This query works in MySQL Workbench.

INSERT INTO manf_dashboard.production_log 
			(machineId, event, cycleCount, goodCount, sku, runstatus) 
			VALUES ('Delete', 'test', 44, 33, 'Dummy', 0)

It fails in Designer Script Console

query = """INSERT INTO manf_dashboard.production_log 
			(machineId, event, cycleCount, goodCount, sku, runstatus) 
			VALUES ('Delete', 'test', 44, 33, 'Dummy', 0)"""
system.db.runPrepUpdate(query, [])

I've checked the database connection using the select query below and it works.

system.db.runQuery("SELECT * FROM manf_dashboard.production_log LIMIT 10")

Can anyone suggest some further checks for me to narrow down the cause of the problem?

Many thanks.

Set your designer to read/write mode. (Yes, the same setting for tags impacts legacy DB script functions.)
