+ * Caché 2007.1 dialect. This class is required in order to use Hibernate with
Intersystems Cach� SQL.<br>
+ * <br>
+ * Compatible with Cach� 2007.1.
+ * Cache JDBC driver version ?.?.
+ * <br>
+ * <head>
+ * <title>Caché and Hibernate</title>
+ * </head>
+ * <body>
+ * <h1>Caché and Hibernate</h1>
+ * <h2>PREREQUISITES</h2>
+ * These setup instructions assume that both Caché and Hibernate are installed
and operational.
+ * <br>
+ * <h2>HIBERNATE DIRECTORIES AND FILES</h2>
+ * InterSystems support for Hibernate 2.1.8 and Hibernate 3.0.5
+ * requires different dialect files from those distributed with Hibernate 3.2.
+ * Also Hibernate 2.1.8 has a different directory and Java package structure which is
reflected in the InterSystems sources.
+ * JBoss distributes the InterSystems Cache' dialect for Hibernate 3.2.
+ * For earlier versions of Hibernate please contact
+ * <a
href="http://www.intersystems.com/support/cache-support.html"&g...
Worldwide Response Center</A> (WRC)
+ * for the appropriate source files.
+ * <br>
+ * <h2>CACHÉ DOCUMENTATION</h2>
+ * Documentation for Caché is available online when Caché is
running.
+ * It can also be obtained from the
+ * <a
href="http://www.intersystems.com/cache/downloads/documentation.html...
website.
+ * The book, "Object-oriented Application Development Using the Caché
Post-relational Database:
+ * is also available from Springer-Verlag.
+ * <br>
+ * <h2>HIBERNATE DOCUMENTATION</h2>
+ * Hibernate comes with extensive electronic documentation.
+ * In addition, several books on Hibernate are available from
+ * <a href="http://www.manning.com">Manning Publications Co</a>.
+ * Three available titles are "Hibernate Quickly", "Hibernate in
Action", and "Java Persistence with Hibernate".
+ * <br>
+ * <h2>TO SET UP HIBERNATE FOR USE WITH CACHÉ</h2>
+ * The following steps assume that the directory where Caché was installed is
C:\CacheSys.
+ * This is the default installation directory for Caché.
+ * The default installation directory for Hibernate is assumed to be C:\Hibernate.
+ * <p/>
+ * If either product is installed in a different location, the pathnames that follow
should be modified appropriately.
+ * <p/>
+ * Caché version 2007.1 and above is recommended for use with
+ * Hibernate. The next step depends on the location of your
+ * CacheDB.jar depending on your version of Caché.
+ * <ol>
+ * <li>Copy C:\CacheSys\dev\java\lib\CacheDB.jar to
C:\Hibernate\lib\CacheDB.jar.</li>
+ * <li>Copy C:\CacheSys\dev\java\lib\JDK15\CacheDB.jar to
C:\Hibernate\lib\CacheDB.jar.</li>
+ * <p/>
+ * <li>Insert the following files into your Java classpath:
+ * <p/>
+ * <ul>
+ * <li>All jar files in the directory C:\Hibernate\lib</li>
+ * <li>The directory (or directories) where hibernate.properties and/or
hibernate.cfg.xml are kept.</li>
+ * </ul>
+ * </li>
+ * <p/>
+ * <li>In the file, hibernate.properties (or hibernate.cfg.xml),
+ * specify the Caché dialect and the Caché version URL
settings.</li>
+ * </ol>
+ * <p/>
+ * For example, in Hibernate 3.2, typical entries in hibernate.properties would have the
following
+ * "name=value" pairs:
+ * <p/>
+ * <table cols=3 border cellpadding=5 cellspacing=0>
+ * <tr>
+ * <th>Property Name</th>
+ * <th>Property Value 3.2</th>
+ * <th>Property Value 2.1.8</th>
+ * </tr>
+ * <tr>
+ * <td>hibernate.dialect</td>
+ * <td>org.hibernate.dialect.Cache71Dialect</td>
+ * <td>net.sf.hibernate.dialect.Cache50Dialect</td>
+ * </tr>
+ * <tr>
+ * <td>hibernate.connection.driver_class</td>
+ * <td>com.intersys.jdbc.CacheDriver</td>
+ * <td>com.intersys.jdbc.CacheDriver</td>
+ * </tr>
+ * <tr>
+ * <td>hibernate.connection.username</td>
+ * <td>(see note 1)</td>
+ * <td>(see note 1)</td>
+ * </tr>
+ * <tr>
+ * <td>hibernate.connection.password</td>
+ * <td>(see note 1)</td>
+ * <td>(see note 1)</td>
+ * </tr>
+ * <tr>
+ * <td>hibernate.connection.url</td>
+ * <td>jdbc:Cache://127.0.0.1:1972/USER</td>
+ * <td>jdbc:Cache://127.0.0.1:1972/USER</td>
+ * </tr>
+ * </table>
+ * <p/>
+ * <dl>
+ * <dt><b>Note 1</b></dt>
+ * <dd>Please contact your administrator for the userid and password you should use
when attempting access via JDBC.
