问题
I am trying to change a column name in an AWS Athena table.
From old_name to new_name.
Normal DDL commands does not affect the table (They cannot be executed).
Is It possible to change a column name without deleting and re-creating the table from scratch ?
回答1:
I was mistaken, Athena uses HIVE DDL syntax so the correct command is :
ALTER TABLE %%table-name%% CHANGE %%old-column-name%% %%new-column-name%%<string>;
I based my answer on a hive related question.
