1. See [Wiki - how to post code on this forum](https://forum.inductiveautomation.com/t/wiki-how-to-post-code-on-this-forum/77831).
2. Don't create query strings using CONCAT(). You are leaving your system open to SQL injection attack. Ideally you would use [system.db.runNamedQuery | Ignition User Manual](https://docs.inductiveautomation.com/docs/8.1/appendix/scripting-functions/system-db/system-db-runNamedQuery) or [system.db.runPrepQuery | Ignition User Manual](https://docs.inductiveautomation.com/docs/8.1/appendix/scripting-functions/system-db/system-db-runPrepQuery).
