   Hi @iamhucong, all SQL cases listed in this issue are already supported on 
the current master, so I think we can close it as completed.
   
   - The `ALTER TABLE ... RENAME` family (`RENAME new_table_name`, `RENAME 
ROLLUP a b`, `RENAME PARTITION a b`, `RENAME COLUMN a b`, and `ALTER TABLE 
table1 RENAME table2`) was implemented in #37537, including the grammar rules, 
visitor segments, and assertion cases (`alter_table_rename_table_doris`, 
`alter_table_rename_column_doris`, `alter_table_rename_rollup`, 
`alter_table_rename_partition` in `sql/supported/ddl/alter-table.xml`).
   - `UCASE` is covered by the existing case `select_ucase` (`SELECT 
UCASE('hello')`, db-types `MySQL,Doris`), which @Rahulyadav4 also verified 
locally.
   - `ORTHOGONAL_BITMAP_EXPR_CALCULATE_COUNT` parses through the generic 
function-call rule, since the Doris grammar accepts any qualified identifier as 
a function name; sibling bitmap-function cases such as `BITMAP_OR_COUNT` 
already exist, and I verified the exact SQL from the docs parses successfully 
on master.
   
   I re-checked every remaining unchecked case on master and all of them parse 
without code changes, so there is nothing left to implement here. Thanks 
@Rahulyadav4 for the verification. I'll close this issue as completed; feel 
free to reopen if any listed SQL still fails on the latest master.
