The following methods alters the behavior of the executed query, some can be a life saver, so check them all out.
You can also tell Hibernate to transform the results to other formats for you once you retrieve them.
asDistinct()
- Applies a result transformer of DISTINCT_ROOT_ENTITY
asStruct()
- Applies a result transformer of ALIAS_TO_ENTITY_MAP so you get an array of structs instead of array of objects
asStream()
- Get the results as a CBstream
Method
Description
cache(boolean cache=true, cacheRegion)
Tells Hibernate whether to cache the query or not (if the query cache is enabled), and optionally choose a cache region
cacheRegion(cacheRegion)
Tells Hibernate the cache region to store the query under
comment(comment)
Add a comment to the generated SQL.
fetchSize(numeric fetchSize)
Set's the fetch size of the underlying JDBC query
firstResult(numeric firstResult)
Specifies the offset for the results. A value of 0 will return all records up to the maximum specified.
maxResults(numeric maxResults)
Set a limit upon the number of objects to be retrieved.
order(property,sortDir='asc',ignoreCase=false)
Specifies both the sort property (the first argument, the sort order (either 'asc' or 'desc'), and if it should ignore cases or not
peek( target )
Peek into the criteria build process with your own closure that accepts the criteria itself.
queryHint(hint)
Add a DB query hint to the SQL. These differ from JPA's QueryHint, which is specific to the JPA implementation and ignores DB vendor-specific hints. Instead, these are intended solely for the vendor-specific hints, such as Oracle's optimizers. Multiple query hints are supported; the Dialect will determine concatenation and placement.
readOnly(boolean readOnly)
Set the read-only/modifiable mode for entities and proxies loaded by this Criteria, defaults to readOnly=true
timeout(numeric timeout)
Set a timeout for the underlying JDBC query in milliseconds.
when( test, target )
A nice functional method to allow you to pass a boolean evaulation and if true, the target closure will be executed for you, which will pass in the criteria object to it.
