Description
Attempting to create a view with a WITH clause crashes every time.
Steps to reproduce:
|
|
MariaDB [(none)]> CREATE TABLE test.tbl1 ( f CHAR(1));
|
Query OK, 0 rows affected (0.019 sec)
|
|
|
MariaDB [(none)]> CREATE VIEW test.vw1 AS WITH t1 AS (SELECT * FROM test.tbl1) SELECT * FROM t1;
|
ERROR 2013 (HY000): Lost connection to MySQL server during query

I have grabbed the core file, will provide if needed
mysql log:

This could be because you hit a bug. It is also possible that this binary
|
or one of the libraries it was linked against is corrupt, improperly built,
|
or misconfigured. This error can also be caused by malfunctioning hardware.
|

|

|
We will try our best to scrape up some info that will hopefully help
|
diagnose the problem, but since we have already crashed,
|
something is definitely wrong and this may fail.

|
read_buffer_size=131072
|
max_used_connections=1
|
max_threads=153
|

|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 467756 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.

We have a problem already with derived tables used in views:
Here's a test case demonstrating the problem:
drop database test; |
create database test; |
create table test.t1 (a int); |
insert into test.t1 values (3),(7),(1); |
create view test.v2 as select * from (select * from test.t1) as t; |
select test.v2.a from test.v2; |
MariaDB [(none)]> select test.v2.a from test.v2;
|
ERROR 1356 (HY000): View 'test.v2' references invalid table(s) or column(s) or function(s) or definer/invoker of view lack rights to use them
|
Thanks a lot! I repeated on 10.2-10.5. (test uses CTE, so I checked only 10.2+ )
I could not reproduce the test at first as I didn't notice that in the demonstrated case client does not have a default database to use.
To run mtr-test I delete and recreate db test:
