…e is useless in some scene (apache#41472) This is brought by apache#34050 if set `enable_materialized_view_nest_rewrite = false`, as expected, top level materialized view should rewritten fail, but now successfully. Such as first level materialized view def is CREATE MATERIALIZED VIEW level1 BUILD IMMEDIATE REFRESH COMPLETE ON MANUAL DISTRIBUTED BY RANDOM BUCKETS 2 PROPERTIES ('replication_num' = '1') AS SELECT l_orderkey, l_linenumber, l_partkey, o_orderkey, o_custkey FROM lineitem_2 INNER JOIN orders_2 ON l_orderkey = o_orderkey; second level materialized view def is CREATE MATERIALIZED VIEW level2 BUILD IMMEDIATE REFRESH COMPLETE ON MANUAL DISTRIBUTED BY RANDOM BUCKETS 2 PROPERTIES ('replication_num' = '1') AS SELECT l_orderkey, l_linenumber, o_orderkey, sum(l_partkey) AS total_revenue, max(o_custkey) AS max_discount FROM join_mv1 GROUP BY l_orderkey, l_linenumber, o_orderkey; if set `enable_materialized_view_nest_rewrite = false`, only `level1` can rewriten succesfully and chosen by cbo if set `enable_materialized_view_nest_rewrite = true`, both `level1` and `level2` can rewriten succesfully and `level2` should be chosen by cbo. This pr fixed this
…ize view (apache#40106) In BI or some other SQL client，it will set `sql_select_limit` or `default_order_by_limit` session variables automatically. This will make mistake when query rewrite by materialized view, Because after query rewrite by materialized view, the rewritten plan would be optimized by rules again which should add limit on SQL. This pr fix this.
…e mv, data maybe wrong (apache#40173) When refresh partition mv, meanwhile, the query that can be written successfully by the same mv, if we run the query, the result maybe wrong. this pr fix this.
…pache#42206) This is brought by apache#32743 set enable_unicode_name_support = true; If run create view sql should fail beausel_shipdate column name contains invalid char '(' and ')', but now success this pr fix this and throw exception `ERROR 1105 (HY000): errCode = 2, detailMessage = Incorrect column name '(日期)'. Column regex is '^[_a-zA-Z@0-9\s/][.a-zA-Z0-9_+-/?@#$%^&*"\s,:]{0,255}$'` CREATE VIEW view1 AS SELECT "零售公司", l_shipdate as '(日期)', l_receiptdate as k2 FROM lineitem; and if run create view sql as following, should success: CREATE VIEW view2 AS SELECT "零售公司", l_shipdate as '日期', l_receiptdate as k2 FROM lineitem; and the schema of view2 should be mysql> desc view2; +-------------+-------------+------+-------+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------------+-------------+------+-------+---------+-------+ | __literal_0 | varchar(16) | No | false | NULL | | | 日期 | date | No | false | NULL | | | k2 | date | No | false | NULL | | +-------------+-------------+------+-------+---------+-------+ 3 rows in set (0.01 sec)
