Hi, I have server version: 5.0.18, if I make a query like this: select [whatever] from table1 a, table2 b; It returns: ERROR 1017: Can't find file: 'b' (errno: 2) The query worked in the previous server version 4.x. If I am using just one alias in query: select [whatever] from table1 a; the query returns correctly.

To Szasz Attila: Sorry, I am not able to repeat with 5.0.18. Look: mysql> show tables like 'tt%'; +----------------------+ | Tables_in_test (tt%) | +----------------------+ | tt1 | | tt2 | | tt3 | +----------------------+ 3 rows in set (0.00 sec) mysql> select * from tt1 a, tt2 b; Empty set (0.00 sec) mysql> select version(); +-----------+ | version() | +-----------+ | 5.0.18-nt | +-----------+ 1 row in set (0.02 sec)

Sorry, I didn't checked the OS... here is Windows, I am using Linux (FC5). Perhaps someone can move my comment to the right place? I cannot find the Linux section.

As addition to my above post, I was able to repeat the error on FreeBSD 6.1 PRERELEASE, mysql 4.1.18 using the same steps I took for the first two tables (det, det2). mysql> create table dd(d date, dt timestamp, t timestamp) engine=merge union=(d1,d2); Query OK, 0 rows affected (0.04 sec) mysql> select * from dd; ERROR 1016 (HY000): Can't open file: 'dd.MRG' (errno: 143) mysql> select version(); +-----------+ | version() | +-----------+ | 4.1.18 | +-----------+ 1 row in set (0.01 sec)

It is still not a bug, because, according to the manual (http://dev.mysql.com/doc/refman/5.0/en/merge-storage-engine.html): "The MERGE storage engine, also known as the MRG_MyISAM engine, is a collection of identical MyISAM tables that can be used as one. “Identical” means that all tables have identical column and index information. You cannot merge MyISAM tables in which the columns are listed in a different order, do not have exactly the same columns, or have the indexes in different order."

Sorry for not testing the 2nd and 3rd table (same table specs) merge on FreeBSD. It works and I am able to retrieve info (select *). But the one on Windows remains the same. It still says the same error 1017. I re-tested on Windows using the same lines I used on BSD that worked. And for a change, mysql> create table s1 (id int); Query OK, 0 rows affected (0.13 sec) mysql> create table s2 (id int); Query OK, 0 rows affected (0.09 sec) mysql> create table s3 (id int) engine=merge union=(s1,s2); Query OK, 0 rows affected (0.05 sec) mysql> select * from s3; ERROR 1017 (HY000): Can't find file: 's3' (errno: 2) ...winxp

I've found my problem and it could have been the case for the submitter of this bug report. I had my tables default to innodb. Specifying engine=myisam on creation or altering the table to engine=myisam makes Merge work as expected. And it doesn't matter if the merge table has already been created. I did the same on the first two tables that was not identical and I'm pleased with the helpful error message saying, ERROR 1168 (HY000): All tables in the MERGE table are not identically defined

Hello Everyone, To migrate my database faster, I tried copying the raw files (MYD and MYI) files of a database into another machine. All the tables are working fine except two tables that were partitioned. My directory structure looks like this: table1.frm table1.MYI table1.MYD table2.frm table2.par table2#P#p0.MYD table2#P#p0.MYI table2#P#p1.MYD table2#P#p1.MYI table3.frm table3.par table3#P#p0.MYD table3#P#p0.MYI table3#P#p1.MYD table3#P#p1.MYI The following is producing an error: mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | test | +--------------------+ 3 rows in set (0.06 sec) mysql> use test; Database changed mysql> show tables; +---------------------------+ | Tables_in_test | +---------------------------+ | table1 | | table2 | | table3 | +---------------------------+ 3 rows in set (0.00 sec) mysql> explain table1; +-------+---------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +-------+---------+------+-----+---------+----------------+ | id | int(11) | NO | PRI | NULL | auto_increment | | a | int(11) | YES | | NULL | | +-------+---------+------+-----+---------+----------------+ 2 rows in set (0.01 sec) mysql> explain table2; ERROR 1017 (HY000): Can't find file: 'table2' (errno: 2) mysql> explain table3; ERROR 1017 (HY000): Can't find file: 'table3' (errno: 2) mysql> check TABLE table2; +--------------------------+-------+----------+--------------------------------------------------+ | Table | Op | Msg_type | Msg_text | +--------------------------+-------+----------+--------------------------------------------------+ | test.table2 | check | Error | Can't find file: 'table2' (errno: 2) | | test.table2 | check | error | Corrupt | +--------------------------+-------+----------+--------------------------------------------------+ 2 rows in set (0.00 sec) I checked the permissions and everything looks fine. I tried repair but that didn't seem to work either. Is there anything that can be done?
