sql - creating a random blob in jdbc and writing it to oracle -

i want create many blobs in java [in memory] , write oracle table.

what want blob[bits inside it] random or sudo random oracle not able lot of pre-optimization while storing blob table.

something

for(1..1000000) { blob = createrandomblob(sizeofblob); sqltext ="insert test_blob (id, blob) values(i, blob)"; stmt.executeupdate(sqltext); } 

can point java apis can use create such blob[in memory rather on disk] , write db ?

thanks

i think should trick

  byte[] data = new byte[10000];     frandom.nextbytes(data);     try     {       serialblob fserialblob = new serialblob(data);     } catch (serialexception e)     {       // todo auto-generated catch block       e.printstacktrace();     } catch (sqlexception e)     {       // todo auto-generated catch block       e.printstacktrace();     } 

dont know if there faster/efficient way of doing it.
