【重现步骤】
1、创建表 t1，插入记录
create table t1(pk int, col_int int)engine=innodb;
insert into t1 values(6,6),(8,8),(5,5);
SELECT pk AS field1 FROM t1 WHERE pk = 6 GROUP BY field1 HAVING (field1 = 8 OR field1 = ( SELECT pk FROM t1 WHERE col_int = 5 limit 1));
2、执行以下查询
语句一
SELECT pk AS field1 FROM t1 WHERE pk = 6 GROUP BY field1 HAVING (field1 = 8 OR field1 = ( SELECT pk FROM t1 WHERE col_int = 5 limit 1));
语句二
SELECT pk AS field1 FROM t1 GROUP BY field1 HAVING (field1 = 8 OR field1 = ( SELECT pk FROM t1 WHERE col_int = 5 limit 1));
【预期结果】
正确返回结果
【实际结果】
MariaDB server core dump
【备注】
语句一导致 MariaDB server core dump 后，堆栈如下：
