jdbc 对sqlite的基本操作

1.向数据库中创建表

public void addTable( String dbpath)
	{

//创建表单的sql语句
	
	String createtablesql= " CREATE TABLE T_AFAF_AREA(PID TEXT,STDNAME TEXT) ";
	//这里的TEXT 类型根据需要改变
    try{
		    Class.forName("org.sqlite.JDBC");
		    Connection conn = DriverManager.getConnection("jdbc:sqlite:"+dbpath);   
		    Statement stmt = conn.createStatement();
		    //巡检表
                   stmt.executeUpdate(createtablesql);
	}catch(Exception e)
		{
			e.printStackTrace();
		}
	}

2.从 .db 文件中删除表

这里只贴出来语句其他都一样

//判断巡检表是否存在 存在 则删除
	    String deletetablesql = " drop table  if exists T_EXAMINEDATA  ";

3 . 从 .db 文件中读取信息

public List <TStreetsExamine> queryTStreetsExamine(String dbpath)
	{
		List <TStreetsExamine> list = new ArrayList<TStreetsExamine>();
		try{
		    Class.forName("org.sqlite.JDBC");
		    Connection conn = DriverManager.getConnection("jdbc:sqlite:"+dbpath);   
			Statement stmt = conn.createStatement();
			ResultSet res = stmt.executeQuery(" select * from T_STREETS_SURVEY    ");
			while(res.next())
			{
				//公共部分
				String pid =	res.getString("PID");
	//......................................这里省略n行					 list.add(te);
			}
			res.close();
			stmt.close();
			res.close();
		}
		catch(Exception e)
		{ 
			e.printStackTrace();
		}
		
		return list;
		
	}

4.向.db文件中写入数据

public void addStreets(TStreets te ,String dbpath)
	{
		try{

		    Class.forName("org.sqlite.JDBC");
		    Connection conn = DriverManager.getConnection("jdbc:sqlite:"+"E://toponymsurvey11122.db");   
			 Statement stmt = conn.createStatement();
			 PreparedStatement pstmt = null ;	// 数据库操作
		          String sql = " INSERT INTO T_STREETS(PID ,STDENAME) VALUES (?,?)  " ;
                        pstmt = conn.prepareStatement(sql) ;
	                 pstmt.setString(1,te.getPid()) ;
			 pstmt.setString(2,te.getStdname()) ;
		         pstmt.executeUpdate() ;	// 执行更新
			 pstmt.close() ;
			 stmt.close();
			 conn.close();
		}catch(Exception e)
		{
			e.printStackTrace();
			
		}
	}
