What are the common ways to connect to JDBC databases? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

1. JDBC connects to DB2

Class.forName ("Com.ibm.db2.jdbc.net.DB2Driver"); String url= "jdbc:db2://dburl:port/DBname" cn = DriverManager.getConnection (url, sUsr, sPwd)

2. JDBC connects to Microsoft SQLServer (microsoft)

Class.forName ("com.microsoft.jdbc.sqlserver.SQLServerDriver"); cn = DriverManager.getConnection ("jdbc:microsoft:sqlserver://DBServerIP:1433;databaseName=master", sUsr, sPwd)

3. JDBC connects to Sybase (jconn2.jar)

Class.forName ("com.sybase.jdbc2.jdbc.SybDriver"); cn = DriverManager.getConnection ("jdbc:sybase:Tds:DBServerIP:2638", sUsr, sPwd)

4. JDBC connects to MySQL (mm.mysql-3.0.2-bin.jar)

Class.forName ("org.gjt.mm.mysql.Driver"); cn = DriverManager.getConnection ("jdbc:mysql://DBServerIP:3306/myDatabaseName", sUsr, sPwd)

5. JDBC connection PostgreSQL (pgjdbc2.jar)

Class.forName ("org.postgresql.Driver"); cn = DriverManager.getConnection ("jdbc:postgresql://DBServerIP/myDatabaseName", sUsr, sPwd)

6. JDBC connects to Oracle (classes12.jar)

Class.forName ("oracle.jdbc.driver.OracleDriver"); cn = DriverManager.getConnection ("jdbc:oracle:thin:@MyDbComputerNameOrIP:1521:ORCL", sUsr, sPwd)

7. JDBC connects to ODBC

Class.forName ("sun.jdbc.odbc.JdbcOdbcDriver"); Connection cn = DriverManager.getConnection ("jdbc:odbc:" + sDsn, sUsr, sPwd)

The jdbc connection method for some databases is not fixed, depending on the driver package you use.

For example, mssql's jtdsjar package:

Database URL:jdbc:jtds:sqlserver://localhost:1433;DatabaseName=XXX

Driver class: net.sourceforge.jtds.jdbc.Driver

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 (); / or Class.forName ("com.mysql.jdbc.Driver"); 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)

8. ODBC is directly connected to access database.

Class.forName ("sun.jdbc.odbc.JdbcOdbcDriver"); String url= "jdbc:odbc:Driver= {MicroSoft Access Driver (* .mdb)}; DBQ=" + application.getRealPath ("/ Data/ReportDemo.mdb"); Connection conn = DriverManager.getConnection (url, ",").
