Description
In theory, sql1 and sql2 should return the same result, however,sql1 return Empty set while sql2 return 0.0000
SQL1:
SELECT f1 FROM (SELECT (t0.c0) / (PERIOD_ADD(196802,2)) AS f1 FROM t0) AS t WHERE f1; |
SQL2:
SELECT f1 FROM (SELECT (t0.c0) / (PERIOD_ADD(196802,2)) AS f1, ((t0.c0) / (PERIOD_ADD(196802,2))) IS TRUE AS flag FROM t0) AS t WHERE flag=1; |
How to repeat
DROP DATABASE IF EXISTS database0; |
CREATE DATABASE database0; |
USE database0; |
CREATE TABLE t0(c0 INT) ; |
INSERT INTO t0(c0) VALUES(0.6799213532830038); |
