Title: Release Notes for Derby 10.4.1.0

Release Notes for Derby 10.4.1.0

These notes describe the difference between Derby release 10.4.1.0 and the preceding release 10.3.2.1.

Overview

Derby is a pure Java relational database engine using standard SQL and JDBC as its APIs.

Derby functionality includes:

  • Embedded engine with JDBC drivers
  • Network Server
  • Network client JDBC drivers
  • Command line tools: ij (SQL scripting), dblook (schema dump) and sysinfo (system info)

New Features

This is a feature release. The following new features were added:

  • SQL ROW_NUMBER() window function, as described in the SQL 2003 standard section 6.10, for an empty, inlined window specification. The window clause, as described in section 7.11 is not implemented
    • .
  • Unique constraints on nullable columns. Feature T591.
  • Asynchronous replication with manual fail-over.
  • VTI Table Functions.
  • Java Management Extensions (JMX) for Derby, allowing local and remote monitoring and management of a running Derby system (this release includes a basic set of MBeans - it is expected that more JMX functionality will be added in later releases).
  • SQL bracketed comments (/*..*/) Feature T351.
  • ij continuation marker. interactive ij shows > prompt until ;
  • A JDBC statement object cache in the client driver.
  • Cache the isolation level and the current schema in the client driver.
  • Implement a new multi-threaded buffer manager to get better scalability on machines with multiple CPUs or multiple cores.

Issues

Compared with the previous release (10.3.2.1), Derby release 10.4.1.0 introduces the following new features and incompatibilities. These merit your special attention.

Note for DERBY-3301

Summary of Change

Queries with nested EXIST, ANY or IN clauses now return correct results.

Symptoms Seen by Applications Affected by Change

In the previous release, applications that executed SQL statements containing nested EXISTS, ANY or IN clauses could see fewer rows than those satisfying the query. In particular, rows that had the same value for one of the selected columns as another row might not have been returned.

Incompatibilities with Previous Release

None.

Rationale for Change

The previous behavior violated the ANSI SQL standard. The new behavior is correct.

Application Changes Required

Typically none, but applications must handle that the correct results are now returned.

Note for DERBY-3026

Summary of Change

The frameworks directory (and its contents) has been removed.

Symptoms Seen by Applications Affected by Change

Users and applications that rely on any of the scripts or HTML files in the frameworks directory (which has been deprecated since the 10.2.1.6 release) or any of its subdirectories will no longer be able to find those files in the same location.

Incompatibilities with Previous Release

Applications or commands referencing files in the frameworks directory will fail.

Rationale for Change

In the 10.2.1.6 release, new and improved scripts were added in a new bin directory, intended to replace the scripts in the frameworks directory. The new scripts follow Apache conventions, and all scripts are located in a single directory, making them easier to find. Removing the old and deprecated scripts and the frameworks directory itself will eliminate a potential source of confusion and annoyance among users.

The frameworks directory has been deprecated since the 10.2.1.6 release, and has not been maintained since then. The 10.2.1.6 release notes announced the deprecation of the scripts in the frameworks directory, and an additional file (frameworks.DEPRECATED.txt) was added in the top-level directory of the 10.3.1.4 release, with the purpose of alerting users about this change. A warning message was also added to the scripts in the frameworks directory at the same time.

Application Changes Required

All references to the frameworks directory or its contents must be updated. The scripts in the bin directory may be used instead of the old scripts.

Note for DERBY-3013

Summary of Change

The column default value can now also be specified as CURRENT_USER or SESSION_USER.

Symptoms Seen by Applications Affected by Change

None

Incompatibilities with Previous Release

None

Rationale for Change

Extend Derby's support for standard SQL constructions.

Application Changes Required

None.

Note for DERBY-2967

Summary of Change

Databases with territory based collation might see the behavior of LIKE predicate in WHERE clause has changed.

