New features in 12.8

Feature	Details
Java 22 support	The driver is now compatible with Java Development Kit (JDK) version 22.0 in addition to JDK 21.0, 17.0, 11.0 and 1.8.
Added credential caching when using Managed Identity Credential or Default Azure Credential	In order to improve performance and driver reliability, the driver now allows caching of the previously mentioned credentials.
Allow caching of the `SQLServerBulkCopy` object when using bulk copy for batch insert	Replaces previous behavior, where each call of `executeBatch()` generated a new `SQLServerBulkCopy` object, by caching the object instead.
Added connection level caching for destination column metadate in bulk copy	Improves performance by adding caching at the connection level for destination column metadata in bulk copy scenarios. This feature is enabled by setting the newly added connection string property `cacheBulkCopyMetadata` to `true` (default value is `false`).
Added a SQL Server message handler and support for SQLException chaining	Added a SQL Server message handler allowing for several features including extra feedback for long running queries, universal error logging, and automatic downgrade of error-message severity from SQLException to SQLWarning. Additionally, this feature allows for chaining of SQLExceptions together so that all error messages are available to the user. See Handling Errors.
Provided full support for RFC4180 for CSV bulk insert operations	Support for quoted fields containing newlines were missing in order to ensure full support with RFC4180; this support is now added.
Allow constructing a `microsoft.sql.DateTimeOffset` instance from a `java.time.OffsetDateTime` value	Conversion between the two data types already existed in the driver using a `Timestamp` intermediary. This addition removes that intermediary, improving performance and reducing the potential for timezone-related errors.

Changes in 12.8

Change	Details
Enum `SQLServerSortOrder` is now public	Changed visibility of the enum `SQLServerSortOrder` to public, which allows users greater flexibility in queries that use this enum.
Remove `synchronized` from Socket overrides	Incorrectly added in prior changes to confirm with code check standards, the select methods changed don't, in fact, need to be synchronized, and are changed to reflect this fact.
Revised previous RMERR/RMFAIL changes by making the default `RMFAIL`	Prior changes changed the value of `XAER_RMFAIL` to `XAER_RMERR` for select cases, however these cases quickly became most of all cases covered. The solution is to change the default to `RMFAIL` and convert to `RMERR` for inverse of previously stated cases.
Updated dependencies	Updated dependency versions for `azure-identity`, `bouncycastle`, and `msal`.
Revised support for `TDSType.GUID`	Enhances the original addition of support for `TDSType.GUID` by allowing direct passage of the UUID to the `setObject` method.
Added logging to token caching	Added more logging for token caching scenarios to help in debug scenarios.

Fixes in 12.8

Fix	Details
Fixed regression with specifying argument names in callable statement syntax	Fixed a regression from 12.6.2 --> 12.6.3 where CallableStatements of a certain format returned incorrect values. GitHub Issue #2477.
Fixed parsing for parentheses in stored procedures and functions	Fix for an issue where calling a function with parentheses at the end in a callable statement, for example, function() vs function, resulting in the return value always being 0. This change was a regression from 12.6.2 --> 12.6.3. GitHub Issue #2463.
Fixed an error where the driver wasn't respecting `CallableStatement` with default arguments.	Fixed an error that was a regression from 12.5.0 --> 12.6.0, where default arguments in callable statements were being ignored. GitHub Issue #2446.
Fix to remove `TokenCredential` class where the driver doesn't require it	`TokenCredentialClass` isn't needed in `SQLServerSecurityUtility` and can cause an incorrectly thrown `NoClassDefFoundError`. This fix removes the import, replacing it with a generic `Object`. GitHub Issue #2439.
Fixed timestamp string conversion error for CallableStatements	Fixed a conversion exception that occurred when calling a `DateTime` in/out parameter while setting a `String` value. GitHub Issue #2436.
Fixed SqlAuthenticationToken constructor to accept correct parameter	The constructor for SQLAuthenticationToken was incorrect, working with an input parameter in seconds, when it should be milliseconds. GitHub Issue #2424.
Fix to clear prepared statement handle before reconnection	This fixes an issue where the wrong handles were used in a `SQLServerPreparedStatement` after reconnection by properly clearing `SQLServerPreparedStatement.prepStmtHandle` before reconnecting. GitHub Issue #2364.
Fix to clear prepared statement cache when resetting statement pool connection	This fixes an issue where, with statement pooling enabled, reusing a connection from a ConnectionPool resulted in missing, or incorrectly inserted, entries. GitHub Issue #2356.
Fix to unbind `socketTimeout` from `loginTimeout`	`socketTimeout` should have an upper-bound of `loginTimeout` for connection establishment, but should have no upper-bound after the driver is connected. This change fixes that behavior. GitHub Issue #2354.
Fix to properly check if `TDSCommand` counter is null before attempting to increment	Adds a missing `null` check for the `TDSCommand` counter, preventing a `NullPointerException` that could otherwise arise. GitHub Issue #2353.
Fix calling procedures with output parameters by their four-part syntax	Fixes an issue where calling stored procedures with a four-part syntax (that is, with a linked server) resulted in an error stating the TDS protocol stream isn't valid. GitHub Issue #2344.
Fix to properly escape `schema` parameters for `getProcedures` and `getProcedureColumns`	The `SQLServerDatabaseMetadata` methods `getProcedures` and `getProcedureColumns` weren't properly escaping certain characters (for example, `\`) for the `schema` parameter. This change fixes that issue. GitHub Issue #2336.
Added token cache map to fix use of unintended auth token for subsequent connections	This fixes an issue where client credentials could be inadvertently reused. While the auth token was correctly cached, the driver was reusing the token with only the client secret changed. GitHub Issue #2334.
Fixed support for `exec` escape syntax in CallableStatements	This fixes an issue where, after removing the wrapped `sp_executesql`/`sp_prepexec` calls in order to execute CallableStatements quickly, `EXEC` calls were no longer working. GitHub Issue #2325.
Fix to ensure `Money` and `SmallMoney` are within the correct ranges for bulk copy	This fixes an issue where, when using bulk copy with `Money` or `SmallMoney` values, conversion to/from the values can cause an `ArithmeticOverflowException`. GitHub Issue #2309.
Fix to ensure `ResultSetMetadata` for `DataabseMetadata.getColumns()` is correct for all columns	The returned metadata was incorrect for some columns, this change fixes that problem. GitHub Issue #2232.
Fix to properly turn off connection retries when `connectRetryCount` is set to `0`	This fixes the behavior where, even with `connectRetryCount` set to 0, the driver attempted to retry until `loginTimeout` was reached. GitHub Issue #2232. GitHub Issue #2188.
Fix to address a `ClassLoader` leak of `ActivityCorrelator` `ThreadLocal`	Fixes an issue where, after previous driver changes to `ActivityId`, `ThreadLocal` in `ActivityCorrelator` is never being removed from the thread.
Fix to execute stored procedures directly for RPC calls	RPC calls were using prior logic by being wrapped in `sp_executesql` calls; this change fixes that behavior.

