接口 Query<R>

    • 方法详细资料

      • getQueryString

        String getQueryString()
        已过时。
        Get the query string.
        返回:
        the query string

      • getQueryOptions

        RowSelection getQueryOptions()
        已过时。
        "QueryOptions" is a better name, I think, than "RowSelection" -> 6.0
        返回:
        Return the encapsulation of this query's options, which includes access to firstRow, maxRows, timeout and fetchSize. Important because this gives access to those values in their Integer form rather than the primitive form (int) required by JPA.

      • setHibernateFirstResult

        @Deprecated
default Query setHibernateFirstResult​(int firstRow)
        已过时。
        setFirstResult(int) should be used instead.
        Set the position of the first query result to be retrieved. A negative value will result in pagination starting from position 0.
        参数:
        firstRow - - the position of the first query result
        返回:
        this, for method chaining

      • setHibernateMaxResults

        @Deprecated
default Query setHibernateMaxResults​(int maxResults)
        已过时。
        setMaxResults(int) should be used instead.
        Set the maximum number of query results to be retrieved. A value less than or equal to 0 is considered uninitialized, resulting in no limit on the number of results.
        参数:
        maxResults - - the maximum number of query results
        返回:
        this, for method chaining

      • getHibernateFlushMode

        FlushMode getHibernateFlushMode()
        已过时。
        Obtain the FlushMode in effect for this query. By default, the query inherits the FlushMode of the Session from which it originates.
        指定者:
        getHibernateFlushMode 在接口中 BasicQueryContract<R>
        返回:
        The query FlushMode.
        另请参阅:
        FlushMode

      • getFlushMode

        javax.persistence.FlushModeType getFlushMode()
        已过时。
        For users of the Hibernate native APIs, we've had to rename this method as defined by Hibernate historically because the JPA contract defines a method of the same name, but returning the JPA FlushModeType rather than Hibernate's FlushMode. For the former behavior, use Query.getHibernateFlushMode() instead.
        指定者:
        getFlushMode 在接口中 javax.persistence.Query
        返回:
        The FlushModeType in effect for this query.

      • getCacheMode

        CacheMode getCacheMode()
        已过时。
        Obtain the CacheMode in effect for this query. By default, the query inherits the CacheMode of the Session from which is originates. NOTE: The CacheMode here only effects reading/writing of the query cache, not the entity/collection caches.
        指定者:
        getCacheMode 在接口中 BasicQueryContract<R>
        返回:
        The query CacheMode.
        另请参阅:
        Session.getCacheMode(), CacheMode

      • setCacheMode

        Query<R> setCacheMode​(CacheMode cacheMode)
        已过时。
        (Re)set the current CacheMode in effect for this query.
        指定者:
        setCacheMode 在接口中 BasicQueryContract<R>
        参数:
        cacheMode - The new CacheMode to use.
        返回:
        this, for method chaining
        另请参阅:
        getCacheMode()

      • isCacheable

        boolean isCacheable()
        已过时。
        Are the results of this query eligible for second level query caching? This is different than second level caching of any returned entities and collections. NOTE: the query being "eligible" for caching does not necessarily mean its results will be cached. Second level query caching still has to be enabled on the SessionFactory for this to happen. Usually that is controlled by the hibernate.cache.use_query_cache configuration setting.
        指定者:
        isCacheable 在接口中 BasicQueryContract<R>
        返回:
        true if the query results are eligible for caching, false otherwise.
        另请参阅:
        AvailableSettings.USE_QUERY_CACHE

      • setCacheable

        Query<R> setCacheable​(boolean cacheable)
        已过时。
        Enable/disable second level query (result) caching for this query.
        指定者:
        setCacheable 在接口中 BasicQueryContract<R>
        参数:
        cacheable - Should the query results be cacheable?
        返回:
        this, for method chaining
        另请参阅:
        isCacheable()

      • getCacheRegion

        String getCacheRegion()
        已过时。
        Obtain the name of the second level query cache region in which query results will be stored (if they are cached, see the discussion on isCacheable() for more information). null indicates that the default region should be used.
        指定者:
        getCacheRegion 在接口中 BasicQueryContract<R>
        返回:
        The specified cache region name into which query results should be placed; null indicates the default region.