+ * By default, these are chosen to be "_SYSTEM" and "SYS"
respectively as noted in the SQL standard.</dd>
+ * </dl>
+ * <br>
+ * <h2>CACHÉ VERSION URL</h2>
+ * This is the standard URL for the JDBC driver.
+ * For a JDBC driver on the machine hosting Caché, use the IP
"loopback" address, 127.0.0.1.
+ * For 1972, the default port, specify the super server port of your Caché
instance.
+ * For USER, substitute the NAMESPACE which contains your Caché database
data.
+ * <br>
+ * <h2>CACHÉ DIALECTS</h2>
+ * Choices for Dialect are:
+ * <br>
+ * <p/>
+ * <ol>
+ * <li>
+ * org.hibernate.dialect.Cache50Dialect (requires Caché
+ * 5.0 or above)
+ * </li>
+ * <p/>
+ * <li>org.hibernate.dialect.Cache51Dialect (requires Caché 5.1 or
+ * above)</li>
+ * <p/>
+ * <li>org.hibernate.dialect.Cache51SequenceDialect (requires Caché 5.1
or
+ * above)</li>
+ * <p/>
+ * <li>org.hibernate.dialect.Cache71Dialect (requires Caché
+ * 2007.1 or above)</li>
+ * <p/>
+ * <li>org.hibernate.dialect.Cache71SequenceDialect (requires Caché
+ * 2007.1 or above)</li>
+ * </ol>
+ * <p/>
+ * Setting up for Caché 5.0 is similar except that the hibernate
+ * dialect package is "org.hibernate.dialect.Cache50Dialect"
+ * <br>
+ * <h2>SETTING UP CACHÉ DIALECT FROM INTERSYSTEMS SOURCES</h2>
+ * <p/>
+ * InterSystems provides source code for the Hibernate Dialect classes.
+ * Therefore, you must first place the source code in the proper locations
+ * and compile it into Java class files.
+ * Doing this will eliminate possible version mismatches in the compiled Java code.
+ * <p/>
+ * To begin, unzip the InterSystems source into the PARENT directory of the location
where you installed Hibernate.
+ * The InterSystems zip file that contains InterSystems Hibernate support for
+ * Hibernate 2.1.8 and Hibernate 3.0.5 already contains hibernate-2.1
+ * and hibernate-3.0 in its directory structure. This is why you must
+ * unzip to the directory CONTAINING your Hibernate install directory.
+ * <p/>
+ * If you are using Hibernate 3.2, JBoss has already built the right JAR file for you.
+ * If you are NOT using Hibernate 3.2, then you must do the following:
+ * <p/>
+ * <ol>
+ * <li>In your Hibernate install directory, after the unzip we described above,
+ * type the following:
+ * <br>
+ * <pre>
+ * build
+ * </pre></li>
+ * <li>Copy the JAR file to the proper place.
+ * <p/>
+ * For Hibernate 3.0.5, copy
+ * <pre>
+ * ..\hibernate\hibernate3.jar
+ * </pre>
+ * to the Hibernate install directory.
+ * <p/>
+ * For Hibernate 2.1.8, copy
+ * <pre>
+ * ..\hibernate\hibernate.2jar
+ * </pre>
+ * to the Hibernate install directory.</li>
+ * <p/>
+ * <li>Test your installation by configuring etc\hibernate.properties for your
Caché database,
+ * and then running the following:
+ * <pre>
+ * build eg
+ * </pre>
+ * The build process reports its success or failure. If you see,
+ * <pre>
+ * BUILD FAILED
+ * </pre>
+ * please contact the
+ * <a
href="http://www.intersystems.com/support/cache-support.html"&g...
Worldwide Response Center</A>
+ * for assistance.
