Details

Type: Bug
Status: Open (View Workflow)
Priority: Minor
Resolution: Unresolved
Affects Version/s: 10.5, 10.4(EOL)
Fix Version/s: 10.5
Component/s: Server
Labels:
- not-10.6+

Description

Set to Minor because the failures are only reproducible with the provided test case on 10.4-10.5.

CREATE TABLE t (a VARCHAR(32), KEY(a)) CHARACTER SET utf8;

INSERT INTO t VALUES ('foo'),('bar');

CREATE ALGORITHM=TEMPTABLE VIEW v AS SELECT * FROM t;

SELECT * FROM v WHERE a < FROM_UNIXTIME(1568145408, '%I');

# Cleanup

DROP VIEW v;

DROP TABLE t;
