While separately each part of the test case is fairly normal, together they make such a weird mix of optimizer features, InnoDB, locking, temporary tables, and virtual columns that it can't all be relevant. However, I couldn't get rid of any remaining component.
--source include/have_innodb.inc

CREATE TEMPORARY TABLE t1 (a INT, b INT AS (a*2), c CHAR(3), KEY(b), KEY(c)) ENGINE=InnoDB;
|
INSERT INTO t1 (a,c) VALUES
|
(9,'SRB'),(3,'PRT'),(2,'KAZ'),(6,'QAT'),(9,'FRA'),(1,'VAT'),(8,'SVN'),
|
(6,'PRT'),(7,'OMN'),(9,'QAT'),(9,'TUR'),(5,'CUB'),(9,'VEN'),(4,'USA'),
|
(5,'YEM'),(2,'VNM'),(2,'YEM'),(1,'MEX'),(2,'NLD'),(1,'NOR'),(4,'ARG'),
|
(8,'FRA'),(6,'NOR');
|
|
CREATE TABLE t2 (x INT);
|
LOCK TABLE t2 READ;
|
|
SELECT * FROM t1 WHERE b > 17 AND c IN ('QAT', 'PRT', 'FIN');
|
|
# Cleanup
|
UNLOCK TABLES;
|
DROP TABLE t2;
|
The expected result is one row (9, 18, 'QAT').
The actual result on a non-debug build is an empty set.
A debug build produces an assertion failure:
