标签归档:ORA-01465
ORA-01465: invalid hex number
网友反馈blob插入一些字段报错,查询metalink,发现使用rawtohex处理即可,测试如下:
SQL> create table t_lob (t blob); Table created. SQL> insert into t_lob values('-------'); insert into t_lob values('-------') * ERROR at line 1: ORA-01465: invalid hex number SQL> insert into t_lob values(rawtohex('---------')); 1 row created. SQL> insert into t_lob values('----------&'); insert into t_lob values('----------&') * ERROR at line 1: ORA-01465: invalid hex number SQL> insert into t_lob values(rawtohex('----------&')); 1 row created. SQL> commit; Commit complete.
网友提供java处理代码如下:
///插入 public void test() { conn=DBUtil.getActiveConnection(); String sqlStr="Set define off"; String ss="————"; String sql="insert into test1(names,btestname) values('12',rawtohex('"+ss+"'))"; System.out.println(sqlStr); System.out.println(sql); try { pstmt=conn.prepareStatement(sqlStr); pstmt.addBatch(); pstmt=conn.prepareStatement(sql); pstmt.addBatch(); pstmt.executeBatch(); } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } finally { DBUtil.closeStatement(pstmt); DBUtil.closeConnection(conn); } } ////查询语句 public void getTest() { conn=DBUtil.getActiveConnection(); String sql="select * from test1 where names='12'"; //oracle.sql.BLOB blob = null; InputStream inStream=null; try { pstmt=conn.prepareStatement(sql); set=pstmt.executeQuery(); if(set!=null && set.next()) { //接收blob类型 java.sql.Blob blob = (oracle.sql.BLOB)set.getBlob("btestname"); //注意 inStream = blob.getBinaryStream(); if(blob!=null) System.out.println("有值============"); try { byte[] data = new byte[200]; int length=0;//每次读取的实际字节长度 //is.read()方法:从buff缓中区的第0个位开始读取字节,每次最多读取200, //方法会返回一个实际读取的长度,用length接收,当值为-1时,表示所有的字节全部读取完毕 while((length=inStream.read(data,0,200))!=-1) { //把字节以平台的默认编码方式转为字符,从buff的第0个位开始转换,实际要转换的长度是length String str=new String(data,0,length); System.out.println("最终结果==== "+str+" ===="); } //关闭流 inStream.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } finally { DBUtil.closeResultSet(set); DBUtil.closeStatement(pstmt); DBUtil.closeConnection(conn); } }
