimer class. GitHub Issue #2085.
Fixed an error with stored procedures and zero result metaQuery return Fixed an issue where, if metaQuery returned no result after execution of a stored procedure, this would return a parameter undefined error. GitHub Issue #2063.
Fixed invalid batch inserts when columns provided in insert differs in order from table schema Fixed an issue where usage of useBulkCopyForBatchInsert=true can lead to column mix-up and invalid data. GitHub Issue #1992.
Fixed XA error handling to rethrow XAER_RMFAIL instead of XAER_RMERR Fixed an issue where, the driver would return XAException with error code XAER_RMERR in case of failover of SQL Server from primary node to standby node while committing an XA Transaction. GitHub Issue #1432.
Fixes to Activity ID and Client ID behavior to maintain consistency with JDBC specification Fixed Activity ID behavior to stay the same for the life of the process, always send Activity ID in PRELOGIN, and increment sequence for each new connection.

The driver supports JDK version 9.0 in addition to JDK 8.0 and 7.0.

JDBC 4.3 compliance

The driver supports the Java Database Connectivity API 4.3 specification, in addition to 4.1 and 4.2. The JDBC 4.3 API methods are added but not implemented yet. For details, see JDBC 4.3 compliance for the JDBC Driver.

Added connection property: sslProtocol

A new connection property lets users specify the TLS protocol keyword. Possible values are: "TLS", "TLSv1", "TLSv1.1", and "TLSv1.2". For details, see SSLProtocol.

Deprecated connection property: fipsProvider

The connection property fipsProvider is removed from the list of accepted connection properties. For details, see the related GitHub pull request.

Added connection properties for specifying a custom TrustManager

The driver now supports specifying a custom TrustManager with added trustManagerClass and trustManagerConstructorArg connection properties. You can dynamically specify a set of certificates that are trusted on a per-connection basis without modifying the global settings for the Java virtual machine (JVM) environment.

Added support for datetime/smallDatetime in table-valued parameters

The driver now supports the datatypes datetime and smallDatetime when you're using table-valued parameters (TVPs).

Added support for the sql_variant datatype

The JDBC Driver now supports sql_variant datatypes to be used with SQL Server. The sql_variant datatype is also supported with features such as TVPs and bulk copy with the following limitations:

  • For date values:

    When you're using a TVP to populate a table that contains datetime, smalldatetime, or date values stored in a sql_variant column, calling the getDateTime(), getSmallDateTime(), or getDate() method on the result set doesn't work and throws the following exception:

    java java.lang.String cannot be cast to java.sql.Timestamp

    As a workaround, use the getString() or getObject() method instead.

  • Using a TVP with sql_variant for null values:

    If you're using a TVP to populate a table and send a NULL value to the sql_variant column type, you encounter an exception. Inserting a NULL value with the column type sql_variant in a TVP is currently not supported.

Implemented prepared statement metadata caching

The JDBC Driver has implemented prepared statement metadata caching for performance improvement. The driver now supports caching prepared statement metadata in the driver with disableStatementPooling and statementPoolingCacheSize connection properties. This feature is disabled by default. For more information, see Prepared statement metadata caching for the JDBC Driver.

Added support for Azure AD Integrated Authentication on Linux/macOS

The JDBC Driver now supports Azure Active Directory (Azure AD) Integrated Authentication on all supported operating systems (Windows, Linux, and macOS) with Kerberos. Alternatively, on Windows operating systems, users can authenticate with mssql-jdbc_auth-<version>-<arch>.dll.

Updated "Microsoft Azure Active Directory Authentication Library (ADAL4J) for Java" version: 1.4.0

The JDBC Driver has updated its Maven dependency on "Microsoft Azure Active Directory Authentication Library (ADAL4J) for Java" to version 1.4.0. For more information about dependencies, see Feature dependencies of the Microsoft JDBC Driver for SQL Server.

Azure AD support for Linux

Connect your Linux applications to Azure SQL Database by using Azure AD authentication via username/password and access token methods.

