Does CodeName One support MYSQL BLOBs using RESTful Database Interface? - mysql

Question

Using CodenameOne web database extension, I can get basic SQL fields to work for strings and numbers, but not for large binary objects BLOBs. I'm following the instructions here: https://www.codenameone.com/blog/connecting-to-a-mysql-database-part-2.html
Are BLOBs supported by CodenameOne? If so how do you do it? I can't find any examples that use BLOB types.
I've tried using long strings, and with the MarianaDB, can get up to 512K string size, but I need to store images which can be larger.
MariaDB [(none)]> use tsg; desc photos;
Database changed
+------------+------------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+------------+------------------+------+-----+---------+----------------+
| id | int(10) unsigned | NO | PRI | NULL | auto_increment |
| player_id | int(11) | NO | | NULL | |
| tree_id | int(11) | NO | | NULL | |
| photo_type | longtext | NO | | NULL | |
| image | blob | YES | | NULL | |

5 rows in set (0.001 sec)
When I add the record without the blob it works:
m.put("playerId", "1");
m.put("treeId", "2");
m.put("photoType", "front");
m.put("image", null);
client.create(m, res -> {
System.out.println(m);
System.out.println("create result = " + res);
});
outputs:
{treeId=2, image=null, photoType=front, playerId=1}
create result = true
But when I try to add the blob, it does not:
m.put("playerId", "1");
m.put("treeId", "2");
m.put("photoType", "front");
byte bytes[] = new byte[100];
m.put("image", bytes);
client.create(m, res -> {
System.out.println(m);
System.out.println("create result = " + res);
});
outputs:
{treeId=2, image=[B#5968c8cb, photoType=front, playerId=1}
create result = false
Help! I'm using BLOBs in the wrong way, or does CN1 not support BLOBs?
The only error message is from the result of create being false.

It doesn't have builtin support for that at this time. You can use MultipartRequest to submit binary data to the server.
