DESCRIPTION
Copy ref key and check for null parts in it.
Depending on the nullability and conversion problems this function
recognizes and processes the following states :
1. Partial match on top level. This means IN has a value of FALSE
regardless of the data in the subquery table.
Detected by finding a NULL in the left IN operand of a top level
expression.
We may actually skip reading the subquery, so return TRUE to skip
the table scan in subselect_uniquesubquery_engine::exec and make
the value of the IN predicate a NULL (that is equal to FALSE on
top level).
2. No exact match when IN is nested inside another predicate.
Detected by finding a NULL in the left IN operand when IN is not
a top level predicate.
We cannot have an exact match. But we must proceed further with a
table scan to find out if it's a partial match (and IN has a value
of NULL) or no match (and IN has a value of FALSE).
So we return FALSE to continue with the scan and see if there are
any record that would constitute a partial match (as we cannot
determine that from the index).
3. Error converting the left IN operand to the column type of the
right IN operand. This counts as no match (and IN has the value of
FALSE). We mark the subquery table cursor as having no more rows
(to ensure that the processing that follows will not find a match)
and return FALSE, so IN is not treated as returning NULL.
RETURN
FALSE - ok, index lookup key without keys copied.
TRUE - an error occured while copying the key
FALSE - The value of the IN predicate is not known. Proceed to find the
value of the IN predicate using the determined values of
null_keypart and table->status.
TRUE - IN predicate has a value of NULL. Stop the processing right there
and return NULL to the outer predicates.

Merge ON expressions for a view
SYNOPSIS
merge_on_conds()
thd thread handle

is_cascaded TRUE <=> merge ON expressions from underlying views
DESCRIPTION
This function returns the result of ANDing the ON expressions
of the given view and all underlying views. The ON expressions
of the underlying views are added only if is_cascaded is TRUE.
RETURN
Pointer to the built expression if there is any.
Otherwise and in the case of a failure NULL is returned.
