Connection String Generator creates a ready-to-use connection string that allows a third-party application to connect to a SQL Server instance.
Product version: That's some Java code example to establish database connection to Microsoft SQL Server.The Connection String Generator tool helps you build a SQL connection string, eliminating the need to research and memorize all the available options.
}The program would produce the following output: Driver name: Microsoft JDBC Driver 8.2 for SQL Server ("Product version: " + dm.getDatabaseProductVersion()) ("Product name: " + dm.getDatabaseProductName()) ("Driver version: " + dm.getDriverVersion()) String dbURL = "jdbc:sqlserver://localhost\\sqlexpress" Ĭonn = DriverManager.getConnection(dbURL, user, pass) ĭatabaseMetaData dm = (DatabaseMetaData) conn.getMetaData()
* This program demonstrates how to establish database connection to Microsoft Java Code Example to connect to SQL ServerTo demonstrate, we create a small program that connects to an SQL Server instance on localhost and print out some database information as follows: package Properties properties = new Properties() Ĭonn = DriverManager.getConnection(dbURL, properties) NOTE: if you want to use Windows authentication mode ( integratedSecurity=true), you must have the sqljdbc_auth.dll in the classpath.Ĥ. }The following code passes username and password as arguments to the method getConnection(): String dbURL = "jdbc:sqlserver://localhost\\sqlexpress" Ĭonn = DriverManager.getConnection(dbURL, user, pass) We can also use a object to store connection properties, as in the following example: String dbURL = "jdbc:sqlserver://localhost\\sqlexpress" Here is a code snippet that connects the user sa with password secret to the instance sqlexpress on localhost: String dbURL = "jdbc:sqlserver://localhost\\sqlexpress user=sa password=secret" Ĭonnection conn = DriverManager.getConnection(dbURL) Register JDBC driver for SQL Server and establish connectionThe JDBC driver class of SQL Server is .SQLServerDriver, so to register this driver, use the following statement: DriverManager.registerDriver(new .SQLServerDriver()) Or: Class.forName(".SQLServerDriver") However, that is not required since JDBC 4.0 (JDK 6.0) because the driver manager can detect and load the driver class automatically as long as a suitable JDBC driver present in the classpath.To make a connection, call the method getConnection() of the DriverManager class. Jdbc:sqlserver://localhost:1433 databaseName=testdb integratedSecurity=true ģ. Connect to a named database testdb on localhost using Windows authentication: Jdbc:sqlserver://dbHost\sqlexpress user=sa password=secret Connect to an instance named sqlexpress on the host dbServer, using SQL Server authentication: Jdbc:sqlserver://localhost integratedSecurity=true Connect to default instance of SQL server running on the same machine as the JDBC client, using Windows authentication: We have to specify username and password explicitly for this mode. SQL Server authentication: using a SQL Server account to authenticate.We specify this mode by adding the property integratedSecurity=true to the URL. This mode is for the case both the client and the SQL server are running on the same machine. Windows authentication: using current Windows user account to log on SQL Server.
NOTE: SQL Server has two authentication modes: To see the properties specific to SQL server, visit Setting the Connection Properties.
property=value: specify one or more additional connection properties.If this parameter is missing, the default port is used. portNumber: port number of SQL server, default is 1433.The default instance is used if this parameter is not specified. instanceName: name of the instance to connect to on serverName.serverName: host name or IP address of the machine on which SQL server is running.JDBC database URL for SQL ServerThe syntax of database URL for SQL Server is as follows: jdbc:sqlserver:// ]] If you use Maven, then declare the following dependency:
