Oracle DELETE sql with JOIN doesn't work

Question

My delete statement returns a 933 error in Oracle, I\'m not sure what is wrong-

DELETE b
from temp a
JOIN
  fact_tab b
on a.col1 = b.col1
and a.col2 = b.col2
and         


        

Answer 1

Oracle doesn't allow JOIN in a DELETE statement directly like that.

You could do the delete in the following way:

DELETE
FROM fact_tab
WHERE ROWID IN
  (SELECT b.rowid
  FROM temp a
  JOIN fact_tab b
  ON a.col1  = b.col1
  AND A.col2 = b.col2
  AND A.col3 = b.col3
  );

You could also use WHERE EXISTS clause.
