MySql SELECT statement with where LIKE not returning results

Question

MySql statement does not return any results when I include WHERE LIKE .

Statement:

SELECT aes_decrypt(SchoolName, 'MyString') as SchoolName from SchoolList Where aes_decrypt(SchoolName, 'MyString') LIKE '% Part of School Name Here%'

If I remove the LIKE it works

SELECT aes_decrypt(SchoolName, 'MyString') as SchoolName from SchoolList Where aes_decrypt(SchoolName, 'MyString') = 'School Name Here'

Answer 1

You need to cast the result of aes_decrypt to char in order to use LIKE operator:

SELECT aes_decrypt(SchoolName, 'MyString') as SchoolName 
from SchoolList 
Where cast(aes_decrypt(SchoolName, 'MyString') as CHAR) LIKE '% Part of School Name Here%'
