Question

I have this SQL query:

SELECT 
  *, 
  6371.04 * acos(cos(pi() / 2 - radians(90 - `Tournament`.`latitude`)) * cos(pi() / 2 - radians(90 - 37.226)) * cos(radians(`Tournament`.`longitude`) - radians(-93.4397)) + sin(pi() / 2 - radians(90 - `Tournament`.`latitude`)) * sin(pi() / 2 - radians(90 - 37.226))) AS `Tournament`.`dist` 
FROM `tournaments` AS `Tournament`   
WHERE 1 = 1   
ORDER BY `Tournament`.`dist` ASC  
LIMIT 5

I can’t figure out what could be possibly wrong with that statement. Here’s the error I’m getting:

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 '.`dist` FROM `tournaments` AS `Tournament`   WHERE 1 = 1   ORDER BY `Tournament`' at line 1

Could anyone point me in the right direction?

Answer 1

The keyword AS is supposed to be followed by an id, not a compound identifier.

From the manual:

A select_expr can be given an alias using AS alias_name. The alias is used as the expression’s column name and can be used in GROUP BY, ORDER BY, or HAVING clauses.
