[hibernate-dev] 6.0 - formalized standard functions

Hibernate has always defined a set of functions that should always be available on every Dialect/database. JPA formalized some of these, but Hibernate still had a superset. So I wanted to formalize the complete set of supported functions. Here is the formalized list of what Hibernate has always considered the "supported list": - those defined by JPA - abs - avg - concat - count - current_date - current_time - current_timestamp - length - locate - lower - max - min - mod - sqrt - substring - sum - trim - upper - Hibernate extensions - bit_length - coalesce - not technically a function, but supported as such to allow overriding - cast - day - generally defined as `extract(day from ?1)` - extract - hour - generally defined as `extract(hour from ?1)` - minute - generally defined as `extract(minute from ?1)` - month - generally defined as `extract(month from ?1)` - nullif - not technically a function, but supported as such to allow overriding - second - generally defined as `extract(second from ?1)` - str - generally defined as `cast(?1 as CHAR )` - year - generally defined as `extract(year from ?1)` Additions/subtractions anyone would like to discuss? One question I has was in regards to str being defined as `cast(?1 as CHAR )` by default - specifically using CHAR instead of VARCHAR. Some databases apply padding for the size of the datatype when casting a numeric to a CHAR which is not an unreasonable thing to do.
