DBFunctor v0.1.1.0 Release Notes

Release Date: 2019-02-09 // about 5 years ago
    • 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: Haskell >>> 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.
