class Book {
String title
Date releaseDate
String author
Boolean paperback
}findAllBy*
Purpose
Dynamic method that uses the properties of the domain class to create query method expressions that return all matching instances of the domain class
Examples
Given this domain class:
The following are all possible:
def results = Book.findAllByTitle("The Shining",
[max: 10, sort: "title", order: "desc", offset: 100])
results = Book.findAllByTitleAndAuthor("The Sum of All Fears", "Tom Clancy")
results = Book.findAllByReleaseDateBetween(firstDate, new Date())
results = Book.findAllByReleaseDateGreaterThanEquals(firstDate)
results = Book.findAllByTitleLike("%Hobbit%")
results = Book.findAllByTitleIlike("%Hobbit%") // ignore case
results = Book.findAllByTitleNotEqual("Harry Potter")
results = Book.findAllByReleaseDateIsNull()
results = Book.findAllByReleaseDateIsNotNull()
results = Book.findAllPaperbackByAuthor("Douglas Adams")
results = Book.findAllNotPaperbackByAuthor("Douglas Adams")
results = Book.findAllByAuthorInList(["Douglas Adams", "Hunter S. Thompson"])Description
GORM supports the notion of Dynamic Finders. The findAllBy* method finds all the results for the given method expression.
Parameters:
-
metaParams- AMapcontaining pagination parametersmax,order,offsetandsortand metaParametersreadOnly,timeout,fetchSize, andflushMode
Pagination and sorting parameters can be used as the last argument to a dynamic method:
def results = Book.findAllByTitle("The Shining",
[max: 10, sort: "title", order: "desc", offset: 100])If no items meet the supplied criteria an empty list is returned.
The following operator names can be used within the respective dynamic methods:
-
LessThan -
LessThanEquals -
GreaterThan -
GreaterThanEquals -
Between -
Like -
Ilike(i.e. ignorecase like) -
IsNotNull -
IsNull -
Not -
NotEqual -
And -
Or -
InList
These operator names can be considered keywords, and you will run into problems when querying domain classes that have one of these names as property names. For more information on dynamic finders refer to the user guide.
