### Search before asking - [x] I had searched in the [issues](https://github.com/apache/doris/issues) and found no similar issues. ### Version Reproduced with the table stream regression case on local Doris HEAD `d4a077caf8a`. Test environment: ```text regression-test/suites/table_stream_p0/test_table_stream_cancel_alter.groovy remote log: /mnt/disk1/jianxu/case_output/doris/testrun/table_stream_p0_20260708/test_table_stream_cancel_alter.final.log FE: 172.20.49.4:9030 ``` ### What's Wrong? `CANCEL ALTER STREAM` is not accepted by the SQL parser. The parser currently expects `TABLE` after `CANCEL ALTER`, so the statement fails before it can reach table stream alter-cancel handling. Failing SQL: ```sql CANCEL ALTER STREAM s_cancel; ``` Actual error: ```text errCode = 2, detailMessage = mismatched input 'STREAM' expecting 'TABLE'(line 1, pos 13) ``` ### What You Expected? `CANCEL ALTER STREAM s_cancel` should be parsed as a table stream statement. If there is no in-progress alter stream job, it should return a clear semantic error, for example: ```text no alter stream job ``` ### How to Reproduce? Regression case: ```text regression-test/suites/table_stream_p0/test_table_stream_cancel_alter.groovy ``` Minimal flow: ```sql CREATE TABLE base_cancel ( k1 INT, v1 INT ) DUPLICATE KEY(k1) DISTRIBUTED BY HASH(k1) BUCKETS 1 PROPERTIES ( "replication_num" = "1", "binlog.enable" = "true", "binlog.format" = "ROW" ); CREATE STREAM s_cancel ON TABLE base_cancel PROPERTIES ("type" = "append_only"); CANCEL ALTER STREAM s_cancel; ``` ### Regression Test Result ```text suite: test_table_stream_cancel_alter command: CANCEL ALTER STREAM s_cancel expected: exception message contains "no alter stream job" actual: mismatched input 'STREAM' expecting 'TABLE'(line 1, pos 13) ``` ### Anything Else?
