Interface SQLQuery

All Superinterfaces:
  Query

All Known Implementing Classes:
  SQLQueryImpl

    public interface SQLQuery

extends Query

Represents a "native sql" query and allows the user to define certain aspects about its execution, such as:

- result-set value mapping (see below)
- Tables used via `addSynchronizedQuerySpace(java.lang.String)`, `addSynchronizedEntityName(java.lang.String)` and `addSynchronizedEntityClass(java.lang.Class)`. This allows Hibernate to properly know how to deal with auto-flush checking as well as cached query results if the results of the query are being cached.

In terms of result-set mapping, there are 3 approaches to defining:

- If this represents a named sql query, the mapping could be associated with the query as part of its metadata
- A pre-defined (defined in metadata and named) mapping can be associated with `setResultSetMapping(java.lang.String)`
- Defined locally per the various `addEntity(java.lang.String)`, `addRoot(java.lang.String, java.lang.String)`, `addJoin(java.lang.String, java.lang.String)`, `addFetch(java.lang.String, java.lang.String, java.lang.String)` and `addScalar(java.lang.String)` methods

  Parameters:
    `entityName` - The name of the entity upon whose defined query spaces we should additionally synchronize.
  Returns:
    this, for method chaining
  Throws:
    `MappingException` - Indicates the given name could not be resolved as an entity

  Throws:
    `MappingException` - Indicates the given class could not be resolved as an entity

### setResultSetMapping

    SQLQuery setResultSetMapping(String name)

  Use a predefined named result-set mapping. This might be defined by a `<result-set/>` element in a Hibernate `hbm.xml` file or through a `SqlResultSetMapping` annotation.

  Parameters:
    `name` - The name of the mapping to use.
  Returns:
    this, for method chaining

### addScalar

    SQLQuery addScalar(String columnAlias)

  Declare a scalar query result. Hibernate will attempt to automatically detect the underlying type.

  Functions like `<return-scalar/>` in `hbm.xml` or `ColumnResult`

  Parameters:
    `columnAlias` - The column alias in the result-set to be processed as a scalar result
  Returns:
    `this`, for method chaining

  Parameters:
    `columnAlias` - The column alias in the result-set to be processed as a scalar result
