SQL count - not working

Question

I am trying this code:

SELECT COUNT (oferta_id_oferta)  FROM `oferta_has_tags`  WHERE oferta_id_oferta =  (SELECT id_oferta FROM oferta  WHERE oferta = "designer") 

I receive error: 1630 - FUNCTION mydb.COUNT does not exist. Check the 'Function Name Parsing and Resolution' section in the Reference Manual

If I remove the COUNT word, I get two results.

What is the problem?

Answer 1

Don't put a space

SELECT COUNT(oferta_id_oferta)  FROM `oferta_has_tags`  WHERE oferta_id_oferta =  (SELECT id_oferta FROM oferta  WHERE oferta = "designer") 

Answer 2

Try removing the space between COUNT and the parentheses:

SELECT COUNT(oferta_id_oferta)  FROM `oferta_has_tags`  WHERE oferta_id_oferta =  (SELECT id_oferta FROM oferta  WHERE oferta = "designer") 

Also, you can probably get rid of your subquery by joining:

SELECT COUNT(oferta_id_oferta)  FROM `oferta_has_tags`, `oferta` WHERE     oferta_has_tags.oferta_id_oferta = oferta.id_oferta     AND oferta.oferta = "designer"
