SQL: cannot change column name casing in the query result about 1 year ago

AI Summary: The task is to investigate why QuestDB's SQL query results do not reflect the specified column name casing in the `SELECT` statement (e.g., `SELECT symbol AS SYMBOL` returns `symbol` instead of `SYMBOL`). The issue needs debugging to determine if this is a bug or an intended behavior, and a fix or documentation update may be required.

[Enhancement] Add IF EXISTS to truncate table over 1 year ago
