如何将字节数组存入Oracle

1、如果是插入数据，先插入一个empty_blob()，更新数据就update为empty_blob

2、然后select 一次，获得该 blob

3、然后调用

1、try{

conn = this.getConnection();

conn.setAutoCommit(false);

java.sql.Statement st = conn.createStatement();

String sql1 = “insert into test_image(test_id,image) values (“123”,empty_blob)”;

System.out.println(“———>”+sql1);

String stl2 = “select image from test_image where test_id=’”+test.getId()+”’ for update”;

ResultSet rs = st.executeQuery(stl2);

OutputStream outStream = null;

if (rs.next())

{

oracle.sql.BLOB blob = (oracle.sql.BLOB) rs.getBlob(“image”);

outStream = blob.getBinaryOutputStream();

outStream.write(byte[],0, byte[].length);

}

outStream.flush();

outStream.close();

conn.commit();

conn.close();

}
