Chapter 7, Page 239: Aes_Decrypt Table Results Shows As Blob In Pin Field

Recommended Posts

Scripts 1, 2 and 3 from page 238 all work fine. When I run script 4 on page 239 and run:


SELECT 8 FROM customers WHERE customer_id=1;


the table displays 'BLOB' in the pin field rather than the expected '1234'.


I did look up BLOB erros and my character set is definately utf8 with collation utf8 general ci.
