Description

INSTALL PLUGIN Spider SONAME 'ha_spider.so';

CREATE USER Spider@localhost IDENTIFIED BY 'PWD1';

CREATE SERVER srv FOREIGN DATA WRAPPER MYSQL OPTIONS (SOCKET '../socket.sock',DATABASE 'test',user 'Spider',PASSWORD 'PWD1');

CREATE TABLE t (c INT) ENGINE=InnoDB;

CREATE TABLE ts (c1 INT) ENGINE=Spider COMMENT='WRAPPER "mysql",srv "srv",TABLE "t"';

SELECT c1 FROM ts;

Leads to:

10.11.0 6ebdd3013a18b01dbecec76b870810329eb76586 (Debug)
10.11.0-dbg>SELECT c1 FROM ts;
ERROR 1054 (42S22): Unknown column 't0.c1' in 'field list'

1. The t0 is incorrect, there is no t0 defined. This is likely a Spider-internal reference.
2. The error is confusing. We could replace it with something like:

ERROR 1054 (42S22): Unknown column 'c1' in parent spider table 't'.

Or similar (assuming that this is the underlaying issue).

Changing the definition of table t to column name c1 (instead of c) fixes the issue.
