Microsoft JDBC Driver for SQL Server

Welcome to the Microsoft JDBC Driver for SQL Server project!

The Microsoft JDBC Driver for SQL Server is a Type 4 JDBC driver that provides database connectivity through the standard JDBC application program interfaces (APIs) available in the Java Platform, Enterprise Editions. The Driver provides access to Microsoft SQL Server and Azure SQL Database from any Java application, application server, or Java-enabled applet.

We hope you enjoy using the Microsoft JDBC Driver for SQL Server.

Get Started

Build

Prerequisites

Java 11+
Maven 3.5.0+
An instance of SQL Server or Azure SQL Database that you can connect to.

Build the JAR files

Maven builds automatically trigger a set of verification tests to run. For these tests to pass, you will first need to add an environment variable in your system called mssql_jdbc_test_connection_properties to provide the correct connection properties for your SQL Server or Azure SQL Database instance.

To build the jar files, you must use minimum version of Java 11 with Maven. You may choose to build JDBC 4.3 compliant jar file (for use with JRE 11 or newer JRE versions) and/or a JDBC 4.2 compliant jar file (for use with JRE 8).

Maven:
1. If you have not already done so, add the environment variable mssql_jdbc_test_connection_properties in your system with the connection properties for your SQL Server or SQL DB instance.
2. Run one of the commands below to build a JRE 11 and newer versions compatible jar or JRE 8 compatible jar in the \target directory.
  - Run mvn install -Pjre13. This creates JRE 13 compatible jar in \target directory which is JDBC 4.3 compliant (Build with JDK 13+).
  - Run mvn install -Pjre11. This creates JRE 11 compatible jar in \target directory which is JDBC 4.3 compliant (Build with JDK 11+).
  - Run mvn install -Pjre8. This creates JRE 8 compatible jar in \target directory which is JDBC 4.2 compliant (Build with JDK 11+).
Gradle:
1. If you have not already done so, add the environment variable mssql_jdbc_test_connection_properties in your system with the connection properties for your SQL Server or SQL DB instance.
2. Run one of the commands below to build a JRE 11 and newer versions compatible jar or JRE 8 compatible jar in the \build\libs directory.
  - Run gradle build -PbuildProfile=jre13. This creates JRE 13 compatible jar in \build\libs directory which is JDBC 4.3 compliant (Build with JDK 13+).
  - Run gradle build -PbuildProfile=jre11. This creates JRE 11 compatible jar in \build\libs directory which is JDBC 4.3 compliant (Build with JDK 11+).
  - Run gradle build -PbuildProfile=jre8. This creates JRE 8 compatible jar in \build\libs directory which is JDBC 4.2 compliant (Build with JDK 11+).

Azure Key Vault and Azure Active Directory Authentication Dependencies

Projects that require either of the two features need to explicitly declare the dependency in their pom file.

For Example: If you are using Azure Active Directory Authentication feature then you need to redeclare adal4j and client-runtime dependency in your project's POM file. Please see the following snippet:

<dependency>
	<groupId>com.microsoft.sqlserver</groupId>
	<artifactId>mssql-jdbc</artifactId>
	<version>8.1.1.jre13-preview</version>
	<scope>compile</scope>
</dependency>

<dependency>
	<groupId>com.microsoft.azure</groupId>
	<artifactId>adal4j</artifactId>
	<version>1.6.4</version>
</dependency>

<dependency>
	<groupId>com.microsoft.rest</groupId>
	<artifactId>client-runtime</artifactId>
	<version>1.6.15</version>
</dependency>

For Example: If you are using Azure Key Vault feature then you need to redeclare azure-keyvault, azure-keyvault-webkey dependency and adal4j, client-runtime dependency in your project's POM file. Please see the following snippet:

<dependency>
	<groupId>com.microsoft.sqlserver</groupId>
	<artifactId>mssql-jdbc</artifactId>
	<version>8.1.1.jre13-preview</version>
	<scope>compile</scope>
</dependency>

<dependency>
	<groupId>com.microsoft.azure</groupId>
	<artifactId>adal4j</artifactId>
	<version>1.6.4</version>
</dependency>

<dependency>
	<groupId>com.microsoft.rest</groupId>
	<artifactId>client-runtime</artifactId>
	<version>1.6.15</version>
</dependency>

<dependency>
	<groupId>com.microsoft.azure</groupId>
	<artifactId>azure-keyvault</artifactId>
	<version>1.2.2</version>
</dependency>

Please note as of the v6.2.2, the way to construct a SQLServerColumnEncryptionAzureKeyVaultProvider object has changed. Please refer to this Wiki page for more information.

'useFmtOnly' connection property Dependencies

When setting 'useFmtOnly' property to 'true' for establishing a connection or creating a prepared statement, antlr-runtime dependency is required to be added in your project's POM file. Please see the following snippet:

<dependency>
	<groupId>com.microsoft.sqlserver</groupId>
	<artifactId>mssql-jdbc</artifactId>
	<version>8.1.1.jre13-preview</version>

Guidelines for Reporting Issues

We appreciate you taking the time to test the driver, provide feedback and report any issues. It would be extremely helpful if you:

Report each issue as a new issue (but check first if it's already been reported)
Try to be detailed in your report. Useful information for good bug reports include:
- What you are seeing and what the expected behavior is
- Which jar file?
- Environment details: e.g. Java version, client operating system?
- Table schema (for some issues the data types make a big difference!)
- Any other relevant information you want to share
Try to include a Java sample demonstrating the isolated problem.

Thank you!

Reporting security issues and security bugs

Security issues and bugs should be reported privately, via email, to the Microsoft Security Response Center (MSRC) secure@microsoft.com. You should receive a response within 24 hours. If for some reason you do not, please follow up via email to ensure we received your original message. Further information, including the MSRC PGP key, can be found in the Security TechCenter.

Release roadmap and standards

Our goal is to release regular updates which improve the driver and bring new features to users. Stable, production quality releases happen twice a year, targeting the first and third quarters of the calendar year. They are tested against a comprehensive matrix of supported operating systems, Java versions, and SQL Server versions. Stable releases are accompanied by additional localized packages, which are available on the Microsoft website.

Preview releases happen approximately monthly between stable releases. This gives users an opportunity to try out new features and provide feedback on them before they go into stable releases. Preview releases also include frequent bug fixes for customers to verify without having to wait for a stable release. Preview releases are only available in English. While they are tested, preview releases do not necessarily go through the same rigorous, full test matrix and review process as stable releases.

You can see what is going into a future release by monitoring Milestones in the repository.

Version conventions

Starting with 6.0, stable versions have an even minor version. For example, 6.0, 6.2, 6.4, 7.0, 7.2, 7.4. Preview versions have an odd minor version. For example, 6.1, 6.3, 6.5, 7.1, 7.3, 8.1 and so on
