How to convert BLOB object to PL Json - json
i am using below code to load image file from server to BLOB Object
but after convert it to clob and put it into json it reformatted.
how can i fix this
FUNCTION get_person_image(v_file_name varchar2) RETURN json AS
tmp_blob blob default EMPTY_BLOB();
tmp_bfile bfile := null;
dest_offset integer := 1;
src_offset integer := 1;
v_ret_json json := json();
BEGIN
tmp_bfile := BFILENAME('PICTURES', v_file_name);
DBMS_LOB.OPEN(tmp_bfile, DBMS_LOB.FILE_READONLY);
DBMS_LOB.CREATETEMPORARY(tmp_blob, TRUE);
DBMS_LOB.LOADBLOBFROMFILE(tmp_blob,
tmp_bfile,
DBMS_LOB.LOBMAXSIZE,
dest_offset,
src_offset);
DBMS_LOB.CLOSE(tmp_bfile);
v_ret_json.put('name', v_file_name);
v_ret_json.put('image', blob_to_clob(tmp_blob));
RETURN v_ret_json;
END get_person_image;
FUNCTION blob_to_clob(blob_in IN BLOB) RETURN CLOB AS
v_clob CLOB;
v_varchar VARCHAR2(32767);
v_start PLS_INTEGER := 1;
v_buffer PLS_INTEGER := 32767;
begin
DBMS_LOB.CREATETEMPORARY(v_clob, TRUE);
FOR i IN 1 .. CEIL(DBMS_LOB.GETLENGTH(blob_in) / v_buffer) LOOP
v_varchar := UTL_RAW.CAST_TO_VARCHAR2(DBMS_LOB.SUBSTR(blob_in,
v_buffer,
v_start));
DBMS_LOB.WRITEAPPEND(v_clob, LENGTH(v_varchar), v_varchar);
v_start := v_start + v_buffer;
END LOOP;
RETURN v_clob;
END blob_to_clob;
Once the get_person_image read image file the CLOB Contains data like below HEX:

and when i open as text in PLSQL it is something like this :

after v_ret_json.put('image', blob_to_clob(tmp_blob)); it reformatted as :

Unknown compression method
Can someone explain me, what is that compression method used? I tried to reverse engeneer old application. It using tcp connection and send messages using json. All data was the plain json, but that data is json value "pb_rsp" was binary and i cant uncompress that. 120113837000265, Xanthus, EliteDog, flag30, 574949063200274 - thats a plain data. Around them some unknown separators. I think thats encoded json, but cant detect method, help please � 9181129d4be64c36ad42401c8227226f�� "Z 120113837000265Xanthus *8

When getting a hexadecimal dump in VS, what do those periods mean?
For example: %PDF-1.3..%..... ...1 0 obj..<<.. from 25 50 44 46 2D 31 2E 33 0D 0A 25 E2 E3 CF D3 0D 0A 0D 0A 31 20 30 20 6F 62 6A 0D 0A 3C 3C 0D 0A Do they represent numbers that don't fit in ASCII?

Change default Sorting by Adding a Simple Collation to an 8-Bit Character Set
Posted previously the question with zero responses, so I am replacing it with further clarification and details from my research results based on this MySQL manual entry. In the past, I've worked with alternate collations that allowed us to specify alternate default sorting. Mysql allows for this down to the column level, but I don't understand something to get it working. Our customers use a standard set of one character codes in almost all references to any master table, and presenting these codes in the order they need is always very cumbersome and difficult using functions and routines in PHP. SELECT * FROM myTable order by my_code NORMAL, default sorting would return this: DESIRED, default sorting should return this: my_code | Description my_code | Description 1 | Grade 1 P | Pre-Kindergarten 2 | Grade 2 K | Kindergarten 3 | Grade 3 1 | Grade 1 A | Adult 2 | Grade 2 K | Kindergarten 3 | Grade 3 P | Pre-Kindergarten A | Adult The steps to accomplish this are described in the Docs at 10.4.3. , and examples are shown in the Docs at 10.1.78. In the steps, it shows this table, and how the weights are specified. This, I think is where I get lost. I've altered the weights as shown below, putting "P" (x50P) and "K" (x4B) before "0" (x30), but all it accomplishes is changing the sorting so that "1" (x31) appears between "P" and "K", all other sorting appears to remain unchanged. <collation name="latin1_test_ci"> <map> 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 20 21 22 23 24 25 26 27 28 29 2A 2B 2C 2D 2E 2F 50 4B 30 31 32 33 34 35 36 37 38 39 41 43 55 3A 3B 3C 3D 3E 3F 40 42 44 45 46 47 48 49 4A 4C 4D 4E 4F 51 52 53 54 56 57 58 59 5A 5B 5C 5D 5E 5F 60 41 42 43 44 45 46 47 48 49 4A 4B 4C 4D 4E 4F 50 51 52 53 54 55 56 57 58 59 5A 7B 7C 7D 7E 7F 80 81 82 83 84 85 86 87 88 89 8A 8B 8C 8D 8E 8F 90 91 92 93 94 95 96 97 98 99 9A 9B 9C 9D 9E 9F A0 A1 A2 A3 A4 A5 A6 A7 A8 A9 AA AB AC AD AE AF B0 B1 B2 B3 B4 B5 B6 B7 B8 B9 BA BB BC BD BE BF 41 41 41 41 5C 5B 5C 43 45 45 45 45 49 49 49 49 44 4E 4F 4F 4F 4F 5D D7 D8 55 55 55 59 59 DE DF 41 41 41 41 5C 5B 5C 43 45 45 45 45 49 49 49 49 44 4E 4F 4F 4F 4F 5D F7 D8 55 55 55 59 59 DE FF </map> </collation> Sort results WITH the Alternate Collation above Hex |my_code | Description 32 | 2 |Grade 2 33 | 3 |Grade 3 41 | A |Adult Ed 4B | K |Kindergarten 31 | 1 |Grade 1 50 | P |Pre-K
I realize you said you wanted to change the collation, but this requires no ORDER BY and is worth considering. You can convert these to an ENUM type and they will sort in the order they appear in the ENUM.
CREATE TABLE myTable (
my_code ENUM('P', 'K', '1', '2', '3', 'A'),
...
)
Using numbers in ENUMs is strongly discouraged, so you'll have to be careful. The main issue is that numbers can be treated as an index or a value in the ENUM. So it's behavior depends on it's type, leading to unexpected results.
This table are weights table. If you want that P i less than K, then put 00 weight to P and 01 weight to K. To put a weight you should assign a value in 'letter position': for P position 50. Sample to put P as first order letter:

I don't think you need a custom collation to accomplish your goals.
To order the result set:
ORDER BY FIELD(my_code, 'P','K','1','2','3','4','5','6',
'7','8','9','10','11','12','A')
To limit the result set:
WHERE my_code IN('K','1','2','3','4','5')
If you'll be writing this sort of functionality into a lot of queries, a helper function might be a good idea:
DELIMITER $$
CREATE FUNCTION `f_position`(in_char CHAR(1)) RETURNS INTEGER
BEGIN
RETURN FIELD(in_char, 'P','K','1','2','3','4','5','6',
'7','8','9','10','11','12','A');
END$$
DELIMITER ;
Just make sure that all possible codes are referenced in the function, and are placed in the order that you want.
With a helper function like that, you can write queries like so:
WHERE f_position(grade) BETWEEN f_position('K') AND f_position('5')
ORDER BY f_position(grade)
The only downside to using a helper function to limit result sets like that (as opposed to the WHERE grade IN(...)) is that the function call would prevent any indexes on the column "grade" from being used.
