By default, Hibernate creates SQL statements for each persistent class on startup. These statements are simple create, read, update, and delete operations for reading a single row, deleting a row, and so on. How can Hibernate create an UPDATE statement on startup After all, the columns to be updated aren t known at this time. The answer is that the generated SQL statement updates all columns, and if the value of a particular column isn t modified, the statement sets it to its old value. In some situations, such as a legacy table with hundreds of columns where the SQL statements will be large for even the simplest operations (say, only one column needs updating), you have to turn off this startup SQL generation and switch to dynamic statements generated at runtime. An extremely large number of entities can also impact startup time, because Hibernate has to generate all SQL statements for CRUD upfront. Memory consumption for this query statement cache will also be high if a dozen statements must be cached for thousands of entities (this isn t an issue, usually). Two attributes for disabling CRUD SQL generation on startup are available on the <class> mapping element:
