Changelog of @hackage/DBFunctor 0.1.2.1

# Changelog for DBFunctor

0.1.0.0

  • Initial Version. Includes a full-working version of
    • Julius: A type-level Embedded Domain Specific (EDSL) Language for ETL
    • all common Relational Algebra operations,
    • the ETL Mapping and other typical ETL constructs and operations
    • operations applicable to all kinds of tabular data
    • In-memory, database-less data processing.

0.1.1.0

  • Includes various enhancements (most notable is DML operations support) and fixes
    • Issue #1: Implemented agg function string_agg (listagg in Oracle) and the corresponding Julius clause
    • Issue #2: Implemented Julius Aggregate clauses: CountDist and CountStar
    • Issue #6 DML Enhancements
      • Implement Update Julius Clause
      • Implement Insert Operation and corresponding Julius Clause (both single RTuple INSERT and INSERT INTO SELECT)
      • Implement Merge/Upsert operation and corresponding Julius clause
      • Implement semi-join operation and corresponding Julius clause
      • Implement anti-join operation and corresponding Julius clause
      • Implement Delete operation and corresponding Julius clause
    • Issue #5 : Add support for UTCTime
    • Solve the CSV orphan instances problem by defining CSV with newtype
    • Fix problem with order by. I have noticed the following bug: 
								>>> let t1 = RDate {rdate = "01/12/1990", dtformat = "DD/MM/YYYY"}
								>>> let t2 = RDate {rdate = "1/12/1991", dtformat = "DD/MM/YYYY"}
								>>>	compare t1 t2
								>>>	EQ

Fix:

  • Redefine the RDataType Ord instance based on the compare function instead of the (<=) function.
  • When comparing RDate types, convert them first to RTimeStamps and then compare these ones
  • The previous point apply it also to the Eq instance for RDataType.
