 Description   

EXPLAIN FORMAT=JSON doesn't show outer_ref_table cond.

This is a condition that is a part of subquery's WHERE condition that

  • depends on outer reference tables (and so this is not a "constant condition")
  • does not depend on any tables in the subquery

we produce and evaluate it but EXPLAIN FORMAT=JSON doesn't show it.
