java存储过程调用例子

存储过程调用

Connectin conn = DBUtil.getConnection(); DatabaseMetaData dbmd = conn.getMetaData(); //获取数据库数据元 //获取存储过程的参数列表 ResultSet rs = dbmd.getProcedureColumns(packageName, "", procedure, null); while(rs.next()){ String columnName=rs.getString(" COLUMN_NAME");//获取参数名称 int columnType = rs.getInt(" COLUMN_TYPE");//获取参数类型 in dateType = rs.getInt(" DATA_TYPE");//获取参数数据类型 } String sql = "{call procedureName(p1=>?,p2=>?,p3=>?,p4=>?)}"; CallableStatement call=conn. prepareCall(sql);//获取存储过程对象 call.setObject(1,obj1);//传入参数 call.setObject(2,obj1); call.registerOutParameter(2,obj2_sql_type);//声明返回数据类型 call.registerOutParameter(3,obj3_sql_type); call.registerOutParameter(4,obj4_sql_type); call.execute();//调用存储过程 Object val2= call.getObject(2);//获取返回参数值 Object val3=call.getObject(3); Object val4=call.getObject(4); call.commit();//提交 call.close();//关闭 rs.close(); conn.close();
