dynamicUpdate
Purpose
Whether to dynamically build UPDATE
queries
Examples
Description
Usage: dynamicUpdate(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 dynamicUpdate
method lets you turn off the dynamic creation of queries that uses only the properties that are needed to perform the update.
