### Search before asking - [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues. ### Description When use sqlalchemy with doris. There will be numbers wanging logs: ``` 2022-08-02 08:05:05,358 WARN (doris-mysql-nio-pool-65575|435146) [ConnectProcessor.handleQuery():226] Process one query failed because. org.apache.doris.common.AnalysisException: errCode = 2, detailMessage = Syntax error in line 1: ...collated returns' AS CHAR CHARACTER SET utf8mb4) COLLA... ^ Encountered: CHARACTER Expected: COMMA at org.apache.doris.qe.ConnectProcessor.analyze(ConnectProcessor.java:274) ~[palo-fe.jar:0.15-SNAPSHOT] at org.apache.doris.qe.ConnectProcessor.handleQuery(ConnectProcessor.java:200) ~[palo-fe.jar:0.15-SNAPSHOT] at org.apache.doris.qe.ConnectProcessor.dispatch(ConnectProcessor.java:349) ~[palo-fe.jar:0.15-SNAPSHOT] at org.apache.doris.qe.ConnectProcessor.processOnce(ConnectProcessor.java:538) ~[palo-fe.jar:0.15-SNAPSHOT] at org.apache.doris.mysql.nio.ReadListener.lambda$handleEvent$0(ReadListener.java:50) ~[palo-fe.jar:0.15-SNAPSHOT] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) [?:?] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) [?:?] at java.lang.Thread.run(Thread.java:829) [?:?] Caused by: org.apache.doris.common.AnalysisException: errCode = 2, detailMessage = Syntax error at org.apache.doris.analysis.SqlParser.unrecovered_syntax_error(SqlParser.java:2076) ~[palo-fe.jar:0.15-SNAPSHOT] at java_cup.runtime.lr_parser.parse(lr_parser.java:616) ~[jflex-1.4.3.jar:?] at org.apache.doris.common.util.SqlParserUtils.getMultiStmts(SqlParserUtils.java:59) ~[palo-fe.jar:0.15-SNAPSHOT] at org.apache.doris.qe.ConnectProcessor.analyze(ConnectProcessor.java:265) ~[palo-fe.jar:0.15-SNAPSHOT] ... 7 more ``` And It is valid for mysql. So it makes warning log to useless. ### Use case unicode test sql: ``` SELECT CAST('test collated returns' AS CHAR CHARACTER SET utf8) COLLATE utf8mb4_bin AS anon_1; ``` https://github.com/sqlalchemy/sqlalchemy/blob/1536bc4664a248faf81c62326fe1be3dbe18b8cd/lib/sqlalchemy/dialects/mysql/mysqldb.py#L90 ### Related issues _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
