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

Method Detail

addSynchronizedQuerySpace

SQLQuery addSynchronizedQuerySpace(java.lang.String querySpace)

Adds a query space (table name) for (a) auto-flush checking and (b) query result cache invalidation checking

Parameters:

querySpace - The query space to be auto-flushed for this query.

Returns:

this, for method chaining

addSynchronizedEntityName

SQLQuery addSynchronizedEntityName(java.lang.String entityName)
                                   throws MappingException

Adds an entity name for (a) auto-flush checking and (b) query result cache invalidation checking. Same as addSynchronizedQuerySpace(java.lang.String) for all tables associated with the given entity.

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

addSynchronizedEntityClass

SQLQuery addSynchronizedEntityClass(java.lang.Class entityClass)
                                    throws MappingException

Adds an entity for (a) auto-flush checking and (b) query result cache invalidation checking. Same as addSynchronizedQuerySpace(java.lang.String) for all tables associated with the given entity.

Parameters:

entityClass - The class of the entity upon whose defined query spaces we should additionally synchronize.

Returns:

this, for method chaining

Throws:

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

setResultSetMapping

SQLQuery setResultSetMapping(java.lang.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(java.lang.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

addScalar

SQLQuery addScalar(java.lang.String columnAlias,
                 Type type)

Declare a scalar query result.

type - The Hibernate type as which to treat the value.

Returns:

this, for method chaining
