In my Lucee 4.5 application I was using multiple datasources in ORM, both MSSQL and MySQL.
In Lucee 5.2 I have to specify a dialect in ORM settings, which prevents me from using both MySQL and MSSQL in one application. It is not possible to specify multiple dialects.
Lucee 220.127.116.11 support struct and simple values for dialect,dbcreate,schema,sqlscript and catalog.
improving autodetecting dialect wit hibernate 3 will take a lot of this, most likely a fix not necessary when we move to Hibernate 5. So we will not address that issue for the moment.
We prefer to spend that tiume migrating to Hibernate 5.