+ * </li>
+ * </ol>
+ * <br>
+ * <h2>SUPPORT FOR IDENTITY COLUMNS</h2>
+ * Caché 5.1 or later supports identity columns. This includes Cache'
2007.1. To cause
+ * Hibernate to use identity columns, specify "native" as the
+ * generator. Also make sure that
+ * hibernate.jdbc.use_get_generated_keys is set to true, which is the
+ * default. In the Cache' 2007.1 release, with the
+ * Cache71Dialect, you can set hibernate.jdbc.use_get_generated_keys to
+ * false, and still use identity columns.
+ * <br>
+ * <h2>SEQUENCE DIALECTS SUPPORT SEQUENCES</h2>
+ * You do not have to use the sequence dialects with Caché.
+ * These are Cache50SequenceDialect, Cache51SequenceDialect and Cache71SequenceDialect.
+ * But if you choose to use them, set them up as follows:
+ * <p/>
+ * To use Hibernate sequence support with Caché in a namespace, you must FIRST
load the following file into that namespace:
+ * <pre>
+ * src\org\hibernate\dialect\CacheSequences.xml
+ * </pre>
+ * In your Hibernate mapping you can specify sequence use.
+ * When you are using a Cache' sequence dialect, the type "native" maps to
sequence.
+ * <p/>
+ * For example, the following shows the use of a sequence generator in a Hibernate
mapping:
+ * <pre>
+ * <id name="id" column="uid" type="long"
unsaved-value="null">
+ * <generator class="seqhilo">
+ * <param
name="sequence">EVENTS_SEQ</param>
+ * <param name="max_lo">0</param>
+ * </generator>
+ * </id>
+ * </pre>
+ * <br>
+ * <p/>
+ * Some versions of Hibernate under some circumstances call
+ * getSelectSequenceNextValString() in the dialect. If this happens
+ * you will receive the error message: new MappingException( "Dialect
+ * does not support sequences" ).
+ * <h2>BIGINT SUPPORT</h2>
+ * Caché 5.1 and above supports BIGINT. 2007.1 supports BIGINT.
+ * <p/>
+ * Caché 5.0.x does not have direct BIGINT support.
+ * To imitate BIGINT support in Cache 5.0.x, in the SQL configuration,
+ * remap %INTEGER as follows, to be used by Caché 5.0.x dialects:
+ * <p/>
+ * <pre>
+ * %Library.Integer(MAXVAL=99999999999999999999,MINVAL=-999999999999999999)
+ * </pre>
+ * <p/>
+ * To change SQL settings:
+ * <p/>
+ * <ol>
+ * <li>In Caché 2007.1, use the System Management Portal.</li>
+ * <p/>
+ * <li>In Caché 5.0, use the Configuration Manager.</li>
+ * </ol>
+ * <p/>
+ * Set Caché SQL to allow:
+ * <p/>
+ * <ol>
+ * <li>delimited identifiers</li>
+ * <li>drop of non-existent tables</li>
+ * <li>drop of non-existent constraints</li>
+ * </ol>
+ * <p/>
+ * <h2>HIBERNATE 2.1.8</h2>
+ * Hibernate 2.1.8 requires different source files from InterSystems reflecting
+ * the different directory and Java package structure of Hibernate 2.1.8.
+ * Please contact
+ * <a
href="http://www.intersystems.com/support/cache-support.html"&g...
Worldwide Response Center</A> (WRC)
+ * for these source files if you need to use Hibernate 2.1.8.
+ * <p/>
+ * To run a Cach� application with Hibernate 2.1.8, set the following flag when starting
your JVM:
+ * <pre>
+ * -Dhibernate.jdbc.use_streams_for_binary=false
+ * </pre>
+ * <p/>
+ * In Hibernate 3.0.5, this flag is not necessary;
+ * it is taken care of by the Caché dialect itself.
+ * <br>
+ * <h2>HIBERNATE FILES ASSOCIATED WITH CACHÉ DIALECT</h2>
+ * The following files are associated with Caché dialect:
+ * <p/>
+ * <ol>
+ * <li>src\org\hibernate\dialect\Cache71Dialect.java</li>
+ *
<li>src\org\hibernate\dialect\function\ConditionalParenthesisFunction.java</li>
+ * <li>src\org\hibernate\dialect\function\ConvertFunction.java</li>
+ * <li>src\org\hibernate\exception\CacheSQLStateConverter.java</li>
+ * <li>src\org\hibernate\sql\CacheJoinFragment.java</li>
+ * </ol>
+ * Cache71Dialect ships with Hibernate 3.2. All other dialects are distributed by
InterSystems and subclass Cache71Dialect.
