Status: Closed |

| Problem description: |
A non-existent column is not detected if in a sub-query with a
valid where condition and the SELECT / UPDATE / DELETE considers
the WHERE clause as true
i.e.
table_a
acol1
acol2
acol3
table_b
bcol1
bcol2
A query like:
SELECT * FROM table_a WHERE acol3 = (SELECT bcol3 FROM table_b
WHERE bcol1 = 1);
If table_b does have a row that satisfies the WHERE clause bcol1
= 1 then the select on table_a gets all rows on table_a.
Same for an UPDATE and/or DELETE, might cause undesirable
results
It should error and report that there's a non-existent column |
