   <!-- 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.
