Ok I guess. Yet the sqlite_version() function also takes no arguments but the parentheses are required. Regardless it's no biggie.
SQLite version 3.31.1 2020-01-27 19:55:54
Enter ".help" for usage hints.
Connected to a transient in-memory database.
Use ".open FILENAME" to reopen on a persistent database.
sqlite> select current_date;
2020-06-13
sqlite> select current_date();
Error: near "(": syntax error
sqlite> select sqlite_version;
Error: no such column: sqlite_version
sqlite> select sqlite_version();

Thanks guys
