(Quick Reference)
dynamicInsert
Purpose
Whether to dynamically build
INSERT queries
Examples
class Book { …
static mapping = {
dynamicInsert true
}
}Description
Usage:
dynamicInsert(boolean)By default Hibernate generates all queries at startup and caches them. This helps performance since insert, update, and delete queries don't have to be dynamically generated at runtime. However, there are certain circumstances where dynamic queries are useful.
For example if you were using custom
UserType to hash passwords, every time an UPDATE occurred, the password would get re-hashed. The
dynamicInsert method lets you turn off the dynamic creation of queries that uses only the properties that are needed to perform the insert.
