SELECT f1 FROM (SELECT ((t0.c0) - (TIMESTAMPADD(MICROSECOND, 4 , '2023-04-18'))) AS f1 FROM t0) as t WHERE f1; |
SQL2:
SELECT f1 FROM (SELECT ((t0.c0) - (TIMESTAMPADD(MICROSECOND, 4 , '2023-04-18'))) AS f1, ((t0.c0) - (TIMESTAMPADD(MICROSECOND, 4 , '2023-04-18'))) IS TRUE AS flag FROM t0) as t WHERE flag=1; |
How to repeat
DROP DATABASE IF EXISTS database0; |
CREATE DATABASE database0; |
