Description
When using Spider storage engine on MariaDB 10.5 to connect to a MariaDB 10.6 remote server, if the spider table in your query has an index and is used as part of the query you will get
ERROR 12710 (HY000): Invalid information from remote table 'employees.dept_emp'
|
If you run the following command you get the same error
show index from emp_spider.dept_emp;
|
ERROR 12710 (HY000): Invalid information from remote table 'employees.dept_emp'
|
This issue easily reproducible.
- Create a 10.6 server and load the following schema onto it https://github.com/datacharmer/test_db
- Create a user to use for spider access
- Then build a 10.5 server
- Load the emp_spider_repro.sql schema onto the 10.5 server
- Be sure use the correct details for creating the server for Spider engine to use
- Run the following commands on the 10.5 server
show index from emp_spider.dept_emp; |
select count(*) from emp_spider.employees; |
select count(*) from emp_spider.employees where emp_no between 1 and 40000; |
The first and last command will return with an error but the second command will succeed
