# Bug 35333 "If a Federated table can't connect to the remote hose, can't retrieve metadata"
#
# Queries such as SHOW TABLE STATUS and SELECT * FROM INFORMATION_SCHEMA.TABLES fail
# when encountering a federated table that cannot connect to its remote table.
#
# The fix is to store the error text in the TABLE COMMENTS column of I_S.TABLES, clear
# the remote connection error and push a warning instead. This allows the SELECT operation
# to complete while still indicating a problem. This fix applies to any non-fatal system
# error that occurs during a query against I_S.TABLES.de
CREATE DATABASE federated;
CREATE DATABASE federated;
DROP TABLE IF EXISTS federated.t0;
#
# Create a MyISAM table then corrupt the file
#
CREATE TABLE t1 (c1 int) ENGINE=MYISAM;
#
# Corrupt the MyISAM table by deleting the base file
#
#
# Trigger a MyISAM system error during an INFORMATION_SCHEMA.TABLES query
#
SELECT TABLE_SCHEMA, TABLE_NAME, TABLE_TYPE, ENGINE, ROW_FORMAT, TABLE_ROWS, DATA_LENGTH, TABLE_COMMENT
FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME = 't1';
TABLE_SCHEMA TABLE_NAME TABLE_TYPE ENGINE ROW_FORMAT TABLE_ROWS DATA_LENGTH TABLE_COMMENT
test t1 BASE TABLE NULL NULL NULL NULL Can't find file: './test/t1.MYI' (errno: 2 "No such file or directory")
Warnings:
Warning 1017 Can't find file: './test/t1.MYI' (errno: 2 "No such file or directory")
DROP TABLE t1;
Warnings:
Warning 2 Can't find file: './test/t1.MYI' (errno: 2 "No such file or directory")
#
# Cleanup

DROP TABLE IF EXISTS federated.t1;
DROP DATABASE IF EXISTS federated;
DROP TABLE IF EXISTS federated.t1;
DROP DATABASE IF EXISTS federated;
