# Proposed changes Issue Number: close #9740 ## Problem Summary: Current, we process `order by` and `limit` in Doris only way: https://github.com/apache/incubator-doris/blob/d97e2b1eb21b1026ef95f0cb5b87e0138c704de8/fe/fe-core/src/main/cup/sql_parser.cup#L3174-L3191 I think we need to change it behavior to standard SQL. query organization need to be executed at last. change syntax to match standard sql: ``` query = ctes? set_operand_list order_by limit set_operand_list = set_operand | set_operand_list set_op set_operand set_operand = selectClause fromClause? whereClause? aggregationClause? havingClause? | values | LEFT_PAREN query RIGHT_PAREN ``` ## Checklist(Required) 1.
