Question

I found a very similar quesiton on here copied the code changed as required and it won’t run under MySQL:

SELECT 
  id_manufacturer,
  id_partname,
  id_model,
  cnumber,
  COUNT (*)
FROM 
  rpi_consumables
GROUP BY 
  id_manufacturer, id_partname, id_model, cnumber
HAVING COUNT(*) > 1

Anyone have any ideas as to why the syntax fails?

Error Code: 1064 You have an error in your SQL syntax; check the
manual that corresponds to your MySQL server version for the right
syntax to use near ‘*) from rpi_consumables group by
id_manufacturer, id_partname, id_mode’ at line 6

Answer 1

There should be no space between COUNT and (*).

SELECT 
  id_manufacturer,
  id_partname,
  id_model,
  cnumber,
  COUNT(*) /* This is where the space needs to be removed */
FROM 
  rpi_consumables
GROUP BY 
  id_manufacturer, id_partname, id_model, cnumber
HAVING COUNT(*) > 1
