Implementation for JDBC 4.3 introduced java.sql.Connection APIs beginRequest() and endRequest()

Microsoft JDBC Driver 7.0 for SQL Server now implements beginRequest() and endRequest() APIs from the java.sql.Connection class. These APIs were introduced with JDBC 4.3 specifications and JDK 9. For more information about the driver's implementation of these APIs, see JDBC 4.3 compliance for the JDBC Driver.

Support for SQL Data Discovery and Classification

Microsoft JDBC Driver 7.0 for SQL Server provides support for SQL Data Discovery and Classification with any target database that supports this feature. The driver now exposes SQLServerResultSet.getSensitivityClassification() APIs to extract this information from the fetched ResultSet.

For more information about how to use this feature with the JDBC Driver, see the sample in SQL Data Discovery and Classification.

Added connection property: useBulkCopyForBatchInsert

Microsoft JDBC Driver 7.0 for SQL Server introduces a new connection property, useBulkCopyForBatchInsert. This property is supported only for Azure Synapse Analytics.

This property is disabled by default. You can enable it to increase performance of user applications when you're pushing large amounts data to Azure Synapse Analytics. Enabling this property changes the behavior of batch insert operations to switch to bulk copy operations with user-provided data. For more information about this property and its limitations, see Using Bulk Copy API for batch insert operation.

Added connection property: cancelQueryTimeout

Microsoft JDBC Driver 7.0 for SQL Server introduces a new connection property, cancelQueryTimeout, to cancel queryTimeout on java.sql.Connection and java.sql.Statement objects.

Added Azure Key Vault Provider constructors

Microsoft JDBC Driver 7.0 for SQL Server reintroduces a previously removed constructor, for SQLServerColumnEncryptionAzureKeyVaultProvider. It allowed authentication through a custom method implemented over SQLServerKeyVaultAuthenticationCallback to fetch an access token.

The new constructors have the following definition:

/* This constructor is added to provide backward compatibility with 6.0
* version of the driver. It is marked deprecated for removal in the next
* stable release.
*/
@Deprecated
public SQLServerColumnEncryptionAzureKeyVaultProvider(
        SQLServerKeyVaultAuthenticationCallback authenticationCallback,
        ExecutorService executorService) throws SQLServerException;

/*New constructor to replace the above constructor*/
public SQLServerColumnEncryptionAzureKeyVaultProvider(
            SQLServerKeyVaultAuthenticationCallback authenticationCallback) throws SQLServerException;

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'll 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.

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

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 will handle 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. Note that 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.
