### 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. ### Version 1.1.1-rc03 ### What's Wrong? My DB name is `default`, which is also an SQL keyword, but it shouldn't be a problem since I can easily escape it with a grave accent when writing SQL statements on my own. However, the SQL statements generated by FE sometimes forget to escape it, leaving a message like ``` Failed to execute sql: org.apache.doris.common.AnalysisException: errCode = 2, detailMessage = Syntax error in line 1: SELECT * FROM default.TABLE_NAME LIMIT 10 ^ Encountered: DEFAULT Expected: DEFAULT is keyword, maybe `DEFAULT` ``` since the keyword `DEFAULT` is not escaped, the SQL statement was a syntax error. ### What You Expected? All keywords in the SQL queries be correctly escaped. ### How to Reproduce? 1. Install Doris and run the BE and FE, and register the BE to the FE, namely following the instruction on https://doris.apache.org/zh-CN/docs/get-starting/ 2. Create a database named `default` with SQL statement `CREATE DATABASE `default``. 3. Create a table named `TABLE_NAME` into the DB just created 4. Enter the FE, click Playground, choose `default_cluster:default` on the left, then choose `TABLE_NAME` to select the table. Then click "Data preview" on the right panel. Instead of showing sample data, the user sees a pop-up error: ``` Failed to execute sql: org.apache.doris.common.AnalysisException: errCode = 2, detailMessage = Syntax error in line 1: SELECT * FROM default.TABLE_NAME LIMIT 10 ^ Encountered: DEFAULT Expected: DEFAULT is keyword, maybe `DEFAULT` ``` ### Anything Else? _No response_ ### Are you willing to submit PR? - [X] 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.