FIPS-enabled JVMs

The JDBC Driver can now be used on JVMs that run in Federal Information Processing Standard (FIPS) 140 compliance mode to meet federal standards on compliance.

Kerberos authentication improvements

The JDBC Driver now has support for:

  • Principal/password method for applications where the Kerberos configuration can't be modified or can't retrieve a new token or keytab. This method can be used for authenticating to a SQL Server instance that allows only Kerberos authentication.
  • Cross-realm authentication that uses Kerberos Integrated Authentication without explicitly setting the server SPN. The driver now automatically computes the realm even when it isn't provided.
  • Kerberos Constrained Delegation by accepting impersonated user credentials as a GSS credential object via data source. This impersonated credential is then used to establish a Kerberos connection.

Added timeouts

The JDBC Driver now supports the following configurable timeouts. You can change them based on your application's needs.

  • Query timeout to control the number of seconds to wait before a timeout occurs when you're running a query.
  • Socket timeout to specify the number of milliseconds to wait before a timeout occurs on a socket read or accept.

6.1

Version number: 6.1.0
Released: November 17, 2016

Microsoft JDBC Driver 6.1 for SQL Server is fully compliant with JDBC specifications 4.1 and 4.2. This is the initial open-source release of the JDBC Driver. The source code can be found at the GitHub v6.1.0 tag. It builds the mssql-jdbc-6.1.0.jre8.jar and mssql-jdbc-6.1.0.jre7.jar files, which correspond to Java version compatibility.

Microsoft JDBC Driver 6.0 for SQL Server is fully compliant with JDBC specifications 4.1 and 4.2. The jars in the 6.0 package are named according to their compliance with the JDBC API version. For example, the sqljdbc42.jar file from the 6.0 package is JDBC API 4.2 compliant. Similarly, the sqljdbc41.jar file is compliant with JDBC API 4.1.

To ensure that you have the right sqljdbc42.jar or sqljdbc41.jar file, run the following lines of code. If the output is "Driver version: 6.0.7507.100", you have the JDBC Driver 6.0 package.

Connection conn = DriverManager.getConnection("jdbc:sqlserver://<server>;encrypt=true;user=<user>;password=<password>;");
System.out.println("Driver version: " + conn.getMetaData().getDriverVersion());

Always Encrypted

The driver supports the Always Encrypted feature in SQL Server 2016. This feature ensures that sensitive data is never seen in plaintext in a SQL Server instance. Always Encrypted works by transparently encrypting the data in the application, so that SQL Server handles only the encrypted data and not plaintext values. Even if the SQL Server instance or the host machine is compromised, all an attacker can get is ciphertext of sensitive data. For details, see Using Always Encrypted with the JDBC Driver.

Internationalized domain names

The driver supports internationalized domain names (IDNs) for server names. For details, see "Using International Domain Names" in the International features of the JDBC Driver article.

Parameterized queries

The driver now supports retrieving parameter metadata with prepared statements for complex queries, such as subqueries and/or joins. This improvement is available only when you're using SQL Server 2012 and newer versions.

Azure Active Directory

Azure AD authentication is a mechanism of connecting to Azure SQL Database using identities in Azure AD. Use Azure AD authentication to centrally manage identities of database users and as an alternative to SQL Server authentication.

You can use JDBC Driver 6.0 to specify your Azure AD credentials in the JDBC connection string to connect to Azure SQL Database. For details, see the authentication property in the Setting the connection properties article.

Table-valued parameters

TVPs provide an easy way to marshal multiple rows of data from a client application to SQL Server without requiring multiple round trips or special server-side logic for processing the data. You can use TVPs to encapsulate rows of data in a client application and send the data to the server in a single parameterized command. The incoming data rows are stored in a table variable that you can then operate on by using Transact-SQL. For details, see Using table-valued parameters.

Always On Availability Groups

The driver now supports transparent connections to Always On Availability Groups. The driver quickly discovers the current Always On topology of your server infrastructure and connects to the current active server transparently.
