[Tarantool-patches] [PATCH v2 0/6] sql: extended metadata

[Nikita Pettik]

Branch: https://github.com/tarantool/tarantool/commits/np/gh-4407-extend-sql-metadata
Issue: https://github.com/tarantool/tarantool/issues/4407
v1: https://lists.tarantool.org/pipermail/tarantool-patches/2019-November/012680.html

Changes in v2:
 - introduced pragma full_metadata which allows to turn
   extended metadata on/off. By default only basic
   metadata is send; it allows to avoid massive tests
   refactoring and avoid network overhead for users who don't
   need extended metadata.
 - now alias is always displayed in extended meta: if there's no
   AS clause, then alias is the same as name.
 - moved tests verifing presence of additional metadata to
   separate file.
 - provided test and explanation for second patch
   (sql: fix possible null dereference in sql_expr_coll()).
 - provided doc bot request.

Nikita Pettik (6):
  sql: refactor resulting set metadata
  sql: fix possible null dereference in sql_expr_coll()
  sql: extend result set with collation
  sql: extend result set with nullability
  sql: extend result set with autoincrement
  sql: extend result set with alias
