SQL Query with binary data (PHP and MySQL)

Question

This site had helped me a lot in the past, but now I am lost. Thanks in advance for your guidance.

I have a MySQL table that contains a Binary value, like the exampl

Answer 1

Note: This addresses binary data, but not encrypted data. See this answer for searching on encrypted data.

Try adding X, x or 0x in front of binary data used for search:

SELECT id FROM test WHERE pid = '0xÞFÈ>ZPÎ×jRZ{æ×';

EDIT: try also this:

SELECT id FROM test WHERE BINARY pid = 'ÞFÈ>ZPÎ×jRZ{æ×';

OR

SELECT id FROM test WHERE HEX(pid) = BIN2HEX('0xÞFÈ>ZPÎ×jRZ{æ×');

as supposed here: How to select with a binary field ? (php,mysql)

IF NOTHING FROM ABOVE WORKS: Try obtaining the pid in HEX format, like

SELECT id, HEX(pid) pid, test FROM test

and then when searching try only:

SELECT id, test FROM test WHERE HEX(pid) = '{$my_pid}'

But I'm not sure how do You obtain the pid data to PHP or even whether You pass the binary data into Your select - where query... Just guessing due to the php tag...

Answer 2

try:

X''   --Hex Content

mysql> SELECT x'4D7953514C'；
    -> 'MySQL'

Answer 3

The last posting from jixiang pointed me into the right direction for searching a binary field:

SELECT * FROM test WHERE yourBinaryColumn = x'binarystuffdata';

This works for me...

Answer 4

For me it works without quotes in the binary field

SELECT * FROM `clients_addresses` WHERE client_id = 0x4f8472e23e63404fb8f9f56