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 calls 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 extra 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 use the Redirection logging category, and can be used at the FINE logging level. Idle connection resiliency reconnects use 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 more errors that should translate to RMFAIL	Added more cases, "connection reset by peer" and "connection timed out," that should equate to RMFAIL
Changed how Timestamps are used in bulk copy	Change bulk copy behavior from serializing and deserializing Timestamp objects, to using the objects directly, leading to a performance improvement when a user is using many Timestamps.
Changed `socketTimeout` to ensure it's properly less than `loginTimeout`	Previously `socketTimeout` acted independently from `loginTimeout` leading to potentially confusing behavior where the driver would take longer to time out than expected. This issue is fixed so `socketTimeout` always has an upper bound equal to `loginTimeout`.
Adjusted the PreparedStatement cache so it clears itself 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()	Fix for 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.
Fix for an issue with Timestamps and bulk copy for batch insert	Fixed timezone not being properly applied to Timestamps when inserted using batch insert with bulk copy. GitHub Issue #2271.
Fixed missing getters and setters for `useBulkCopyForBatchInsert`	Fix for an issue where behavior wasn't 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 bulk copy metadata query to make use of cached data, if available	Fix for 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	Fix for an issue where, when writing TVP row values, input values weren't properly filtered for BigDecimal scale. GitHub Issue #2222.
Fixed schemaPattern in SQLServerDatabaseMetadata to ensure methods that use the parameter properly escape it.	Fix for an issue where schemaPattern was the only pattern not properly being escaped in SQLServerDatabaseMetadata. GitHub Issue #2186.
Fix for an issue where a null SQLState was returned when trying to convert a date to a long	Fix for an issue where, when `xopenStates` is set to true, the driver doesn't return the expected SQL-99 state code in a particular instance. GitHub Issue #2167.
Fixed getMetaData error for queries containing TOP	Fix for 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	Fix for an issue where insert statements with missing whitespace worked correctly in regular cases, but not when using batch inserts. GitHub Issue #1534.
Fix for an issue with ParameterMetadata and invalid indexes	Fix for 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 bulk copy for batch insert	Fixed bulk copy 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	Fix for an issue where the driver wasn't properly verifying the signature, when using Java Key Store, and 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	Fix for 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.

Fixes in 12.4

Fix	Details
Fixed performance and memory issues present with BigDecimal	Reverts all changes, since the 12.2 release, regarding BigDecimal. This fix addresses the performance issues that were observed. Users need to take care when using BigDecimal to avoid the truncation issues that were previously addressed. GitHub Issue #2176.
Fixed server certificate validation for encrypt=strict	Fix to ensure the server certificate is properly validated in cases where `encrypt` is set to `strict`. GitHub Issue #2174.
Fixed lockTimeout not taking effect when redirect mode is set in Azure DB	Fixed when `lockTimeout` is set, as it should only apply to connections from outside Azure, and not from within Azure, as was previously. GitHub Issue #2110.
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	Fix for an issue where, if `metaQuery` returned no result after execution of a stored procedure, this issue would return a parameter undefined error. GitHub Issue #2063.
Fixed invalid batch inserts when columns provided in insert differs in order from table schema	Fix for 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	Fix for an issue where, the driver would return XAException with error code XAER_RMERR if there was 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. Also fixed client ID to persist for the life of the process.

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 release 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.

6.0

Download Microsoft JDBC Driver 6.0 for SQL Server (self-extracting exe)
Download Microsoft JDBC Driver 6.0 for SQL Server (tar.gz)

Version number: 6.0.8112
Released: January 17, 2017

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.
