Bug#46615 Assertion in Query_cache::invalidate in INSERT in a VIEW of a MERGE table

Browse Source 
If the listed columns in the view definition of 
the table used in a 'INSERT .. SELECT ..'
statement mismatched, a debug assertion would
trigger in the cache invalidation code
following the failing statement.

Although the find_field_in_view() function
correctly generated ER_BAD_FIELD_ERROR during
setup_fields(), the error failed to propagate
further than handle_select(). This patch fixes
the issue by adding a check for the return
value.


mysql-test/r/query_cache_with_views.result:
  * added test for bug 46615
mysql-test/t/query_cache_with_views.test:
  * added test for bug 46615
sql/sql_parse.cc:
  * added check for handle_select() return code before attempting to invalidate the cache.
