java oracle clob转string 文心快码 在Java中将Oracle数据库中的CLOB(Character Large Object)数据类型转换为String,可以通过几种不同的方法实现。下面将详细介绍这些方法,并提供相应的代码示例。 1. 使用BufferedReader逐行读取CLOB数据 这种方法通过获取CLOB的字符流,并使用BufferedReader逐行读取数据,最后拼接成完整的...
private String clobToString(Clob clob){ String res= ""; Reader is = clob.getCharacterStream(); BufferedReader br = new BufferedReader(is); String s = br.readLine(); StringBuffer sb = new StringBuffer(); while (s != null) { sb.append(s); s = br.readLine(); } res= sb.toString(...
在Java获取Oracle中CLOB字段转换成String的方法寺至如下 public String ClobToString(Clob clob) throws SQLException, IOException { String reString = ""; Reader is = clob.getCharacterStream();// 得到流 BufferedReader br = new BufferedReader(is); String s = br.readLine(); StringBuffer sb = new Str...
java获取oracle中CLOB字段,转换成String try{PreparedStatementstmt=session.connection().prepareStatement(sql);ResultSetrs=stmt.executeQuery();while(rs.next()){Clobclob=(Clob)rs.getObject(1);result=ClobToString(clob);}}catch(HibernateExceptione){e.printStackTrace();}catch(SQLExceptione){e.printStackTrace...
1.执行clob转String public static String ClobToString(Clob sc) throws SQLException, IOException { String reString = ""; Reader is = sc.getCharacterStream(); // 得到流 BufferedReader br = new BufferedReader(is); String s = br.readLine(); ...
Java读取Oracle的CLOB字段转换为String数据 其中Clob 类型转换为String的自定义方法如下 代码语言:javascript 代码运行次数:0 运行 AI代码解释 privateStringclob2String(Clob clob)throws SQLException,IOException{String reString="";Reader is=clob.getCharacterStream();// 得到流BufferedReader br=newBufferedReader(is...
java获取oracle中CLOB字段,转换成String try { PreparedStatement stmt = session.connection().prepareStatement(sql); ResultSet rs = stmt.executeQuery(); while (rs.next()) { Clob clob = (Clob)rs.getObject(1); result = ClobToString(clob);
如果使用oracle的话，直接将clob字段读取为string；也就是下面这一行:clob = (oracle.sql.clob)rs.getobject(1);可以直接写成 string str = rs.getstring(1);get
