Category of Error codes

1. What is the link to the documentation section that needs improving?
   Errors

2. Describe the confusion
   I'm currently building an API that uses node-oracledb. In my app, I'd like to know whether the error is caused by the data (ex: ORA-12899: value too large for column) or by a connectivity issue during runtime. I know there's a lot of error codes available, I found the documentation: https://docs.oracle.com/en/database/oracle/oracle-database/12.2/errmg/index.html

However, I can't find any documentation that tells which range of codes covers what type of error. Do I need to filter through the long list of error codes to identify which ones are for data error and connectivity error, or is there existing documentation or tool to achieve this?

3. Suggest changes that would help
   It would be great if the documentation categorizes error codes or an additional field in the Error object that will identify the type of error.

Start with the Errors section linked in the issue and compare it with Oracle's error message documentation. Determine whether the requested outcome is categorized documentation or a new Error object field, then define the data and connectivity categories and update the relevant documentation or API specification. Done means the requested error classification is documented and consistently understandable.
