### Dify version

v1.17.0

### Cloud or Self Hosted

Self Hosted (Docker)

### Steps to reproduce

The junjiem/db_query plugin fails to connect to Oracle 11g databases. The underlying python-oracledb driver defaults to "Thin mode," which does not support older Oracle server versions (like 11g), resulting in a DPY-3010 error.

### ✔️ Expected Behavior

I expect the plugin to successfully connect to Oracle 11g databases without throwing a DPY-3010 error.
Specifically, the plugin should support the "Thick mode" of python-oracledb (by calling oracledb.init_oracle_client()), or provide a configuration option to enable it. This is necessary because Oracle 11g is not supported in the default "Thin mode"

### ❌ Actual Behavior

_No response_

Start by locating the junjiem/db_query plugin and its python-oracledb connection setup, then reproduce the DPY-3010 failure against an Oracle 11g database. Check how oracledb.init_oracle_client() or a configuration option could be supported; done means the plugin connects successfully to Oracle 11g without the error.