+ * <h2>Limitations</h2>
+ * The following is a list of the currently known limitations of using Cache' with
Hibernate. Please check with InterSystems on the latest status as these are server side
issues.
+ * <p/>
+ * The following also lists known issues with running the full Hibernate regression tests
against InterSystems Cache'.
+ * <p/>
+ * - Delete of self-referential foreign keys.
+ * <p/>
+ * We do not current support deletion of a table row when the table has a foreign key
that references itself and the foreign key in the table row references that table row.
(self-referential foreign keys)
+ * <p/>
+ * - Support for "SELECT FOR UPDATE."
+ * <p/>
+ * The default locking mode strategy for Cache' is Hibernate's
UpdateLockingStrategy, which you use with Hibernate's versioning capability.
+ * <p/>
+ * To use Concurrency modes that requires other locking strategies you can subclass your
Cache' dialect and define a locking strategy.
+ * <p/>
+ * Cache' does not currently support "SELECT FOR UPDATE." While
grammatically correct, it does no locking.
+ * <p/>
+ * In versions prior to 2007.1, there are limitations in support for outer joins (see
Cache' documentation).
+ * <p/>
+ * For example, Cache' prior to 2007.1 does support "NOT NULL" clauses in
the ON conditions.
+ * <p/>
+ * Cache' does not support using longvarbinary or longvarchar in a where clause.
+ * <p/>
+ * In Hibernate regression tests, Baz.hbm.xml, FooBar.hbm.xml, Glarch.hbm.xml and
XY.hbm.xml have to be edited to replace "!" by BANG and "^" by CARET.
Our own identifier translation is not enough since Hibernate uses names containing these
in its own mapping files and Hibernate (on the client-side) does not know about our
server-side mapping.
+ * <p/>
+ * There are some tests that involve batch operations where the test
+ * will succeed if you increase the size of the lock table from
+ * 786432 (the default) to 1786432. You can use the System Management
+ * Portal in 2007.1 or the configuration manager in 5.0.X to increase the
+ * size of the lock table. This requirement of increasing the lock
+ * table size is specific to running the Hibernate regression tests.
+ * <p/>
+ * Cache' fails tests that attempt to COUNT stream fields
+ * <p/>
+ * Here is an example of such an error message, SQL ERROR -37: Aggregate function COUNT
not supported for Stream fields
+ * <p/>
+ * We fail on tests that use mappings like the following
+ * <p/>
+ * <pre>
+ * <property name="yob" formula="year(dob)"/>
+ * </pre>
+ * and the error is:
+ * <p/>
+ * ERROR #359: User defined SQL Function 'SQLUSER.YEAR' does not exist
+ * <p/>
+ * If the mapping is changed to
+ * <p/>
+ * <pre>
+ * <property name="yob" formula="{fn year(dob)}"/>
+ * </pre>
+ * then such tests succeed.
+ * <p/>
+ * Cache' 2007.1 supports temp tables. Prior versions do not.
+ * <p/>
+ * We do not support row valued expression. So WHERE clauses like "WHERE (a,b,c) =
(d,e,f)" give syntax errors. The Hibernate regression tests use row valued
expressions and we fail on these.
+ * <p/>
+ * For example:
+ * <p/>
+ * <pre>
+ * result = s.createQuery("from Transaction txn where txn.value = (1.5,
'AUD')").list();
+ * </pre>
+ * will not generate valid Cache' SQL because of the parenthesis around (1.5,
'AUD')
+ * <p/>
+ * Queries like the following:
+ * <p/>
+ * <pre>
+ * session.createQuery("select extract(second from current_timestamp()),
extract(minute from current_timestamp()), extract(hour from current_timestamp()) from
Mammal m").list();
+ * </pre>
+ * <p/>
+ * will not work, because we do support "extract" function.
+ * <p/>
+ * We do not support in () (empty parenthesis)
+ * <p/>
+ * We do not guarantee the case of a column returned using a group by clause.
+ * <p/>
+ * For instance in the regression test,
+ * <p/>
+ * <pre>
+ * list = s.find("select new Result( baz.name, max(foo.long), count(foo) ) from Baz
baz join baz.fooArray foo group by baz.name");
+ * </pre>
+ * we return baz.name in lower case, and the test that generates this SQL fails.
