This article mainly explains "how Java connects to various databases". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn "what is the way Java connects to various databases"?

1. Oracle8/8i/9i database (thin mode)

Class.forName ("oracle.jdbc.driver.OracleDriver"). NewInstance (); String url= "jdbc:oracle:thin:@localhost:1521:orcl"; / / orcl is the SID String user= "test" of the database; String password= "test"; Connection conn= DriverManager.getConnection (url,user,password)

2. DB2 database

Class.forName ("com.ibm.db2.jdbc.app.DB2Driver"). NewInstance (); String url= "jdbc:db2://localhost:5000/sample"; / / sample is your database name String user= "admin"; String password= ""; Connection conn= DriverManager.getConnection (url,user,password)

3. Sql Server7.0/2000 database

Class.forName ("com.microsoft.jdbc.sqlserver.SQLServerDriver"). NewInstance (); String url= "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=mydb"; / / mydb is the database String user= "sa"; String password= ""; Connection conn= DriverManager.getConnection (url,user,password)

4. Sybase database

Class.forName ("com.sybase.jdbc.SybDriver"). NewInstance (); String url = "jdbc:sybase:Tds:localhost:5007/myDB"; / / myDB is your database name Properties sysProps = System.getProperties (); SysProps.put ("user", "userid"); SysProps.put ("password", "user_password"); Connection conn= DriverManager.getConnection (url, SysProps)

5. Informix database

Class.forName ("com.informix.jdbc.IfxDriver"). NewInstance (); String url = "jdbc:informix-sqli://123.45.67.89:1533/myDB:INFORMIXSERVER=myserver; user=testuser;password=testpassword"; / / myDB is the database name Connection conn= DriverManager.getConnection (url)

6. MySQL database

Class.forName ("org.gjt.mm.mysql.Driver"). NewInstance (); String url = "jdbc:mysql://localhost/myDB?user=soft&password=soft1234&useUnicode=true&characterEncoding=8859_1" / / myDB is the database name Connection conn= DriverManager.getConnection (url)

7. PostgreSQL database

Class.forName ("org.postgresql.Driver"). NewInstance (); String url = "jdbc:postgresql://localhost/myDB" / / myDB is the database name String user= "myuser"; String password= "mypassword"; Connection conn= DriverManager.getConnection (url,user,password); at this point, I believe you have a deeper understanding of "how Java connects to various databases".
