Breaking changes:

  • Added log_category parameter to log function, #86
  • verbatim_clause replaces verbatim if used as a clause in a custom query

Other changes:

  • add .as<"my_name">() overload (requires C++26 with reflection), #99
  • deprecate result_row_t::as_tuple
  • new as_tuple(const result_row_t&)
  • new get_sql_name_tuple(const result_row_t&), #72
  • sqlpp23-ddl2cpp changes:
    • command-line option --path-to-datatype-file was renamed to --path-to-custom-types
    • if an error is found in the custom types file, the program exits with error code 30
    • base types in the custom types file should use snake_case, although the old CamelCase is still supported for backwards compatibility
    • renamed some base types in custom types file to match the corresponding sqlpp23 data types:
      • integer -> integral
      • date_time -> timestamp
    • documented the format of the custom types file
    • recognize and process "ALTER TABLE...ALTER COLUMN...SET DEFAULT" commands, which improves processing of pg_dump output scripts.
    • forbid order_by, limit, offset, and for_update in union arguments (while mysql and postgresql would allow order_by, limit, and offset if the arguments and enclosed in parentheses, these clauses are not allowed in sqlite3 and parentheses aren't allowed either)
    • add order_by, limit, and offset to union expressions, e.g. lhs.union(rhs).order_by(t.id).limit(10).offset(10)
    • forbid expressions that require tables in limit and offset, e.g. limit(t.id)

0.67

Module support

  • Basic support for modules, see docs, #30
  • core/name/create_name_tag.h is now a stand-alone header, #30
  • Revamped commandline switches for sqlpp23-ddl2cpp, see docs
  • Instead of cte(sqlpp::alias::a), you now have to call sqlpp::cte(sqlpp::alias::a)
  • Support comparison member functions for comparison expressions, e.g. you can now order by comparison results, #39
  • order_by allows duplicate expressions, #39
  • Install modules into <prefix>/modules/sqlpp23, #58

0.66

First release of sqlpp23

It is tagged 0.66 as it is a continuation from sqlpp11-0.65.

Major differences for library users are documented in docs/differences_to_sqlpp11.md

Beyond that, the switch to C++23 makes the library easier to maintain, easier to extend, and (I think) easier to read. One of the nicest features of C++23 in this regard is "Deducing this" (P0847R7) as it makes CRTP significantly simpler to write and reason about.

See for instance

  • statement_t: include/sqlpp23/core/query/statement.h
  • all clauses: include/sqlpp23/core/clause/*.h
