[Tarantool-patches] [PATCH v1 0/2] sql: fix comparison in IN operator

[imeevma@tarantool.org]

Prior to this patch-set, comparisons in the IN statement were
performed using SCALAR rules in most cases. This patch-set changes
this behavior for the case when the left value is not a vector
whose length is greater than one. Now the left value is searched
among the right values ​​only if they are comparable. If there is a
value that is not comparable with the left value, the operation
throws an error.

#ChangeLog
 - The IN operator now always throws an error if there is a value
   on the right that is not comparable with the left value (gh-4256).

Mergen Imeev (2):
  sql: fix comparison in IN with list of values
