Connect to Microsoft SQL Server via JDBCDetails Last Updated on 0. August 2. 01. 7 | Print Email. Table of content: Download Microsoft JDBC driver. JDBC database URL for SQL Server. Register JDBC driver for SQL Server and establish connection. ![]() Value Description; 0: SQL is sent to the server each time without any preparation, literals are inserted in the SQL (slower) 1: Temporary stored procedures are. Is it possible to connect to a SQL Server LocalDB using JDBC? Not with Microsoft's JDBC Driver. The jTDS JDBC driver supports named pipes. Executing SqlLocalDB.exe.
![]() Example program This article describes how to get JDBC driver and write code for making database connection to Microsoft SQL Server from a Java client. Suppose you have a light weight version of SQL Server installed, such as Microsoft SQL Server 2. Express. 1. Download Microsoft JDBC driver. Click here to download Microsoft JDBC Driver 4. SQL Server which supports: SQL Server versions: 2. R2, and 2. 01. 2. JDK version: 5. 0 and 6. Run the downloaded program sqljdbc_< version> _< language>. It will extract the files into a specified directory (default is Microsoft JDBC Driver 4. SQL Server). You will find two jar files sqljdbc. JDBC 3. 0) and sqljdbc. JDBC 4. 0), plus some . HTML help files. Place the sqljdbc. JDK 5. 0 or sqljdbc. JDK 6. 0 or later. Recommended Book: Introducing Microsoft SQL Server 2. JDBC database URL for SQL Server The syntax of database URL for SQL Server is as follows: jdbc: sqlserver: //[server. Name[\instance. Name][: port. Number]][; property=value[; property=value]]Where: server. Name: host name or IP address of the machine on which SQL server is running. Name: name of the instance to connect to on server. Name. The default instance is used if this parameter is not specified. Number: port number of SQL server, default is 1. If this parameter is missing, the default port is used. To see the properties specific to SQL server, visit Setting the Connection Properties. NOTE: SQL Server has two authentication modes: Windows authentication: using current Windows user account to log on SQL Server. This mode is for the case both the client and the SQL server are running on the same machine. We specify this mode by adding the property integrated. Security=true to the URL. SQL Server authentication: using a SQL Server account to authenticate. We have to specify username and password explicitly for this mode. Following are some examples: - Connect to default instance of SQL server running on the same machine as the JDBC client, using Windows authentication: jdbc: sqlserver: //localhost; integrated. Security=true; - Connect to an instance named sqlexpress on the host db. Server, using SQL Server authentication: jdbc: sqlserver: //db. Host\sqlexpress; user=sa; password=secret- Connect to a named database testdb on localhost using Windows authentication: jdbc: sqlserver: //localhost: 1. Name=testdb; integrated. Security=true; Recommended Book: Microsoft SQL Server 2. T- SQL Fundamentals. Register JDBC driver for SQL Server and establish connection The JDBC driver class of SQL Server is com. SQLServer. Driver, so to register this driver, use the following statement: Driver. Manager. register. Driver(new com. microsoft. SQLServer. Driver()). Or: Class. for. Name("com. SQLServer. Driver"). However, that is not required since JDBC 4. JDK 6. 0) because the driver manager can detect and load the driver class automatically as long as the sqljdbc. To make a connection, call the method get. Connection() of the Driver. Manager class. Here is a code snippet that connects the user sa with password secret to the instance sqlexpress on localhost: String db. URL = "jdbc: sqlserver: //localhost\\sqlexpress; user=sa; password=secret". Connection conn = Driver. Manager. get. Connection(db. URL). if (conn != null) {. System. out. println("Connected"). The following code passes username and password as arguments to the method get. Connection(): String db. URL = "jdbc: sqlserver: //localhost\\sqlexpress". String user = "sa". String pass = "secret". Driver. Manager. get. Connection(db. URL, user, pass). We can also use a java. Properties object to store connection properties, as in the following example: String db. URL = "jdbc: sqlserver: //localhost\\sqlexpress". Properties properties = new Properties(). Driver. Manager. get. Connection(db. URL, properties). NOTE: if you want to use Windows authentication mode (integrated. Security=true), you must have the sqljdbc_auth. Example program To demonstrate, we create a small program that connects to an SQL Server instance on localhost and print out some database information as follows: package net. Connection. import java. Database. Meta. Data. Driver. Manager. import java. SQLException. * This program demonstrates how to establish database connection to Microsoft. Jdbc. SQLServer. Connection {. String[] args) {. Connection conn = null. String db. URL = "jdbc: sqlserver: //localhost\\sqlexpress". String user = "sa". String pass = "secret". Driver. Manager. get. Connection(db. URL, user, pass). Database. Meta. Data dm = (Database. Meta. Data) conn. Meta. Data(). System. Driver name: " + dm. Driver. Name()). System. Driver version: " + dm. Driver. Version()). System. out. println("Product name: " + dm. Database. Product. Name()). System. out. Product version: " + dm. Database. Product. Version()). } catch (SQLException ex) {. Stack. Trace(). if (conn != null & & ! Closed()) {. conn. SQLException ex) {. Stack. Trace(). The program would produce the following output: Driver name: Microsoft JDBC Driver 4. SQL Server. Driver version: 4. Product name: Microsoft SQL Server. Product version: 1. Related Tutorial: You may be also interested in. SQL Server Central. Microsoft SQL Server tutorials, training & forum.
