Spent way too long trying to get the --create-only flag to be picked up here.
Classic case of RTFM 🤦 - explainer in docs here why the additional -- is required https://www.prisma.io/docs/orm/more/development-environment/environment-variables/managing-env-files-and-setting-variables#using-dotenv-cli-via-command-line

| Run `npm run prisma:migrate` - this will apply to the change to your local dev database, and generate a migration file in `/prisma/migrations` | ||

| > The command `npm run prisma:migrate-create-only` will generate a migration file without running it. This is helpful if you want to add any additional changes, and manually configure the migration. For example when renaming a column Prisma may drop and recreate (thus losing data). Manually generating an `ALTER table UPDATE column` SQL command allows us to work around this. You'll then need to run `npm run prisma:migrate` to apply your changes. |

Maybe I'm being silly but I don't quite understand where "Manually generating an ALTER table UPDATE column SQL command" should be happening

Thanks - updated the docs now. Is this any clearer?
Keen to jump on a call and demo this so we're all confident making changes 🙂
What does this PR do?
--create-onlyflag - without this Prisma would drop and recreate the column. I needed to manually write the correct SQL in the migration file.
