[Tarantool-patches] [PATCH] sql: use unify pattern for column names

Roman Khabibov roman.habibov at tarantool.org
Mon Mar 9 18:02:58 MSK 2020


Name resulting columns generated by an expression or <VALUES>
construction by the "_COLUMN_N" pattern.

Closes #3962

@TarantoolBot document
Title: Column naming in SQL

Now, every auto generated column is named by the "_COLUMN_N"
pattern, where N is the number of column in a query. Auto
generated column is a column in a query result generated by an
expression or a column from <VALUES> construction.
