Java JDBC调用Oracle,Java中调用代码3:
- Class.forName("oracle.jdbc.driver.OracleDriver");
- conn = DriverManager.getConnection("jdbc:oracle:thin:@127.0.0.1:1521:orcl","scott","tiger");
- conn.setAutoCommit(false);
-
- conn=DBConnection.getDBConnection().getConnection();
-
- String spName="{call sp_add_emp2(?,?,?,?,?)}";
- CallableStatement cstmt=conn.prepareCall(spName);
- cstmt.setInt(1,1111);
- cstmt.setString(2, "qqqq");
- cstmt.setInt(3, 50);
- cstmt.setString(4, "pppp");
- cstmt.registerOutParameter(5, java.sql.Types.ORACLETYPE);
- cstmt.executeUpdate();
- int i = cstmt.getInt(5);
- System.out.println(i);
- cstmt.close();
- conn.close();
