Function 1:
check the select query plan is contain the stmt as following or not
SELECT
[hint_statement, ...]
[ALL | DISTINCT | DISTINCTROW | ALL EXCEPT ( col_name1 [, col_name2, col_name3, ...] )]
elect_expr [, select_expr ...]
[FROM table_references
PARTITION partition_list]
[TABLET tabletid_list]
[TABLESAMPLE sample_value [ROWS | PERCENT]
[REPEATABLE pos_seek]]
[WHERE where_condition]
[GROUP BY [GROUPING SETS | ROLLUP | CUBE] {col_name | expr | position}]
[HAVING where_condition]
[ORDER BY {col_name | expr | position}
[ASC | DESC], ...]
[LIMIT {[offset,] row_count | row_count OFFSET offset}]
[INTO OUTFILE 'file_name']
if analyzedPlan contains the stmt as following
[PARTITION partition_list]
[TABLET tabletid_list] or
[TABLESAMPLE sample_value [ROWS | PERCENT]
[REPEATABLE pos_seek]]
this method will return true.
Function 2:
Get related base table info which materialized view plan column reference,
input param plan should be rewritten plan that sub query should be eliminated
