String url = "jdbc: db2: ch"; // This format is jdbc: Sub-Protocol: Sub-name, where ch is the database name
String user = "db2inst1"; // Database Connector ID
String password = "db2inst1"; // Database Connector password
DriverManager. registerDriver (new COM. ibm. db2.jdbc. app. DB2Driver ());
// This sentence is the most important. Like DB2 and ORACLE, it is best to create a drive instance explicitly and register it with the drive manager.
// Other databases generally use Class. forName ("xxxxxxxxxxx ");
Connection conn = null;
Try {
Conn = DriverManager. getConnection (url, user, password );
Statement stmt = conn. createStatement (); // create a database connection object
String SQL = "select * from task ";
ResultSet rs1_stmt.exe cuteQuery (SQL );
