Any SQL that passes validation through `valreq` will definitely be deployable in a real cluster.

 ### CLI Framework
 
 We use `cliche` for the CLI interface. See [Manual](https://code.google.com/archive/p/cliche/wikis/Manual.wiki) and [source](https://github.com/budhash/cliche).
+
+Due to the simplicity of the framework, when quotation marks are required in the SQL, only single quotation marks can be used, and the entire SQL must be enclosed in double quotation marks. Otherwise, the parsing will discard the double quotation marks in the SQL.
+
+### Debugging
+
+If you encounter any issues during usage, you can specify `log4j.properties` using `-Dlog4j.configuration=`. By default, the log level is set to WARN, but you can change it to print INFO and above logs to obtain more runtime information.
+
+To test in the project:
+```bash
+java -jar target/emulator-1.1-SNAPSHOT.jar -Dlog4j.configuration=./src/test/resources/log4j.properties
+```

 你可以使用`val`和`valreq`分别进行在线批模式和在线请求模式（即服务部署上线）的OpenMLDB SQL验证。例如，我们测试一个SQL是否能被`DEPLOY`上线，使用`valreq`命令：
 
 ```sql
-# table creations - t/addtable: create table
+# table 创建 - t/addtable: create table
 addtable t1 a int, b int64
+addtable t2 a int, b string
 
-# validate in online request mode

+# SQL中存在单引号时（目前不支持双引号，只能使用单引号），请用双引号括起来，避免解析遗漏引号
+valreq "select * from t1 join t2 on t2.b='abc'"
 ```
 
 如果测试不通过，将打印SQL编译错误；通过则打印`validate * success`。整个过程在虚拟环境中，无需担心建表后的资源占用，也没有任何副作用。只要`valreq`验证通过的 SQL，则一定能在真实集群中上线。

 ### CLI框架
 
 我们使用`cliche`作为CLI框架，详见[操作手册](https://code.google.com/archive/p/cliche/wikis/Manual.wiki) 和[source](https://github.com/budhash/cliche)。
+
+由于框架简单，SQL中必须存在引号时，只能使用单引号，并将整个SQL用双引号括起来。否则，解析会丢掉SQL中的双引号。
+
+### 调试
+
+使用过程中如果出现问题，可以通过`-Dlog4j.configuration=`指定`log4j.properties`，默认是WARN日志，可以改为打印INFO及以上的日志，能获取更多运行信息。
+
+在项目中测试：
+```bash
+java -jar target/emulator-1.1-SNAPSHOT.jar -Dlog4j.configuration=./src/test/resources/log4j.properties
