</li><li>If large result sets (backed by a temporary file) where not closed, the file was not deleted.
Now, the default result set type is FETCH_FORWARD. This means temp files are deleted
automatically (without having to close the result set explicitly). But it also means

ResultSet.beforeFirst can only be called for scrollable result sets. To create a scrollable result set,

<h3>Version 0.9 / 2006-07-14 (Build 16)</h3><ul>
<li>
The regression tests are no longer included in the jar file. This reduces the size by about 200 KB.
</li><li>
Fixed some bugs in the CSV tool. This tool should now work for most cases, but is still not fully tested.
</li><li>
The cache size is now measured in blocks and no longer in rows. Manually setting
the cache size is no longer necessary in most cases.
</li><li>
Objects of unknown type are no longer serialized to a byte array (and deserialized when calling getObject on a byte array data type)
by default. This behavior can be changed with Constants.SERIALIZE_JAVA_OBJECTS = true
</li><li>
New column IS_GENERATED in the metadata tables SEQUENCES and INDEXES
</li><li>
Optimization: deterministic subqueries are evaluated only once.
</li><li>
An exception was thrown if a scalar subquery returned no rows. Now the NULL value is used in this case.
</li><li>
IF EXISTS / IF NOT EXISTS implemented for the remaining CREATE / DROP statements.
</li><li>
ResultSetMetaData.isNullable is now implemented.
</li><li>
LIKE ... ESCAPE: The escape character may now also be an expression.
</li><li>
Compatibility: TRIM(whitespace FROM string)
</li><li>
Compatibility: SUBSTRING(string FROM start FOR length)
</li><li>
CREATE VIEW now supports a column list: CREATE VIEW TEST_V(A, B) AS ...
</li><li>
Compatibility: 'T', 'Y', 'YES', 'F', 'N', 'NO' (case insensitive) can now also be converted to boolean.
This is allowed now: WHERE BOOLEAN_FIELD='T'=(ID>1)
</li><li>
Optimization: data conversion of constants was not optimized. This is done now.
</li><li>
Compatibility: Implemented a shortcut version to declare single column referential integrity:
CREATE TABLE TEST(ID INT PRIMARY KEY, PARENT INT REFERENCES TEST)
</li><li>
Issue #126: It is possible to create multiple primary keys for the same table.
</li><li>
Issue #125: Foreign key constraints of local temporary tables are not dropped when the table is dropped.
</li><li>
Issue #124: Adding a column didn't work when the table contains a referential integrity check.
</li><li>
Issue #123: The connection to the server is lost if an abnormal exception occurs.
Example SQL statement: select 1=(1,2)
</li><li>
The H2 Console didn't parse statements containing '-' or '/' correctly. Fixed.
Now uses the same facility to split a script into SQL statements for
the RunScript tool, for the RUNSCRIPT command and for the H2 Console.
</li><li>
DatabaseMetaData.getTypeInfo: BIGINT was returning AUTO_INCREMENT=TRUE, which is wrong. Fixed.
</li></ul>
<h3>Version 0.9 / 2006-07-01 (Build 14)</h3><ul>
<li>
After dropping constraints and altering a table sometimes the database could not be opened. Fixed.
</li><li>
Outer joins did not always use an index even if this was possible. Fixed.
</li><li>
Issue #122: Using OFFSET in big result sets (disk buffered result sets) did not work. Fixed.
</li><li>
Support DatabaseMetaData.getSuperTables (currently returns an empty result set in every case).
</li><li>
Database names are no longer case sensitive for the Windows operating system,
because there the files names are not case sensitive.
</li><li>
If an index is created for a constraint, this index now belong to the constraint and is removed when removing the constraint.
</li><li>
Issue #121: Using a quoted table or alias name in front of a column name (SELECT "TEST".ID FROM TEST) didn't work.
</li><li>
Issue #120: Some ALTER TABLE statements didn't work when the table was in another than the main schema. Fixed.
</li><li>
Issue #119: If a table with autoincrement column is created in another schema,
it was not possible to connect to the database again.
Now opening a database first sorts the script by object type.
</li><li>
Issue #118: ALTER TABLE RENAME COLUMN doesn't work correctly. Workaround: don't use it.
</li><li>
Cache: implemented a String cache and improved the Value cache. Now uses a weak reference
to avoid OutOfMemory due to caching values.
</li><li>
Server: changed the public API a bit to allow an application to deal easier with start problems.
Now instead of Server.startTcpServer(args) use Server.createTcpServer(args).start();
</li><li>
Issue #117: Server.start...Server sometimes returned before the server was started. Solved.
</li><li>
Issue #116: Server: reduces memory usage. Reduced number of cached objects per connection.
</li><li>
Improved trace messages, and trace now starts earlier (when opening the database).
</li><li>
Simplified translation of the Web Console (a tool to convert the translation files to UTF-8).
</li><li>
Newsfeed sample application (used to create the newsfeed and newsletter).
</li><li>
New functions: MEMORY_FREE() and MEMORY_USED().
</li></ul>
