I want to concatenate 2 strings in my mysql database and I get the error message:
ERROR 1305 (42000): FUNCTION support.concat does not exist
How is that possible?


In some mysql versions, you MUST NOT have a space after the function name. Try concat() instead of concat ().

mysql> update s_resources set resource_path = concat (resource_path, '/');
ERROR 1305 (42000): FUNCTION support.concat does not exist

mysql> update s_resources set resource_path = concat(resource_path, '/');
Query OK, 6 rows affected (0.00 sec)
Rows matched: 6  Changed: 6  Warnings: 0

Very helpful, I have been using CONCAT() for a while but I guess I had never left a space after it. After chasing that error for two days I found this post Thank you very much.

Thanks very much, it helped me with a stupid error I got:

Error: MySQL says: FUNCTION database_name.round does not exist

which I found difficult to identify (since I am a C++ programmer).

Still helpful! A nextline-character i.s.o. a space had the same effect.
