MySQL CONCAT(“string”,longtext) results in hex string

Question

I\'m experiencing a weird hex string result when trying to concat a string with a column that should be of LONGTEXT type.

The query goes like this:

S         


        

Answer 1

When you concat a number without a cast it returns as a blob. This is intended functionality of MySQL as far as I can tell since, it was reported in this bug thread and they closed it and confirmed it was returning a Blob.

Answer 2

Have you tried casting? Usually works pretty well for me. Example:

SELECT CONCAT("abc",CAST(t.LONGTEXT_VALUE AS CHAR),"cde") FROM mytable t
