v1.2.0

Summary 🕙

This release is highlighted by the addition of the interval data type and the let clause.

• Added support for SQL-standard interval data types (i.e. YEAR, MONTH, DAY, HOUR, etc.) in PartiQL. Users can now perform complex date calculations such as DATE '2025-01-01' + INTERVAL '1-5' YEAR TO MONTH and TIME '12:30:01.05' + INTERVAL '5:2:1.345' HOUR TO SECOND.
• Added support for the LET clause, enabling users to write queries such as:

SELECT area * c.height AS volume
FROM cylinders c
LET 3.14 * c.radius * c.radius AS area;

v1.1.0

v1.1.0 - Valentine's Day Release 💘

Summary

This release is highlighted by the addition of support for parsing, planning, and execution of basic Common Table Expressions (CTEs).

These basic CTEs do not allow for the planning/execution of:

1. RECURSIVE
2. the with column list
3. the ability to reference CTEs from other CTEs

These features may be added in a subsequent release. If you're interested in one of these features, please let us know!

Changelog

• Adds -SNAPSHOT; upgrade to v1.0.1 by @alancai98 in #1731
• Adds parsing and modeling of CTEs by @johnedquinn in #1736
  • Also fixes the parsing of select statements and bag operations as they pertain to the expression tree.
• Fix: Properly return properties from Session by @jpschorr in #1739
• Adds planning and evaluation support for CTEs by @johnedquinn in #1738
• Releases v1.1.0 by @johnedquinn in #1740

v0.14.9

Changed

• With full, closed schema, the planner will now give a plan-time warning when it can prove an exclude path will never
  exclude a value (relevant issue -- partiql/partiql-lang#91).

Experimental Changes

• BREAKING: For the experimental org.partiql.lang.domains of PartiqlLogical, PartiqlLogicalResolved, and PartiqlPhysical,
  the modeling of DML has changed substantially. These changes, while considered breaking changes, are part of an
  experimental area of the PartiQL library and thus do not mandate a major-version bump of this library. Consumers
  of these experimental APIs should be wary of these changes.

v0.14.8

Fixed

• Case When Branch inference will preserve type constraint for String Type and Decimal Type, if no coercion is required

Contributors

Thank you to all who have contributed!

• @yliuuuu

v0.14.7

Fixed

• partiql-lang's PartiQLParserBuilder.standard() will use the ANTLR dependency from partiql-parser to
  prevent NoSuchMethodErrors

Contributors

• @alancai98

v0.14.6

Added

• Adds PartiQLValueTextWriter implementation of date, time, and timestamp values
• Shades ANTLR dependency to avoid dependency conflicts.

Changed

• Behavioral change: The INTEGER/INT type is now an alias to the INT4 type. Previously the INTEGER type was
  unconstrained which is not SQL-conformant and is causing issues in integrating with other systems. This release makes
  INTEGER an alias for INT4 which is the internal type name. In a later release, we will make INTEGER the default 32-bit
  integer with INT/INT4/INTEGER4 being aliases per other systems. This change only applies to
  org.partiql.parser.PartiQLParser, not the org.partiql.lang.syntax.PartiQLParser.
• Breaking change: partiql-plan: adds a set quantifier field to SQL set operators UNION, INTERSECT, and EXCEPT
• partiql-plan: adds a dedicated Rex node for PartiQL bag operators UNION, INTERSECT, and EXCEPT
• partiql-planner: Adds typing support for set operators
• partiql-parser: parses non-SFW expressions to be PartiQL OUTER bag operators
• partiql-ast: fixes missing parens from bag_op when printing using SqlDialect

Fixed

• Fixed classpath conflict for IsStaticTypeMeta
• Fixes ANTLR parser grammar file naming.
