unique_table()
table table which should be chaked
table_list list of tables
table table which should be chaked
table_list list of tables
NOTE: to exclude derived tables from check we use following mechanism:
a) during derived table processing set THD::derived_tables_processing
b) JOIN::prepare set SELECT::exclude_from_table_unique_test if
THD::derived_tables_processing set. (we can't use JOIN::execute
because for PS we perform only JOIN::prepare, but we can't set this
flag in JOIN::prepare if we are not sure that we are in derived table
processing loop, because multi-update call fix_fields() for some its
items (which mean JOIN::prepare for subqueries) before unique_table
call to detect which tables should be locked for write).
c) unique_table skip all tables which belong to SELECT with
SELECT::exclude_from_table_unique_test set.
Also SELECT::exclude_from_table_unique_test used to exclude from check
tables of main SELECT of multi-delete and multi-update
TODO: when we will have table/view change detection we can do this check
only once for PS/SP
