Low-Level Database Query Tool

The Low-Level Database Query Tool is an advanced debugging feature of the Hornbill Platform which allows you to query the underlying application database using Structured Query Language (SQL) statements. Every Hornbill instance incorporates this feature however it is not enabled by default and its use is not encouraged. This feature is intended for advanced users only to support diagnostics of issues and problems.

Warning

This function of the Hornbill platform is disabled and protected behind a super-user privilege level because it exposes some inherent security risks with regards to accessing data a user may not be authorized to access. As a result this feature is likely to be depreciated in the future. The platform, and our cloud operations and support capabilities have matured beyond the point where this is beneficial, there are no use-0cases where its really necessary to access the underlying database in this way.

Enabling the Low-Level Database Query Tool

The visibility of Low-Level Database Query Tool is governed by a system setting security.database.allowSqlQueryOperation. Any user wishing to use the Low-Level Database Query Tool must be assigned the “Super User Role”.

Once the application setting has been enabled, it may be necessary to refresh your browser to allow this change in this setting to be acknowledged. If the association of a role is also required, it will be necessary for the user to log out and then log in again to ensure the user’s session is aware of the recent association of the Super User role.