      • setCacheRegion

        Query<R> setCacheRegion​(String cacheRegion)
        已过时。
        Set the name of the cache region where query results should be cached (if cached at all).
        指定者:
        setCacheRegion 在接口中 BasicQueryContract<R>
        参数:
        cacheRegion - the name of a query cache region, or null to indicate that the default region should be used.
        返回:
        this, for method chaining
        另请参阅:
        getCacheRegion()

      • setTimeout

        Query<R> setTimeout​(int timeout)
        已过时。
        Set the query timeout in seconds. NOTE it is important to understand that any value set here is eventually passed directly through to the JDBC Statement which expressly disallows negative values. So negative values should be avoided as a general rule.
        指定者:
        setTimeout 在接口中 BasicQueryContract<R>
        参数:
        timeout - the timeout in seconds
        返回:
        this, for method chaining
        另请参阅:
        getTimeout()

      • getFetchSize

        Integer getFetchSize()
        已过时。
        Obtain the JDBC fetch size hint in effect for this query. This value is eventually passed along to the JDBC query via Statement.setFetchSize(int). As defined b y JDBC, this value is a hint to the driver to indicate how many rows to fetch from the database when more rows are needed. NOTE : JDBC expressly defines this value as a hint. It may or may not have any effect on the actual query execution and ResultSet processing depending on the driver.
        指定者:
        getFetchSize 在接口中 BasicQueryContract<R>
        返回:
        The timeout in seconds
        另请参阅:
        Statement.getFetchSize(), Statement.setFetchSize(int)

      • setFetchSize

        已过时。
        Sets a JDBC fetch size hint for the query.
        指定者:
        setFetchSize 在接口中 BasicQueryContract<R>
        参数:
        fetchSize - the fetch size hint
        返回:
        this, for method chaining
        另请参阅:
        getFetchSize()

      • getReturnTypes

        @Deprecated
Type[] getReturnTypes()
        已过时。
        (since 5.2) with no replacement; to be removed in 6.0
        Return the Hibernate types of the query results.
        指定者:
        getReturnTypes 在接口中 BasicQueryContract<R>
        返回:
        an array of types

      • getLockOptions

        LockOptions getLockOptions()
        已过时。
        Obtains the LockOptions in effect for this query.

      • setLockMode

        Query<R> setLockMode​(String alias,
                     LockMode lockMode)
        已过时。
        Set the LockMode to use for specific alias (as defined in the query's FROM clause). The alias-specific lock modes specified here are added to the query's internal LockOptions. The effect of these alias-specific LockModes is somewhat dependent on the driver/database in use. Generally speaking, for maximum portability, this method should only be used to mark that the rows corresponding to the given alias should be included in pessimistic locking (LockMode.PESSIMISTIC_WRITE).
        参数:
        alias - a query alias, or "this" for a collection filter
        lockMode - The lock mode to apply.
        返回:
        this, for method chaining
        另请参阅:
        getLockOptions()

      • getComment

        String getComment()
        已过时。
        Obtain the comment currently associated with this query. Provided SQL commenting is enabled (generally by enabling the hibernate.use_sql_comments config setting), this comment will also be added to the SQL query sent to the database. Often useful for identifying the source of troublesome queries on the database side.
        返回:
        The comment.

      • setComment

        Query<R> setComment​(String comment)
        已过时。
        Set the comment for this query.
        参数:

        返回:
        this, for method chaining
        另请参阅:
        getComment()

      • addQueryHint

        Query<R> addQueryHint​(String hint)
        已过时。
        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.
        参数:
        hint - The database specific query hint to add.

      • iterate

        Iterator<R> iterate()
        已过时。
        Return the query results as an Iterator. If the query contains multiple results per row, the results are returned in an instance of Object[].

        Entities returned as results are initialized on demand. The first SQL query returns identifiers only.
        返回:
        the result iterator

      • scroll

        ScrollableResults scroll()
        已过时。
        Return the query results as ScrollableResults. The scrollability of the returned results depends upon JDBC driver support for scrollable ResultSets.

        You should call ScrollableResults.close() after processing the ScrollableResults so that the underlying resources are deallocated right away.

        返回:
        the result iterator
        另请参阅:
        ScrollableResults

      • scroll

        ScrollableResults scroll​(ScrollMode scrollMode)
        已过时。
        Return the query results as ScrollableResults. The scrollability of the returned results depends upon JDBC driver support for scrollable ResultSets.

        参数:
        scrollMode - The scroll mode
        返回:
        the result iterator
        另请参阅:
        ScrollableResults, ScrollMode

      • list

        List<R> list()
        已过时。

        返回:
        the single result or null
        抛出:
        NonUniqueResultException - if there is more than one matching result
