HTSQL 2.1.1 is released
Published by cce on 2011-08-30
This is the final release of HTSQL 2.1 aka “Query Power”. This release
focuses on supporting analytical queries with projections and calculated
attributes.
Major changes since the 2.0 release:
- Added MySQL, Oracle and MS SQL Server backends, in addition to
existing SQLite and PostgreSQL backends.
- Added support for projections (see Introducing Projections).
- Added support for calculated attributes and references (see
Introducing Calculated Attributes and
Introducing References).
- Streamlined HTSQL grammar and semantics, added support for time and
datetime data types, and many other improvements.
Changes since 2.1rc1 include:
- General code cleanup and refactoring.
- Improved emitted SQL for projections and aggregates.
- Changed operator precedence to avoid parentheses around
filtering and projection operators.
- Added a test data generator for HTSQL regression tests
(thank to Yuri Yerokhin).
- Added support for hierarchical headers for /:txt and /:html
formatters.