Symptoms Seen by Applications Affected by Change

In territory based databases, the LIKE predicate will now comply with SQL specification(Derby already follows SQL specification for UCS_BASIC databases). SQL specification for LIKE predicate requires that database should do one character comparison at a time. Prior to the fix that went in as part of DERBY-2967, Derby did string comparison rather than character comparison for LIKE. This causes a problem with territory based database because the collation element(s) for a string of characters may not be same as the collation element(s) for inidivdual characters that make up that string. In addition, the metacharacter _ in the pattern in a LIKE predicate will now consume exactly one character rather than working on number of collation elements. To show the impact on application, consider following eg. Say we are working with a territory where character 'z' has same collation elements as 'xy'. For such a territory consider following LIKE predicate 'zcb' LIKE 'xy_b' Prior to DERBY-2967, Derby will return TRUE because collation elements for 'z' matched 'xy' and 'c' was consumed by '_' and 'b' matched 'b'. But this does not follow SQL specification. SQL specification requires one character comparison at a time in LIKE. With the fix for DERBY-2967, the LIKE predicate in this example will return FALSE because the collation element(s) for 'z' does not match collation element(s) for 'x'. In addition, the metacharacter _ in pattern for LIKE will consume *one* character in the string value. So for an eg clause 'xycb' LIKE '_cb' will return FALSE because metacharacter _ will consume 'x' and since 'c' does not match 'y', Derby will return FALSE.

Rationale for Change

The previous behavior violated the SQL specification. The new behavior is correct.

Note for DERBY-2925

Summary of Change

Prevent export from overwriting existing files

Symptoms Seen by Applications Affected by Change

Due to security concerns, and to avoid accidental file damage, Export processing will not overwrite existing files. As a result, applications may observe some behavioral changes with respect to Export operations.

Incompatibilities with Previous Release

  1. SYSCS_UTIL.SYSCS_EXPORT_TABLE: Exports of all the data from a table to an existing file is no longer possible and the user/application must remove the existing file, otherwise ERROR XIE0S will be returned.
  2. SYSCS_UTIL.SYSCS_EXPORT_QUERY: Exports of all the data returned from the SELECT statement to an existing file is no longer possible and the user/application must remove the existing file, otherwise ERROR XIE0S will be returned.
  3. SYSCS_UTIL.SYSCS_EXPORT_QUERY_LOBS_TO_EXTFILE: Export of the result of a SELECT statement to a main data output file, and the LOB data into a large object auxiliary file to an existing file is no longer possible and the user/application must remove the existing data file and/or large object auxiliary file, otherwise ERROR XIE0S will be returned if the data file exists or ERROR XIE0T will be returned if the large object auxiliary file exists.

Rationale for Change

Due to security concerns and to avoid accidental file damage, Export processing will no longer overwrite an existing file.

Application Changes Required

The application needs to specify a different filename which does not exists or delete the existing file before performing the Export operation.

Note for DERBY-2892

Summary of Change

DERBY-2892 fixes the bug: "Closing a resultset after retrieving a large > 32665 bytes value with Network Server does not release locks." The fix changes the JDBC retrieval of BLOB/CLOB columns release locks and the lob locator after calls to ResultSet.getString(), ResultSet.getCharacterStream(), ResultSet.getBytes() or ResultSet.getBinaryStream(). Previously locks would remain held after these calls. Note: Locks will still be held for calls to ResultSet.getClob() or ResultSet.getBlob(). The user must call free() or commit or rollback the transation to release these locks.

Symptoms Seen by Applications Affected by Change

Users will no longer see locks being held for calls to ResultSet.getString(), ResultSet.getCharacterStream(), ResultSet.getBytes() or ResultSet.getBinaryStream().

Incompatibilities with Previous Release

As part of the implementation of this change, BLOB/CLOB columns can be retrieved only once through JDBC, for each row. For example, if the user calls ResultSet.getString() on a BLOB or CLOB column, they cannot make a subsequent call to ResultSet.getCharacterStream() for the same column on the same row. An Exception will be thrown if this is attempted.

Rationale for Change

In order to ensure the proper locking behavior, the change to throw an exception when a BLOB/CLOB column is retrieved more than once for a row was required.

Application Changes Required

Users should retrieve the field only once and save the value for reuse, rather than making multiple calls to ResultSet.getXXXX methods.

Note for DERBY-2351

Summary of Change

An ORDER BY clause of a DISTINCT query which specifies to order by a column which was not in the DISTINCT list is now rejected, because the intent of the query is ambiguous. Previously, Derby instead produced non-distinct results. Also, an ORDER BY clause which specifies a table-name-qualified column alias is now rejected as invalid, where previously it was accepted.

Symptoms Seen by Applications Affected by Change

New rules for DISTINCT and ORDER BY

Applications which specify certain combinations of SELECT DISTINCT with ORDER BY will now receive an error message, whereas formerly such applications received non-distinct results.

As an example, take the following:

create table person (name varchar(10), age int);
insert into person values ('John', 10);
insert into person values ('John', 30);
insert into person values ('Mary', 20);

SELECT DISTINCT name FROM person ORDER BY age;

The query above is now rejected, with the error message:

ERROR 42879: The ORDER BY clause may not contain column 'AGE', since the query specifies DISTINCT and that column does not appear in the query result.

