Overview of String-Based Criteria API Queries
String-based Criteria API queries (“string-based queries”) are Java programming language queries that use
strings rather than strongly-typed metamodel objects to specify entity attributes when traversing a data
hierarchy. String-based queries are constructed similarly to metamodel queries, can be static or
dynamic, and can express the same kind of queries and operations as strongly-typed
metamodel queries.
Strongly-typed metamodel queries are the preferred method of constructing Criteria API queries. The
main advantage of string-based queries over metamodel queries is the ability to construct
Criteria queries at development time without the need to generate static metamodel classes
or otherwise access dynamically generated metamodel classes. The main disadvantage to string-based queries is
their lack of type safety, which may lead to runtime errors due
to type mismatches that would be caught at development time when using strongly-typed metamodel
queries.
For information on constructing criteria queries, see Chapter 35, Using the Criteria API to Create Queries.
