<!-- Greeting --> @MuLeiSY2021 你好! 我是[Dosu](https://dosu.dev),一个可以帮助你解决 bug、回答问题并成为贡献者的机器人。在等待人类维护者的过程中,我可以帮助你。 <!-- Answer --> The error you're encountering is related to a SQL syntax issue when querying the MySQL database. The specific error message indicates a problem with the SQL syntax near `[pos=0 lim=9 cap=9])`. This suggests that there might be an issue with how the query is being constructed or executed in the `MysqlTable.query` method. Here are a few steps you can take to address this issue: 1. **Update MySQL Driver**: The log mentions that the `com.mysql.jdbc.Driver` is deprecated. Ensure that you are using the correct driver class `com.mysql.cj.jdbc.Driver` for MySQL Connector/J 8.0.28. Update your configuration to use this driver if it hasn't been done already <sup>[[1]](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-server/hugegraph-mysql/src/main/java/org/apache/hugegraph/backend/store/mysql/MysqlOptions.java)</sup>. 2. **Check SQL Query Construction**: Review the `MysqlTable.query` method to ensure that the SQL query is being constructed correctly. The error might be due to incorrect handling of query parameters or conditions. This method is responsible for converting a `Query` object into SQL statements, and any misconfiguration could lead to syntax errors <sup>[[2]](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-server/hugegraph-mysql/src/main/java/org/apache/hugegraph/backend/store/mysql/MysqlTable.java)</sup>. 3. **Verify Database Schema**: Ensure that the database schema matches the expected structure. Any discrepancies in table names, column names, or data types could lead to syntax errors during query execution. 4. **Review Configuration Files**: Double-check your `rest-server.properties` and any other configuration files to ensure that all settings are correct and consistent with your MySQL setup <sup>[[3]](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-server/hugegraph-dist/src/assembly/static/conf/rest-server.properties)</sup>. By addressing these areas, you should be able to resolve the SQL syntax error and get the HugeGraph server running correctly. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* --- <sup>Help Dosu learn!