If the AGE column is included in the DISTINCT list in the above query, there is no ambiguity

New column alias rules

Applications which specify a column alias for a column in the SELECT statement, and which specify an ORDER BY clause which specifies that column alias qualified by the table name, will now receive an error indicating that the ORDER BY clause is invalid.

As an example, take the following:

create table t1 (i int, j int);
select t1.id as idcolumn1, t1.id as idcolumn2 from t1 order by t1.idcolumn1, t1.idcolumn2;

This query is now rejected, as there is no column named 'idcolumn1' in table 't1'. The error message is:

ERROR 42X04: Column 'T1.IDCOLUMN1' is either not in any table in the FROM list or appears within a join specification and is outside the scope of the join specification or appears in a HAVING clause and is not in the GROUP BY list. If this is a CREATE or ALTER TABLE statement then 'T1.IDCOLUMN1' is not a column in the target table.

Valid forms of the query above are:

select t1.id as idcolumn1, t1.id as idcolumn2 from t1 order by idcolumn1, idcolumn2;

or

select t1.id as idcolumn1, t1.id as idcolumn2 from t1 order by t1.id, t1.id;

Rationale for Change

When the query ambiguously specifies both DISTINCT and ORDER BY, Derby was unsure whether to return the rows properly ordered, but non-distinct, or to return a distinct set of rows, but in an unknown order. Since no clear resolution of the ambiguity could be found, we chose instead to reject the query.

The rules for resolving column references in ORDER BY clauses have been enhanced to consider column aliases and column names more fully. Derby now uses different resolution rules depending on whether the ORDER BY column reference is table.column, or just column:

  • if the table name is provided, we match against the underlying table name, and don't consider any aliases
  • if the table name is NOT provided, we first match against the alias name, if present, and if no alias name matches then we match against the underlying source column name.

Application Changes Required

A query which specifies ordering by a non-distinct column should instead include the ORDER BY column in the DISTINCT list, to resolve the ambiguity about which values of that column should be used to distinctly identify the resulting rows.

A query which specifies table-name.alias-name should be rewritten to specify either simply alias-name, or table-name.column-name.

Note for DERBY-2065

Summary of Change

Error code changed for embedded connection when a connection with an open transaction is attempted closed.

Symptoms Seen by Applications Affected by Change

In the previous release, calling Connection.close() on a connection with an open transaction raised an error with error code 25001 with the client driver, whereas the embedded driver raised error code 25000. The embedded driver has now been changed to raise the same error code as the client driver, i.e. 25001, as specified by the SQL standard.

Incompatibilities with Previous Release

Embedded applications that are dependent on the error code ever being "25000" could start failing. Embedded applications that are dependent on the error code never being "25001" could start failing.

Rationale for Change

Harmonize error codes raised by the client and embedded drivers, thereby also making the embedded driver compatible with the SQL standard.

Application Changes Required

Applications that are dependent on the error code must be changed to expect the new code.

Build Environment

Derby release 10.4.1.0 was built using the following environment:

  • Branch - Source code came from the 10.4 branch.
  • Machine - SunOS khepri32 5.10 Generic_127112-01 i86pc i386 i86pc
  • Ant - Apache Ant version 1.7.0 compiled on December 13 2006
  • JDK 1.4 - java version "1.4.2_05" Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_05-b04) Java HotSpot(TM) Client VM (build 1.4.2_05-b04, mixed mode)
  • Java 6 - java version "1.6.0_04" Java(TM) SE Runtime Environment (build 1.6.0_04-b06) Java HotSpot(TM) Server VM (build 10.0-b18, mixed mode)
  • OSGi - The felix.jar was used to build org.apache.derby.osgi.EmbeddedActivator.
  • Compiler - The 1.4.2_05 javac was used to compile all classes except for the JDBC4 drivers. The JDBC4 driver classes were compiled using the 1.6.0_04 javac.
  • JSR 169 - J2ME support was built using java.sun.com/j2me (cdc-1_1-fr-ri, jdbc_cdc1.0).
There seems to be a small glitch that messes up release note
processing for DERBY-2892 and DERBY-2351. Part of the release note
description seems to be included in the bulleted list of issues. Don't
know if the problem is in releaseNote.html or in the generator,
though... 

There is obviously no release note for DERBY-3023. I have used
the updated filters to produce the lists of Jira issues, so only issues
that have checked 'release note needed' have had their
'releaseNote.html' processed and included. I have not included the
improvement issues in the 'Fixed bugs' list (as dsicussed in another
thread).
