Question

i have this simple SQL join query, which is giving me a syntax error on the second FROM

SELECT * FROM ##temporderstable P 
FROM supporder Y join backorder ON P.catalogid = Y.backorder 
GROUP BY P.catalogid

i can’t figure out whats wrong with it, any hints?

Thanks in advance

Answer 1

You can’t have two FROM clauses like that…

You might mean JOIN but you’d need another ON condition:

SELECT *
  FROM ##temporderstable P 
  JOIN supporder Y ON P.catalogid = Y.backorder 
  JOIN backorder B ON B.xxxxxxxxx = P.xxxxyyyyy
 GROUP BY P.catalogid;

The second ON would need to reference a column of B and a column of either P or Y.
