Hi all, quick question, I've noticed that Date is mapped to datetime in MySQL which doesn't store the fractional seconds (SS.sss), thought the type has a length that allows to store up to 6 digits e.g. datetime(3) stores 3 fractional seconds. Is there a DSL to set the length of the datetime? Thanks!

Have you tried adjusting the type in mapping? https://docs.grails.org/snapshot/grails-data/hibernate5/manual/index.html

I couldn't find an example that maps to a specific type like datetime(3)

"DATETIME(3)" should do it. You will need to regenerate and rerun the migration.

you mean with sqlType: "DATETIME(3)"?
