SELECT f1 FROM (SELECT (t0.c0 - ADDDATE('2024-01-01', 1)) AS f1 FROM t0) as t WHERE f1; |
SQL2:
SELECT f1 FROM (SELECT (t0.c0 - ADDDATE('2024-01-01', 1)) AS f1, (t0.c0 - ADDDATE('2024-01-01', 1)) IS TRUE AS flag FROM t0) as t WHERE flag=1; |
How to repeat
DROP DATABASE IF EXISTS database0; |
CREATE DATABASE database0; |
